The present invention provides a method for safe and efficacious administration of esketamine.

The present invention relates to formulations comprising dolutegravir or a pharmaceutically acceptable salt thereof, abacavir or a pharmaceutically acceptable salt thereof and lamivudine, processes for making such formulations, and the use of such formulations in the treatment of HIV infection, in particular in the treatment of HIV infection in pediatric patients.

The present invention relates to a pharmaceutical formulation comprising the drug 4-[3-(4-cyclopropanecarbonyl-piperazine-1-carbonyl)-4-fluoro-benzyl]-2H-phthalazin-1-one in a solid dispersion with a matrix polymer that exhibits low hygroscopicity and high softening temperature, such as copovidone. The invention also relates to a daily pharmaceutical dose of the drug provided by such a formulation. In addition, the invention relates to the use of a matrix polymer that exhibits low hygroscopicity and high softening temperature in solid dispersion with 4-[3-(4-cyclopropanecarbonyl-piperazine-1-carbonyl)-4-fluoro-benzyl]-2H-phthalazin-1-one for increasing the bioavailability of the drug.

The present disclosure relates to an oral eliglustat transmucosal delivery system. More specifically, the present disclosure is related to an oral transmucosal dosage form comprising a non-disintegrating solid mass comprising (a) a hydrophilic viscosity modifying agent selected from a natural or a synthetic gum with a molecular weight of 10,000 Daltons or greater, (b) a low molecular weight water soluble component with a molecular weight of less than 10,000 Daltons and (c) not more than 70 mg eliglustat, wherein the dosage form is 500 mg or less and provides an oral cavity residence time of at least about 5 minutes, and wherein the dosage form generates a microenvironment inside the oral cavity exhibiting a thixotropic behavior with viscosities of at least 50 poises at 1/sec shear rate and at least 10 poises at 10/sec share rate. The dosage forms of as described herein have at least 30% dose reduction as compared to commercially available eliglustat capsules. In addition, unlike the dosing prerequisite for commercially available eliglustat capsules, the oral eliglustat transmucosal dosage form described herein can be administered to patients with Gaucher disease type 1 without pre-determination of patients' CYP2D6 genotype.

Many drug therapies could be greatly improved by dosage forms that reside in the stomach for prolonged time and release the drug slowly. In this specification, therefore, a gastroretentive structured dosage form is disclosed. The dosage form comprises a solid core having at least a fluid-absorptive first excipient. The dosage form further comprises a semi-permeable surface layer substantially encapsulating said solid core. The surface layer comprises at least a mechanically strengthening second excipient. Upon ingestion, the surface layer-supported solid core expands with physiological fluid absorption and remains in the stomach for prolonged time.

The present invention relates to an oral pharmaceutical composition comprising a carbamate compound of chemical formula 1, an isomer thereof, or a pharmaceutically acceptable salt, solvate, or hydrate thereof as an active ingredient, and a preparation method therefor.

Disclosed are a composition containing an aromatic heterocyclic compound in an amorphous form, and a preparation method therefore and a use thereof. Specifically, disclosed is a composition containing a compound of Formula (1) and a carrier, wherein the compound of formula (1) is in an amorphous form. The composition shows valuable properties in terms of in vivo absorption and bioavailability, and has the advantages of rapid absorption and high bioavailability, etc.

The invention discloses a cannabinoid nano-micelle preparation and a preparation method thereof. The cannabinoid nano-micelle preparation includes cannabinoid and an amphiphilic polymer, wherein the content of the cannabinoid is 1-40% by weight, the content of the amphiphilic polymer is 1-99%, and the preparation method includes the following steps: (1) preparing a cannabinoid nano-micelle solution from cannabinoid and an amphiphilic polymer; (2) drying the micellar solution obtained in the step (1) to obtain cannabinoid nano-micelle powder; and (3) preparing the cannabinoid nano-micelle powder obtained in the step (2) into the cannabinoid nano-micelle preparation. The cannabinoid nano-micelle preparation is high in effective component wrapping rate and transfer rate, high in drug loading capacity and high in stability, and a novel normal-temperature self-assembly technology is adopted, so that an active component cannabinoid is prevented from being degraded and discolored at high temperature; the bioavailability of the active ingredient is high, and a single dose can be reduced. Especially, a dry powder inhalant is high in in-vitro deposition rate and quick in inhalation effect, and can provide continuous and stable blood concentration.

The present invention relates to pharmaceutical compositions comprising a solid dispersion of N-[2,4-Bis(1,1-dimethylethyl)-5-hydroxyphenyl]-1,4-dihydro-4-oxoquinoline-3-carboxamide, methods of manufacturing pharmaceutical compositions of the present invention, and methods of administering pharmaceutical compositions of the present invention.

Disclosed herein are pharmaceutical compositions having a mixture of at least one active agent and an ion exchange resin, such that the composition releases about 75% or more of the at least one active agent within about 1 hour as measured by in-vitro dissolution in a USP Apparatus 2 (paddle) at about 50 rpm in about 900 ml 0.1N HCl at about 37° C. and related methods. Also disclosed herein are pharmaceutical compositions having a mixture of a drug susceptible to abuse, a non-opioid analgesic and an ion exchange resin, the composition further including at least one gelling agent and related methods.
