Sildenafil citrate, the same active ingredient in Silditop 100 used for ED, is also used to treat pulmonary arterial hypertension (PAH). In PAH, sildenafil works by relaxing the blood vessels in the lungs, leading to improved exercise capacity and reduced symptoms such as shortness of breath. Silditop 100 is primarily prescribed for ED, its pharmacological properties and vasodilatory effects have led to exploration in various other health areas. However, it's crucial to use sildenafil and medications like Silditop 100 under medical supervision and as prescribed, considering potential interactions, side effects, and individual health considerations.
