How Sildenafil Citrate Works: Pharmacological Mechanism
Cenforce Soft 100 mg is a phosphodiesterase-5 (PDE5) inhibitor. PDE5 is an enzyme (a protein that drives chemical reactions in the body) found in the smooth muscle tissue of penile blood vessels.
Nitric oxide is released by the body during sexual stimulation. This triggers cGMP production. cGMP relaxes blood vessel walls. Blood then flows into the penile tissue.
Sildenafil Citrate inhibits PDE5. This action prevents cGMP from breaking down. This sustains vasodilation (widening of blood vessels) and supports a natural erectile response during stimulation.
Cenforce Soft 100 has no effect on sexual desire. Sexual stimulation must be present for it to work. It supports the body’s natural physiological response. It does not bypass it.
Clinical Uses and Indications
Cenforce Soft 100 is indicated for erectile dysfunction (ED) in adult males. ED is clinically defined as the persistent inability to achieve or maintain an erection firm enough for satisfactory sexual activity.
It is prescribed for ED arising from vascular (blood vessel-related), psychological, or combined causes. This medicine has no antibacterial, antifungal, or antiviral properties. It does not treat infections or hormonal conditions.
Symptoms It Helps Address:
- Difficulty achieving an erection during sexual stimulation
- Insufficient erection firmness for intercourse
- Inability to maintain an erection throughout sexual activity
Any treatment must be medically supervised. Completion of any scheduled dosing programme is essential where your clinician has prescribed structured therapy.
Doses and Administration
Take Cenforce Soft 100 orally. Let it dissolve in the mouth. Alternatively, chew it as directed. Water is not required unless your doctor specifically advises it.
It should be taken 30 to 45 minutes before planned sexual activity. Only take this medicine when sexual activity is planned. Do not take it daily unless your prescriber has specifically advised this.
Within any 24-hour period, one dose is the maximum permitted. High-fat meals before use may slow absorption. Avoid them where possible.
If your clinician has provided a scheduled treatment plan, complete the full prescribed course as directed.
