Men with erectile dysfunction (ED) and pulmonary arterial hypertension (PAH) can be treated with the medication Vidalista 20. Tadalafil is the active component in it. A PDE5 inhibitor called Vidalista 20mg causes the penis’ blood vessels to relax, which facilitates easier blood flow into the penis during sexual stimulation and leads to an erection. It’s crucial that you follow your doctor’s instructions if you’re prescribed Vidalista 20. Never take more than the dosage that is advised. Please contact your physician if you have any side effects or have any concerns about taking this medication. One tablet of Vidalista pills should be taken orally, with water, on an empty stomach, or both.
