drug is assigned only one generic name selected by the U.S. Adopted Name Council, and the name is not

capitalized. The brand name is equivalent to the trade name and is capitalized. Although the brand name

a drug while it is undergoing investigation and is often a combination of capital letters and numbers, the

products are said to differ in their bioavailability. The potency of a drug is a function of the amount of drug

required to produce an effect. The efficacy is the maximum intensity of effect or response that can be
cf cf cf cf cf cf cf cf cf cf cf cf cf cf cf cf cf cf
