Viagra can decrease blood flow to the optic nerve of the eye, causing sudden vision loss. This has occurred in a small number of people taking sildenafil, most of whom also had heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoked or were over 55 years old. It is not clear whether sildenafil is the actual cause of vision loss.

Spraying the hormone up his nose twice a day did little to help his  social phobia but did wonders for his love life, the Journal of Sexual Medicine reports.

But oxytocin, the so-called  ‘cuddle hormone’, can dramatically improve male sexual performance, researchers have found – producing results on a par with Viagra.

Studies have produced relevant data on the effects of VIAGRA on cardiac output. In one small, open-label, uncontrolled, pilot study, eight patients with stable ischemic heart disease underwent Swan-Ganz catheterization. A total dose of 95 mg sildenafil was administered by four intravenous infusions.

After either oral or intravenous administration, sildenafil is excreted as metabolites predominantly in the feces (approximately 85% of administered oral dose) and to a lesser extent in the urine (approximately 68% of the administered oral dose). Similar values for pharmacokinetic parameters were seen in normal volunteers and in the patient population, using a population pharmacokinetic approach.

Sildenafil enhances the effect of NO by inhibiting phosphodiesterase type 5 (PDE5), which is responsible for degradation of cGMP in the corpus cavernosum. Sildenafil has no direct relaxant effect on isolated human corpus cavernosum. When sexual stimulation causes local release of NO, inhibition of PDE5 by sildenafil causes increased levels of cGMP in the corpus cavernosum, resulting in smooth muscle relaxation and inflow of blood to the corpus cavernosum. Sildenafil at recommended doses has no effect in the absence of sexual stimulation.
