Fildena CT 100 is primarily used to treat erectile dysfunction (ED), not premature ejaculation (PE). It contains sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor, which works by increasing blood flow to the penis to help achieve and maintain an erection during sexual stimulation. While some men with ED and PE might notice improved performance due to increased confidence and sustained erection, Fildena CT 100 mg does not directly affect the ejaculation process. PE involves early ejaculation, which is typically treated with medications like selective serotonin reuptake inhibitors (SSRIs), behavioral therapy, or topical anesthetics. Therefore, Fildena CT 100 is not a direct or approved treatment for premature ejaculation.
