BigFun 100 is a prescription drug used to treat adult male erectile dysfunction (ED). The phosphodiesterase type 5 (PDE5) inhibitor sildenafil citrate, which is 100 mg in each tablet, increases blood flow to the ***** during sexual stimulation, making it easier to get and keep an erection.
BigFun, which is made by Leeford Healthcare Ltd., is also used to treat pulmonary arterial hypertension (PAH) by promoting blood flow by relaxing the lungs' blood arteries.
