Sildamax 100 Mg, containing sildenafil citrate as its active ingredient, functions by inhibiting the enzyme phosphodiesterase type 5 (PDE5), thereby promoting the dilation of blood vessels in the penis and facilitating increased blood flow, which aids in achieving and maintaining an erection. The standard dosage is typically 50-100 mg, to be taken approximately 30-60 minutes before sexual activity. This dosage is determined based on factors such as age, health status, and the severity of ED. Adhering to these guidelines is essential for safety and efficacy.
