Info

Types of microcapsules1. Mononuclear (core-shell) microcapsules contain the shell around the core.2. Polynuclear capsules have many cores enclosed within the shell.3. Matrix encapsulation in which the core material is distributed homogeneously into the shell material.
Formulation considerations1. Core material: The core material is defined as the specific material to be coated whether it can be asolid or liquid. The solid core can be the active ingredient, stabilizers, diluents, excipients, release rateretardants whereas liquid core include the dissolved materials.2. Coating material: Coating materials are defined as a layer of substance covered over the core forproduction of the drug. The coating material should possess properties such as• It should have controlled release under specific conditions, soluble in aqueous media/solvent.• It should possess sufficient properties such as flexibility, strength, impermeability, stability and opticalproperties.• It should be chemically compatible with the core and non-reactive.• It should be capable of forming a film.
