What is False about sustained release tablets - and explain in detail?
Ans. is 'b' i.e., Less chances of toxicity o A sustained-release dosage form provides an initial amount of drug sufficient to produce a desired therapeutic plasma concentration and continuously releases the drug at a constant (zero-order) rate which will maintain the therapeutic concentration for an extended period (recommended dosage interval). The margin of safety of the drug (active ingredient) is an important consideration in the selection of a candidate drug, because sustained-release products contain a large amount of the drug and the possibility of 'dosedumping' with resultant toxicity exists.
