Viagra is a drug that is also referred to as Sildenafil citrate. The drug gained initial approval from the FDA back in the year 1998 as a drug for addressing issues relating to the pulmonary system as well as hypertension. The active ingredient in this drug is known as Sildenafil. It is very important to point out that the drug functions just like Cialis, this is done by relaxing the muscles of the penis and as such leading to increased blood flow into it. The colour of Viagra is blue, it comes in a diamond shaped tablet which is available in different variants such as 25mg, 50mg, and100mg pills for the purpose of oral administration. Viagra is noted for its unique track record, it also holds a unique track record which predates all the other erectile dysfunction drugs out there and it has indeed lived up to its reputation of being the ideal erectile dysfunction drug.
Differences between Cialis and Viagra
There are a number of key features that differentiate Cialis and Viagra and few of them will be pointed out in this article:
- The effect of Cialis is apparently longer, this is because it can last as much as thirty-six hours, and meanwhile, Viagra has an effect which wears out typically within 8 hours.
- Viagra holds the reputation of acting the fastest. The effect can kick in within just thirty minutes of usage, Cialis on the other hand only becomes effective in about two hours
- Furthermore, Viagra is more prone to food interactions; hence patients should do all they can to avoid making use of the drug with some food types. These food types include those which are rich in fat. However, Cialis, on the other hand, is not so food sensitive as it has not food interactions.
Variances in mechanism of action
It must be stated that Cialis and Viagra function in ways that are alike, hence they belong to the same category of drugs known as the PDE5 inhibitors. The effect of these drugs is based on the relaxation of the muscles as well as the increase in the flow of blood. By doing this, they assist men who suffer from erectile dysfunction in obtaining an erection.
How does one know the right dosage?
When it comes to the issue of identifying the right dosage, the user should ensure to discuss his or her medical concerns and history with their healthcare provider, the reason for this is that the discussion is most likely to affect the frequency and dosage of Cialis or Viagra that would eventually be recommended.
By way of principle, doctors begin by prescribing between 5 and 10mg of the Cialis tablet and usually they tell the patients to make use of the medication within the first hour before they engage in sexual intercourse. However, if it becomes necessary, the dosage can then be reviewed up to about 20mg. when a certain patient makes use of a certain dosage of Cialis on a regular basis, it simply means that he does not need to time his sexual activities as the drug still stays within his system
