Distribution. The average Vss of Vega Extra 120 is 105 l. the Association of Extra Vega and its main circulating N-demethyl metabolite with plasma proteins is about 96% and does not depend on the total concentration of the drug. Less than 0.0002% of the dose of Vega Extra Cobra 120 (an average of 188 ng) was found in sperm 90 minutes after taking the drug.

The main circulating active metabolite, formed as a result of N-demethylation of Vega Extra 120, undergoes further metabolism. The selectivity of this metabolite against PDE is comparable to that of Vegab Extra, and its activity against PDE-5 in vitro is about 50% of the activity of Vega Extra 120.

N-demethyl metabolite undergoes further metabolism; its T1/2 is about 4 no.

The efficacy of the drug was evaluated globally using an erection diary, an international erectile function index (validated questionnaire on the state of sexual function) and a partner survey.

The effectiveness of Signature Cobra Vega, defined as the ability to achieve and maintain an erection sufficient for satisfactory sexual intercourse, has been demonstrated in all studies and confirmed in long-term studies lasting 1 year.
