Pharmacological properties

vasodilating and antispasmodic. It has a hypotensive, vasodilating effect, stimulates the function of the spinal cord, and has moderate immunostimulating activity.

It has a direct antispasmodic effect on the smooth muscles of blood vessels and internal organs. The drug causes a short (2-3 hours) and moderate hypotensive effect, well tolerated. It causes a short expansion of the cerebral vessels in chronic cerebral hypoxia caused by local circulatory disorders (cerebral artery sclerosis). Facilitates synaptic transmission in the spinal cord. It has immunomodulatory activity. By regulating the ratio of cGMP and cAMP concentrations in immune cells, it increases the cGMP content, which leads to the proliferation of mature sensitized T- and B-lymphocytes, their secretion of mutual regulation factors, a cooperative reaction, and activation of the final effector function of cells. The drug stimulates the production of antibodies, enhances the phagocytic activity of leukocytes, macrophages, improves the synthesis of interferon, but the immunomodulating effect develops slowly.

Pharmacokinetics With the / m introduction, the drug quickly penetrates into the systemic circulation. Cmax in the blood is reached after 15-30 minutes from the time of administration. The duration of action is 2-3 hours. It is metabolized in the liver.

The biotransformation products of dibazole are two conjugates resulting from the methylation and carboethoxylation of the imino group of the imidazole ring of dibazole: 1-methyl-2-benzylbenzimidazole and 1-carboethoxy-2-benzylbenzimidazole.

Metabolism products are excreted mainly in the urine.

Quickly absorbed in the digestive tract. The therapeutic effect occurs 30-60 minutes after taking the drug. The duration of action is 2-3 hours. The drug is excreted mainly in urine.

Indications

As an additional tool for blood vessel spasms (exacerbations of ag, hypertensive crises) and smooth muscles of internal organs (spasms of the pylorus of the stomach, intestines); in the treatment of nervous diseases (mainly the residual effects of poliomyelitis, peripheral facial paralysis, polyneuritis).

Side effects

From the nervous system: dizziness, headache;

cardiac disorders: palpitations, pain in the heart, with prolonged use - deterioration of ECG in connection with a decrease in cardiac output; decrease in blood pressure;

special instructions

Before starting treatment, you should consult your doctor!

Dibazole in the form of injections is an auxiliary agent that is used in hypertension, provided that it is sensitive to other antihypertensive drugs. In the treatment of hypertension, it is recommended to combine with other antihypertensive drugs.

Long-term use of Dibazol-Darnitsa as an antihypertensive agent in elderly patients is not advisable due to the possibility of ECG deterioration and cardiac output reduction.

It is not recommended for prolonged treatment of hypertension, especially in elderly patients.

The drug contains a small amount of ethanol (alcohol), less than 100 mg / dose.

Use during pregnancy and lactation. Do not use the drug during pregnancy and lactation.

Children. The drug should not be prescribed to children under the age of 12 years.

The ability to influence the reaction rate when driving vehicles or working with other mechanisms. During treatment, care should be taken when driving vehicles and working with complex mechanisms, and in case of dizziness, refrain from engaging in potentially dangerous activities that require an increased concentration of attention and speed of psychomotor reactions.

Interactions

If the patient is taking any other medicines, you should definitely consult with your doctor about the possibility of using the drug.

Papaverine hydrochloride, theobromine, salsolin - when combined with dibazole, the pharmacological action of papaverine hydrochloride, theobromine, salsolin is expanding.

Barbiturates - when combined with dibazole, the effectiveness of long-acting barbiturates increases, in particular phenobarbital.

Phentolamine, antihypertensive drugs (agents that affect the renin-angiotensin system), saluretics - when combined with dibazole, the antihypertensive effect increases.

Β-adrenergic receptor blockers - when combined with dibazole, the hypotensive effect of the latter does not change, but with prolonged use, dibazole prevents the increase in OPSS caused by β-adrenergic receptor blockers.

Overdose

Symptoms: arterial hypotension, increased sweating, sensation of fever, dizziness, nausea, mild headache, which quickly pass when the drug is discontinued.

Treatment. Cancel the drug. With severe arterial hypotension under the control of blood pressure, transfusion therapy, vasoconstrictors, cardiac glycosides are prescribed. Further treatment is symptomatic.
