Abstract: pH sensitive, reversible gelling erodible drug delivery compositions and methods for their production are disclosed. The compositions are liquid solutions of poly(methylvinylether/maleic acid) having pharmaceutical compounds incorporated therein. The poly(methylvinylether/maleic acid) solutions increase in viscosity with increases in pH. Thus, when the compositions are formulated at a pH lower than physiological pH's, and then delivered to a target physiological site, the liquid solution becomes viscous and adheres to the tissue for a length sufficient to provide prolonged bioavailability of the pharmaceutical compound.

Abstract: A composition of three compounds, (E,E)-10,12-tetradecadien-1-ol acetate (I), (Z)-11-tetradecen-1-ol acetate (II), and (Z)-9-tetradecen-1-ol acetate (III), in a weight ratio of about 100:18:4 (I:II:III) is a highly effective sex attractant (pheromone) for the male mint root borer. The composition demonstrates biological activity toward mint root borer males comparable to or greater than that of the mint root borer moth females. By attracting adult males to field traps, the composition provides a means for detecting, monitoring, and controlling this agricultural pest.

Abstract: Quick miosis with 24 hour control of intraocular pressure of patients undergoing extracapsular cataract extraction surgery is achieved by applying to the eyes of the patient during surgery acetylcholine as a first miotic agent and carbachol as a second miotic agent. Acetylcholine provides quick miosis while carbachol enhances the miotic effect while providing post-surgery control of intraocular pressure. The two miotic agents can be dissolved in a common saline carrier. The two agents can be combined in a unit dosage package by disposing acetylcholine in powder form in a first compartment and a solution of carbachol in a second compartment. The combined miotic agent of the invention is especially useful when substances which raise IOP such as viscoelastic agents are used during ocular surgery and/or with sensitive patients who enter the surgery with elevated pressure such as those suffering from glaucoma.

Abstract: A process for producing a slow-release powder which permit various active ingredients such as perfumes, insect control agents, rust inhibitors, mold inhibitors and antibacterial agents to be slowly released over a prolonged time, the process comprising the steps of mixing a long-chain compound with the ingredients, mixing the resulting mixture with urea, and exposing the resulting urea adduct to radiation.

Abstract: This invention relates to an analgesic composition and more particularly, to a directly dry compressible composition comprising at least about 70% by dry weight of the composition of acetaminophen and a metal carboxymethyl starch present in an amount sufficient for it to function both as a binder and as a disintegrating agent.

Abstract: Perfluoro derivatives of dimethyladamantane; tributylamine; dihexylether; 1-bromooctane; and tetradecahydrophenanthrene, for example, are rendered dispersable colloidally in water or other polar media without the aid of an emulsifying agent by melt spinning a mixture of the compound with a sugar. Thus, a family of new colloidal perfluoro compounds are produced.

Abstract: A composition and a method for coating a wound is described. The composition consists of a mixture of 20 parts by weight of polyether polyurethane resin pellets being dissolved in about 80 parts by weight of tetrahydrofuran thereafter mixing the solution in order to provide complete mixing in an air tight container. The composition then being applied to a wound to form a tough but elastic wound coating to promote healing of animal tissue.

Abstract: A penetrable, epoxy resin composition is disclosed which comprises: a liquid, epoxy resin mixture containing a glycidyl ether of bisphenol having an epoxy equivalent of 158-270 and a flexible epoxy resin; a curing agent capable of reacting with the epoxy resin mixture when heated to a curing temperature; an inert organic solvent which does not react with the epoxy resin mixture, which is capable of dissolving the curing agent and which has a boiling point lower than the curing temperature; and an inorganic filler having an average particle size of 0.1-5 .mu.m.

Abstract: Compressed-molded preparations are disclosed. In the preparation coated granules of a pharmaceutical composition are compressed and molded together with non-coated component(s) containing 10% or more by weight of non-swelling polymers. According to the preparation there is little breakdown of the coating of coated granules at the time of compressing and molding, and the rate of disintegration, and in turn, the release rate of the pharmaceutical component, can be freely controlled or modulated.

Abstract: What is described herein is solution polymerization in acetone solvent of a monomer mixture of maleic anhydride, vinyl acetate and isobornyl acrylate or methacrylate.

Abstract: Ophthalmic pharmaceutical compositions useful in controlling elevated intraocular pressure associated with glaucoma and ocular hypertension are described. The compositions comprise a combination of a beta-blocker to reduce the production of aqueous humor and carbachol to enhance the outflow of aqueous humor. A method of controlling elevated intraocular pressure with those compositions is also described.

Abstract: A particulate carrier for airborne suspensions of an active agent. The carrier is formed in situ by contacting a spray containing ammonia, a monoalkylamine or dialkylamine with a spray containing acetic acid and/or sulfur dioxide.

Abstract: An emulsion containing a substantially water resistant film-forming copolymer phase and iodine is claimed. The polymer-in-water emulsion forms a film that is a substantially fluid resistant, low tack, flexible film which adheres to skin and releases iodine to skin. The addition of iodate to emulsions having such a film-forming copolymer phase and iodine further enhances stability of the emulsion.
