  • Publication number: 20200345637
    Abstract: This disclosure relates to aqueous suspension formulations of multi-target inhibitors. These formulations can be locally administered to target tissues such as eyes, prostate, that may be solved by the present disclosure are to (1) provide an injectable dosage form that allows direct delivery of a multi-target inhibitor to the proximity of the diseased tissue, (2) be compatible with the tissue of the site of administration, (3) form a drug reservoir at the administration site to allow prolonged supply of the drug to the diseased tissue, and thus reduce dosing frequency, (4) the release rate of the drug from the reservoir is such that above therapeutic level of the drug in the diseased tissue is achievable, (5) have physicochemical properties that are suitable for clinical uses, (6) be terminally sterilizable so that safety risk due to contamination of micro-organisms can be minimized, and (7) have a stability profile suitable for long term storage and distribution.

  • Publication number: 20030165555
    Abstract: Methods and compositions are taught that may be used to administer specific bioactive polypeptides, known as T20 and T1249 to a patient, e.g., as a method of treating a disease or disease state. In particular, the invention teaches carrier hydrogel composition that contain (a) a polymer material and (b) an effective dose of T20, T1249 or a derivative thereof. The polymer materials used in the carrier hydrogel composition preferably have reverse gelation properties and exist as a liquid, aqueous solution at temperatures below physiological temperatures (e.g., below the body temperature of a patient) but form hydrogels under physiological conditions (e.g., at temperatures at or near the body temperature of a patient). The carrier hydrogel compositions may thus be administered to a patient by injection while they are in a liquid state. Upon administration the carrier hydrogel compositions then form hydrogels with the T20 and/or T1249 polypeptides embedded therein.

  • Patent number: 5981607
    Abstract: An eye drop composition for alleviation of dry eye related symptoms in dry eye patients and contact lens wearers includes an emulsion of a higher fatty acid glyceride, polysorbate 80 and an emulsion stabilizing amount of Pemulen.RTM. in water suitable for topical application to ocular tissue.

  • Patent number: 5585406
    Abstract: A nonirritating, nonionic detergent surfactant composition suitable for application to and cleaning of sensitive tissue, including periocular and ocular tissue, having a low cytotoxicity and high cleaning ability includes a principal nonionic surfactant and at least one auxiliary nonionic surfactant present in the surfactant composition in sufficient amounts to increase the cleaning ability of the principal non-ionic surfactant.

  • Patent number: 5550163
    Abstract: A method for reducing filtrate waste in a manufacturing process of a pharmaceutical product containing benzalkonium chloride as a preservative generally includes the steps of mixing the non-benzalkonium chloride components with benzalkonium chloride to formulate the product and thereafter sterilizing the product by passing same through a microfiltration membrane. In processes in which the product has a time dependent benzalkonium chloride content due to benzalkonium chloride adsorption on a microfiltration membrane, an amount of benzalkonium chloride wasted can be reduced by maintaining a selected temperature of the microfiltration membrane and the product therein.

  • Patent number: 5474979
    Abstract: A pharmaceutical composition is disclosed in the form of a nonirritating emulsion which includes at least one cyclosporin in admixture with a higher fatty acid glyceride and polysorbate 80. More particularly, the cyclosporin may be cyclosporin A and the higher fatty acid glyceride may be castor oil. Composition has been found to be of a high comfort level and low irritation potential suitable for delivery of medications to sensitive areas such as ocular tissues. In addition, the composition has stability for up to nine months without crystallization of cyclosporin.

  • Patent number: 5252318
    Abstract: Reversibly gelling aqueous compositions are disclosed which undergo significant changes in viscosity in response to substantially simultaneous changes in both temperature and pH. The compositions are formed of relatively low concentrations of a stable combination of at least one pH-sensitive reversibly gelling polymer and at least one temperature-sensitive reversibly gelling polymer. The compositions can be formulated to exhibit a sol-gel transition over a wide range of conditions and viscosities and may be modified to incorporate a pharmaceutical compound for utilization as droppable or injectable drug delivery systems which will gel following administration to a physiological system for the sustained delivery of such pharmaceutical compounds.

  • Patent number: 4606940
    Abstract: Process for the formation and the simultaneous encapsulation of small particles of a compound from solution which comprises:(a) dissolving said compound in a first solvent;(b) preparing a solution of encapsulating material and an electrolyte in a second solvent which is miscible with the first solvent and in which the compound to be encapsulated is more or less insoluble, in an amount which is effective, but present in an amount just insufficient to cause coacervation of the encapsulating material without interacting with it;(c) mixing the solutions from step (a) and (b) while stirring to cause the concurrent precipitation of the compound as small particles and formation of a coacervate of the encapsulating material; and(d) gelling the encapsulating material.
