1.	Which of the following is a characteristic of microspheres?(a) Free flowing powders(b) Aqueous solutions(c) Control drug release by partitioning the drug from the oil(d) Administration of emulsionsThis question was addressed to me by my school principal while I was bunking the class.This key question is from Biopharmaceuticals topic in portion Biopharmaceuticals of Drug Biotechnology
Answer» Correct choice is (a) Free flowing powders The explanation: Microspheres are free flowing powders consisting of spherical particles of size less than 125 MICRONS which can be suspended on a suitable aqueous vehicle. This SOLUTION can then be injected by 18-20 NUMBERS of injections. Each particle is a MATRIX of drug dispersed.
