Viagra, Cialis, and Levitra A Comparison
The drugs of Viagra, Levitra, and Cialis all have one thing in common they are anti impotence drugs all aimed at men with erectile dysfunction or ED. Men with erectile dysfunction experience no erection at all due to hardening of the smooth muscle in the penis. This leads to the blood vessels inside the penis being constricted. With incorrect blood flow and oxygen, an erection cannot occur. With taking the drugs mentioned above, this problem can be fixed. They all release nitric oxide which increases the blood flow and oxygen flow while relaxing the muscle in the penis.
There are some differences however in the way that these three drugs work, so we will look at them in more detail below:
Viagra is effective for 4 hours so you should take it about 4 hours before sexual intercourse. The Cialis on the other hand has 36 hours of effectiveness, meaning that whenever you need it during this time you will be able to have an erection. With the Cialis, you do not have to take it at a certain time to have an erection a few hours later. You have more freedom than you do with Viagra. The Cialis must be taken at the same time every day and you can just get an erection when you are sexually aroused as you normally would. This is considered more of a cure than Viagra which is a once off solution when you need it.
The other erectile dysfunction drug called Levitra also produces an increased blood flow which assists with the penis becoming erect and also relaxes the smooth muscle. This drug is said to have no side effects that Viagra has for the heart and for vision upsets. It uses Vardenafil HCL inhibitor to increase the blood flow as opposed to nitric oxide and therefore also works a lot quicker than Viagra which takes about 1 hour to have an effect.
The Levitra, an orange pill, is supposed to be effective 89 percent of the time which is only slightly more than that of Viagra. Both drugs are inhibited by eating a very fatty meal, although it seems as though Levitra is more resistant to this. Both have the same side effects and although Levitra starts working faster, it also lasts about 4 hours like Viagra.
Comparing the two with regards to the dosages, Levitra has a much lower dosage as its maximum, although you should bear in mind that the ingredients are different. With Viagra, the maximum dose is 100 mg while the Levitra offers a 20 mg max. On the other end of the scale, Viagras minimum is 12.5 mg which there are no pills for, and Levitras is 2.5 mg which there are pills for.
