Coating and binding agent for oral or dermal pharmaceutical forms

   
   

The invention relates to a method for the production of a coating and excipient agent for oral or dermal dosage forms, consisting of (a) 35-98% by weight of a copolymer consisting of radically polymerized C1-C4 esters of acrylic or methacrylic acid and additional (meth)acrylate monomers having functional tertiary amino groups and (b) 1-50% by weight of a softener and 1-15% by weight of an emulgator with an HLB value of less than 14, wherein constituents (a), (b) and (c) are mixed with or without adding water and optionally adding a pharmaceutical active substance and other conventional additives and the coating and excipient agent is produced by melting, casing, spreading or spraying. The invention is characterized in that the copolymer (a) is applied in powder form with a mean particle size of 1-40 .mu.m.

A invenção relaciona-se a um método para a produção de um agente do revestimento e do excipient para formulários de dosage orais ou dermal, consistindo (a) em 35-98% pelo peso de um copolymer que consiste nos esters C1-C4 radical polimerizados do acrílico ou ácido methacrylic e adicional (os monomers do meth)acrylate que têm amino grupos tertiary funcionais e (b) 1-50% pelo peso de um softener e 1-15% pelo peso de um emulgator com um valor de HLB menos de de 14, wherein os constituents (a), (b) e (c) são misturados com ou sem adicionar a água e opcionalmente adicionar uma substância ativa pharmaceutical e outros aditivos convencionais e o agente do revestimento e do excipient é produzido derretendo, encaixotando, espalhar ou pulverizar. A invenção é caracterizada que o copolymer (a) está aplicado no formulário do pó com um tamanho de partícula médio do mu.m 1-40.
