Novým blokátorem 5. izoenzymu fosfodiesterázy pro léčbu erektilní dysfunkce (ED) po sildenafilu a vardenafilu je tadalafil (Cialis). Jde o periferní kondicionér kavernózní svaloviny penisu, u nějž je ve studiích uváděna unikátní farmakokinetika. Lék je po perorálním podání absorbován relativně rychle, nástup účinnosti u většiny mužů je do 30 minut. Zajímavá je zejména doba účinnosti - až 36 hodin.

Lék je pacienty dobře tolerován, přerušení léčby pro nežádoucí účinky bylo zaznamenáno u 1,7% pacientů (placebo 1,1%). Kontraindikací je jako u sildenafilu kombinace s nitráty a donory NO2, a těžké, nestabilní kardiovaskulární onemocnění, které je samo o sobě rizikem při sexuální aktivitě. Poznatky získané při studiích s novým blokátorem PDE-5 posouvají významným způsobem kupředu léčbu sexuálních dysfunkcí.

TADALAFIL (CIALISTM) - A NEW INHIBITOR OF PDE-5 IN THERAPY OF ERECTILE DYSFUNCTION

Tadalafil (Cialis), following sildanefil and vardenafil, is a new blocker of the 5th isoenzyme of phoshodiesterase (PDE-5) and is used for the treatment of erectile dysfunction. It is a peripheral conditioner of the cavernous muscles of the penis and is characterized, according to reported studies, by unique pharmacokinetics. The drug, which is absorbed relatively quickly after oral use, has a pharmacological efficacy within 30 minutes in the majority of men. This efficacy time is very interestingly, 36 hours. The drug is very well tolerated, with only 1.7 % of patients (placebo 1.1%) discontinuing use due to side effects. As in sildanefil, the contraindications are combination therapy with nitrates and nitric oxide donors, and severe forms of unstable cardiovascular disease, which, by themselves, represent a high risk during sexual activity. The knowledge obtained from the studies with the new PDE-5 blocker contributes significantly to the therapy options for sexual dysfunction.
