This doc discusses oral sustained and controlled release dosage kinds. It starts having an introduction and overview of rationality in planning sustained release drug formulations. It defines sustained release as formulations that consistently release medication more than an extended period after an individual dose to realize prolonged therapeutic outcomes.

This doc discusses differing kinds of controlled drug delivery systems. It classifies systems as amount preprogrammed, activation modulated, or responses regulated. Level preprogrammed systems are more broken down into polymer membrane permeation controlled systems, polymer matrix diffusion controlled systems, and microreservoir partition controlled systems.

Oakwood Labs offers a a single-quit shop to help all phases of long acting injectable (LAI) enhancement. Our sustained release microsphere technologies provides a personalized release get more info profile to accommodate your challenge's particular requirements.

Sustained release and controlled release drug delivery systems goal to keep up therapeutic drug levels in your body in excess of an extended length of time when compared to rapid release formulations. They work to release medication within a controlled vogue just after a single dose administration.
