buy vidalista 20mg is an effective drug for treating male sexual problems like Erectile Dysfunction (ED) and Benign Prostatic Hyperplasia (BPH). It inhibits PDE-5 enzyme that degrades cyclic guanosine monophosphate levels in the blood vessels. It also releases nitric oxide and enhances cGMPs to widen those vessels for easier flow of blood.
It is taken 30 to 60 minutes before any sexual intercourse and helps to generate a hard erection that lasts for around 4 to 6 hours. It can be taken with or without food but the best results are obtained when consumed on an empty stomach.
The drug must not be used in patients who have heart problems or are taking nitrate drugs for heart conditions, as it may cause a sudden decrease in blood pressure. It is also contraindicated in men who are advised to avoid sexual activity due to medical reasons.
