Tadalafil is a medication belonging to a group of drugs called phosphodiesterase-5 (PDE5) inhibitors. It works by relaxing blood vessels in the penis, increasing blood flow and allowing for an erection.
Here’s a breakdown of its mechanism:
- Sexual Stimulation: The process begins with sexual stimulation, triggering the release of nitric oxide (NO). NO’s Role: NO activates an enzyme called guanylate cyclase, which increases levels of cyclic guanosine monophosphate (cGMP). CGMP’s Action: Increased cGMP relaxes the smooth muscles in the blood vessels of the penis. Tadalafil’s Function: Tadalafil inhibits PDE5, an enzyme that breaks down cGMP. By inhibiting PDE5, tadalafil prolongs the effects of cGMP, maintaining relaxation of the blood vessels and facilitating an erection.
Remember, Tadalafil only works in the presence of sexual stimulation. It doesn’t cause spontaneous erections.
The duration of action for Tadalafil is longer than that of some other PDE5 inhibitors. This means the effects can last up to 36 hours, allowing for flexibility in timing of sexual activity. However, individual responses may vary.
Consult your doctor before using Tadalafil. Discuss any potential side effects or drug interactions. Follow your doctor’s prescribed dosage carefully.
