pharmachologic effect

Tablets are used to treat dependence on nicotine. The active substance varenicline, when ingested, binds to α4β2 n-cholinergic receptors, in relation to which it is partially a nicotine agonist. Thus, simultaneous agonist activity (its degree is less than in nicotine) and antagonism in the presence of nicotine are noted.
Consequently, varenicline blocks the ability of nicotine to stimulate α4β2 n-cholinergic receptors and inhibits its activity with respect to the mesolimbic dopamine system. This mechanism is the basis for the formation of dependence on nicotine, that is, the pleasure derived from smoking.
Tablets from smoking Champix reduce craving for tobacco smoking, and significantly alleviate the symptoms of withdrawal syndrome. At the same time, the person taking this drug, gradually notes a decrease in the sense of pleasure from smoking.

After the drug was taken once (a dose of 0.1 mg to 3 mg) or after repeated administration or repeated administration of Champix in a similar dose, the linear character of the pharmacokinetics of varenicline was noted.
The active substance is distributed in the body tissues, penetrates the blood-brain barrier and enters the brain. There is a low degree of binding to blood plasma proteins - less than 20%.
About 92% in unchanged form is excreted from the body through the kidneys, less than 10% is excreted as metabolites. The half-life of varenicline is 24 hours.
