Megalis 10 mg is a medication used to treat erectile dysfunction (ED) in men. It contains Tadalafil, which is also known by the brand name Cialis. As a phosphodiesterase type 5 (PDE5) inhibitor, it helps improve blood flow to the penis by affecting the cGMP cycle, which controls blood vessel activity.
Megalis 10 mg helps men who have trouble getting or keeping an erection, which can be caused by both physical and psychological factors.
An erection happens when blood fills the penis. This occurs as blood vessels widen to let more blood in and narrow to keep the blood from flowing out. When a man is sexually aroused, nitric oxide is released in the penis, triggering the production of cGMP. This chemical controls how blood vessels expand and contract, allowing a firm erection to occur.
