Vidalista 10 is commonly used to increase blood flow and help men sustain their erections. Tadalafil can be used to treat erectile dysfunction by inhibiting phosphodiesterase type 5 specifically for cyclic guanosine monophosphate. Because phosphodiesterase type 5 is blocked in the corpus cavernosum, it enhances the effects of nitric oxide by limiting smooth muscle relaxation and blood flow to the area. This process is caused by a breakdown in cGMP. This medicine can be used with or without food. Flushing, headaches, dizziness, blurred vision, abdominal pain, rash, and an upset stomach are the most common side effects of this medicine.
