Cyclic vilitra 20 mg tablet price in india guanosine monophosphate (cGMP) plays a crucial role in achieving an erection because it increases vasodilation of the p*nile muscles, increasing blood flow. However, PDE-5 is an enzyme that is known to break down cGMP and cause a weak erection.  buy vilitra 40 mg (the active ingredient in Vilitra) stops the activity of the PDE-5 enzyme by mimicking cGMP. It is structurally so similar to cGMP that the enzyme PDE-5 binds to vardenafil instead of cGMP. An increase in the cGMP concentration in the vilitra 60 mg online blood will increase blood circulation to the p*nis and help you get/maintain a firm erection during s*xual intercourse. However, it is important to know that cGMP is only activated when NO (nitric oxide) is released in the corpus cavernosum, the Super Vilitra erectile tissue of the p*nis. And NO is only released in response to sufficient s*xual stimulation. Therefore, Vilitra 20 mg will not work in the absence of s*xual stimulation. If you plan to take it occasionally, depending on your needs, it is recommended to take a Vilitra 10 pill half an hour to an hour before having s*x. If you are taking it on the recommendation of your doctor, take the medication as directed (usually 1 pill per day). Do not take more than the recommended dose, ie one tablet Sildalist 120 per day, unless otherwise directed by your doctor. You should avoid taking the pill more than four hours before having s*x because its potency starts to drop after that. Also, you can take it with or without food, but the latter is better as aurogra 100 dosage works faster without food.
