Abstract

Optimizing Oral Controlled Release Drug Delivery Systems Using Experimental Designs

Highlights

  • The use of optimization techniques employing design of experiments (DoE), permeated the field of pharmaceutical product/process development around four decades ago

  • The number of optimization studies would be much higher in the drug industry, where DoE methods are applied much more frequently

  • Many more endeavors have to be undertaken to highlight the enormous benefits of these techniques before this can happen as a global trend

Summary

Introduction

The use of optimization techniques employing design of experiments (DoE), permeated the field of pharmaceutical product/process development around four decades ago. The controlled release drug delivery systems for oral use are solid dosage forms, based upon the mechanism of diffusion, dissolution, or a blend of both to control the release rate of drug. These include reservoir devices wherein a polymeric membrane surrounds a drug core and matrix devices wherein the dissolved or dispersed drug is distributed uniformly in an inert polymeric matrix.
