1. What Is Vardenafil hydrochloride raw powder?

Vardenafil hydrochloride also known by the brand name Levitra, is a prescription medication that treats male erectile dysfunction.


Erectile dysfunction is when a man is unable to get or sustain an erection. It usually happens because the arteries that carry the blood to the penis are too narrow.

Vardenafil hydrochloride increases blood flow to the penis.

Its action is similar to that of sildenafil, or Viagra, but Viagra lasts between 2 and 4 hours, while Levitra lasts 4 hours.

2. How Does Vardenafil hydrochloride raw powder Works?

Vardenafil hydrochloride can help a man get and maintain an erection.

During a penile erection, the penis fills with blood.


The blood vessels that supply the penis with blood expand, or dilate, and the vessels that take blood away from the penis contract. The two large chambers in the penis, known as the corpus cavernosa, fill with blood.


As the blood accumulates in the penis, an erection results.

Vardenafil hydrochloride belongs to a class of drugs called phosphodiesterase type-5 (PDE5) inhibitors. A PDE5 inhibitor stops PDE5 from constricting the arteries.By relaxing the arteries, vardenafil hydrochloride enhances blood flow when a man is sexually aroused.

The active ingredient works on the chain of reactions within the penis during arousal.


When a male is sexually aroused, nitric oxide is released into his penis, and this triggers a chain of reactions.This causes an enzyme, guanylate cyclase, to produce cyclic guanosine monophosphate (cGMP).cGMP regulates the contraction and dilation, or expansion, of blood vessels that carry blood to and from the penis. 


The chemical reaction causes the vessels that supply the penis to dilate, while those removing blood from the penis contract.Phosphodiesterase-5 (PDE5), another enzyme breaks down or destroys cGMP.When cGMP is destroyed, the blood vessels return to their normal size, effectively ending the erection. Vardenafil hydrochloride stops PDE5 from destroying cGMP. In this way, it allows cGMP to work for longer. As a result, it helps prolong an erection.


Mechanism Of Action

Penile erection is a hemodynamic process initiated by the relaxation of smooth muscle in the corpus cavernosum and its associated arterioles. During sexual stimulation, nitric oxide is released from nerve endings and endothelial cells in the corpus cavernosum. Nitric oxide activates the enzyme guanylate cyclase resulting in increased synthesis of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the corpus cavernosum. The cGMP in turn triggers smooth muscle relaxation, allowing increased blood flow into the penis, resulting in erection. The tissue concentration of cGMP is regulated by both the rates of synthesis and degradation via phosphodiesterases (PDEs). The most abundant PDE in the human corpus cavernosum is the cGMP-specific phosphodiesterase type 5 (PDE5); therefore, the inhibition of PDE5 enhances erectile function by increasing the amount of cGMP. Because sexual stimulation is required to initiate the local release of nitric oxide, the inhibition of PDE5 has no effect in the absence of sexual stimulation.





3. How to Use Vardenafil hydrochloride raw powder?

Vardenafil hydrochloride may be taken with or without food.But do not drink large amounts of alcohol before sexual activity. Because alcohol can make it more difficult to get an erection,Moderate amounts of alcohol (2 drinks for a 70 kg person) will not interfere with the medication.

² Nitrates are found in medications that are used to treat angina (chest pain). If you are not sure if you are taking nitrates, ask your doctor or pharmacist before taking it. Nitrates must NOT be taken by anyone who is using Vardenafil hydrochloride because they can cause your blood pressure to drop very low. This may cause dizziness, fainting, heart attack, or stroke.
