A generic is a drug containing the same active ingredient as the original, but with different adjuvants. In addition, the generic does not usually spend large clinical trials unlike the brand name drug. We can say that generics are substituted for brand name drugs. Generics are cheaper and therefore more accessible. Many were created for generic double "Viagra", "Levitra" and "Cialis." Most of them are of Indian origin. Some believe that the generic drug "Viagra" and "Cialis" are less effective, while others claim that the results of their use are the same as in the original treatment. It should be noted that generic drugs are very different. Some companies have a pharmacological responsible attitude towards the process of drug development and good products. Other companies allow themselves to production errors or have a research base products of poor quality. These drugs are ineffective.
