Advancing Effective Research Policy
[1][4][67][116][131] Sildenafil and its major circulating N-desmethyl metabolite are each approximately 96% bound to plasma proteins; protein binding reportedly is independent of plasma concentration. [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).
Insurance Information
[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. [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. In Malaysia, Viagra is available primarily in 50 mg and 100 mg dosages, both widely acknowledged for their efficacy in boosting men's confidence in intimate settings.
Sildenafil is a medication used to treat erectile dysfunction in men. It works by increasing blood flow to the penis during arousal. Sildenafil is commonly sold under the brand name Viagra. The typical dose ranges from 25 mg to 100 mg, taken before sexual activity. It usually takes about 30 to 60 minutes to work after ingestion. Sildenafil's effects can last for up to 4-6 hours. It can cause side effects like headaches, flushing, and nasal congestion. Sildenafil should not be used with nitrate medications due to risk of dangerous drops in blood pressure. It is available by prescription from a healthcare provider. Do not take sildenafil more than once a day to avoid adverse effects.
