Sildenafil, Tadalafil, and Vardenafil Tablets are medications used primarily for the treatment of erectile dysfunction (ED), a condition where men experience difficulty achieving or maintaining an erection. These drugs belong to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors, which work by blocking the enzyme PDE5, leading to increased blood flow to the penis during sexual arousal.
1. Sildenafil (Viagra)
Sildenafil is one of the most well-known medications for ED. It is typically taken about 30 to 60 minutes before sexual activity and can remain effective for up to 4-6 hours. Sildenafil works by enhancing the effects of nitric oxide, a chemical that relaxes the muscles of the penis, allowing increased blood flow. It is usually taken on an as-needed basis, and its effects are generally limited to a single sexual session.
Common side effects of Sildenafil include headaches, facial flushing, indigestion, and visual disturbances.
2. Tadalafil (Cialis)
Tadalafil is unique because of its longer duration of action, which can last up to 36 hours, earning it the nickname "The Weekend Pill." It can be taken as needed before sexual activity or in a lower, daily dose for continuous effect. Tadalafil helps relax the muscles in the blood vessels, improving blood flow to the penis. It is also sometimes prescribed for symptoms of benign prostatic hyperplasia (BPH), a condition in which the prostate is enlarged.
Common side effects of Tadalafil include headaches, back pain, muscle aches, and indigestion.
3. Vardenafil (Levitra)
Vardenafil is similar to Sildenafil in its mechanism of action but is often regarded as being more potent for some individuals. It is typically taken 25-60 minutes before sexual activity and lasts for about 4-5 hours. Vardenafil helps increase blood flow to the penis by inhibiting the PDE5 enzyme. It is effective for many men, particularly those who may not respond well to Sildenafil.
Common side effects of Vardenafil include headaches, nasal congestion, facial flushing, and dizziness.
