Mechanism of Action
Inhibition of PDE5 Enzyme
Phosphodiesterase type 5 (PDE5) is an enzyme found in the smooth muscle cells of the penis. PDE5 breaks down cyclic guanosine monophosphate (cGMP), a molecule that promotes relaxation of blood vessels. By inhibiting PDE5, Tadalafil prevents the breakdown of cGMP, allowing it to accumulate in the penile tissues.
Relaxation of Blood Vessels
Increased cGMP levels relax the smooth muscles in the walls of blood vessels in the penis. This results in vasodilation, or the widening of blood vessels, which enhances blood flow.
Improved Erection
During sexual stimulation, the enhanced blood flow helps achieve and sustain an erection suitable for sexual activity. Without sexual stimulation, the medication will not cause an erection, ensuring it works in harmony with natural arousal.
Duration of Action: Actilis 20 mg provides an extended window of effectiveness, lasting up to 36 hours, allowing for more spontaneity in sexual activity.
Treatment of BPH: Actilis 20mg can also relax muscles in the prostate and bladder, alleviating symptoms of benign prostatic hyperplasia (BPH), such as difficulty urinating.
Long Half-Life: about 17.5 hours, which contributes to its prolonged duration of action compared to shorter-acting medications like sildenafil.
Consistent Results: The formulation of Actilis ensures reliable absorption and predictable effects.
Onset: Begins working within 30-60 minutes after ingestion. Sexual stimulation is required for it to be effective.
Duration: Effects last for up to 36 hours, allowing flexibility and spontaneity in planning sexual activity.
How It Supports Erectile Function
Actilis does not directly cause an erection. It enhances the natural process involved in achieving one during sexual stimulation. It addresses the most prevalent root cause of ED, which is insufficient blood flow to the penis.
