Vidalista 80 mg is a medication primarily used to treat erectile dysfunction (ED) in men. It contains the active ingredient Tadalafil, which enhances blood flow to the penis, facilitating an erection when sexually stimulated. The drug works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), allowing for increased levels of cyclic guanosine monophosphate (cGMP) and prolonged vasodilation. The effects of Vidalista can last up to 36 hours, providing a larger window for sexual activity compared to other ED medications. Common side effects include headache, flushing, nasal congestion, and upset stomach. It is essential to consult a healthcare provider before using Vidalista.
