Retabolil is an anabolic drug for systemic use.

Composition of 1 ml solution:
- Active ingredient: nandrolone decanoate - 50 mg;

Pharmacological properties
Pharmacodynamics
Nandrolone - the active component of Retabolil - a synthetic testosterone derivative. Possesses low androgenic activity.
Retabolil is a long-acting anabolic agent (depot drug). Promotes the stimulation of protein biosynthesis in the body, leads to a retention of calcium, nitrogen, potassium, sodium, chloride and phosphorus. As a result, there is an increase in muscle mass and acceleration of bone growth, and water retention in the body is observed.
Pharmacokinetics
Nandrolone decanoate is released slowly from the injection site into the bloodstream. T 1/2 (half-life) is 6 days. Ether in the blood is rapidly hydrolyzed to nandrolone with a T 1/2 of less than one hour. In general, T 1/2 for a process involving hydrolysis, distribution and elimination of the substance from the plasma is 4.3 hours.
Nandrolone metabolism occurs in the liver. The main metabolites - 19-norandosterone, 19-norepianthrosterone and 19-norethiocholanone, are excreted by the kidneys. There is no information on the pharmacological activity of these metabolites.
Indications for use
Retabolil is used to treat diseases in which prolonged use of anabolic drugs is indicated (in order to avoid complications, the drug can be taken strictly according to a medical prescription):
- Osteoporosis of various etiologies;
- Spinal amyotrophy of Werdnig-Hoffmann;
- Violation of protein metabolism associated with serious burns, trauma, surgery, radiation therapy, severe infectious diseases;
- Progressive muscular dystrophy;
- Cachexia of various etiologies;
- Diabetic retinopathy;
- Glomerulonephritis, programmed hemodialysis for chronic renal failure;
- Disseminated breast cancer in women (as a palliative therapy).
The combined use of Retabolil with glucocorticoids, cytostatic and tuberculostatic drugs is possible.
Contraindications
- Prostate and breast cancer in men;
- Nephrotic syndrome;

- heart failure;
- arterial hypertension;
- diabetes;
- severe atherosclerosis;
- violation of cerebral circulation;

- renal / hepatic impairment;
- hypertrophy of the prostate;
- history of glaucoma (anabolic steroids cause fluid and sodium retention in the body);
- epilepsy;
- convulsions (including a history);
- migraine;

The drug is prescribed for outpatient and inpatient treatment.
The doctor determines the dose of Retabolil individually.
The average adult single dose is 25-50 mg, for children - 0.4 mg / kg of body weight; frequency of administration - every 3-4 weeks.
With myopathies, individual doses may be prescribed. For cancer, the adult dose is 50 mg every 5 days; for severe renal failure, the same dose is administered weekly.
Side effects
Possible side reactions (in men and women): vomiting, nausea, loss of appetite, burning sensation in the tongue, decreased / increased libido, acne (especially in pubertal boys and women), sodium / nitrogen / water retention in the body, edema, jaundice, cholestasis, increased vascularization of the skin, suppression of gonadotropin secretion, hypercalcemia (especially in immobile patients and in women with metastases of breast cancer).
Also, depending on the sex of the patient, the following disorders may be observed:
- Women: symptoms of virilization (in the form of hirsutism, baldness, irreversible decrease in voice tone, clitoris enlargement, menstrual irregularities, suppression of ovarian function);
- Men: Frequent erections at puberty, suppression of testicular function, oligospermia, gynecomastia, enlarged penis.
Overdose
There is no data on overdose.
The main symptoms: increased side reactions.
Therapy: symptomatic. There is no specific antidote.
special instructions
To achieve the optimal therapeutic effect, during therapy, the patient should receive an adequate amount of minerals, vitamins, fats, proteins and carbohydrates with food.
Due to the androgenic activity, Retabolil can be prescribed to children and women only in cases where the intended benefit is higher than the possible risk.
The use of high doses of the drug at puberty can lead to premature closure of growth zones and growth arrest.
Retabolil can lead to the development of sodium and fluid retention in the body, therefore, it should be used with caution in arterial hypertension, renal / heart failure, epilepsy, migraine, glaucoma (as well as in the case of indications of these diseases in history). During the period of therapy, it is necessary to carefully monitor the intraocular pressure.
Before the appointment of Retabolil, as well as during treatment, it is necessary to carry out rectal control of the size of the prostate gland.
In some cases, during treatment, violations of the indicators of some functional liver tests are observed, and therefore, monitoring of liver function is indicated every month.
In diabetes mellitus, Retabolil can lead to an increase in glucose tolerance, thereby reducing the need for insulin / oral hypoglycemic drugs.
With metastases of breast cancer in the bone, hypercalcemia may develop. In these cases, the use of the drug is possible only after the normalization of the level of calcium in the blood.
The use of Retabolil to stimulate athletic qualities is unacceptable, as it can lead to serious impairments.
Application during pregnancy and lactation
Retabolil is not prescribed during pregnancy / lactation.
Pediatric use
Due to the androgenic activity of nandrolone, prescribing therapy for children is possible only if the expected benefit is higher than the potential risk. With the use of high doses of Retabolil at puberty, premature closure of growth zones and growth arrest are possible.
With impaired renal function
In case of renal failure, Retabolil is prescribed under medical supervision.
