What is Avanafil Powder?

Avanafil powder is the powder form of the ED drug Avanafil, it is used to treat men who have erectile dysfunction (also called sexual impotence). Avanafil belongs to a group of medicines called phosphodiesterase 5 (PDE5) inhibitors. These medicines prevent an enzyme called phosphodiesterase type-5 from working too quickly. The penis is one of the areas where this enzyme works.

Erectile dysfunction is a condition where the penis does not harden and expand when a man is sexually excited, or when he cannot keep an erection. When a man is sexually stimulated, his body’s normal response is to increase blood flow to his penis to produce an erection. By controlling the enzyme, avanafil helps to maintain an erection after the penis is stroked by increasing blood flow to the penis. Without physical action to the penis, such as that occurring during sexual intercourse, avanafil will not work to cause an erection.

There are the different forms of Avanafil including powder form, tablet, and capsule. etc. Avanafil powder is the base ingredient used to make oral Avanafil tablets or pills. Avanafil’s brand name is Stendra, it has 50mg, 100mg, and 200mg.

How does Avanafil powder work?

Raw Avanafil powder for sale in the market, inhibits the cGMP-specific phosphodiesterase type 5 (PDE5) which is responsible for the degradation of cGMP in the corpus cavernosum located around the penis. Sexual arousal results in the local release of nitric oxide, which in turn stimulates the enzyme guanylate cyclase to produce cGMP. Elevated levels of cGMP result in local smooth muscle relaxation and increased blood flow to the penis (i.e. an erection).

As PDE5 inhibitors like avanafil require the endogenous release of nitric oxide in order to exert their pharmacologic effect, they have no effect on the user in the absence of sexual stimulation/arousal.

What is Avanafil powder use for?

Avanafil powder for sale is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, avanafil works by increasing blood flow to the penis to help a man get and keep an erection. This drug does not protect against sexually transmitted diseases (such as HIV, hepatitis B, gonorrhea, and syphilis). To decrease your risk of infection, always use an effective barrier method (latex or polyurethane condom/dental dams) during all sexual activity. 

How to use Avanafil Pills?

Avanafil Vs Sildenafil: Which one is stronger?

The brand name of Avanafil powder is Stendra, and the brand name of Sildenafil citrate is Viagra. they all both medications used to treat ED. Avanafil Vs Sildenafil, which one is stronger? Let’s see the frequently asked questions about Avanafil and Sildenafil:

  Is Avanafil work faster than Sildenafil?

Yes, one of the biggest advantages of Avanafil is that it works quickly, often in as little as 15 minutes after consumption. Viagra and generic medications containing sildenafil, on the other hand, typically take action in about one hour. This means that you’ll need to take the medication slightly earlier than Avanafil (Stendra) for it to be effective by the time you plan to have sex.

 Is Avanafil last longer than Sildenafil?

Yes, Avanafil has a slightly longer half-life than Sildenafil, meaning one tablet of it will generally provide relief from erectile dysfunction for longer than an equivalent dose of Sildenafil.

How long does Avanafil last? Avanafil powder, the active ingredient in Stendra, has a terminal half-life of around five hours, meaning it takes five hours to reach 50 percent of its original concentration in your body.

Sildenafil, the active ingredient in Viagra, has a half-life of four hours.

Cialis(tadalafil) is a long-lasting medication for ED. In fact, it’s often referred to as the “weekend pill” due to its 17.5-hour half-life, which allows a single dose to provide  relief from erectile dysfunction for as long as 36 hours.

③ Does Avanafil is better than Sildenafil for ED treatment?

Clinical studies of avanafil (the active ingredient in Stendra) and sildenafil (the active ingredient in Viagra) show that both medications are very effective at treating erectile dysfunction for most men.

④ Avanafil has fewer side effects than Sildenafil?

Yes, both Avanafil and Sildenafil have the potential to cause drug interactions when they’re taken with other medications and substances. Avanafil and Sildenafil can both cause similar side effects. However, study data show that fewer men experience several common side effects, such as headaches and nasal congestion, with Avanafil than with Sildenafil.

⑤ Avanafil is safer than Sildenafil?

Avanafil and Sildenafil are both safe medications, provided they’re used as prescribed. If you’re a healthy male with no history of cardiovascular disease, kidney disease, high blood pressure, or other health issues, you can safely use either drug as prescribed by your doctor.

⑥ Avanafil is cheaper than Sildenafil?

No. Because the active ingredient in Viagra Sildenafil powder is now available as a generic medication (sildenafil), it’s a significantly more affordable option than Avanafil. From a value-for-money perspective, generic sildenafil is the most affordable option for treating erectile dysfunction. It contains the exact same active ingredient as Viagra and works the same way within your body, making it a comparatively cost-effective ED treatment option.

So Avanafil Vs Sildenafil in summary:

-Stendra and Viagra are both medications for treating erectile dysfunction. Both belong to a class of medications called PDE5 inhibitors, which work by increasing blood flow to the erectile tissue inside your penis.

-Both medications can be taken before sex. Viagra typically starts working in 30 minutes to one hour, whereas Stendra is a faster-acting medication that can begin working in 15 to 30 minutes.

-Although both medications work by increasing blood flow to your penis, Stendra is more selective in its effects. This means that it’s slightly less likely to cause some side effects than Viagra.

-Contrary to popular belief, neither Stendra nor Viagra causes random erections or affects your sex drive. Both medications only cause erections when you have a form of sexual stimulation, such as sexual activity or a sexual thought.

-As an older medication, Viagra is now available as a generic, making it more affordable than Stendra. The generic name for Viagra is sildenafil. Because Stendra is so new, it’s unlikely that a generic version will be made available in the next few years.

What is HNMR and What does HNMR spectrum tell you? H Nuclear Magnetic Resonance (NMR) spectroscopy is an analytical chemistry technique used in quality control and research for determining the content and purity of a sample as well as its molecular structure. For example, NMR can quantitatively analyze mixtures containing known compounds. For unknown compounds, NMR can either be used to match against spectral libraries or to infer the basic structure directly. Once the basic structure is known, NMR can be used to determine molecular conformation in solution as well as studying physical properties at the molecular level such as conformational exchange, phase changes, solubility, and diffusion.
