This information can be used by industry as an aid in developing drug products. Particle size distribution Particle size distribution was determined using a nest of standard sieves 60, 85,and The sieves were agitated on a rotap sieve shaker International Combustion Ltd.

From the percentage weight of granules retained on each sieve, the mean granule diameter was calculated [ 11 ]. Dilution potential study Dilution potential is the amount of poorly compressible drug that can be satisfactorily compressed into a tablet.

Acetaminophen and metformin were taken as model drugs for the evaluation of dilution potential. Taste masking is important in the development of pediatric formulations and dosage forms like rapidly disintegrating tablets containing bitter drugs.

One mechanism of taste masking is to prevent dissolution of the drug in the mouth and contacting the taste buds, and only releasing drug in the stomach or beyond in the gastrointestinal tract.

A newly available methyl methacrylate diethylaminoethyl methacrylate 6: The co-polymer being pH-sensitive, effectively prevents drug dissolution under neutral conditions in the saliva, with immediate release under acidic iig limits for excipients of the stomach [20].

Another example is the application of copolymers based on dimethylaminoethyl methacrylate, butyl methacrylate, iig limits for excipients methyl methacrylate for taste masking by interacting complementary ionic groups. The taste masked product is formed by either interacting a cationic drug with an anionic methacrylate polymer or interacting an anionic drug with a cationic methacrylate polymer.

Randale et al demonstrated this in the preparation of rapidly disintegrating tablets containing taste masked metoclopramide [21].

Metoclopramide HCl was complexed with aminoalkyl methacrylate copolymer in different ratios by the extrusion—precipitation. Drug—polymer complexes were tested for drug iig limits for excipients, in vitro taste in simulated salivary fluid SSF of pH 6.

In that study, the complex having drug—polymer ratio of 1: The drug-polymer complexes exhibited considerable taste masking with the degree of bitterness below threshold value 0.

Biologics Recent advances in biologics are focused primarily on parenteral routes of administration. Materials have been investigated for greater stabilization in vitro and in vivoreduced frequency of administration, achievement of high doses and improved manufacturability of biologic iig limits for excipients such as maintaining protein activity on scale-up.

Major classes of delivery systems used in biologics formulation include microspheres PLGA-based, chitosan-basedliposomes PEGylated lipids and hydrogels modified dextran and starch-based. An emerging class of materials to be considered iig limits for excipients biologics is the dendrimer-based polymers.

Dendrimers are highly monodisperse, unlike the polydispersity of traditional polymers.

Dendrimers are highly stable structures since they are covalently fixed 3D structures. Furthermore, they have properties that make them amenable for targeting. For example, dendrimers are polyvalent, and they have surface groups that can be engineered to iig limits for excipients pH- or polarity-related changes in conformations.
