Tadalafil 20 mg Tablet: Overview
Tadalafil is a well-known prescription medication primarily used to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). It is marketed under notable brand names, including Cialis and Adcirca. Tadalafil operates by increasing blood flow to specific areas of the body, facilitating the achievement and maintenance of an erection, while also assisting in lowering blood pressure within the lungs.
What is Tadalafil Used For?
Tadalafil 20 mg tablet is commonly prescribed for the following conditions:
- Erectile Dysfunction (ED): Tadalafil is effective for men who have challenges in achieving or sustaining an erection during sexual activities.
- Pulmonary Arterial Hypertension (PAH): It aids in improving exercise capability and delaying clinical deterioration in patients suffering from high blood pressure in the pulmonary arteries.
- Benign Prostatic Hyperplasia (BPH): Tadalafil can help alleviate symptoms associated with an enlarged prostate, such as difficulty urinating and increased frequency.
How Does Tadalafil Work?
Tadalafil works by inhibiting an enzyme called phosphodiesterase type 5 (PDE5). By blocking this enzyme, Tadalafil enhances the effects of nitric oxide, a critical component for achieving erections. This mechanism relaxes the muscles in blood vessels, leading to increased blood flow to the penis during sexual arousal. Additionally, it dilates blood vessels in the lungs, thereby reducing pulmonary blood pressure.
