A method of treating tachycardia while minimizing and/or controlling hypotension associated with such treatment includes administering a therapeutically effective amount of a pharmaceutical composition comprising the S-isomer of esmolol to a subject in need thereof.

Methods for treating tachycardia and/or controlling heart rate while minimizing and/or controlling hypotension

The present invention is concerned with delivering a pharmaceutical composition to the brain of a mammalian subject for treating brain diseases or disorders. The process includes the steps of: (i) providing a dispersion of the pharmaceutical composition as particles having an average particle size of from about 150 nm to about 100 microns, and (ii) administering the dispersion to the mammalian subject for delivery to the brain of a portion of the pharmaceutical composition by cells capable of reaching the brain. The dispersion of the pharmaceutical composition as particles, for example, can be phagocytized or adsorbed by the cells prior or subsequent to administration into the mammalian subject. The dispersion of the pharmaceutical composition can be administered to the central nervous system or the vascular system. After administration, the loaded cells transport the pharmaceutical composition as particles into the brain.

Method for delivering drugs to the brain

The present invention is concerned with delivering a pharmaceutical composition to a tissue target of a mammalian subject for treating brain diseases or disorders. The process includes the steps of: (i) providing a dispersion of the pharmaceutical composition as particles having an average particle size of from about 150 nm to about 100 microns, and (ii) administering the dispersion to the mammalian subject for delivery to the tissue target of a portion of the pharmaceutical composition by cells capable of reaching the tissue target. The dispersion of the pharmaceutical composition as particles, for example, can be phagocytized or adsorbed by the cells prior or subsequent to administration into the mammalian subject. The dispersion of the pharmaceutical composition can be administered to the central nervous system or the vascular system. After administration, the loaded cells transport the pharmaceutical composition as particles into the tissue target.

Method for delivering particulate drugs to tissues

A pharmaceutical composition comprising (S)-methyl-3-[4-(2-hydroxy-3-isopropylamino)propoxy]phenylpropionate in a concentration between about 75 mM and about 150 mM, which is substantially free of the R-isomer or pharmaceutically acceptable salt thereof, is provided. A method of treating a cardiac disorder is also provided and includes administering to a subject in need thereof a therapeutically effective amount of a pharmaceutical composition comprising (S)-methyl-3-[4-(2-hydroxy-3-isopropylamino)propoxy]phenylpropionate hydrochloride, wherein the (S)-methyl-3-[4-(2-hydroxy-3-isopropylamino)propoxy]phenylpropionate hydrochloride is present at a concentration between about 75 mM and about 150 mM and wherein the pharmaceutical composition is substantially free of (R)-methyl-3-[4-(2-hydroxy-3-isopropylamino)propoxy]phenylpropionate or pharmaceutically acceptable salt thereof.

The present invention provides a process for sterilizing a system, preferably a pharmaceutical preparation such as a dispersion of small particles or droplets of a pharmaceutically active compound using high pressure terminal sterilization techniques and products therefrom.

High-pressure sterilization to terminally sterilize pharmaceutical preparations and medical products

The present invention is concerned with a method of preparing and delivering small particles of a pharmaceutically active material to a mammalian subject for treating diseases or disorders. A preferred embodiment entails: (i) the collection of tissue cells from an animal donor, (ii) selective or non-selective growth of these cells in a cell culture medium to which is added solid particles of a therapeutically active compound, mostly free of a drug carrier (about 10% or less, by weight), and having an average particle size of less than about 100 microns, (iii) contacting the cells in the cell culture medium with the solid particles of therapeutically active compound causing the particles to be taken up by the cells into either the intracellular compartment of the cultured cells, attachment of the active compound as particles to the periphery of such cells, or a combination of intracellular uptake and attachment to the cell surface, (iv) optionally, isolation and/or resuspension of the cells prepared in steps i through iii, (v) administering the cells to the mammalian subject. The pharmaceutically active material can be administered intravenously, intramuscularly, subcutaneously, intradermally, intra-articularly, intrathecally, epidurally, intracerebrally, via buccal route, rectally, topically, transdermally, orally, intranasally, via pulmonary route, intraperitoneally, or combinations thereof. After administration, the loaded cells transport the pharmaceutical composition as particles.

Ex-vivo application of solid microparticulate therapeutic agents

The present invention relates to compositions of submicron- to micron-size particles of antimicrobial agents. More particularly the invention relates to a composition of an antimicrobial agent that renders the agent potent against organisms normally considered to be resistant to the agent. The composition comprises an aqueous suspension of submicron- to micron-size particles containing the agent coated with at least one surfactant selected from the group consisting of: ionic surfactants, non-ionic surfactants, biologically derived surfactants, and amino acids and their derivatives. The particles have a volume-weighted mean particle size of less than 5 &#x3bc;m as measured by laser diffractometry.

Method for treating infectious organisms normally considered to be resistant to an antimicrobial drug

Stable pharmaceutical formulations and methods of making same are provided. In a general embodiment, the present disclosure provides a method of making a stable pharmaceutical formulation comprising adding one or more vitrifying additives to an aqueous pharmaceutical solution to raise the glass transition temperature of the aqueous pharmaceutical solution. The aqueous pharmaceutical solution can be cooled to a temperature of about &#x2212;50&#xb0; C. to about &#x2212;10&#xb0; C. The vitrifying additive enhances the formation of a glass or amorphous solid of the aqueous pharmaceutical solution at cryogenic temperatures (&#x2212;50 to &#x2212;10&#xb0; C.), and the pharmaceutical formulation can be thawed to liquid form and administered to a mammalian subject.

Stable pharmaceutical formulations

The present invention is concerned with the formation of submicron particles of an antineoplastic agent, particularly paclitaxel, by precipitating the antineoplastic agent in an aqueous medium to form a pre-suspension followed by homogenization. Surfactants with phospholipids conjugated with a water soluble or hydrophilic polymer such as PEG are used as coating for the particles. The particles produced generally have an average particle size of less than about 1000 nm and are not rapidly soluble.

Method for preparing submicron particles of antineoplastic agents

A protein-compatible polymer blend made from a water-soluble polymer and a matrix polymer. The glass transition temperature of either the water-soluble polymer or the matrix polymer is greater than the application temperature, i.e., the temperature at which the protein-compatible polymer blend is being used.

Biomaterials with hydrophilic surfaces

Formulations of intravenous anesthetic propofol emulsions are provided which contain sufficiently low concentrations of soybean oil to produce a stable emulsion and simultaneously provide reduced nutrients, which inhibit microbial growth thereby providing protection against accidental microbial contamination during long-term IV infusions. In addition to the inhibition of microbial growth due to a reduction of nutrients, the formulation exhibits unanticipated additional microbial inhibition due to an increased availability of propofol. The low concentration of soybean oil also provides a formulation that reduces the chances of fat overload when administered over an extended period of time to chronically ill patients.
