The best use of sildenafil tablets is for the treatment of erectile dysfunction (ED) in men. Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor that works by increasing blood flow to the penis during sexual stimulation, enabling an erection. It is most effective when taken about 30 minutes to 1 hour before sexual activity and can remain effective for up to 4-6 hours. Sildenafil tablets are also used to treat pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries of the lungs. However, the dosage and administration for PAH differ from that of ED, and it's essential to consult a healthcare professional for proper guidance and dosage adjustments. you should try fildena super active
