Revatio single dose volunteer studies of doses up to mg, adverse reactions were similar to those seen at lower doses, but the incidence rates and severities revatio increased. Pharmacodynamic effects Studies in vitro have shown that sildenafil is selective for PDE5. In the event of any sudden visual defect, the treatment should be stopped immediately and alternative treatment should be considered see section 4. Retinitis pigmentosa The safety of sildenafil has not been studied in patients with known hereditary degenerative retinal disorders such as retinitis pigmentosa a minority of these patients have genetic disorders of retinal phosphodiesterases and therefore its use is not recommended. In the two-placebo-controlled studies adverse events were generally mild to moderate in severity. Patients on sildenafil achieved a statistically significant reduction in mean Pulmonary Arterial Pressure mPAP compared to those on placebo. Patients on all sildenafil doses achieved a statistically significant reduction in mean pulmonary arterial pressure mPAP and pulmonary vascular resistance Revatio compared to those on placebo. The safety of sildenafil has not been studied in the following sub-groups of patients and its use is therefore contraindicated: Of the subjects who completed the initial study, entered a devatio extension study. Gevatio general, any dose adjustment should be administered only after a careful benefit-risk assessment. The co-administration of PDE5 inhibitors, including sildenafil, with guanylate cyclase stimulators, such as riociguat, is contraindicated as it may potentially lead to symptomatic hypotension see section 4.

Grapefruit juice is a weak inhibitor of CYP3A4 gut wall metabolism and may give rise to modest increases in plasma levels of sildenafil. Within each frequency grouping, adverse reactions are presented in revatio of decreasing seriousness. Efficacy in adult patients with PAH when used in combination with epoprostenol A randomised, double-blind, placebo controlled study was conducted in patients with PAH who were stabilised on intravenous epoprostenol. From the analysis of the pharmacokinetic profile of sildenafil in patients involved in the paediatric clinical trials, body weight was shown to be a good predictor of drug exposure in children.

Revatio is contraindicated in patients with severe hepatic impairment Child-Pugh class C see section 4. CYP3A4 inhibitors like clarithromycin, telithromycin and nefazodone are expected to have an effect in between that of ritonavir and CYP3A4 inhibitors like saquinavir or erythromycin, a seven-fold increase in exposure is assumed. Effects in non-clinical studies were observed at exposures considered sufficiently in excess of the maximum human exposure indicating little relevance to clinical use. The most revatio of the CYP3A4 inhibitors such as ketoconazole and itraconazole would be expected to have effects similar to ritonavir see section 4. By sildenafil treatment group, median duration of sildenafil treatment was days excluding the 5 subjects who received placebo in double-blind and were tablets treated in the long-term extension study. Due revatio lack of data on effects of Revatio in pregnant women, Revatio is not recommended for women of childbearing potential unless also using appropriate contraceptive measures.
