Cenforce 200 is a highly effective black pill for men's health that contains sildenafil citrate. This particular brand, Cenforce 200 mg, contains the active ingredient sildenafil. The mechanism of action of sildenafil involves the dilation and relaxation of blood vessels in the penile area, resulting in increased blood flow. This ultimately helps in achieving and maintaining an erection. It is recommended to take Cenforce 200 three times a day, with a minimum interval of four to six hours between doses. Cenforce belongs to the class of PDE 5 inhibitors, which are also used for the treatment of pulmonary hypertension. However, the dosage for erectile dysfunction may vary from that of pulmonary hypertension.
