What is Cialis?

Cialis is one of the recent prescription drug pill that is used for the treatment of erectile dysfunction. Released and approved on 2003 by the American Food and Drug Administration (FDA), Cialis is a phosphodiesterase type 5 or PDE5 inhibitor. It is a drug known to block PDE5 enzymes which has degradative properties that could affect smooth muscle cells and blood vessels of the penis.


Tadalafil and Adcirca are the other names of Cialis which in 2009 was approved for treating pulmonary arterial hypertension in the United States. Right heart failure is one of the results of pulmonary arterial hypertension if left untreated.


Cialis pills are available in dosages of 5mg, 10mg and 20 mg and has an almond shape with film-coated yellow coloring.


The Weekend Drug

What separates Cialis from other erectile dysfunction drugs like Viagra and Levitra is its thirty six hours of effectiveness . This translates to a longer duration before its half life. In comparison Cialis has a half life of 18 hours while Viagra and Levitra has about 4-5 hours. For this reason the drug got its moniker “the Weekend Drug.”


Among the three, Cialis is the only one that is could be taken as a once-daily medication although it is recommended as an “as needed” drug. It could also be taken with or without food.


The Actions of Cialis Against Erectile Dysfunction

A male experiences erection when there is a presence of touching, audio and/or visual stimulation or the thought or idea of sexual intercourse. The brain then sends signals on the blood vessels and muscle tissues to relax and allow the blood flow to the penis. When the spongy tissues have been filled with the necessary blood an erection occurs.


When absorbed by the body Cialis limits the amount of PDE5 enzymes that could cause stress on the smooth muscle cells and blood vessels thus, enhancing the erectile function with the increase of cyclic guanosine monophosphate (cGMP) that promotes blood flow and relaxes smooth muscles specially on the sexual part of males.


What dosage of Cialis should I take?

The best way to know the right dosage of Cialis for someone is to consult a doctor or physician as the drug has several side effects and is incompatible for people who have certain conditions or diseases. The dosage of the medication could also be increased but the recommended dose is at 10mg. It is important to keep in mind that Cialis should only be taken once a day.


For an anticipated sexual activity 10 mg of the medication is recommended. However, on days without regard of a planned or timing of sexual activity 2.5 mg should be taken.

Things to Avoid While Taking Cialis

There are certain food and products that should not be taken with Cialis for they could cause unwanted reactions that could harm your health. While taking the drug drinking should be avoided as well as grapefruits and its by-products for they could trigger some of its side effects.


Other medications that treats erectile dysfunction should not be taken with this drug.. Organic nitrates are also advised to be taken only after 48 hours after the intake of the medication as they could increase the risk of hypotension.
