Everything You Need to Know About PDE5 Inhibitors

Phosphodiesterase 5 inhibitors (PDE5 inhibitors) are medications that are extensively used to prevent the breakdown of cGMP (cyclic guanosine monophosphate) in smooth muscle cells lining blood arteries supplying the penis’s major erectile tissues.

PDE5 5 inhibitors relax smooth muscles and promote good penile function. As a result, PDE5 inhibitor medicines such as Cenforce 150 are recommended for the treatment of erectile dysfunction (ED). They also cure a variety of other male sexual issues, including as premature ejaculation.

PDE5 inhibitors are the medications of choice for treating and controlling erectile dysfunction due to their high level of efficacy and track record.

Where can I find PDE5?

PDE5 enzymes of various types breakdown cGMP. These PDE5 enzymes are found throughout the body and function in a variety of tissues. PDE 5 enzymes, for example, are found in the corpus cavernosum smooth muscle, skeletal muscle, cerebellar and pancreatic tissues, vascular and visceral smooth muscle, platelets, kidneys, and lungs.

PDE5 Inhibitors: Can They Cure ED?

PDE5 inhibitors promote vasodilation in the penile region, inhibit cGMP breakdown, and prolong the activity of vasodilator mediators such as nitric oxide. The release of nitric oxide, which encourages the creation of cGMP, is required for penile erection.

Penile erection is caused by the relaxation of smooth muscles in the corpus cavernosum, the basic erectile tissue. Nitric oxide is released from the corpus cavernosum nerve ending during sexual stimulation.

It promotes smooth muscle relaxation by increasing cGMP production in the corpus cavernosum. This increases blood flow to the penile region, resulting in an erection. However, the erection produced is not a long-term solution. The impact wears off after a few hours.

When Is the Best Time to Take PDE5?

PDE5 inhibitor medications treat three men’s health issues: erectile dysfunction, pulmonary arterial hypertension, and benign prostatic hyperplasia.

One of the most frequent sexual issues in males is erectile dysfunction. It is a condition in which males are unable to achieve or maintain a sufficient penile erection for satisfying sexual intercourse. Erectile function is affected by a variety of circumstances, and difficulties can result in reduced erectile function.

High blood pressure in the arteries leading to the lungs is referred to as pulmonary arterial hypertension. Pneumoarterial hypertension is diagnosed when the pulmonary arterial pressure surpasses 25 mm Hg. Benign prostatic hyperplasia is a prevalent condition in men over the age of 50. It is a disorder in which the prostatic stromal cells grow rapidly, resulting in an enlarged prostate gland.

What is the most effective PDE5 inhibitor?


Sildenafil is marketed under the brand name Viagra. According to clinical research, the oral dose of Sildenafil is expected to have a start of action in 30 minutes and a maximum effect in one hour. This drug’s serum half-life, on the other hand, is four hours. Furthermore, because Sildenafil is a lipophilic molecule, taking it close to the intake of a fatty meal lowers its potency. Other Viagra alternatives, such as Cenforce 100, can be found here.


Tadalafil is marketed under the brand names Cialis and Adcirca. Vidalista 20 is a prescription medication that is one of the most effective treatments for erectile dysfunction and benign prostatic hyperplasia. Adcirca is a medication that is used to treat pulmonary arterial hypertension.

Tadalafil has been demonstrated to have a 16-minute start of effect. Furthermore, using this medication near to the eating of fatty meals has no effect on its efficacy.

Vardenafil Vardenafil is marketed under the brand names Levitra, Staxyn, and Vivanza. It is one of the medications indicated for the treatment of erectile dysfunction.

Vardenafil is taken 30 minutes to an hour before sexual activity. Professionals also advise taking this medication one to two hours before or after eating a meal, as this can reduce its effectiveness. This drug’s duration and effect last for 5 to 7 hours.
