PDE5 inhibitors, also known as phosphodiesterase 5 inhibitors, are drugs that are commonly used to prevent the breakdown of cGMP (cyclic guanosine monophosphate) in the smooth muscle cells lining the blood arteries supplying the penis’ primary erectile tissues.

PDE5 5 inhibitors relax smooth muscles, maintaining normal penile function. For the treatment of erectile dysfunction (ED), PDE5 inhibitor drugs including Vardenafil Levitra, Tadalafil (Vitalitey 50 Mg), and Sildenafil are recommended. In addition, they manage several additional male sexual concerns, like premature ejaculation for use Cenforce 200 mg.

PDE5 inhibitors have a proven track record of success in treating and managing erectile dysfunction, making them the drug of choice in this regard.

Where is PDE5 located?

A large range of PDE5 enzymes degrade cGMP. These PDE5 enzymes are widely dispersed throughout the body and are involved in multiple tissue functions.

For example, PDE 5 enzymes are present in platelets, kidneys, lungs, pancreatic, cerebellar, vascular, and visceral smooth muscle, as well as in the smooth muscle of the corpus cavernosum.

Can ED Be Treated With PDE5 Inhibitors?

PDE5 inhibitor drugs stop the breakdown of cGMP, which opens up the penile region’s blood vessels and increases the duration of vasodilator mediators such as nitric oxide. Nitric oxide release triggers the synthesis of cGMP, which is required for a penile erection.

The primary erectile tissue, the corpus cavernosum, contains smooth muscle that triggers the penile erection process. During sexual stimulation, the corpus cavernosum nerve ending releases nitric oxide.

When Should I Start Taking PDE5?

PDE5 inhibitors include drugs for male pulmonary arterial hypertension, benign prostatic hyperplasia, and erectile dysfunction.

One of the most common sexual problems among men is erectile dysfunction. The disease prevents men from achieving or maintaining a penile erection long enough to partake in fulfilling sexual activity. There are several problems that might impact the different components of erectile function and lead to impaired function.

Pulmonary arterial hypertension is the term used to describe high blood pressure in the arteries that supply the lungs. When the pulmonary arterial pressure exceeds 25 mm Hg, pulmonary arterial hypertension is suggested.

Benign prostatic hyperplasia is a common problem among males by the age of fifty.

What is the best PDE5 inhibitor?


Viagra is the brand name under which sildenafil is sold. According to clinical trials, the oral dosage of sildenafil is anticipated to begin acting in 30 minutes and to peak in an hour.

However, the serum half-life of this medicine is four hours. Moreover, taking a dose of this medication shortly after consuming a fatty meal reduces the efficiency of sildenafil because it is a lipophilic molecule.

Here are a few additional Viagra alternatives, including Cenforce 100mg.


Adcirca and Cialis are two brand names under which tadalafil is sold. The over-the-counter drug Cialis is one of the best therapies for erectile dysfunction and benign prostatic hyperplasia. Adcirca is one medication that is marketed to treat pulmonary arterial hypertension.

Tadalafil has been shown to begin to act as early as 16 minutes in. Furthermore, Tadalafil’s efficiency is unaffected by taking this medicine either before or directly after a fatty meal.


Vardenafil is marketed under the following three brands: Levitra, Staxyn, and Vivanza. This drug is recommended as a treatment for erectile dysfunction.

Vardenafil should be taken 30 to 1 hour before engaging in sexual activity. Additionally, specialists recommend taking the medication one to two hours before or after meals because doing so may affect the drug’s effectiveness. It takes five to seven hours for this drug to start working.
