Answer»

Correct answer is (b) Two or more drug products are identical in quality, purity, uniformity, DISINTEGRATION, dissolution

The best explanation: Pharmaceutic equivalence implies that two or more drug products when they are identical in strength, purity, content uniformity, and disintegration and dissolution characteristics. Though the EXCIPIENTS may differ. Chemical equivalence of drug products is SAID when the drugs contain the same active ingredient. The amount of the active ingredient MUST be the same. When two or more drug products contain the same active ingredient giving the same pharmacologic effect is KNOWN as therapeutic equivalence.
