viagra works by increasing blood flow to the penis, which is essential for achieving and maintaining an erection. it does this by blocking a specific enzyme called phosphodiesterase type 5, or PDE5, which is responsible for breaking down a chemical called cyclic guanosine monophosphate, or cGMP. when cGMP is not broken down, it causes the smooth muscles in the penis to relax, allowing blood to flow more freely and resulting in an erection.
what are the typical dosage recommendations?
the typical dosage recommendations for sildenafil citrate, the active ingredient in viagra, are as follows: a daily dose of 50mg is often considered the starting point for many patients, although the dosage may be adjusted based on the individual response to the medication. most patients find that a dose of 50mg is adequate for achieving and maintaining an adequate erection for most sexual activities.
what are the potential side effects of viagra?
like any medication, viagra can have side effects, although most are mild and transient. common side effects include facial flushing, headache, feeling bloated or膨胧, upset stomach, and runny or frequent urination. these side effects usually resolve within a few hours after taking the medication. in rare cases, longer-lasting side effects such as blue-tinted vision, priapism, or other complications may occur.
