Abstract
La liberación retardada de un fármaco al colon se logra de una formulación de liberación retardada que comprende un núcleo y un recubrimiento para el núcleo. El núcleo comprende un fármaco y un recubrimiento que comprende una capa interior y una capa exterior. La capa exterior comprende una mezcla de un primer material polimérico que es susceptible a ataques por parte de la bacteria colónica, y un segundo material polimérico que tiene un umbral de pH a aproximadamente pH 5 o más alto. La capa interior comprende un tercer material polimérico que es soluble en el fluido intestinal o en el fluido gastrointestinal, tal tercer material polimérico se selecciona de ácido policarboxílico al menos parcialmente neutralizado y un polímero no iónico. En modalidades en donde el tercer material polimérico es un polímero no iónico, la capa interior comprende al menos un agente regulador del pH y una base. Las ventajas de las formulaciones de acuerdo con la presente invención incluyen la liberación acelerada del fármaco cuando se expone a condiciones colónicas y la reducción o eliminación del efecto de los alimentos y/o alcohol en la liberación del fármaco después de la administración.Delayed release of a drug to the colon is achieved from a delayed release formulation comprising a core and a coating for the core. The core comprises a drug and a coating comprising an inner layer and an outer layer. The outer layer comprises a mixture of a first polymeric material that is susceptible to attack by colonic bacteria, and a second polymeric material that has a pH threshold at about pH 5 or higher. The inner layer comprises a third polymeric material that is soluble in intestinal fluid or gastrointestinal fluid, such third polymeric material is selected from at least partially neutralized polycarboxylic acid and a non-ionic polymer. In embodiments where the third polymeric material is a nonionic polymer, the inner layer comprises at least one pH regulating agent and a base. Advantages of formulations according to the present invention include accelerated drug release when exposed to colonic conditions and reduction or elimination of the effect of food and / or alcohol on drug release after administration.
