1.	Which of the following statement is false for osmotic pumps?(a) The pump has three concentric circle(b) The innermost is the drug reservoir(c) The drug is contained a permeable polyester bag(d) Outer most rigid rate controlling semipermeable membraneI got this question in an online quiz.The query is from Biopharmaceuticals topic in section Biopharmaceuticals of Drug Biotechnology
Answer» The correct option is (c) The drug is contained a permeable POLYESTER BAG The BEST I can explain: The pump is MADE of three concentric layers. The innermost reservoir is contained in a collapsible impermeable polyester bag. The OUTERMOST is a rigid, rate controlling semipermeable membrane made from substituted cellulosic polymers.
