While Cialis and Viagra are nearly identical, several crucial differences may make one drug a better choice for you than the other. We have compared Cialis and Viagra on various criteria, including their effectiveness on treating ED, duration of action, and potential adverse effects. Read more to find out.
What is Viagra?
Viagra is a brand-name drug used to treat erectile dysfunction (ED). It includes the active component Sildenafil, and was initially developed by Pfizer in the 1980s and early 1990s as an angina therapy (a medication for chest pain caused by certain heart conditions).
The Food and Drug Administration approved the distribution of Viagra in 1998, making it the first prescription medicine for treating ED. It is a widely sold medication for ED used by millions of men with erectile problems globally.
Both Viagra and generic Sildenafil are available as oral drugs. You can take Viagra as a pill before intercourse. A standard dose of Viagra takes around 30 to 60 minutes to start functioning and offers relief from erectile dysfunction.
Note: The standard dosages for Viagra come in 2.5mg, 5mg, 10mg, 20mg.
What is Cialis?
Like Viagra, Cialis is also a brand-name prescription medicine licensed by the FDA to treat ED, which includes Tadalafil as its active ingredient.
Tadalafil, the key component in Cialis, received FDA approval in 2003. Today, Tadalafil is more popularly known as Cialis. It is an oral tablet for usage before intercourse, similar to Viagra.
Note: The standard dosages for Cialis 25mg, 50mg, and 100mg.
How Cialis and Viagra Work
Both Cialis and Viagra work by blocking the actions of an internal enzyme called Phosphodiesterase type 5 (or PDE5, for short) and activating the nitric oxide chemical in the body This helps in the relaxation of the penis muscles allowing more blood flow during an arousal.
Which Lasts Longer: Cialis or Viagra?
Although Cialis and Viagra work similarly to enhance blood flow to your penis and cure ED, there is a considerable difference in how long each tablet remains active in your body.
Cialis is a long-lasting treatment for erectile dysfunction. Because it can last longer, it’s commonly referred to as the “weekend pill” for treating ED. Cialis or generic Tadalafil will last for around 36 hours. This long-lasting impact makes Cialis a practical option if you suffer erectile dysfunction but are uncertain about the time of the sexual intercourse.
On the other hand, Viagra is recommended for use when you need to address this condition before sex.
Does Food Influence the Effects of Cialis or Viagra?
Cialis and Viagra, like other oral drugs, are broken down by your stomach acids, allowing them to move past your liver and into your blood system.
Food does not influence your body’s ability to absorb Cialis, so you may take your daily dose without worrying about your diet. Cialis should start working in 30 minutes to one hour, even if you take it with a large meal.
On the other hand, food has a more significant impact on Viagra’s effectiveness. While it is safe to take Viagra with food, taking it after a high-fat meal (such as fried food or a cheeseburger) may lengthen the time it takes for the medicine to operate. Consult the doctor on your diet plan while taking Viagra.
