Kamagra Gold 100 mg is marketed as a treatment for erectile dysfunction (ED) and is commonly associated with sildenafil 100 mg. Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor that works by increasing blood flow to the penis during sexual stimulation, helping some men achieve and maintain an erection. Sildenafil does not increase sexual desire and does not normally cause an erection without sexual stimulation. For ED, the appropriate dose depends on factors such as age, health conditions, other medicines, and individual response.
