Description
Product Description
Megalis 20mg Tablet belongs to the phosphodiesterase type-5 (PDE5) inhibitor group. Tadalafil helps improve penile blood flow when a man is sexually stimulated, making an erection easier to achieve and maintain.
The medicine does not increase sexual desire and does not produce an erection without sexual stimulation. Because Tadalafil has a relatively long duration of action, its effects can extend well beyond the time of administration. The 20 mg strength should be used according to the individual treatment plan prescribed by the doctor.
Uses
- Treatment of erectile dysfunction in adult men.

- May also be prescribed for benign prostatic hyperplasia (BPH) symptoms when considered appropriate by a doctor.

How It Works
Tadalafil inhibits phosphodiesterase type-5, an enzyme that breaks down cyclic GMP in penile tissue. During sexual stimulation, nitric oxide signalling increases cyclic GMP, which relaxes smooth muscle and allows greater blood flow into the penis. By slowing cyclic GMP breakdown, Tadalafil supports this natural erectile response. It does not directly create sexual arousal and cannot produce an erection without sexual stimulation.
