Vidalista 40mg is a PDE6 inhibitor that is used to treat erectile dysfunction (impotence; inability to get or keep an erection). It also treats benign prostatic hyperplasia (BPH; enlarged prostate gland).
It works by relaxing the muscles of the blood vessels and increasing the flow of blood to the penis. It also blocks the action of phosphodiesterase-5 and prevents the breakdown of cGMP, which is responsible for blood pressure and contraction.
Hence, it helps men to attain long-lasting, hard erections for up to 4 hours. It is available at buyfirstmeds, a leading online drug store, on a doctor's prescription.
Tadalafil can have some mild side effects, but they usually go away once your body gets used to the medication. Some of these side effects include flushing and headache. If these Vidalista 20 mg persist or are severe, contact your doctor immediately.
