  • Publication number: 20110009836
    Abstract: The present application discloses a pharmaceutical delivery system for delivering a desired amount of liquid in the form of droplets. The pharmaceutical delivery system comprises a container having resilient compressible walls of uniform thickness, an elongated neck, and a valveless dropper tip. The pharmaceutical delivery system dispenses liquid through an outlet orifice in the valveless dropper tip in a drop by drop manner, producing droplets of substantially uniform volume independent of the amount of pressure applied on the container.

  • Publication number: 20090011014
    Abstract: Disclosed is a pharmaceutical sustained release tablet for oral administration of a drug which is made of a compressed blend of at least three dry powders including a powder of a drug, a powder of a sustained release matrix for the drug, and a powder of at least one electrolyte. The sustained release matrix consisting of an un-cross-linked high amylose starch wherein the high amylose is substituted by at least one organic substituent comprising at least one carboxyl group. This organic substituent is preferably a carboxyalkyl having 2 to 4 carbon atoms, its salt or mixture thereof. This tablet has the advantage of having an improved integrity.

  • Patent number: 5989589
    Abstract: Cross-linked cellulose is an excellent binder disintegrant that can be used in the preparation of pharmaceutical tablets. The tablets that are so prepared are made of a compressed mixture of a powder of a pharmaceutically active ingredient with a powder of a pharmaceutical excipient including a pharmaceutically acceptable form of cross-linked cellulose in an amount up to 35% by weight with respect to the total weight of the tablet. The cross-linked cellulose is prepared by cross-linking microcrystalline or fibrous cellulose with a cross-linking agent such as epichlorhydrin in a relative amount of 2 to 50 g of cross-linking agent per 100 g of cellulose. Tests have proved that cross-linked cellulose is very easy to synthetise and has excellent binding/disintegrating properties that are function of the cross-linking degree. At low cross-linking degree, cross-linked cellulose is more a binder than a disintegrant whereas at high cross-linking degree, it is more a disintegrant than a binder.

  • Patent number: 5879707
    Abstract: A pharmaceutical sustained release tablet for oral administration is made of a compressed blend of at least two dry powders including a powder of a pharmaceutical drug and a powder of a sustained release matrix for the drug. The sustained release matrix is made of substituted amylose prepared by reacting, in a basic medium, amylose with an organic substituent having a reactive function that reacts with the hydroxy groups of the amylose molecule. This substituent is preferably an epoxy or halogen alkane or alcohol with such a matrix controlled and sustained release of a drug are achieved with a remarkable close-to-linear profile and a release time of from 9 to 20 hours.
