PDE5 Inhibitors – What You Need to Know

PDE5 inhibitors are drugs that prevent the breakdown of cGMP in the smooth muscles surrounding the penile arteries.

Sildenafil, tadalafil, and vardenafil are prescription medications used to treat erectile dysfunction (ED) and other male sexual health issues. Your doctor may prescribe these medications if they help you get an erection when you’re sexually aroused.

Since they’re so practical and their records are impressive, PDE5 inhibitor medications are the first-line treatment for erectile dysfunction.

Where is phosphodiesterase type 5 inhibitor (PDE5 inhibitor) Located?

There are many kinds of PDE5 enzymes which act to degrade cGMP (cyclic guanosine monophosphate). They’re found in many body parts and carry out their activities in various tissues.

An enzyme called phosphodiesterase type 5 (PDE5) is present in the smooth muscles of the corpus cavernous, skeletal muscles, cerebellum, pancreas, blood vessels, lung tissue, and kidney tissue.

Can PDE5 inhibitors cure erectile dysfunction (ED)?

PDE5 inhibitors cause vasodilatation in the penis region, prevent the breakdown of cGMP and result in the prolonged action of mediators of vasodilators like nitric oxides. Erection depends on the release of nitric oxides, which stimulate cGMP production.

Erection is a physiological response when nerves release nitric oxide into the blood vessels supplying the penis. Nitric oxide relaxes the smooth muscle cells in the corpora cavernosa, causing them to expand and fill with blood, resulting in an erection.

Cialis comes in two forms – Tadalafil (CIALIS) and Dapoxetine (DAPOXETINE). Both these drugs work by increasing levels of nitric oxide in the body. Nitric oxide relaxes muscles around blood vessels and helps them widen so that more blood can enter the erectile tissue.

When Should I Take PDE5?

Drugs that belong to phosphodiesterase type 5 (PDE5) inhibitors treat three men’s conditions: erectile dysfunction, pulmonary arterial hypertension (PAH), and benign prostatic hypertrophy (BPH).

Erectile dysfunction (ED) is one of the most commonly reported sexual issues among men. ED occurs when a man cannot achieve an adequate level of arousal for successful penetration. Physical conditions, psychological disorders, medications, or lifestyle choices may cause ED.

Pulmonary arterial Hypertension (PAH) occurs when the pulmonary artery pressure increases above 25mm Hg. PAH is characterized by increased resistance to flow through the pulmonary vasculature.

Benign Prostatic Hyperplasia (BPH) is a common condition among older males by age 50. It is when the rapid increase of the stromal cells in the prostatic tissue causes an enlarged prostatic gland.

Which are the best PDE5 Inhibitors ?


One notes that the oral doses of Sildenafil expect an onset of action in thirty minutes and the estimated maximum effects at one hundred minutes.

However, the half-life of this medication is four (4) hrs. Also, this medication is a lipophilic compound, so taking a dose near the time of eating a fatty meal decreases its effectiveness.

Tadalafil (Cialis) treats erectile dysfunction and benign prostatic hypertrophy. Adcirca (Pulmonary Arterial Hypertensión) is used to treat pulmonary arterial hypertension.

Tadalafil works best when taken within 2 hours before eating. However, consuming a meal doesn’t affect its effectiveness.


Vardenafil (Levitra) is used to treat erectile dysfunctions.

Vardenafil works by relaxing muscles in the penile region so that they become less tight during sex. It remains effective for up to seven (7) hrs.

Caffeine, which is present in most people’s daily diet, has a mixed reputa­tion for treating erectile dysfunc­tion. However, phosphodiesterase 5 (PDE5) enzymes break down cGMP inside cells.

Headaches, flushes, stomach discomfort, muscle and back pain, and even nausea are common side effects of a cold.
