Mechanism of Action: How Sildenafil Works
Sildenafil Citrate belongs to a therapeutic class called phosphodiesterase-5 (PDE5) inhibitors (enzymes that contract blood vessels). These enzymes regulate vascular tone and blood flow.
The pharmacological process works through targeted enzyme inhibition:
- Enzyme Blockade: Sildenafil binds to and blocks PDE5, an enzyme in the body.
- Vessel Relaxation: This action increases cyclic guanosine monophosphate (cGMP) levels. Blood vessels within the penile tissue undergo relaxation, an effect caused by this chemical.
- Increased Blood Flow: Relaxed vessels allow blood to flow more freely into the area when required.
Important Clinical Fact
Sildenafil Citrate does not cause spontaneous erections. External sexual stimulation is strictly necessary to trigger the natural chemical release required for the medicine to work.
Safety Information and Adverse Reactions
All medicines containing PDE5 inhibitors carry potential side effects. Patients in the UK should report any suspected adverse reactions using the official MHRA Yellow Card scheme.
