Sildenafil is a medication primarily used to treat erectile dysfunction (ED) in men. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Sildenafil works by increasing blood flow to the penis, which helps to achieve and maintain an erection during sexual stimulation.

In addition to treating ED, sildenafil is also prescribed to treat pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries of the lungs. By relaxing the blood vessels in the lungs, sildenafil helps to improve exercise capacity and delay disease progression in individuals with PAH.

It is important to note that sildenafil should only be used under the guidance of a healthcare professional. They will evaluate your medical history, assess any potential risks or contraindications, and determine the appropriate dosage for your specific needs. It is crucial to follow the prescribed instructions and not exceed the recommended dose to ensure safety and effectiveness.
