It began in the three years of 1998 when sildenafils was marketed under the trade name Viagra which became a brand name and brought about a radical change in the management of erectile dysfunction.
Sildenafils is known to function as PDE5 inhibitor effectively controlling blood flow within the penile tissues. Usually, sexual arousal provokes the release of nitric oxide in the penis area, activates an enzyme, and results in the creation of cGMP. This cGMP relaxes smooth muscles and increases king’s flow to the penile tissue to facilitate the erection. Since PDE5 is responsible for degrading cGMP, the drug prevents the breakdown of this compound by blocking PDE5, which aids and increases the endurance of erections.

How to Sildenafils work for Erectile dysfunction?
Sildenafils or widely known as Viagra is a drug that addresses the issue of erectile dysfunction in men extensively. ED is the condition that makes a man incapable of getting or sustaining an erection for purposes of sexual intercourse. Sildenafil acts as a cocktail to the natural occurring chemical in the body known as nitric oxide that is responsible for the relaxation of muscles in the penis.
Here’s a simplified breakdown of its mechanism:Here’s a simplified breakdown of its mechanism:
- Nitric Oxide Release: When a man get sexually excited,the substance called as nitric oxide is produced in the erectile tissues of penis.
- cGMP Production: This nitric oxide triggers the activation of an enzyme known as guanylate cyclase which has the effect of heightening the levels of cyclic guanosine monophosphate (cGMP). cGMP plays a central role in regulating the spas and constriction of the vessel that supply blood to and from the penis.
- Blood Vessel Relaxation: cGMP leads to the relaxation of smooth muscles of small blood vessels in the corpus cavernosum which is the erectile tissue. This relieves constriction allowing blood to fill the veins in the penis easily.
- Erection Occurs: The result of this is an erection since there is a good blood flow.
Sildenafil is known to affect one of the enzymes known as phosphodiesterase type 5 (PDE5) in the body. PDE5 metabolises cGMP, thus when this enzyme is inhibited by sildenafils, it means that cGMP will accumulate in the body. This action assists in retaining the state of erectile tissue’s blood vessels’ dilatation and supports the erection.
One thing that should be highlighted about sildenafils is that it only acts per its function when the person is sexually stimulated. They point out that while sexual desire remains unaffected, the physiological reaction to it does improve. Sildenafil usually takes approximately 30 to 60 minutes before it is effective and its ability can last up to, four hours. Other potential side effects could be mild ones such as headaches, flushing and indigestion and nasal congestion in those who take the drug.
Drugs interaction of Sildenafils
Sildenafils is a drug mainly used to address erectile dysfunction and pulmonary arterial hypertension but popularly known under the trade name Viagra. When taken, it causes the action of the enzyme phosphodiesterase type 5 (PDE5) to reduce, and this allows for an increase in blood flow to the penis, for an erection in cases of sexual stimulation.
However, sildenafils can pose some interaction with existence of other drugs, with potential severe consequences. One of the potentially most serious interferential processes concerns nitrates used for the treatment of chest pain or angina. sildenafils if used together with nitrates, can prove to be lethal to the body as it leads to a considerable drop in blood pressure and this results in dizziness, fainting, tendency to have heart attack and tendency to have a stroke.
Another crucial interaction is with alpha-blockers that is commonly prescribed in cases of high blood pressure as well as prostate problems. These, when taken together with sildenafils can also cause a dangerous drop in blood pressure. Also, some drugs used in treatment of fungal infections like ketoconazole and itraconazole, and some antibiotics like erythromycin and clarithromycin, increases concentration of sildenafils in the blood, increasing the possibility of side effects.
Also, over the counter drugs such as protease inhibitors that are administered in the treatment of HIV display the ability to raise levels of sildenafils hence requiring dosage alteration. Sildenafil metabolism can also be affected by grapefruit and grapefruit juice, thus increasing the instances of the side effects.
Wald and Levitt stated that patients should disclose to their healthcare provider all the medications and supplements they are taking since some may lead to those risky drug interactions. In order to avoid side effects using of sildenafil, it is necessary to follow recommendations of doctors and follow directions on dosage forms.
