Still pretending everything's fine?

[1][67][91][116][131] Sildenafil is distributed to a limited extent in semen following oral administration, with less than 0.001% of a single dose appearing in semen 90 minutes after dosing in healthy individuals. [1][67] Such concentrations are unlikely to cause any effects in sexual partners exposed to the semen. [67] Plasma sildenafil concentrations appear to decline in a biphasic manner following oral administration, with a terminal elimination half-life of about 4 hours (range: 3-5 hours). [1][4][67][91][116][127][130][131] Sildenafil is metabolized principally via hepatic cytochrome P-450 (CYP) microsomal isoenzymes 3A4 (major route) and 2C9 (minor route). [1][26][67][91][131] Plasma concentrations of the active N-desmethyl metabolite are approximately 40% of those observed with sildenafil, and the metabolite reportedly accounts for about 20% of sildenafil's pharmacologic activity.

Patient resources

[1][67][131] The N-demethylated metabolite, the major circulating metabolite, has a phosphodiesterase selectivity profile similar to that of sildenafil and an in vitro potency for PDE type 5 of approximately 50% of the parent drug. [1][116][131] Sildenafil is eliminated mainly in the feces as metabolites following oral administration. [1][67][91][116][131] In healthy adults and those with ED, approximately 80% of an oral dose is excreted as metabolites in feces and 13% is excreted in urine. Importance of instructing patients to read the manufacturer's patient information before starting sildenafil therapy and each time their prescription is refilled. [1]Instruct patients to avoid contraindicated medications such as regular and/or intermittent use of organic nitrates, organic nitrites (e.g., ''poppers''), and riociguat. Suffer from severe heart or liver problems. Have recently had a stroke or heart attack Have a rare inherited eye disease called retinitis pigmentosa Have ever suffered a loss of vision due to non-arteritic ischaemic optic neuropathy.
