What are PDE5 Inhibitors?
The family of drugs used to treat erectile dysfunction is known as PDE5 inhibitors. Phosphodiesterase 5 inhibitors were first identified to treat angina and excessive blood pressure. Yet, it was unintentionally shown to be effective for treating erectile dysfunction by a reputable source, Pfizer. It is regarded as one of the most effective treatments for treating sexual dysfunction in males of all ages. In the globe, there are reportedly more than 60 million meals addressing sexual issues. This issue used to just affect older males, but as lifestyles changed, it began to affect younger men as well. Those are often used to treat erectile dysfunction symptoms, which are typically brought on by inadequate blood supply to the penis.
PDE5 Inhibitors: How Do They Work?
PDE5 inhibitors directly affect the penis, causing the blood vessels to loosen up as a result. Erection is made possible by better blood flow in the area.
The erection process is really complicated. The nervous system around the penile area is stimulated during sexual activity. Nitric oxide is a kind of molecule that is released as a result of this process (NO). Nitric oxide in undetermined quantities enhances the exposure of cyclic GMP, a different chemical. This chemical increases the blood flow in the penile area by 40 times and aids in relaxing the blood vessels muscle.
PDE5 inhibitors help to degrade cyclic GMP molecules and reverse the erection process. They have cyclic GMP-like structures that prevent Phosphodiesterase 5 inhibitors from causing this breakdown. Nitric oxide is enhanced by this mechanism, supporting blood flow in the penis area.
Effects of phosphodiesterase 5 inhibitors
Many of the typical adverse effects include
- Headache
- Flushing
- Indigestion
- Eyesight issue
- Back pain
- muscle ache
The four main categories of Phosphodiesterase 5 inhibitors are as follows:
Sildenafil (Viagra)
The FDA granted permission for Sildenafil Citrate, often known as Viagra, to be the first widely used PDE5 inhibitor in 1998. Clinical professionals advise treating erectile dysfunction in males. Usually, it takes an hour for its effects to be felt on the body. The four-hour half-life of Viagra’s effects. Fildena double 200 contains Sildenafil Citrate as an active component.
Tadalafil (Cialis)
In 2003, tadalafil was introducing to the market to treat erectile dysfunction. Usually, it takes 20 minutes to begin acting. It has to be consum 30 minutes before engaging in sexual activity. FDA also approved laughter as a treatment for benign prostatic hyperplasia (BPH). The longest action in PDF5 innovators is tadalafil. It might persist between 24 and 36 hours. The daily dose of tadalafil ranges from 2.5 to 20 mg.
Vardenafil (Levitra)
In 2003, vardenafil received approval to treat erectile dysfunction. It began exhibiting results within 10 minutes, making it the Phosphodiesterase 5 inhibitor with the fastest onset. The typical duration of Vardenafil is 6 to 8 hours. Vardenafil PDE-5 inhibitors are use in doses of 5 to 20MG daily.
Avanafil (Stendra)
The newest PDE5 inhibitor, Avanafil, first entered the market in 2012. For its effects to be felt by the body, it takes 30 to 45 minutes. In comparison to Sildenafil, Vardenafil, and Avanafil last longer. That goes on for around five hours. Throughout a 24-hour period, you may take a dosage of 50 to 200 mg.
Inhibitors of phosphodiesterase 5 for erectile dysfunction
PDE5 inhibitors are a class of drugs often use to treat male impotence. This drug works particularly well for ED caused by physical conditions including inadequate blood flow to the penis. They do not work well to treat erectile dysfunction brought on by physical reasons like stress or worry, however.

Conclusion
Erectile dysfunction, which is cause by insufficient blood flow to the penis, maybe treat using a class of medications call PDE5 inhibitors. These drugs work by blocking the enzyme that PDE5 uses. They achieve their effect by acting directly on the penis, which causes the blood vessels in the area to relax and results in an increase in the volume of blood flowing through the region. They also contribute to the degradation of cyclic GMP molecules, which helps to reverse the process of getting an erection. A headache, flushing, indigestion, vision problems, back discomfort, muscular aches, and weariness are some of the adverse effects that might occur.
Phosphodiesterase 5 inhibitors may be broken down into four primary categories: sildenafil citrate (the active ingredient in Viagra), Tadalafil (the active ingredient in Cialis), Vardenafil (the active ingredient in Levitra), and Avanafil (Stendra). Viagra was the first PDE5 inhibitor to gain widespread usage. It has a half-life of four hours and a daily dosage range of 2.5 mg to 20 mg. The Tadalafil effect may last anywhere from 24 to 36 hours, making it the PDF5 innovator with the greatest duration of action. PDE5 inhibitors are a family of medications that are often use to treat male impotence. However, these medications are not very effective in treating impotence that is cause by physiologic factors such as anxiety or stress.
