Introduction:
The discontinuation rate with phosphodiesterase type 5 inhibitors (PDE5i) remains very high. Recently, a new PDE5ì, avanafil, has become available worldwide.
Areas Covered:
All placebo-controlled randomized clinical trials (RCTs) on the effect of avanafil in patients with ED were reviewed and meta-analyzed. So far, 5 different RCTs on avanafil have been published, including 1379 and 605 patients in active and placebo groups, respectively. Avanafil was up to 3-fold superior to placebo in determining successful sexual intercourse. Although head-to-head comparative studies are still lacking, re-analyses of available data, showed that avanafil had comparable efficacy, but lower incidence of drug-related side effects, compared to first-generation PDE5is.
Expert Opinion:
Avanafil specific and peculiar pharmacological profile, addresses several problems that have been documented with first-generation PDE5is. Avanafil should theoretically guarantee a low dropout incidence by ensuring a natural profile of action and a low incidence of side effects. Longer studies and head-to-heard trials are advisable to clarify these issues.

This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

01:16Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
