Filitra 20 mg, containing the active ingredient vardenafil, is a medication used to treat erectile dysfunction (ED) in men. The onset time of Filitra 20 mg varies among individuals but generally begins within 30 to 60 minutes after oral ingestion. This timeframe is consistent with other vardenafil formulations, including the 10 and 40 mg doses .
The medication works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which leads to increased blood flow to the penis during sexual arousal. It's important to note that sexual stimulation is necessary for Filitra 20 mg to be effective; the drug does not induce an erection without arousal .
While the onset of action is typically within an hour, individual factors such as age, overall health, and the presence of other medical conditions can influence how quickly the medication takes effect. Additionally, taking Filitra 20 mg on an empty stomach may lead to faster absorption and onset compared to taking it with a heavy meal .  |
