Generics prescription drugs are drugs that have the same ingredients, doses, effectiveness, safety, routes of administration, quality and performance characteristics as brand name drugs. Colors, flavors and some inactive ingredients may be different, but the overall effect of the drug is the same. Generic drug is a drug which is produced and distributed without patent protection. They work the same way and in the same amount of time as brand names and generic drugs have to meet the same rigid standards as the brand names.

This substitute medicine should meet the pharmacokinetic and pharmacodynamic standards. This generic medicine is typically 20% to 90% less expensive than the brand-name original. In addition, the availability of lower-priced generic medicines brings down the price of originator drugs through market competition, producing even further savings to users.
