Sustained release dosage forms are designed to release a drug in a predetermined fee by keeping a continuing drug level for a selected length of time with least Unintended effects. The basic rationale of sustained release drug delivery system optimizes the biopharmaceutical, pharmacokinetic and pharmacodynamics Homes of a drug in this type of way that its utility is maximized, aspect-outcomes are reduced and treatment on the sickness is accomplished.
Sustained release know-how is characterised from the gradual releasing of a particular material at a programmed level to provide the drug for a prolonged time frame.
