Sildenafil Vs Tadalafil: Which is a Better Drug?

These two drugs are the most used when it comes to treating impotence or also known scientifically as Erectile Dysfunction. These two drugs are at the top. Sildenafil and Tadalafil are their drug names but are commonly known by people as their brand names which are Viagra and Cialis. Both of these drugs work wonders in the human body by the task that they do, enabling men who were previously struggling with their sexual health to regain their robustness in the bed back.

Sildenafil is Pfizer’s product. Released back in 1997 as Viagra, it is the first ever drug that was able to effectively cure Erectile Dysfunction. Sildenafil is also known as an inhibitor drug, an inhibitor of the enzyme in the body also known as PDE 5 or Phosphodiesterase type 5 that when repressed, relaxes the muscles surrounding the blood vessels and dilating them, allowing an improved circulation of blood in the body. It helps the penis achieve an erection by ensuring a steady and increased blood flow to the organ, giving the patient a sturdier and long-lasting erection which is even better than the usual erectile response. Aside from treating impotence, Sildenafil is also used for patients affected by Pulmonary Arterial Hypertension, a type of high blood pressure caused by the pulmonary arteries that have grown too thick for smooth blood flow.

In response to Pfizer’s Sildenafil, Eli Lilly and Co. has developed Tadalafil, a drug that has the same function as Viagra and introduced it in the market under the name Cialis. Tadalafil, just like Sildenafil, is also a PDE 5 inhibitor drug that improves the circulation of blood in the body and increases the blood flow to the patient’s penis assisting it in achieving an erection. Though having a different formulation, Tadalafil’s effects are identical to what Sildenafil does. Eli Lilly and Co. has also manufactured Adcirca, its other Tadalafil product line for Pulmonary Hypertension. Tadalafil is also used for treating Benign Prostatic Hyperplasia or BPH in patients, also known as the enlargement of the prostate.

Though these two drugs are more similar than different, there are some key differences between their effects on the body. The speed of Tadalafil’s effect compared to Sildenafil is a lot faster, acting for as quick as 30 minutes after ingestion, compared to Sildenafil which needs 1 hour before taking effect. This is of course under the right circumstances that the drugs are not taken with fatty foods or with a full stomach which affects the speed of how the drug is absorbed by the system.

When it comes to the length of effect, Tadalafil has the advantage over Sildenafil. If Sildenafil only has 5 to 6 hours of effectivity, Tadalafil has an effectivity window of 24 to 36 hours. This does not mean that the patient will have a prolonged erection which lasts for 36 hours but it means that whenever the patient needs an erection within the given time window, Tadalafil would be able to help the body with its erections.

The strength of action is also a factor where these two drugs are pitted against each other. Many of the Sildenafil users who have already tried using Tadalafil before have noticed that Sildenafil has a more explosive effect. Tadalafil helps the patients get an erection but it seems that for many, they get a harder erection from Sildenafil. This may be more of a case by case basis issue since the drugs do tend to work differently to different people. Some do find Tadalafil better while others prefer Sildenafil. In the end, it narrows down to personal preference and what drug the doctor will recommend to the patients.
