X 100 Soft Gelatin Capsule contains Sildenafil 100 mg, a potent selective phosphodiesterase type 5 (PDE5) inhibitor indicated for the treatment of erectile dysfunction (ED) in adult males. Sildenafil facilitates penile erection by enhancing the effects of nitric oxide, a natural chemical released during sexual stimulation, which increases cyclic guanosine monophosphate (cGMP) levels and promotes smooth muscle relaxation in the corpus cavernosum, resulting in improved blood flow. This medication should be taken approximately 30 to 60 minutes before anticipated sexual activity, with its effects lasting up to four hours. It is important to note that sexual stimulation is required for the drug to be effective. X 100 Soft Gelatin Capsule is contraindicated in patients using nitrates or nitric oxide donors due to the risk of severe hypotension. Caution is advised in patients 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 priapism should seek immediate medical attention. This product should be used under medical supervision to ensure safety and efficacy.
