Zenegra 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. Here are some key points about Zenegra 100 mg:
Mechanism of Action: Zenegra 100 mg works by inhibiting the enzyme PDE5 in the smooth muscle cells of the penis. This action leads to increased levels of cyclic guanosine monophosphate (cGMP), which helps relax the blood vessels and improve blood flow to the penis during sexual stimulation. As a result, men can achieve and maintain an erection suitable for sexual activity.
Dosage and Administration: Zenegra 100 mg is available in tablet form and is taken orally with a full glass of water. The recommended starting dosage for most men with ED is 50 milligrams, taken as needed approximately 30 minutes to 1 hour before sexual activity. Depending on individual response and tolerability, the dosage may be increased to 100 milligrams or reduced to 25 milligrams.
Onset of Action: Zenegra 100 mg typically starts to work within 30 to 60 minutes after ingestion, although individual response times may vary. It's important to note that sexual arousal or stimulation is necessary for the medication to be effective.
Duration of Action: The effects of Zenegra 100 mg can last for approximately 4 to 6 hours after ingestion. During this time, men may experience improved erectile function and the ability to engage in satisfactory sexual activity.
Effectiveness: Zenegra 100 mg has been shown to be effective in treating ED in various clinical studies. It contains sildenafil citrate, which is the same active ingredient found in Viagra and other sildenafil-based medications known for their efficacy in improving erectile function.  |
