What sildenafil used for? Sildenafil is primarily used to treat erectile dysfunction (ED) in men, a condition where achieving or maintaining an erection becomes difficult. By increasing blood flow to the penis, sildenafil helps facilitate erections during sexual stimulation. It works by inhibiting an enzyme called phosphodiesterase type 5 (PDE5), which relaxes blood vessels and improves circulation. In addition to treating ED, sildenafil is also used to manage pulmonary arterial hypertension (PAH), a condition where high blood pressure affects the arteries in the lungs, improving the ability to exercise and overall quality of life. https://www.dosepharmacy.com/fildena-100mg-tablet
