What is a Generic Drug?
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Product Details
Description
Your doctor may prescribe Mytesi to treat non-infectious diarrhea in adult patients who have Human Immunodeficiency Virus (HIV) or Acquired Immunodeficiency Syndrome (AIDS) from HIV. The patient must be on antiretroviral therapy.
Mytesi works by inhibiting a protein in the intestines called cyclic adenosine monophosphate (cAMP)-stimulated cystic fibrosis transmembrane conductance regulator (CFTR) chloride ion channel. It also blocks calcium-activated chloride ion channels in the enterocyte luminal membrane.
People with HIV/AIDS infection are at high risk for side effects like diarrhea when taking antiretrovirals. These types of medications are used to control HIV/AIDS infection.
