Vilitra 10 contains Vardenafil as its active ingredient, and it works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). Here's how Vilitra 10 helps maintain an erection:

Inhibition of PDE5: When a man is sexually aroused, nitric oxide is released in the erectile tissue of the penis. This nitric oxide activates an enzyme called guanylate cyclase, which leads to increased levels of cyclic guanosine monophosphate (cGMP).

Relaxation of Blood Vessels: Elevated cGMP levels cause the smooth muscles in the blood vessels of the penis to relax, allowing for increased blood flow into the penis. This increased blood flow is essential for achieving and maintaining an erection.

Enhanced Erectile Response: PDE5 is responsible for breaking down cGMP, thus reducing its levels and causing the smooth muscles in the blood vessels to contract again. By inhibiting PDE5, Vilitra 10mg helps maintain higher levels of cGMP, prolonging the relaxation of the blood vessels and enhancing the erectile response.

Duration of Action: Vilitra 10 has a duration of action that allows it to remain effective for several hours after ingestion. This extended period of effectiveness gives men a longer window of opportunity for sexual activity without the need to take another dose.

Usage Instructions: Vilitra 10 should be taken orally, typically about 25 to 60 minutes before anticipated sexual activity. It can be taken with or without food, but high-fat meals may delay the onset of action. Sexual stimulation is necessary for the medication to work effectively.

Safety and Side Effects: Like all medications, Vilitra 10 may cause side effects in some individuals, such as headache, flushing, indigestion, nasal congestion, and dizziness. Serious side effects are rare but should be reported to a healthcare provider if experienced.
