Tiagra Tablet 5 mg Introduction

Tiagra Tablet 5 mg is a drug used to treat male erectile dysfunction (ED) and benign prostatic hyperplasia (also known as benign enlargement of the prostate gland). It can also be used for pulmonary arterial hypertension (PAH). It is sold by many name brands including Adcirca, Cialis, and many others. It is an effective drug that can be taken as needed or daily, with the duration of effects lasting for up to 36 hours.

Uses for Tiagra Tablet 5 mg

Tiagra Tablet 5 mg is most commonly used to treat ED (erectile dysfunction), but it can also be used to treat the following conditions: benign enlargement of the prostate gland (benign prostatic hyperplasia), pulmonary arterial hypertension, and signs and symptoms of both benign prostatic hyperplasia and pulmonary arterial hypertension. In some cases, it can also be used to reduce high blood pressure.

Mechanism of Action

Tiagra Tablet 5 mg works by increasing blood flow to the penis and relaxing the smooth muscle of the corpus cavernosum, allowing the penis to become engorged with blood. This increased blood flow allows men to achieve and maintain an erection. In addition, tadalafil has been found to help reduce symptoms of benign prostatic hyperplasia and pulmonary arterial hypertension by blocking the enzyme phosphodiesterase (PDE5) and increasing levels of certain hormones, such as nitric oxide.
