Suhagra is a generic medication containing sildenafil citrate, prescribed for the treatment of erectile dysfunction (ED). As a phosphodiesterase type 5 (PDE5) inhibitor, its mechanism of action involves enhancing blood flow to the penis during sexual stimulation. It achieves this by inhibiting the enzyme responsible for breaking down cGMP, a substance that relaxes smooth muscle and allows for increased blood flow. Sexual arousal is a necessary prerequisite for the medication to be effective. Suhagra is typically taken 30 to 60 minutes before sexual activity, and its effects last for approximately 4 to 6 hours. Common side effects include headache, facial flushing, and indigestion. It is absolutely contraindicated for patients taking any form of nitrate medication, as their combined use can lead to a severe and life-threatening drop in blood pressure. A thorough medical evaluation is required to ensure it is a safe and appropriate treatment.
