Abstract Shellac is a natural polymer, which is used as enteric coating material in pharmaceutical applications. The major objective of the present study was to investigate the potential of shellac for other purposes, namely to provide moisture-protective and taste-masking coatings as well as extended-release matrix tablets. The efficiency of shellac to achieve moisture protection and taste masking was compared with that of hydroxypropyl methylcellulose (HPMC), which is most frequently used for… 
Effect of coating excipients on chemical stability of active coated tablets
Higher stability of triacetin systems over PEG systems was attributed to lower solubility and mobility of peliglitazar in HPMC compared with the PVA-based coating, while for the same plasticizer/detackifier, higher stability of H PMC over PVA, based on the overall stability for the film-forming polymer-plasticizer/ Detackifier combination.

Formulation and Development of Aqueous Film Coating for Moisture Protection of Hygroscopic Herniaria glabra L. Tablets
Objectives The present study aims to develop a moisture-protective coating solution and use it to film coat hygroscopic Herniaria glabra L. tablets. Materials and Methods Five coating formulations
An Update of Moisture Barrier Coating for Drug Delivery
Different strategies have been designed and developed to effectively decrease water vapor permeability and improve the moisture barrier function of the film and could potentially replace the current solvent and aqueous coatings.
Modulation of drug release kinetics of shellac-based matrix tablets by in-situ polymerization through annealing process.
Investigation of drug release from pellets coated with different shellac types
The Thai shellac stands out providing both gastric resistance at low CLs and fast drug release at high pH 6.8, and the intrinsic dissolution rate turned out to be a good indicator for the drug release behavior.
Taste masking of naproxen sodium granules by fluid-bed coating
An optimum ratio between naproxen sodium granules and Eudragit® E was found to be 1:1.576, where less naproxin sodium was released than the threshold bitter value and an appropriate taste masking for more than 5 min was guaranteed.
Influence of the inlet air temperature in a fluid bed coating process on drug release from shellac-coated pellets
Pellets coated at lower temperatures showed distinct cracks in the coating film resulting in a loss of the barrier function during dissolution testing, and these cracks were nonreversible by additional curing.
Quality Properties of Enteric-Coated Soft Capsule Using PEG as a Plasticizer
We investigated the applicability of polyethylene glycol (PEG) as a plasticizer in enteric-coated soft capsules based on determination of quality characteristics according to molecular weight and


Polymers with pH-Dependent Solubility: Possibility of Use in the Formulation of Gastroresistant and Controlled-Release Matrix Tablets
Polymers usually utilized for gastroresistant film coating of tablets or pellets such as cellulose acetate phthalate (CAP) and Eudragit L and S were used in the preparation of drug/polymer matrix tablets to verify if the tablets possessed gastroresistant or controlled-release characteristics.
Taste masked pharmaceutical particles
PURPOSE: Taste masked particles containing a polymeric film as a mixture of an enteric polymer and an insoluble film-forming polymer are provided. Therefore, the masked particles can be used for the
Use of hydroxypropyl methylcellulose acetate succinate in an enteric polymer matrix to design controlled-release tablets of amoxicillin trihydrate.
A controlled-release table of amoxicillin trihydrate developed by use of a matrix formulation based on the enteric polymer hydroxypropyl methylcellulose acetate succinate showed a promising sustained-release effect in vitro when a variable-pH-shift dissolution procedure was used, but single-dose studies showed that the tablets had a relative bioavailability of only 64.4%.
The Influence of Excipients on the Stability of the Moisture Sensitive Drugs Aspirin and Niacinamide: Comparison of Tablets Containing Lactose Monohydrate with Tablets Containing Anhydrous Lactose
The purpose of this study is to test the hypothesis that in tablet formulations, moisture-sensitive drugs formulated with lactose monohydrate have the same stability as formulations containing
In vitro/in vivo evaluation of two series of TA-5707F controlled release matrix tablets prepared with hydroxypropyl methyl cellulose derivatives with entero-soluble or gel-formation properties.
Two series of matrix tablets for the newly developed anti-histaminergic drug, TA-5707F, were prepared, and the H-2 and H-3 tablets were administered to humans; however, the plasma concentration profiles did not show sufficient duration time for either tablet.
The In Vitro and In Vivo Performance of Aqueous Bases Enteric Coats of Neutralised Hydroxypropyl Methyl Cellulose Phthalate
The failure of the neutralised HPMCP coating probably results from incomplete gastric conversion to its acidic form due to the majority of subjects having gastric pH values in excess of those stipulated in the compendial in vitro tests.
