  • Patent number: 6642205
    Abstract: A pharmaceutical compound and a process for making the compound is provided where the compound includes a therapeutic agent, a spacer and a galactose, the spacer being covalently linked to the therapeutic agent at a first site on the spacer and covalently linked to the galactose by an ether bond at a second site on the spacer to form a conjugate. The conjugate may be used to treat a subject suffering from a medical condition, so as to reduce the side effects associated with the therapeutic agent by administering an effective dose of the conjugate to the subject so that the side effects in the subject are less then they would have been with the unconjugated therapeutic agent.

  • Patent number: 6610317
    Abstract: Paclitaxel is provided in a porous matrix form, which allows the drug to be formulated without Cremophor and administered as a bolus. The paclitaxel matrices preferably are made using a process that includes (i) dissolving paclitaxel in a volatile solvent to form a paclitaxel solution, (ii) combining at least one pore forming agent with the paclitaxel solution to form an emulsion, suspension, or second solution, and (iii) removing the volatile solvent and pore forming agent from the emulsion, suspension, or second solution to yield the porous matrix of paclitaxel. The pore forming agent can be either a volatile liquid that is immiscible with the paclitaxel solvent or a volatile solid compound, preferably a volatile salt. In a preferred embodiment, spray drying is used to remove the solvents and the pore forming agent.

  • Patent number: 6572890
    Abstract: The present invention provides an osmotic device containing controlled release venlafaxine in the core in combination with an anti-psychotic agent in a rapid release external coat. A wide range of anti-psychotic agents can be used in this device. Particular embodiments of the invention provide osmotic devices having predetermined release profiles. One embodiment of the osmotic device includes an external coat that has been spray-coated rather compression-coated onto the device. The device with spray-coated external core is smaller and easier to swallow than the similar device having a compression-coated external coat. The device is useful for the treatment of depression, anxiety or psychosis related disorders.

  • Patent number: 6544542
    Abstract: The object of the present invention is to provide a pharmaceutical composition optimized for the administration of a drug, particularly a drug which is only sparingly soluble in water, by way of inhalation. The present invention is a fat emulsion for inhalational administration, or a lyophilized composition thereof, which is an o/w fat emulsion comprising fat emulsion particles essentially composed of an oil component, an emulsifying agent and a drug as dispersed in water, characterized in that the average particle diameter of said fat emulsion particles lies within the range of 5˜100 nm. With the aid of a suitable inhaler, the inhalant of the invention readily yields a mist of aerosol particles fine enough to reach the alveolus; the inhalant is well amenable to size control of the aerosol particles.
