Sildenafil Medication Description
Sildenafil is a prescription medication used to treat erectile dysfunction (ED) by increasing blood flow to the penis, helping to achieve and maintain an erection during sexual activity. It works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which enhances the effects of nitric oxide, a natural chemical the body produces to relax muscles in the penis and improve circulation. Sexual stimulation is required for sildenafil to be effective.
Sildenafil is available in various strengths, with dosing tailored to age, tolerance, and response. It is typically taken before anticipated sexual activity but not more than once in a 24-hour period.
