Product Overview

Tadalafil PAH is an FDA-approved medication containing the active ingredient Tadalafil. It is a phosphodiesterase type 5 inhibitor commonly marketed under the brand name Adcirca. It is used for the treatment of pulmonary arterial hypertension (PAH), which is a kind of high blood pressure in the arteries of the lungs. It works by settling the blood vessels in the lungs to improve blood flow, thereby decreasing the stress on the heart and improving exercise capacity in those with PAH.

Tadalafil PAH is typically available in tablet form with strength: Tadalafil 20mg. The recommended dose is usually 40 mg once daily, with or without food. It’s crucial to follow the dosage prescribed by a healthcare professional, as dosage may vary based on individual factors such as age, weight, and severity of the condition. 

Common side effects of Tadalafil PAH may include headache, flushing, stomach upset, back pain, and muscle pain. In some cases, more severe side effects, like sudden vision or hearing loss, may occur. You should seek medical attention if you experience any severe side effects.

You should not miss doses, as it may reduce the effectiveness of the medication. If so, take the missed dose unless it is almost time for the next one. It should not be taken more than once daily to prevent the risk of overdose. It should be stored at room temperature, away from moisture, heat, children, and pets. You should discuss the usage guidelines with a healthcare professional to ensure safe use.

How Does Tadalafil PAH Work?

Tadalafil PAH works by relaxing the blood vessels in the lungs, decreasing stress on your heart. Tadalafil is a kind of phosphodiesterase type 5 (PDE5) inhibitor. By inhibiting PDE5, Tadalafil increases levels of cyclic guanosine monophosphate (cGMP), which is a type of chemical that helps to dilate blood vessels. This dilation improves blood flow in the lungs, alleviating symptoms of pulmonary arterial hypertension (PAH) and reducing the workload on the heart.
