For about yen years Viagra and Cialis, two most popular erectile dysfunction medicines from the group of PDE-5 inhibitors, have been fighting for the garland of victory. This competition includes not only the branded medicines, produced respectively by companies Pfizer and Eli Lilly (both based in the US), but also their generics. Let’s get this straightened out, which generic medicine to choose if you suffer from a decrease in potency.
The active substance of all generics of Viagra and, of course, branded pills, is Sildenafil citrate. Cialis and its generics contain Tadalafil. Both ingredients are inhibitors of the enzyme PDE-5, but Tadalafil was synthesized later than Sildenafil: 2003 vs 1998. The main difference between the main active substances of generic Cialis (Vidalista) and Viagra is that Tadalafil has a milder effect on erection, which, however, lasts longer than the one of Sildenafil.
What Is Treated
Generic Viagra is prescribed for treatment of erectile dysfunction of psychological and physical etiology, as well as generic Cialis. However, the latter has additional indication: it is rather widely used for combating benign prostatic hyperplasia (BPH, also known as prostate adenoma). Other medicines against impotence are contraindicated for patients with BPH.
What Are The Dosages?
Generic Cialis pills are produced in dosages of 5, 10 and 20 mg of Vidalista generic from India. Analogs of Viagra are available in pills containing 25, 50 and 100 mg of Sildenafil. The maximum daily dosage (20 mg for Cialis and 100 mg for Viagra) must not be exceeded, otherwise the patient’s organism can be harmed.
How Should I Take It?
A pill of Generic Viagra is swallowed with water 30 minutes or an hour before sex. Generic Cialis pill can be taken either the same way, or daily. If you choose daily scheme of treatment, the time of the intake doesn’t matter – the medicine can be taken at any time of the day, regardless of whether a man is going to have sex or not.
Both Tadalafil and Sildenafil don’t cause addiction in men and can be taken as long and often as necessary to achieve a positive effect on potency.
When taking generic Viagra, pay attention to the fact that its active substance gets absorbed into the blood much slower if one takes it after a heavy meal. In case of generic Cialis, food intake doesn’t affect the speed of the onset of the effect of Tadalafil.
How Long Do These Meds Work?
Generic Cialis lasts up to 36 hours after the intake, and exactly this property makes daily reception of this medicine possible. Once a man experiences sexual arousal, the effect of the drug is preserved for about four hours.
As for generic Viagra, it can be used only on demand, because its action lasts for only four to five hours after you take a pill.
What About The Prices?
The prices of generic Cialis and generic Viagra are almost the same, especially if you consider drugs made in Canada and India. On average, one tablet of Tadalafil costs about $ 0.5 less than Sildenafil.
