pharmachologic effect

Synthetic analogue of somatostatin, which has similar pharmacological effects, but with a much longer duration of action.

The drug suppresses the secretion of growth hormone, both pathologically increased and caused by arginine, physical activity and insulin hypoglycemia. The drug also suppresses the secretion of insulin, glucagon, gastrin, serotonin, both pathologically increased and caused by food intake; also suppresses the secretion of insulin and glucagon, stimulated by arginine. Octreotide inhibits thyrotropin secretion caused by thyreoliberin.

In patients scheduled for pancreatic surgery, the use of octreotide before, during, and after surgery reduces the incidence of typical postoperative complications(eg, pancreatic fistulas, abscesses, sepsis, acute postoperative pancreatitis).

When bleeding from varicose veins of the esophagus and stomach in patients with cirrhosis of the liver, the use of octreotide in combination with specific treatment (for example, sclerosing and hemostatic therapy) leads to more effective control of bleeding and prevention of rebleeding.

Pharmacokinetics

Suction

After subcutaneous administration, Octreotide is rapidly and completely absorbed. C max octreotide in plasma is achieved within 30 minutes.

Distribution

Plasma protein binding is 65%. Binding of Octreotide with blood cells is extremely insignificant. Vd is 0.27 l/kg.

breeding

After s / c injection of the drug T1 / 2 octreotide is 100 minutes. After intravenous administration, the excretion of octreotide is carried out in 2 phases with a T1 / 2 of 10 minutes and 90 minutes, respectively. Most of octreotide is excreted through the intestines, about 32% is excreted unchanged by the kidneys. The total clearance is 160 ml / min.

Pharmacokinetics in special clinical situations

In elderly patients, clearance decreases, and T1 / 2 increases.

With severe kidney failure clearance is reduced by 2 times.

Pharmacodynamics

Octreotide is a synthetic analog of somatostatin with similar pharmacological effects, but a much longer duration of action. Octreotide suppresses the secretion of growth hormone (GH), both pathologically increased and caused by arginine, exercise and insulin hypoglycemia. The drug also suppresses the secretion of insulin, glucagon, gastrin, serotonin, both pathologically increased and caused by food intake; also suppresses the secretion of insulin and glucagon, stimulated by arginine. Octreotide inhibits thyrotropin secretion caused by thyreoliberin.

In patients scheduled for pancreatic surgery, the use of octreotide before, during and after surgery reduces the incidence of typical postoperative complications (eg, pancreatic fistulas, abscesses, sepsis, acute postoperative pancreatitis). When bleeding from varicose veins of the esophagus and stomach in patients with liver cirrhosis, the use of octreotide in combination with specific treatment (for example, sclerosing and hemostatic therapy) leads to more effective control of bleeding and prevention of rebleeding.

  • Treatment of acute pancreatitis;
  • stop bleeding at peptic ulcer stomach and duodenum;
  • stop bleeding and prevention of rebleeding from esophageal varices in patients with cirrhosis of the liver;
  • prevention and treatment of complications after organ operations abdominal cavity.

Contraindications for use

  • Children's age up to 18 years;
  • hypersensitivity to octreotide or other components of the drug.

With caution: cholelithiasis ( cholelithiasis), diabetes, pregnancy, lactation.

Use in pregnancy and children

The use of octreotide during pregnancy has not been studied. Octreotide should only be used during pregnancy if the potential benefit to the mother outweighs the potential risk to the fetus.

It is not known if the drug enters breast milk therefore, when using the drug during lactation, breastfeeding should be abandoned.

Use in children

Contraindicated in children under the age of 18

Side effects

From the gastrointestinal tract and pancreas: possible - anorexia, nausea, vomiting, abdominal cramps, a feeling of bloating, excessive gas formation, liquid stool, diarrhea, steatorrhea. Although fecal fat excretion may increase, there is no indication that long-term treatment octreotide can lead to the development of malabsorption. In rare cases, there may be phenomena resembling acute intestinal obstruction. There are isolated cases of acute hepatitis without cholestasis, hyperbilirubinemia in combination with an increase in the activity of alkaline phosphatase, GGT and, to a lesser extent, other transaminases.

Prolonged use of octreotide can lead to the formation of stones in gallbladder.

From the side cordially- vascular system: in some cases - arrhythmia, bradycardia.

On the part of carbohydrate metabolism: a violation of glucose tolerance after a meal is possible (due to the suppression of insulin secretion by the drug), hypoglycemia; in rare cases, with prolonged treatment, persistent hyperglycemia may develop.

Local reactions: at the injection site, pain, itching or burning sensation, redness, swelling are possible (usually disappear within 15 minutes).

Others: allergic reactions, alopecia.

drug interaction

Octreotide reduces the absorption of cyclosporine, slows down the absorption of cimetidine.

It is necessary to correct the dosing regimen of simultaneously used diuretics, beta-blockers, blockers of "slow" calcium channels, insulin, oral hypoglycemic drugs.

With the simultaneous use of Octreotide and bromocriptine, the bioavailability of the latter increases.

Drugs metabolized by enzymes of the cytochrome P450 system and having a narrow therapeutic dose range should be administered with caution.

Dosage

For the treatment of acute pancreatitis, the drug is administered s / c at a dose of 100 mcg 3 times / day for 5 days. Perhaps the appointment of up to 1200 mcg / day using the / in the route of administration.

To stop ulcerative bleeding, it is administered intravenously at a dose of 25-50 mcg / h as an intravenous infusion for 5 days.

To stop bleeding from varicose veins of the esophagus, it is administered intravenously at a dose of 25-50 mcg / h in the form of continuous intravenous infusions for 5 days.

In elderly patients, there is no need to reduce the dose of Octreotide.

To prevent complications after operations on the pancreas, the first dose of 100-200 mcg is administered s / c 1-2 hours before laparotomy; then after the operation, s / c is injected at 100-200 mcg 3 times / day for 5-7 consecutive days.

Overdose

Symptoms: a short-term decrease in heart rate, a feeling of "rush" of blood to the face, spastic pain in the abdomen, diarrhea, nausea, a feeling of emptiness in the stomach.

Treatment: symptomatic.

Precautionary measures

In diabetic patients receiving insulin, octreotide may reduce the need for insulin.

If gallstones are identified prior to treatment, the use of octreotide is decided on an individual basis, depending on the relationship between the potential therapeutic effect of the drug and possible risk factors associated with the presence of gallstones.

Gastrointestinal side effects may be reduced if octreotide injections are given between meals or at bedtime.

To reduce the symptoms of discomfort at the injection site, it is recommended to bring the drug solution to room temperature before administration and inject a smaller volume of the drug. Multiple injections at the same site at short intervals should be avoided.

Influence on the ability to drive vehicles and control mechanisms

Some side effects octreotide may adversely affect the ability to drive vehicles and other mechanisms that require increased concentration of attention and speed of psychomotor reactions.

Octreotide is a synthetic derivative of the natural hormone somatostatin, characterized by similar pharmacological effects, but a much longer duration of action; inhibits the secretion of thyrotropin, serotonin, gastrin, insulin, glucagon, growth hormone, both pathologically elevated and conditioned external factors(arginine, food intake, insulin hypoglycemia, etc.).

The solution is used for the treatment and prevention of complications in the period after surgery on the abdominal cavity, as well as in patients with cirrhosis of the liver to stop bleeding and prevent re-bleeding from varicose veins of the stomach and esophagus. The use of the agent is possible in combination with specific therapeutic measures (for example, with endoscopic sclerotherapy).

Contraindications

  • Children's and adolescence up to 18 years;
  • Hypersensitivity to the components of the drug.

With extreme caution, the drug should be used for cholelithiasis (cholelithiasis) and diabetes mellitus. Experience with the use of the drug during pregnancy is not available. As a result, Octreotide is recommended for pregnant women only when the expected benefit of therapy outweighs the potential risk of adverse reactions.

If it is necessary to administer the drug during lactation, it is required to refuse breastfeeding (because it is not known whether the drug passes into breast milk).

Method of application and dosage

Octreotide is used subcutaneously and intravenously.

In the treatment of acute pancreatitis, 100 mcg of the solution is administered subcutaneously 3 times a day for 5 days; intravenous infusion at a dose not exceeding 1200 mcg per day is also acceptable.

To stop bleeding from varicose veins of the esophagus or peptic ulcer, long-term intravenous infusions are prescribed at a dose of 25-50 mcg / hour for 5 days.

In order to prevent complications after undergoing surgical interventions on the pancreas, the agent is administered subcutaneously. The first injection at a dose of 100-200 mcg is carried out 1-2 hours before laparotomy, and the next - at a dose of 100-200 mcg after surgery, 3 times a day, daily for 5-7 days.

In acromegaly, it is recommended to administer 300 micrograms of Octreotide subcutaneously at intervals of 8 or 12 hours, this dose is prescribed if there is no effect during initial therapy (50-100 micrograms of solution at intervals of 8 or 12 hours). The effectiveness of treatment is determined by taking into account monthly concentrations growth hormone in the blood, drug tolerance and clinical symptoms. To achieve the desired effect, if necessary, it is possible to use the drug in a dose exceeding 300 mcg, but not more than 1500 mcg per day.

If there is no improvement within 3 months of therapy clinical picture and a sufficient decrease in the level of growth hormone, the use of the drug is impractical.

For tumors of the gastroenteropancreatic endocrine system the drug is administered subcutaneously. The initial dose of Octreotide is 50 mcg, applied 1-2 times a day, in the future it is possible to increase the dose to 100-200 mcg with a frequency of administration 3 times a day. With the ineffectiveness of initial therapy, assessed by the concentration of hormones produced by the tumor, the tolerability of the drug and the achieved clinical effect, appoint 1-2 times a day subcutaneous injections at a dose of 300 mcg. In exceptional cases, a gradual increase in dose to 300-600 mcg, administered 3 times a day, is acceptable. If during the treatment of carcinoid tumors with Octreotide at the maximum tolerated dose, there is no therapeutic effect within 7 days, treatment should be discontinued.

Elderly people and patients with functional disorders kidney does not require correction of the dosing regimen.

When prescribing an intravenous drip infusion of the drug, the contents of the ampoule at a dose of 600 μg must be dissolved in 60 ml of physiological sodium chloride solution (0.9%). Diluted solutions must be administered immediately after preparation (to avoid microbial contamination). If it is impossible to use the drug immediately after dilution, it can be stored at a temperature of 2-8 ° C for no longer than 24 hours ( total time from the moment of dilution until the end of its introduction).

  • Endocrine system: very often - hyperglycemia; often - hypothyroidism, impaired activity thyroid gland(decrease in the levels of free and total thyroxine, and thyroid-stimulating hormone); impaired glucose tolerance, hypoglycemia;
  • Hepatobiliary system: very often - the formation of stones in the gallbladder (cholelithiasis); often - increased activity of hepatic transaminases, hyperbilirubinemia, impaired colloidal stability of bile, cholecystitis;
  • Nervous system: very often - headache; often - dizziness;
  • Cardiovascular system: often - bradycardia; sometimes - tachycardia;
  • Respiratory system: often - shortness of breath;
  • Skin: often - itching, rash, hair loss;
  • General disorders and local reactions: very often - pain at the injection site; sometimes dehydration.

Also, when using the drug in clinical practice the following undesirable effects were observed (regardless of the presence of a causal relationship with the use of the agent): cholestatic jaundice, cholestasis, jaundice, cholestatic hepatitis, acute hepatitis without the phenomena of cholestasis, acute pancreatitis, increased levels of gamma-glutamyl transferase (GGT) and alkaline phosphatase (AP), arrhythmia, allergic reactions, urticaria, anaphylactic reactions.

With subcutaneous injections of octreotide at a daily dose of 3000-30000 mcg, divided into several injections, no new side effects were detected in patients with tumors (other than those indicated above).

With accidental intravenous administration of the drug at a dose of 2400-6000 mcg per day (at a rate of 100-250 mcg / h) or subcutaneous administration of 1500 mcg 3 times a day, the following reactions were observed: weight loss, lactic acidosis, hepatomegaly, lethargy, weakness, diarrhea, fatty degeneration of the liver, pancreatitis, cerebral hypoxia, sudden cardiac arrest, decreased blood pressure development of arrhythmias. Treatment is symptomatic.

special instructions

Patients with diabetes who take insulin may experience a decrease in insulin requirements during therapy.

Before starting treatment, as well as during a long course, it is recommended to conduct an ultrasound examination of the gallbladder at intervals of 6-12 months.

In the case of detection of stones in the gallbladder before the start of therapy, the issue of using the drug is decided individually, after the ratio of the potential benefits of therapy and the risk of developing possible complications associated with the presence of stones.

Manifestations of adverse reactions from digestive system may be reduced by administering octreotide at bedtime or between meals.

With a long course, thyroid function should be monitored.

In rare cases, during the treatment of endocrine tumors of the gastrointestinal tract and pancreas, there may be a sudden relapse of the symptoms of the disease.

When using octreotide in patients with a history of vitamin B12 (cobalamin) deficiency, it is recommended to control its content in the body (the absorption of cobalamin worsens).

To reduce discomfort and pain at the injection site, it is recommended to warm the solution to room temperature before use and inject it in a smaller volume. Injections of the drug at short intervals at the same injection site should be avoided.

drug interaction

The effect of octreotide on concomitantly taken substances / drugs:

  • Cyclosporine - reduces its absorption;
  • Bromocriptine - increases its bioavailability;
  • Cimetidine - slows down its absorption;
  • Drugs metabolized by the cytochrome P450 system (terfenadine, quinidine) - reduces their metabolism.

When octreotide is combined with diuretics, oral hypoglycemic drugs, insulin, slow calcium channel blockers, beta-blockers, a correction of the dosing regimen is required.

Terms and conditions of storage

Store in a place protected from moisture and light, out of the reach of children, at a temperature of 8 to 25 °C.

Shelf life - 5 years.

Synthetic derivative of the hormone somatostatin, which has similar pharmacological effects and a much longer duration of action. Reduces the secretion of growth hormone, TSH, has an antithyroid, antispasmodic effect. Reduces acid production, gastrointestinal motility. Suppresses pathologically increased secretion of growth hormone, peptides and serotonin produced in the gastroentero-pancreatic endocrine system.

Normally, it reduces the secretion of growth hormone caused by arginine, stress and insulin hypoglycemia; secretion of insulin, glucagon, gastrin, and other peptides of the gastroentero-pancreatic endocrine system, caused by food intake, as well as the secretion of insulin and glucagon, stimulated by arginine; thyrotropin secretion caused by thyroliberin.

Suppression of growth hormone secretion by octreotide (unlike somatostatin) occurs to a much greater extent than by insulin. The introduction of octreotide is not accompanied by the phenomenon of hormone hypersecretion by the "negative feedback" mechanism. In patients with acromegaly, it reduces the concentration of growth hormone and / or somatomedin A in plasma. A clinically significant decrease in the concentration of growth hormone (by 50% or more) is observed in almost all patients, while the normalization of the content of growth hormone in plasma (less than 5 ng / ml) is achieved in about half of the patients.

In carcinoid tumors, the administration of octreotide can lead to a decrease in the severity of the symptoms of the disease, primarily such as "flushing" of blood to the skin of the face and diarrhea, clinical improvement is accompanied by a decrease in plasma serotonin concentration and excretion of 5-hydroxyindoleacetic acid in the urine.

In tumors characterized by hyperproduction of vasoactive intestinal peptide (VIP), a decrease in severe secretory diarrhea, which is characteristic of given state which in turn improves the quality of life of the patient. At the same time, there is a decrease in concomitant electrolyte imbalances, such as hypokalemia, which makes it possible to cancel enteral and parenteral administration of fluids and electrolytes. It is possible to slow down or stop the progression of the tumor and even reduce its size and especially liver metastases. Clinical improvement is usually accompanied by a decrease (up to normal values) plasma VIP concentrations.

In glucagonomas, despite a marked reduction in necrotizing migratory rash, it does not have any significant effect on the severity of diabetes mellitus (often observed in glucagonomas) and usually does not lead to a decrease in the need for insulin or oral hypoglycemic drugs. In patients suffering from diarrhea, causes its decrease, which is accompanied by an increase in body weight, often noted rapid decline plasma glucagon concentrations, however, this effect does not persist with long-term treatment. At the same time, symptomatic improvement remains stable long time.

In gastrinomas (Zollinger-Ellison syndrome), octreotide, used as monotherapy or in combination with H2 receptor blockers and proton pump inhibitors, can reduce the formation of HCl in the stomach, it is possible to reduce the severity and other symptoms, probably associated with the synthesis of peptides by the tumor, including "tides". In some cases, there is a decrease in the concentration of gastrin in plasma.

In patients with insulinomas, it reduces the concentration of immunoreactive insulin in the blood (this effect, however, can be short-lived - about 2 hours).

In patients with resectable tumors, it can ensure the restoration and maintenance of normoglycemia in the preoperative period. In patients with inoperable benign and malignant tumors normoglycemia can be achieved without a simultaneous prolonged decrease in blood insulin.

In patients with rare tumors that hyperproduce growth hormone releasing factor (somatoliberinoma), it reduces the severity of symptoms of acromegaly. This appears to be due to suppression of the secretion of growth hormone releasing factor and growth hormone itself. In the future, it is possible to reduce the size of the pituitary gland, which were increased before the start of treatment.

In patients with acromegaly, the administration of octreotide provides, in the vast majority of cases, a persistent decrease in growth hormone and normalization of the concentration of insulin-like growth factor 1 / somatomedin C (IGF1). Significantly reduces the severity of symptoms such as headache, increased sweating, paresthesia, fatigue, bone and joint pain, peripheral neuropathy. In patients with pituitary adenomas that secrete growth hormone, it is possible to reduce the size of the tumor.

Sandostatin LAR is dosage form long-acting octreotide, designed to be administered at intervals of 4 weeks, which ensures the maintenance of stable therapeutic serum concentrations of octreotide. The composition of the microspheres includes a polymer matrix that serves as a carrier active substance. After i / m administration, as a result of the destruction of microspheres in muscle tissue, a prolonged and gradual release of the active substance occurs.

pharmachologic effect

Octreotide-depot is a long-acting intramuscular formulation of octreotide that maintains stable therapeutic concentrations of octreotide in the blood for 4 weeks. Octreotide is a synthetic octapeptide that is an analogue of the natural hormone somatostatin and has pharmacological effects similar to it, but with a significantly longer duration of action. The drug suppresses pathologically increased secretion of growth hormone, as well as peptides and serotonin produced in the gastroenteropancreatic endocrine system. In healthy individuals, octreotide, like somatostatin, inhibits growth hormone secretion induced by arginine, exercise, and insulin hypoglycemia; secretion of insulin, glucagon, gastrin and other peptides of the gastroenteropancreatic endocrine system caused by food intake, as well as secretion of insulin and glucagon stimulated by arginine; thyrotropin secretion caused by thyroliberin. The inhibitory effect on growth hormone secretion in octreotide, in contrast to somatostatin, is much more pronounced than on insulin secretion. The introduction of octreotide is not accompanied by the phenomenon of hormone hypersecretion by the negative feedback mechanism. In patients with acromegaly, the administration of Octreotide-depot in the overwhelming majority of cases provides a stable decrease in the level of growth hormone and normalization of the concentration of insulin-like growth factor 1 / somatomedin C (IGF-1). In most patients with acromegaly, Octreotide-depot significantly reduces the severity of symptoms such as headache, increased sweating, paresthesia, fatigue, pain in the bones and joints, and peripheral neuropathy. Treatment with octreotide in selected patients with growth hormone-secreting pituitary adenomas has been reported to reduce tumor size. In carcinoid tumors, the use of octreotide can lead to a decrease in the severity of the symptoms of the disease, in the first place, such as hot flashes and diarrhea. In many cases, clinical improvement is accompanied by a decrease in plasma serotonin concentration and urinary excretion of 5-hydroxyindoleacetic acid. In tumors characterized by hyperproduction of vasoactive intestinal peptide (VIPoma), the use of octreotide in most patients leads to a decrease in severe secretory diarrhea, which is characteristic of this condition, which, in turn, leads to an improvement in the quality of life of the patient. At the same time, there is a decrease in concomitant electrolyte imbalances, for example, hypokalemia, which makes it possible to cancel enteral and parenteral administration of fluids and electrolytes. According to computed tomography some patients slow down or stop the progression of the tumor, and even reduce its size, especially liver metastases. Clinical improvement is usually accompanied by a decrease (down to normal values) in the concentration of vasoactive intestinal peptide (VIP) in plasma. In glucagonomas, the use of octreotide in most cases leads to a marked reduction in the necrotizing migratory rash that is characteristic of this condition. Octreotide does not have any significant effect on the severity of diabetes mellitus, often observed in glucagonomas, and usually does not lead to a decrease in the need for insulin or oral hypoglycemic drugs. In patients suffering from diarrhea, octreotide causes its reduction, which is accompanied by an increase in body weight. With the use of octreotide, there is often a rapid decrease in plasma glucagon concentration, but this effect does not persist with long-term treatment. At the same time, symptomatic improvement remains stable for a long time. In gastrinomas/Zollinger-Ellison syndrome, octreotide, used as monotherapy or in combination with histamine H2 receptor blockers and proton pump inhibitors, can reduce the formation of hydrochloric acid in the stomach and lead to clinical improvement, incl. and for diarrhea. It is also possible to reduce the severity of other symptoms, probably associated with the synthesis of peptides by the tumor, incl. tides. In some cases, there is a decrease in the concentration of gastrin in plasma. In patients with insulinomas, octreotide reduces the level of immunoreactive insulin in the blood. In patients with resectable tumors, octreotide can restore and maintain normoglycemia in the preoperative period. In patients with inoperable benign and malignant tumors, glycemic control may improve without a simultaneous prolonged decrease in blood insulin levels. In patients with rare tumors that overproduce growth hormone releasing factor (somatoliberinoma), octreotide reduces the severity of symptoms of acromegaly. This appears to be due to suppression of the secretion of growth hormone releasing factor and growth hormone itself. In the future, it is possible to reduce the size of the pituitary gland, which were increased before the start of treatment. In patients with hormone-resistant prostate cancer, the pool of neuroendocrine cells expressing somatostatin affinity receptors for octreotide (SS2 and SS5 types) increases, which determines the sensitivity of the tumor to octreotide. The use of octreotide-depot in combination with dexamethasone against the background of androgen blockade (medical or surgical castration) in patients with hormone-resistant prostate cancer restores sensitivity to hormone therapy and leads to a decrease in prostate specific antigen (PSA) in more than 50% of patients. In patients with hormone-resistant prostate cancer with bone metastases, this therapy is accompanied by a pronounced and prolonged analgesic effect. At the same time, in all patients who responded to combination therapy with octreotide-depot, the quality of life and the median relapse-free survival significantly improved.

Pharmacokinetics

Absorption After subcutaneous administration, Octreotide is rapidly and completely absorbed. Cmax of octreotide in plasma is achieved within 30 minutes. Distribution Plasma protein binding is 65%. Binding of Octreotide with blood cells is extremely insignificant. Vd is 0.27 l/kg. Withdrawal The total clearance is 160 ml / min. About 32% is excreted unchanged by the kidneys. After s / c injection of the drug T1 / 2 octreotide is 100 minutes. After intravenous administration, the excretion of octreotide is carried out in 2 phases with a T1 / 2 of 10 minutes and 90 minutes, respectively. Pharmacokinetics in special clinical situations In elderly patients, clearance decreases, and T1 / 2 increases. In severe renal failure, clearance is reduced by 2 times.

Special conditions

Patients with GH-secreting pituitary tumors should be carefully monitored, as the size of tumors may increase with the development of such tumors. serious complications as a narrowing of the field of view. In these cases, the need for other treatments should be considered. In 15-30% of patients receiving octreotide s / c for a long time, the appearance of stones in the gallbladder is possible. The prevalence in the general population (age 40-60 years) is 5-20%. The experience of long-term treatment with prolonged-acting octreotide in patients with acromegaly and tumors of the gastrointestinal tract and pancreas indicates that prolonged-acting octreotide, in comparison with short-acting octreotide, does not lead to an increase in the incidence of gallbladder stones. However, gallbladder ultrasonography is recommended before initiation of octreotide treatment and approximately every 6 months during treatment. Gallstones, if found, are usually asymptomatic. In the presence of clinical symptoms, it is indicated conservative treatment(for example, the use of drugs bile acids) or surgery. In patients with type 1 diabetes mellitus, octreotide may affect glucose metabolism and, therefore, reduce the need for administered insulin. For patients with type 2 diabetes mellitus and patients without concomitant disturbance of carbohydrate metabolism, subcutaneous injections of octreotide can lead to postprandial glycemia. In this regard, it is recommended to regularly monitor the level of glycemia and, if necessary, correct hypoglycemic therapy. Patients with insulinomas during treatment with octreotide may experience an increase in the severity and duration of hypoglycemia (this is due to a more pronounced inhibitory effect on GH and glucagon secretion than on insulin secretion, and also with a shorter duration of the inhibitory effect on insulin secretion). Systematic monitoring of these patients is shown. Prior to the administration of octreotide, patients should undergo an initial gallbladder ultrasound. During treatment with octreotide, repeat ultrasounds of the gallbladder should be performed, preferably at intervals of 6-12 months. If gallstones are detected prior to treatment, the potential benefits of octreotide therapy should be weighed against the possible risks associated with the presence of gallstones. Currently, there is no evidence that octreotide adversely affects the course or prognosis of pre-existing gallstone disease. Management of patients who develop gallstones during treatment with octreotide. a) Asymptomatic gallbladder stones. The use of octreotide can be discontinued or continued - in accordance with the assessment of the benefit / risk ratio. In any case, no other action is required than to continue the inspections, making them more frequent if necessary. b) Gallbladder stones with clinical symptoms. The use of octreotide can be discontinued or continued - in accordance with the assessment of the benefit / risk ratio. In any case, the patient should be treated in the same way as in other cases of cholelithiasis with clinical manifestations. Medical treatment includes the use of combinations of bile acids (for example, chenodeoxycholic acid at a dose of 7.5 mg / kg / day in combination with ursodeoxycholic acid at the same dose) under ultrasound control - until the stones disappear completely.

Octreotide indications for use

  • Acromegaly (when adequate control of the manifestations of the disease is carried out due to the subcutaneous administration of octreotide, in the absence of a sufficient effect of surgical treatment and radiation therapy; to prepare for surgical treatment, for treatment between courses of radiotherapy until the development of a persistent effect, in inoperable patients). In the treatment of endocrine tumors of the gastrointestinal tract (GIT) and pancreas: carcinoid tumors with symptoms of carcinoid syndrome; insulinomas; VIPomas; gastrinomas (Zollinger-Ellison syndrome); glucagonomas (to control hypoglycemia in the preoperative period, as well as for maintenance therapy). In the treatment of endocrine tumors of the gastrointestinal tract (GIT) and pancreas: carcinoid tumors with symptoms of carcinoid syndrome; insulinomas; VIPomas; gastrinomas (Zollinger-Ellison syndrome); glucagonomas (to control hypoglycemia in the preoperative period, as well as for maintenance therapy). Somatoliberinomas (tumors characterized by hyperpigmentation)

Octreotide contraindications

  • - childhood up to 18 years; - hypersensitivity to octreotide or other components of the drug. With caution: cholelithiasis (cholelithiasis), diabetes mellitus, pregnancy, lactation.

Octreotide dosage

Octreotide side effects

  • Local reactions: possible pain, itching, or burning, redness or swelling at the injection site (usually disappear within 15 minutes). The severity of local reactions can be reduced if a room temperature solution is used, or a smaller volume of a more concentrated solution is administered. From the gastrointestinal tract: anorexia, nausea, vomiting, abdominal cramps, bloating, excessive gas formation, loose stools, diarrhea, steatorrhea. Although fecal fat excretion may increase, there is no evidence to date that long-term treatment with octreotide can lead to malnutrition due to malabsorption. In rare cases, there may be phenomena resembling acute intestinal. obstruction: progressive bloating, severe pain in the epigastric region, tension abdominal wall. Prolonged use of octreotide can lead to the formation of gallstones. The frequency of side effects from the gastrointestinal tract can be reduced by increasing the time intervals between meals and the introduction of octreotide. From the side of the pancreas: rare cases of acute pancreatitis have been reported that developed in the first hours or days of octreotide use. With prolonged use, there have been cases of pancreatitis associated with cholelithiasis. From the side of the liver: there are separate reports of the development of liver dysfunction (acute hepatitis without cholestasis with normalization of transaminase levels after the abolition of octreotide); slow development of hyperbilirubinemia, accompanied by an increase in alkaline phosphatase, gamma-glutamyl transferase and, to a lesser extent, other transaminases. Since the cardiovascular system: in some cases - bradycardia. From the side of metabolism: since octreotide has a suppressive effect on the formation of GH, glucagon and insulin, it can affect glucose metabolism. Perhaps a decrease in glucose tolerance after a meal. With prolonged use of octreotide s / c, in some cases, persistent hyperglycemia may develop. Hypoglycemia has also been observed. Other: In rare cases, temporary hair loss has been reported following the administration of octreotide. There are separate reports on the development of reactions hypersensitivity: rarely - skin allergic reactions; in some cases - anaphylactic reactions.

drug interaction

Octreotide reduces the absorption of cyclosporine, slows down the absorption of cimetidine. With the simultaneous use of octreotide and bromocriptine, the bioavailability of the latter increases. It is necessary to correct the dosing regimen of simultaneously used diuretics, beta-blockers, blockers of "slow" calcium channels, insulin, oral hypoglycemic medicines, glucagon. There is evidence that somatostatin analogs may reduce the metabolism of drugs metabolized by cytochrome P450 enzymes (may be due to growth hormone suppression). Since it is impossible to exclude similar effects of ocreotide, drugs metabolized by enzymes of the cytochrome P450 system and having a narrow therapeutic dose range should be prescribed with caution.

Overdose

It is known that the introduction of octreotide at a dose of up to 2000 mcg in the form of a subcutaneous injection 3 times over several months was well tolerated. The maximum single dose for intravenous bolus administration in an adult patient was 1000 mcg. At the same time, such symptoms were noted as a decrease in heart rate, "flushing" of blood to the face, abdominal pain of a spastic nature, diarrhea, nausea, and a feeling of emptiness in the stomach. All of these symptoms resolved within 24 hours of drug administration. One patient was given an overdose of octreotide 250 mcg/h (instead of 25 mcg/h) by mistake by continuous infusion, with no side effects. In acute overdose, no life-threatening reactions have been noted. Treatment: symptomatic therapy.

Storage conditions

  • store in a dry place
  • keep away from children

  • Intravenously using a dropper, when up to 1200 micrograms of the drug is administered to the patient daily for 15 days.
  • Subcutaneous injections are performed three times a day. Depending on the stage of the disease and the location of the pancreatic lesion, the daily dose for the first 5 days can be 50-300 micrograms of the drug, and subsequently the dosage is reduced, based on the existing symptoms.
  • For intramuscular injection a suspension lyophilisate is used, which is injected to the patient once a month.

Regardless of the method of using this drug, it is prohibited to prescribe Octreotide on your own. The medicine is dispensed in pharmacies exclusively by prescription, and a specialist can write it out only after complete examination sick.

With the wrong dosage and self-administration of the drug, serious damage to the pancreas is possible, up to the patient's disability.

special instructions

In the presence of a pituitary tumor, it is necessary to monitor the patient's condition, in particular, constantly monitor the size of the neoplasms and change the dosage of the drug accordingly. In the treatment of endocrine gastropancreatic tumors, a sudden acute relapse of symptoms may occur.

The introduction of Octreotide in pancreatitis in the intervals between sleep and meals can reduce side effects from the gastrointestinal tract. In order to identify an allergy to the drug, it is recommended to conduct a trial infusion, according to the results of which the doctor will decide on the appointment of this medication and its optimal dosage.

With long courses of treatment, which can reach 12 months, it is necessary to perform ultrasound of the gallbladder on a regular basis. This will allow diagnosing the appearance of stones in the ureters.

Gallstone disease is asymptomatic, respectively, revealing such formations on early stage, you can crush them with ultrasound, which will avoid the need for a complex operation.

During the treatment period, regardless of the duration of the course and dosage of the drug, systematic monitoring of the patient's condition is necessary. The physician should monitor the concentration of glucose in the blood, especially in patients with cirrhosis of the liver and varicose veins veins of the esophagus.

With correct diagnosis and timely administration of Octreotide, the prognosis is positive. Shortly after the start of injections and droppers, the patient feels better, and with long courses, complete recovery is possible even with severe forms illness.

Octreotide shows excellent results as a prevention of pancreatic diseases. The components contained in the preparation reduce the inflammation of this internal organ, regenerate its cells, eliminate all the symptoms of existing diseases.

High-quality treatment implies an integrated approach, including the correct selection of therapy, as well as adherence to a special diet that contains a minimum of fatty foods. This will ensure complete recovery even in the presence of chronic pathologies.
