Poly(methacrylic acid-methyl methacrylate, 1:2) (Eudragit S) is a commonly used pH-responsive polymer that can facilitate delivery to the ileo-colonic region of the gastrointestinal tract. Different plasticizers have been used to reduce the

tough coating whereas low molecular weight PEG's are mainly used as plasticizers which prevent the film coat from becoming too brittle (12). Plasticizers cause a decrease in both the modulus of elasticity and the glass transition temperature of the polymer (13). Plasticizers could be released from die film and contaminate the drug.

Are polymeric drug delivery systems plasticizers?
Plasticizer as minor component of polymeric drug delivery systems has not been strictly defined. Even liquid drugs or liquids with a potential pharmacodynamic effect can serve as plasticizers. As well structural water in the hydrophilic polymer seems to be an internal plasticizer of the polymeric drug delivery systems.
Why are plasticizers added to pharmaceutical polymers?
Plasticizers are added to pharmaceutical polymers intending to ease the thermal workability, modifying the drug release from polymeric systems and improving the mechanical properties and surface properties of the dosage form (Felton, 2007; Lin et al., 2000; Wang et al., 1997; Wu & McGinity, 1999; Zhu et al., 2002).
Which polymers are plasticized with hygroscopic plasticizing effect?
The polymers plasticized with hygroscopic plasticizing effect. The thermoplastic starch is a material interesting for the use in pharmacy. It is p roduced by native granules and 2 0 % to 50 % glycerol. T his implantation. In the temperatures of 150 to 180 °C the produced. Glycerol and xylitol are important plasticizers
Does plasticizer accelerated polymers?
plasticizer, PEG, was added to the polymers. It was degradation-controlled phase. The plasticizer accelerated polymer. The plasticizer dep ressed the burst effect for controlled phase. For the PLLGA 80/20, however, the Table. List of plasticized polymers reviewed in presented cha pter risk. This leaching effect of Plasticizer is dependent on
Which substances were used as plasticizers?
Oily, waxy, or fatty substances were applied as plasticizers. Other invention relates to an oral pulse release comprising a polymer micromatrix, a first active ingredient distributed substantially uniformly within polymer micromatrix and a second active ingredient deposited on the surface of the polymer matrix (Gadre et al., 2006).
What is a plasticizer in chemistry?
ABSTRACT A plasticizer is a substance the addition of which to another material makes that material softer and more flexible. Most often plasticizers are materials which, when added to a polymer, cause an increase in the flexibility and workability, brought about by a decrease in the glass-transition temperature of the polymer.
