Filitra is a medication designed to assist men with erectile dysfunction (ED) by enhancing blood flow to the penis. Filitra active ingredient, vardenafil, is a phosphodiesterase type 5 (PDE5) inhibitor. During sexual arousal, nitric oxide is released, leading to the production of cyclic guanosine monophosphate (cGMP). cGMP relaxes the smooth muscles in the penis, allowing increased blood flow and facilitating an erection. PDE5 breaks down cGMP, but vardenafil inhibits this enzyme, thereby prolonging the effects of cGMP and maintaining the erection.

Filitra typically starts working within 30 to 60 minutes and remains effective for up to 4 to 6 hours. It is important to note that sexual stimulation is required for the medication to be effective . The medication is available in various dosages, including 10 mg, 20 mg, and 40 mg, allowing for tailored treatment based on individual needs.

Common side effects may include headache, dizziness, and nasal congestion. Men with certain health conditions, such as heart disease or those taking nitrates, should consult a healthcare provider before using Filitra .
