Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. You should not use VIAGRA with any other oral or local treatments for erectile dysfunction. See comparison of erectile dysfunction tablets for further information.

Sildenafil helps relax the blood vessels at the base of your penis, improving blood flow and helping you get harder erections when you’re aroused. VIAGRA 100MG tablets contain sildenafil, a medication used to treat erectile dysfunction (ED) in men. Sildenafil works by increasing blood flow to the penis, helping to achieve and maintain an erection when sexually aroused. Sildenafil can be taken every day, up to the recommended maximum dosage of 100mg. It helps men with erectile dysfunction enjoy more adventure and freedom – because it is a highly-effective and minimally-disruptive medication that can get to work in less than an hour. Viagra is a prescription-only medication that is used to treat erectile dysfunction (ED) in men, and works for around 74% of men who try it.

The major circulating metabolite results from N-demethylation of sildenafil. This metabolite has a phosphodiesterase selectivity profile similar to sildenafil and an in vitro potency for PDE5 approximately 50% that of the parent drug. Plasma concentrations of this metabolite are approximately 40% of those seen for sildenafil. The N-desmethyl metabolite is further metabolised, with a terminal half-life of approximately 4 h. When sildenafil is taken with food, the rate of absorption is reduced with a mean delay in tmax of 60 minutes and a mean reduction in Cmax of 29%. In cases of overdose, standard supportive measures should be adopted as required.

If this occurs, it’s usually within 1–2 hours after taking it. When PDE5 inhibitors like Viagra are used to treat erectile dysfunction, these medications work by widening the blood vessels, thus, increasing blood flow into the penis. Notably, the effects of Viagra only occur in the presence of sexual stimulation.

In several clinical studies, Viagra was effective in treating ED. In these studies, males who used the drug had an improved ability to have and keep erections that helped them have sex.

Consider a starting dose of 25 mg in patients treated with strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, or saquinavir) or erythromycin. Clinical data have shown that co-administration with saquinavir or erythromycin increased plasma levels of sildenafil by about 3 fold [see Drug Interactions (7.4) and Clinical Pharmacology (12.3)]. Population pharmacokinetic analysis of clinical trial data indicated a reduction in sildenafil clearance when co-administered with CYP3A4 inhibitors (such as ketoconazole, erythromycin, cimetidine). Although no increased incidence of adverse events was observed in these patients, when sildenafil is administered concomitantly with CYP3A4 inhibitors, a starting dose of 25 mg should be considered. Most, but not all, of these patients had pre-existing cardiovascular risk factors.

Sildenafil (Viagra) has a half-life of 4 hours and vardenafil (Levitra 40 mg) has a half-life of 4-6 hours while tadalafil (Cialis) has a half-life of 17.5 hours. This means that vardenafil (Levitra) should act longer than sildenafil (Viagra) but the clinical significance is not known. Tadalafil (Cialis) has the longest half-life and allows you to take the medication and not relate the sexual activity to the immediate use of the medication.

The physiologic mechanism of erection of the penis involves release of nitric oxide (NO) in the corpus cavernosum during sexual stimulation.
