Pharmacological properties

Pharmacodynamics

Dinatrop is one of the genetically engineered somatotropic hormones that stimulate somatic / skeletal growth, and also have a pronounced effect on metabolic processes. Stimulation of the growth of bones of the skeleton occurs due to the effect on bone metabolism and the lamina of the pineal gland of tubular bones. The normalization of body structure occurs through a decrease in fat and an increase in muscle mass. With a deficiency of growth hormone and osteoporosis, replacement therapy with Dinatrop leads to the normalization of bone density and mineral composition. The therapy allows you to increase the size and number of cells of the adrenal glands, thyroid gland, liver, muscles, sex glands, thymus gland.

Somatropin stimulates the transport of amino acids into the cell and protein synthesis and, by influencing the lipoprotein / lipid profile, reduces cholesterol levels. Promotes the retention of phosphorus, sodium, potassium. Suppresses insulin release. Increases muscle activity, physical endurance and weight.

Pharmacokinetics

Absorption of somatropin after subcutaneous administration is 80%, the maximum plasma concentration in the blood (C _max) is reached after 3–6 hours. Penetrates into well-perfused organs. Somatropin is metabolized in the liver and kidneys. It is excreted in the bile and kidneys (including 0.1% unchanged). The half-life (T _1/2) after a single dose is in the range from 3 to 5 hours.

Indications for use

Growth hormone Dinatrop is prescribed to children with growth retardation associated with the following diseases / conditions:

• dysgenesis of the gonads (Shereshevsky-Turner syndrome);
• insufficient secretion of growth hormone;
• chronic renal failure (with a decrease in renal function by more than 50%) in the prepubertal period.

For adults, Dinatrop is prescribed as substitution therapy for confirmed acquired / congenital growth hormone deficiency.

Contraindications

Absolute:

• active brain tumors;
• urgent conditions, including the state of acute respiratory failure and after operations on the abdominal cavity and heart;
• malignant neoplasms;
• pregnancy and the period of breastfeeding;
• established individual intolerance to the components of the drug.

Relative (diseases / conditions in which the use of Dinatrop requires caution and medical supervision):

• diabetes;
• hypothyroidism;
• intracranial hypertension.

Instructions for the use of Dinatrop: method and dosage

The method of administration of Dinatrop is subcutaneously, slowly.

Frequency rate of application - 1 time per day (usually at night). In order to prevent the development of lipoatrophy, it is necessary to change the injection sites.

The dose is determined by the doctor individually, and the severity of growth hormone deficiency, weight / body surface area, and the effectiveness of the therapy should be taken into account.

Recommended daily doses:

• insufficient secretion of growth hormone in children: 0.025–0.035 mg / kg (0.7–1 mg / m ²). Therapy should be started as early as possible. It continues until puberty / until the bone growth zones are closed, and the cancellation of Dinatrop is possible after the desired result is achieved;
• Shereshevsky-Turner syndrome, chronic renal failure in children, accompanied by growth retardation: 0.05 mg / kg (1.4 mg / m ²); in cases of insufficient growth dynamics, the dose is adjusted;
• growth hormone deficiency in adults: 0.15-0.3 mg, depending on the effectiveness of therapy, the dose is increased. When performing dose titration, the serum level of insulin-like growth factor I can be used as a control parameter. The maintenance dose is selected individually; it usually does not exceed 1 mg per day. For elderly patients, Dinatrop is usually prescribed in lower doses.

It is recommended to dissolve the lyophilisate (based on the prescribed dose) in 1 ml of the supplied solvent. After the introduction of the solvent, the vial should be gently shaken until the contents are completely dissolved, avoiding sudden shaking.

Side effects

Possible side reactions: increased intracranial pressure (occurs with headache, nausea, vomiting, visual impairment), tunnel syndrome, decreased thyroid function, myalgia, arthralgia, leukemoid reactions, hyperglycemia, epiphyseolysis of the femoral head, fluid retention with the development of peripheral edema. These disorders are usually transient, dose-dependent, which may lead to the need for dose reduction.

Allergic reactions can manifest as itching and skin rashes.

In rare cases, the formation of antibodies to Dinatrop is noted, which leads to a decrease in the effectiveness of therapy.

The most likely local reactions: swelling, hyperemia, itching, pain, lipoatrophy at the injection site.

There is also information about the development of the following adverse reactions when using the drug Somatropin: weakness, gynecomastia, subluxation of the hip in children (limping, knee / hip pain), fatigue, pancreatitis (nausea, abdominal pain, vomiting), edema of the optic nerve head (usually, observed during the first 2 months of therapy, in most cases with Shereshevsky-Turner syndrome), otitis media and hearing impairment (with Shereshevsky-Turner syndrome), progression of scoliosis (with excessively rapid growth), accelerated growth of a pre-existing nevus, an increase in inorganic phosphate in the blood, the activity of alkaline phosphatase and parathyroid hormone.

Overdose

In acute overdose, hypoglycemia may develop first, then hyperglycemia.

The main symptoms of prolonged overdose: acromegaly / gigantism, hypothyroidism, a decrease in serum cortisol levels in the blood.

Therapy: cancellation of Dinatrop, symptomatic treatment.

special instructions

In patients with diabetes mellitus, during the use of Dinatrop, a dose adjustment of hypoglycemic drugs may be required.

Possible manifestation of latent hypothyroidism. Patients receiving thyroxine may show signs of hyperthyroidism.

During the period of therapy, the state of the fundus should be monitored, especially when symptoms of intracranial hypertension appear. In cases of development of optic nerve edema, Dinatrop is canceled.

If lameness is detected, the condition of the patients should be carefully monitored.

Application during pregnancy and lactation

Growth hormone Dinatrop is contraindicated during pregnancy and breastfeeding.

Use in the elderly

For elderly patients, Dinatrop should be administered in lower doses.
