Cialis vs Viagra: Two of the Most Popular ED Treatments Compared

Cialis and Viagra are two of the most popular treatments when it comes to managing impotence in males. Viagra, the world’s most popular erectile dysfunction (ED) medication, came first, though its discovery fortuitous.

Sildenafil Citrate, the active pharmaceutical ingredient of Viagra was developed for the management of angina in patients but turned out to be an effective erectile agent, to the surprise of many. Cialis, on the other hand, was an improvement in the initial formulation of the Sildenafil Citrate drug; Cialis was created to aid patients to enjoy their erectile function much longer.

Cialis and Viagra Tablets

Both drugs are widely available internationally at local drugstores but are also widespread online. Almost all online shops carry both drugs in their rosters because of the increased demand for these drugs by the consumers.

Cialis vs Viagra: Comparison

Cialis and Viagra both belong to a single drug class called PDE5 inhibitors (phosphodiesterase type 5 inhibitors), but despite being in one drug family, there are considerable differences identifiable for the two impotence drugs. To help you know the similarities and differences of Cialis and Viagra, we’ve come up with this table for your reference:

CIALIS VIAGRA
Manufacturer Eli Lilly Pfizer
Active pharmaceutical ingredient Tadalafil Sildenafil Citrate
Formula C22H19N3O4 C22H30N6O4S
Indications Erectile dysfunction, premature ejaculation, pulmonary arterial hypertension Erectile dysfunction, premature ejaculation, pulmonary arterial hypertension
Biological half-life (duration in the body) 17.5 hours 3-4 hours
Prescription Status Rx (Prescription only) Rx (Prescription only)
Routes of administration By mouth By mouth, intravenous

As illustrated by the table above, although these two drugs belong to the same drug family, they are different in terms of several aspects such as their biological half-life and their active pharmaceutical ingredients.

Cialis has its active ingredient Tadalafil, while Viagra has the ingredient Sildenafil Citrate. Although these active ingredients have the same action, they last differently in the body. Sildenafil Citrate in Viagra lasts for up to 4 hours in the body, while Tadalafil has a biological half-life of 17.5 hours and as some reports say, up to 36 hours, hence dubbing Cialis as the “weekend pill”.

Also, because Sildenafil in Viagra has a shorter duration, the drug should be taken in about 1-4 hours prior to the intended sexual activity. The intake of Cialis, on the other hand, may be done at least 2 hours (or more) prior to intercourse.

Apart from the differences in the course of action, Cialis also differs from Viagra by the available formulations. Viagra is available as a single-use product (available in 25 mg, 50 mg, and 100 mg forms), while Cialis is available in the single-use product, as well as a “daily” variant, like a “maintenance treatment” for impotence.

Cialis vs Viagra: Mechanism of Action

Because both Cialis and Viagra exist in the same drug family of PDE5 inhibitors, their mechanisms of action are the same. Tadalafil in Cialis and Sildenafil Citrate in Viagra are both potent vasodilators; these active pharmaceutical ingredients instigate vasodilation and smooth muscle relaxation in the penile tissues, encouraging greater blood flow which aids the patients’ erectile response.

Even if impotence has various root causes, both Cialis and Viagra target impotence of various origins. Patients can expect the restoration of their erectile response, provided that they follow their doctor’s instructions for the intake carefully.
