One medication used to treat erectile dysfunction is Vidalista 5mg. It belongs to the pharmacological class of phosphodiesterase type 5 inhibitors. Because nitric oxide activates the enzyme guanylate cyclase, which increases the amounts of cyclic guanosine monophosphate, the smooth muscles in the penis relax. This relaxation causes blood to flow into the penile arteries, which leads to an erection. Vidalista 5mg generally functions well for men between the ages of 18 and 64. Your treatment won’t cost too much because it’s a generic brand. This helps men maintain and achieve an erection. It belongs to the group of medications known as phosphodiesterase type 5 inhibitors.
