Grace Drugs & Pharmaceuticals Sildenafil 50mg Tablet contains sildenafil citrate, a selective phosphodiesterase type 5 (PDE5) inhibitor indicated for the treatment of erectile dysfunction (ED) in adult males. By inhibiting PDE5, sildenafil enhances the effects of nitric oxide released during sexual stimulation, resulting in increased blood flow to the corpus cavernosum and facilitating the achievement and maintenance of an erection. This medication is intended for use only under medical supervision and should be taken approximately 30 to 60 minutes before sexual activity, with its effects lasting up to 4-5 hours. The recommended dose is 50mg, which may be adjusted based on efficacy and tolerability, not exceeding one dose per day. Sildenafil is contraindicated in patients using nitrates or nitric oxide donors due to the risk of severe hypotension. Caution is advised in individuals with cardiovascular disease, hepatic or renal impairment, and those taking other medications that may interact with sildenafil. Common adverse effects include headache, flushing, dyspepsia, nasal congestion, and dizziness. Patients experiencing sudden vision loss, hearing impairment, or prolonged erections lasting more than 4 hours should seek immediate medical attention. Grace Drugs & Pharmaceuticals Sildenafil 50mg Tablet should be stored in a cool, dry place away from direct sunlight and out of reach of children.
