I normally get the bigger oval pink pills but this time they didn't have those so I got the oval white Watson 540 ones. These seem to have a much bigger effect than the others. Anyone know why?
A generic drug is equivalent to it's brand name counterpart, but is usually much less expensive. A generic drug must have the same active ingredients, route of administration, dosage form, strength, and indications as the original brand product. Generic drugs are approved by the U.S. Food and Drug Administration, and are deemed to be as safe and effective as the brand name product.
Generics cannot be sold until after the drug patent expires on the original brand name product. For example, generic fluoxetine could not be sold until the patent had expired on the brand name equivalent Prozac. A drug manufacturer applies for a patent to protect their drug from being copied and sold by another company and losing profits.
Patents typically expire 20 years from the date of filing. During this period of patent protection, only the original manufacturer can research, develop and sell the brand name drug. When the patent expires, other manufacturers can submit an abbreviated new drug application (ANDA) to the FDA for approval to market the generic version.
Generic drugs have lower research costs and increased market competition and those substantial savings are passed on to the patient. However, generic drugs still must meet strict FDA requirements with respect to quality, performance, labeling, manufacturing, and bioequivalence. By law, generic drugs must have the same active ingredients as the brand name product, and they can be expected to have the same effect when used in place of a brand name drug.
A generic drug is a drug that is exactly the same as the brand-name drug, but can only be produced after the brand-name drug's patent has expired.
A generic drug is the same as a brand-name drug in:
the way it works
the way it is taken
the way it should be used
A drug company develops new drugs as brand-name drugs under patent protection. This in turn protects the investment in the drug's development by giving the drug company the sole right to manufacture and sell the brand-name drug while the patent is in effect.
When patents or other periods of exclusivity expire, other manufacturers can submit an abbreviated new drug application (ANDA) to the FDA for approval to market a generic version of the brand-name drug.
Although generic drugs are chemically identical to their branded counterparts, they are typically sold at a cheaper price than the brand-name drug because the drug has not been developed from scratch, and the costs to bring the drug to market are less.
Are generic drugs as safe as brand-name drugs?
Yes. The FDA must first approve all generic drugs. The FDA requires that generic drugs must be as high in quality, and as strong, pure and stable as brand-name drugs. Generic drugs use the same active ingredients as brand-name drugs and work the same way. They have the same risks and the same benefits as the brand-name drugs.
If brand-name drugs and generic drugs have the same active ingredients, why do they look different?
In the United States, trademark laws do not allow generic drugs to look exactly like the brand-name drug. However, the generic drug must have the same active ingredients. Colors, flavors, and certain other parts may be different but the effectiveness of the drug remains the same.
