About Viagra.

One of the most popular and trusted medications Viagra belongs to amazing medical breakthroughs of the last 15 years.
Viagra is prescribed to millions of males worldwide because it is a safe and well tolerated medication with high efficacy showing best results in treating erectile dysfunction in men.
Viagra is an oral therapy for treating mild, moderate and severe erectile dysfunction in men caused by different factors. Viagra tablets are formulated as blue, film-coated, diamond-shaped pills in doses of 25 mg, 50 mg, and 100 mg of sildenafil citrate.
Viagra’s main component is the citrate salt of sildenafil, this crystalline powder belongs to the drug class of selective inhibitors of cyclic guanosine monophosphate or cGMP, in other words specific phosphodiesterase type 5 (PDE5).
Sildenafil citrate inhibits PDE type 5, enhancing the effect of nitric oxide (a natural substance necessary for normal erection process) and thus allowing increased levels of cyclic guanosine monophosphate. Cyclic GMP produces smooth muscle relaxation in the corpus cavernosum and providing extra blood inflow into the penis. Sexual stimulation is necessary to get Viagra start working. Sildenafil has no effect in the absence of sexual stimulation.
Clinical studies have shown high efficacy of Viagra and if taken in recommended doses the drug is usually well tolerated.
Viagra is quickly absorbed and distributed in the human body, with max plasma levels between 30 and 120 minutes after oral administration. This means the drug should be taken when needed, 30 minutes to 1 hour before sexual activity. The effect of the drug will last for 4 hours that is why you may take it up to 4 hours before sexual activity.
Viagra is excreted as metabolites mainly in the feces and to a lesser extent in the urine.
