What is Sildenafil: how does it work, side effects, dosages, and more!
Sildenafil is one of the most widely used medications for treating erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). Originally developed to improve blood flow to the heart, it was later found to have a powerful effect on increasing blood flow to the penis, making it effective for ED treatment. It works by relaxing muscles and arteries in specific areas of the body, allowing for increased circulation. Today, Sildenafil is available in both brand-name and generic versions, with flexible dosage options, and is used by millions of men around the world to support sexual performance and cardiovascular health.
