Vigora is a medication that contains sildenafil citrate and is classified as a phosphodiesterase type 5 inhibitor. It is primarily prescribed to treat erectile dysfunction by improving blood flow to the penis. The drug works by blocking the enzyme phosphodiesterase type 5 which leads to increased cyclic guanosine monophosphate levels in smooth muscle cells. Higher cyclic guanosine monophosphate relaxes vascular smooth muscle allowing more blood to fill the erectile tissue. This physiological effect enables men to achieve and sustain an erection when sexual stimulation occurs. The active ingredient therefore enhances vascular response through targeted enzymatic inhibition resulting in improved erectile function.

Vigora is a medication that enhances erectile function by inhibiting phosphodiesterase type 5 in the corpus cavernosum. This inhibition leads to increased levels of cyclic guanosine monophosphate which relaxes smooth muscle and improves blood flow. The drug works by selectively targeting the enzyme responsible for breaking down cgmp in penile tissue. As a result it supports the natural physiological process of achieving and maintaining an erection. Its therapeutic effect is limited to improving sexual function and does not increase sexual desire. The mechanism relies on restoring the balance of vasodilatory signals within the penile vasculature.

Common side effects of Vigora may include headache dizziness and nausea. Some users report flushing of the skin and a warm sensation in the face. Visual disturbances such as blurred vision or sensitivity to light can occur. Muscle aches and back pain are also reported in certain cases. A feeling of heaviness or pressure in the chest may be experienced. Low blood pressure leading to lightheadedness can happen after dosing. Some individuals notice gastrointestinal discomfort such as indigestion or diarrhea. Fatigue and occasional dizziness may persist for a short period after taking the medication.
