Vidalista 20 is a medication used to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). Tadalafil belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors, which work by increasing blood flow to the penis or lungs, depending on the condition being treated.In the case of ED, tadalafil helps to relax the blood vessels in the penis, allowing for increased blood flow and thus, an erection. Tadalafil does not cause an erection on its own and requires sexual stimulation to work.For PAH, tadalafil helps to relax the blood vessels in the lungs, allowing for improved blood flow and a reduction in symptoms such as shortness of breath and dizziness.Tadalafil is available in tablet form and is typically taken orally, either as needed for ED or once daily for PAH, as prescribed by a healthcare provider. It is important to follow the dosing instructions provided by a healthcare provider and not to exceed the recommended dose. <!--td {border: 1px solid #cccccc;}br {mso-data-placement:same-cell;}-->For More Medzvilla helps you.
