100 ml of syrup contains:
- active substance: butamirate citrate - 0.15 g;

Pharmacological properties
Pharmacodynamics
Butamirate is a centrally acting antitussive drug. Its active substance, butamirate, has a direct effect on the cough center, which causes the suppression of cough. Shows a bronchodilating effect, promotes the expansion of the bronchi, improves spirometry indicators (lowering airway resistance) and oxygenation of the blood (blood oxygenation), and facilitates breathing.
Butamirate neither chemically nor pharmacologically refers to the alkaloids of opium, does not cause the formation of dependence and addiction.
Pharmacokinetics
After oral administration, butamirate is rapidly and completely absorbed in the gastrointestinal tract. While taking doses of 22.5; 45; Its measured concentrations of 67.5 and 90 mg are determined in the blood after 5-10 minutes. The maximum concentration (C max) in the blood plasma is achieved within 1 hour, when a dose of 90 mg is taken orally, it averages 16.1 ng / ml.
The effect of food on the absorption of butamirate has not been established.
The available data suggest that butamirate ester is rapidly and completely absorbed and hydrolyzed in plasma to form 2-phenylbutyric acid and diethylaminoethoxyethanol.
The mean plasma concentration of 2-phenylbutyric acid is achieved within 1.5 hours and dietilaminoetoksietanola -. 0.67 hours after administration of the drug at a dose of 90 mg C max of 2-phenylbutyric acid was 3052 ng / ml, dietilaminoetoksietanola - 160 ng / ml.
In the dose range from 22.5 to 90 mg, the level of 2-phenylbutyric acid and diethylaminoethoxyethanol changes in proportion to the size of the dose taken.
The volume of distribution is from 81 to 112 liters.
Plasma protein binding of 2-phenylbutyric acid is 89.3-91.6%, diethylaminoethoxyethanol - 28.8-45.7%.
The penetration of butamirate through the placenta and its excretion in breast milk has not been studied.
Butamirate is metabolized very quickly as a result of hydrolysis with the formation of 2-phenylbutyric acid and diethylaminoethoxyethanol, which have an antitussive effect. By hydroxylation in the para-position, 2-phenylbutyric acid undergoes further partial metabolism. After conjugation in the liver, acidic metabolites are largely bound to glucuronic acid.
Excretion of metabolites occurs mainly through the kidneys. Conjugates of 2-phenylbutyric acid in urine are determined in higher concentrations than in blood plasma. In urine, butamirate is detected within 48 hours. After taking the drug at a dose of 22.5; 45; 67.5 and 90 mg, when sampling for 96 hours, the share of butamirate excreted in urine is approximately 0.02; 0.02; 0.03 and 0.03% of the dose taken, respectively.
In percentage terms, diethylaminoethoxyethanol is excreted in the urine in a larger amount, compared with the excretion of unconjugated 2-phenylbutyric acid or butamirate in unchanged form.
The half-life (T 1/2) of butamirate is 1.48-1.93 hours, 2-phenylbutyric acid is 23.26-24.42 hours, diethylaminoethoxyethanol is 2.27-2.9 hours.
