Crystallization Point Depressant Or Cold Stabilizer Containing Patents (Class 514/971)
  • Patent number: 8048927
    Abstract: The present invention provides methods for treating and preventing benign breast disease by administering 4-hydroxy tamoxifen to a patient. When percutaneously administered to a patient's breasts, 4-hydroxy tamoxifen concentrates locally, and exerts an anti-estrogenic effect. In patients with benign breast disease, this effect induces disease regression. In patients at risk for developing breast cancer, the anti-estrogenic effect prevents formation of benign breast conditions that can lead to cancer.

    Abstract: The present invention relates to a novel aqueous flowable composition of fenazaquin. It was found that conventional aqueous flowable formulations resulted in a product that lost miticidal activity during storage. The low miticidal activity was found to be due to an unacceptable level of particle size growth during storage. It has been found that an aqueous flowable fenazaquin formulation of satisfactory particle size stability can be made when a higher than normal concentration of sodium naphthalene formaldehyde condensate dispersant is utilized in the formulation.

    Abstract: Small unilamellar liposomes (d<600 nm) comprising an unsaturated phosphatidylethanolamine (PE) such as dioleoyl PE (DOPE) and a fatty acid such as oleic acid (OA) are stabilized by adding to a freshly prepared liposome suspension, an amphipile which has a high tendency to form micelles. Examples are shown for the following micelle-forming amphiphiles: lysophospholipide, gangliosides (GM.sub.1 and GTlb), sulfatide, synthetic glycopholipids such as sialo-lactosyl phosphatidylethanolamine, liopohilic drugs such as cytosine arabinoside diphosphate diacyglycerol, and proteins such as cytochrome b.sub.5, human high density lipoprotein (HDL), and human glycophorin A. The stabilized liposomes are resistant to the lytic action of albumin, the major blood component which causes the lysis of this type of liposome. Prior to the present invention, liposomes comprising PE and OA were typically stabilized by the incorporation of cholesterol.

  • Patent number: 4806343
    Abstract: A method of protecting soluble proteins such that their biological activity is preserved after freezing by exposing the protein to a carbohydrate and transition metal ion prior to freezing. The protected protein can then be thawed or lyophilized and rehydrated without denaturation of impairment of the protein's biological activity. The protein is preferably exposed to the carbohydrate by placing it in a 25-100 mM aqueous solution of carbohydrate and 2 mM Z.sup.+2. This method is especially effective in preserving the biological activity of fragile proteins such as the enzyme phosphofructokinase. The present method can be used to preserve pharmaceutically useful proteins in a frozen or freeze-dried form for storage and distribution. The treated protein can be thawed or rehydrated and administered directly to a user without removing the cryoprotectant since the carbohydrates and trace amounts of many transition metal ions are nontoxic.

  • Patent number: 4727064
    Abstract: The invention comprises pharmaceutical preparations consisting generally of a drug with a substantially low water solubility and an amorphous, water-soluble cyclodextrin-based mixtures. In these preparations a stable amorphous state can be achieved. This improves the dissolution properties of the drug and hence its absorption by the body. The required cyclodextrin-based mixtures were prepared from .alpha.-, .beta.-, or .gamma.-cyclodextrin which were rendered amorphous through non-selective alkylation. The alkylation agents suitable for that purposes are exemplified by propylene oxide, glycidol, iodoacetamide, chloroacetate, or 2-diethylaminoethylchloride; their reactions with cyclodextrins were performed in a manner to yield mixtures containing many components, a circumstance which effectively prevents crystallization processes within the above pharmaceutical preparation.
