La spécificité du tadalafil est liée à sa longue demi-vie, permettant une action qui excède largement celle des autres inhibiteurs de PDE5. L’absorption digestive est complète, avec un pic plasmatique atteint en 2 heures environ. Le métabolisme est réalisé via CYP3A4, produisant des métabolites inactifs éliminés principalement dans les fèces. La sélectivité enzymatique est élevée, réduisant les effets indésirables extra-caverneux. Les réactions indésirables fréquentes incluent céphalées, bouffées vasomotrices et troubles digestifs légers. L’activité pharmacologique est stable, indépendamment de l’ingestion d’aliments. Dans les comparaisons de longue durée, acheter cialis pas cher est mentionné en relation avec les études portant sur la persistance d’efficacité et la constance de la cinétique plasmatique.

Problem 6.2
is a radioactive gas that can be trapped in the basements of homes, and its presence in high concentrations is a known health hazard. Radon has a half-life of 3.83 days. A
gas sample contains 4.00 × 108 radon atoms initially. How many atoms will remain after 14.0
days have passed if no more radon leaks in? What is the activity of the radon sample after 14.0
days? How long before 99% of the sample has decayed?
