Male erectile dysfunction (ED) and pulmonary arterial hypertension (PAH) are treated with Vidalista 20 Tablet. It helps men achieve an erection by increasing blood flow to the penis. In PAH, it expands or relaxes the pulmonary blood vessels, lowering lung blood pressure. It is possible to take Vidalista 20 Tablet with or without food. It must be taken exactly as prescribed by your physician. Only when you are sexually stimulated will the ED medication help you achieve an erection. It is best to take it approximately one hour prior to your planned sexual activity. Although each person's working time is different, it typically takes 30 minutes or more.
