viagraThe constant advancements of modern medicine have allowed us to fight off a lot of diseases and medical conditions. As the years go by and science progresses even further, we are acquiring ever new and different treatment options to address particular issues that are guaranteed to cover all types of patients.

One such case is erectile dysfunction. The two most popular drugs that are used to treat the condition are Viagra and Cialis. In this article we are going to compare these two so that potential users have a complete understanding of both before deciding which one suits them the best.

Active ingredient

Both of the drugs’ active ingredients belong to the same group of substances called PDE-5 inhibitors. Cialis contains tadalafil while Viagra contains sildenafil.

Prescription requirement

They both require a doctor’s prescription to be purchased. However, there are quite a few online pharmacies where these drugs can be bought anonymously without a prescription.

How they work

They both work similarly since they belong to the practically the same chemical category: PDE-5 inhibitors block the action of cGMP-specific phosphodiesterase type 5, an enzyme that is “responsible” for the inability of men to achieve and maintain an erection.

Price

Viagra and Cialis are similarly priced, although generally speaking the latter is priced somewhat higher. For instance, 20mg tablets of Cialis cost on average between $10 and $14 per tablet, depending on the number of pills you are purchasing. Viagra does not come in that dosage; the standard tablet of Viagra contains 100mg of sildenafil, for which you will have to pay about $10.

“Kick in" time

cialisAccording to men who have tried both of the products, Cialis seems to be faster acting. It normally takes about 20 to 30 minutes for it to start working, though in some cases men report that the medicine starts working only 15 minutes after consumption. Viagra is a bit slower and it normally takes about 30 minutes to an hour before it starts to take effect.

Duration

Cialis is the clear winner in this category since it has been documented to last for about a day and a half (36 hours), while Viagra is active only for up to 6 hours after consumption.

Success rate

Viagra's effectiveness has been tracked to be 81%, meaning it works for 8 out of every 10 men that have used it. Cialis’ rate is approximately the same, but for people who care about exact figures, it is actually 1% more effective at 82%.

Directions

Cialis can be taken on either an empty or full stomach with the only exceptions of grapefruit and greasy foods. Viagra works better when taken on an empty stomach in order to avoid prolonging the “kick in” time or reduced effectiveness levels.

Possible side effects

Cialis has been documented to be have somewhat fewer side effects than Viagra. They include sudden flushing in the area of the face, blood pressure drop, congestion and dizziness. Viagra’s common side effects include nausea, diarrhea and a sudden difficulty in distinguishing between the colors blue and green. Headaches are a common side effect of both Cialis and Viagra.

It seems that Cialis is a somewhat better choice than Viagra for a few reasons. For starters, it requires a smaller dosage to work, a characteristic that is a huge advantage for many men since it limits the potential side effects. In addition, Cialis lasts much longer than Viagra. The advantage of this is that there is no need to plan on taking the drug shortly before sexual activity. It is because of this property that Cialis has been given the nickname "The weekend pill“, since a single pill taken on a Saturday morning is guaranteed to last for almost the entire weekend.

However, the factors that are used as buying criteria may differ from one person to another. Thus, the final conclusion and choice depends on the consumer. Some consider the price to be the most crucial factor, while others focus on the duration. There is also the factor that an individual finds that one drug might be simply more effective than the other due to reasons that have to do with how his body responds to each drug.
