What is the characteristic of dissolution controlled release systems?(

1.	What is the characteristic of dissolution controlled release systems?(a) Release the drug along the entire length of GIT(b) Prolonged their residence in the GIT and release(c) Release only at a specific drug(d) Very slow dissolution rateThis question was addressed to me in quiz.My enquiry is from Biopharmaceuticals in chapter Biopharmaceuticals of Drug Biotechnology
Answer» The correct option is (d) Very slow dissolution rate To explain: Dissolution controlled RELEASE system is easiest to DESIGN. The drug of such system may be inherently slow dissolution, such drugs ACT as natural prolonged release products. These drugs form slow DISSOLVING forms when it comes in contact with GI fluids. These drugs have HIGH aqueous solubility.
