We have observed that the degradative action of cGMP is activated in our bodies when under stressful situations. This degradative action which is specifically working upon the cGMP is known as PDE5.
This PDE5 attaches to the smooth muscles and deactivates cGMP due to which the blood vessels start contracting. These blood vessels, called corpora cavernosa, carry blood to and from the penis.
In this situation, the quantity of blood coming to the penis decreases which causes softer erections and premature ejaculation. In the long run, the activation of PDE type 5 gives rise to erectile dysfunction. It is a serious sexual disorder that happens in the body of males.
Now keeping in mind the issues that are happening in the body of the person, consuming a medicine is very important. Because if we neglect the issue for longer then it can lead to sexual dissatisfaction among the couples. In such situations, consuming the PDE 5 inhibitor medicine is a solution.
We will be discussing the medical details which include the issues with which the medicine helps, different types of PDE5 inhibitors, and many more. So, let’s get started without any further ado.
Issues Resolved By PDE 5 Inhibitor Medicines
A list of issues for which PDE5 inhibitor medicines are helpful is provided below:
Erectile Dysfunction :
Erectile Dysfunction is the main issue for which the medicine first hits the rack. This issue decreases the satisfaction that a person has while having sexual activity and the levels also.
Two major symptoms of erectile dysfunction are early ejaculation and weak erections. With this medicine help, a person can get temporary relief from these issues. Due to this, they are again able to enjoy their sexual life better than normal.
High Altitude Illness:
In this issue several people start feeling sick as they reach a certain altitude due to a decrease in oxygen levels. When a person takes a pde5 inhibitor in this case, then they are able to fight the altitude sickness better.
The results of testing of PDE 5 inhibitors on canines and mice are very promising. It shows that heart disease improves with the consumption of this medicine which decreases the chances of heart failure.
Diabetic Nephropathy :
Insulin sensitivity improves due to the consumption of PDE-5 inhibitor which in return has improved the situation of diabetic nephropathy.
There is an issue known as oligospermia in which the motility of sperms decreases. Due to this the overall fertility of a male decreases. When such a person consumes the medicine then their sperm motility increases slowly.
Peripheral Arterial Disease (PAD):
In this the diameter of the arteries and vessels is reduced due to which the flow of blood to limbs is highly affected. With the help of PDE 5 inhibitors, the diameter of blood vessels can be increased successfully which helps in getting rid of the issue.
Lower Urinary Tract Symptoms (LUTS):
This is an issue that happens in the body due to benign prostatic hyperplasia. When you consume the PDE 5 inhibitors along with Alpha-blockers, then you can see amazing results and improvement in the issue of LUTS.
Penile Rehabilitation after Radical Prostatectomy:
The medicine has a lot of neuro regenerative effects on the nerves that affect the functioning of the penis. That is why consuming the medicine after you have your radical prostatectomy can help you in gaining a happy sexual life back.
Different Types of PDE5 Inhibitors
Different types of FDA-approved PDE5 inhibitors are listed below:
- Sildenafil Citrate – This medicine is sold under the brand name Viagra and is the most effective in the category. The medicine takes half an hour to activate in the body and stays active for 3 to 4 hours.
- Tadalafil – The medicine is sold under the brand name Cialis. The medicine takes one hour to activate the salt and it is known to stay active for 24 hours.
- Vardenafil and Avanafil – Both of these medicines are also available in the market as PDE 5 inhibitor medicine.
How Does a PDE5 Inhibitor Work in the Body?
The working of PDE 5 inhibitor medicine is very simple and has two basic focuses. The first aim of the medicine is to inhibit all the tasks and changes made by PDE in the body.
The second aim is to reverse the changes that are already made by PDE in the body.In the case of erectile dysfunction, the PDE5 inhibitors enter the blood vessels carrying blood to the penis.
After that, it finds PDE and blocks them to carry on any further action in the body. As the PDE gets blocked, cGMP again gets activated.
This cGMP acts on the softer muscles of blood vessels and dilates them. After dilation the blood flow to the penis increases which is beneficial for your erection as it gets harder.
As long as the blood vessels remain dilated, the blood flow to the penis will remain constant. This is going to help a person out with the issues of erectile dysfunction.
