Tadalafil is one of the dual compounds found in Megalis tablets. Tadalafil blocks blood circulation, which is necessary for a penile erection and for sexual activity, by acting on the PDE5 enzyme in the penile region. A firm penile erection for penetrative intercourse is provided by the chemical, which also increases blood circulation in the penile region and inhibits the enzyme. It is classified as an SSRI, or selective serotonin reuptake inhibitor. It is an antidepressant that helps men postpone ejaculation so they may engage in sexual activity with a woman for a longer period of time and experience the physical delights of the encounter. Men can engage in sexual activity without worrying about erectile dysfunction or early ejaculation by taking the pill.
