Vigora 100 mg belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. It works by relaxing the blood vessels in the penis, allowing more blood to flow into the area when a man is sexually aroused. However, certain lifestyle factors can influence how well the medication works. For instance, poor blood circulation, stress, and unhealthy habits like smoking or excessive alcohol consumption can dampen its effects. Making changes in these areas can optimize your body’s response to the medication, leading to better and more consistent results.
