Pharmacological action
Synthetic peptide, an analogue of the natural hormone somatostatin.
Like natural somatostatin, lanreotide inhibits pathologically increased secretion of growth hormone, and secretion of many peptides and other biologically active substances, produced in the gastro-entero-pancreatic endocrine system (incl. gastrin, insulin, glucagon, digestive enzymes, hydrochloric acid, vazointestinalny peptide, Serotonin).
It has a pronounced affinity for peripheral somatostatin receptors (pituitary and pancreatic), than the central. This is due to the selectivity of growth hormone secretion and pancreatic exocrine secretion and intestinal glands.
Pharmacokinetics
Absorption
Absorption lanreotide characterized the first phase of rapid release of the peptide, located on the surface of the microspheres, which is replaced by a second phase of slow release. Cmax Phase, component of 6.8 ± 3.8 mg / l, observed after 1.4 ± 0.8 h and Cmax Phase II, component of 2.5 ± 0.9 mg / l, It observed after 1.9 ± 1.8 days. The absolute bioavailability of 46.1 ± 16.7 %.
Distribution
The study of the binding of lanreotide to blood components showed, it is unlikely that such an interaction at this level.
Patients, suffering from acromegaly, and pharmacokinetics in healthy individuals similar. The concentration of growth hormone and insulin-like growth factor (RAF-1) falling within, at least, 14 days after a single injection. With the constant introduction of the drug for several months, the cumulation is not checked.
Deduction
The average retention time of 8 ± 1 days and T1/2 5.2± 2.5 days. These figures confirm a sustained release of the drug.
Testimony
- Akromegalija;
- Carcinoid tumors (as symptomatic therapy).
Dosage regimen
Application Somatulinom possible only in specialized institutions. The drug is administered only in / m.
Treatment starts with the introduction of trial (in the event of the ineffectiveness of further therapy is impractical) and evaluate response (the dynamics of growth hormone secretion of growth, symptoms, associated with carcinoid tumors).
The dosage regimen and duration of therapy is determined individually.
The drug is prescribed in / m at a dose 30 mg 1 once every 14 days. In inefficiency can increase the frequency of administration to 1 injection every 10 days.
Dissolution of freeze-dried product in the accompanying solvent should be performed immediately before injection by continuously shaking the vial until a homogeneous suspension of white or white with Valium a color shade. The suspension should not be mixed with other drugs.
Side effect
Local reactions: itch, burning, moderate transient pain at the injection site, sometimes accompanied by hyperemia.
From the digestive system: diarrhea or soft stool, celiac disease, abdominal pain, flatulence, nausea, vomiting; in rare cases, with prolonged use, may form gallstones (asymptomatic cholelithiasis).
Metabolism: rarely – increase in blood glucose level, change in glucose tolerance.
Contraindications
- Pregnancy;
- Lactation (breast-feeding);
- Hypersensitivity to the drug.
Pregnancy and lactation
The drug is contraindicated during pregnancy and lactation.
Patients, undergoing therapy Somatulinom, You should be aware of a possible violation of the reproductive function, as well as the appropriateness of the use of contraceptives during treatment and for Somatulinom 3 months after the end of treatment.
Cautions
In appointing Somatulinom patients with diabetes (as a type of 1, and such 2) should regularly monitor blood glucose levels and, if necessary, to adjust the dose of hypoglycemic drugs.
When carcinoid tumors of the gastrointestinal tract treatment Somatulinom appointed after the removal of the existing intestinal obstruction, tumor.
In the treatment of acromegaly, careful monitoring of the pituitary gland.
Prolonged treatment every 6 months should be performed ultrasound of the gallbladder.
If abnormal liver function or kidney disease should adjust the dose of the drug.
When concomitant administration with cyclosporine (orally), you need to adjust the dose of cyclosporine.
Overdose
Symptoms: may increase the side effects of the digestive system, electrolyte abnormalities.
Treatment: symptomatic therapy.
Drug Interactions
In an application with its enhanced insulin hypoglycemic effect, that require dose adjustment of insulin.
Conditions of supply of pharmacies
The drug is released under the prescription.
