This invention relates to a method of treating Major depressive disorder by orally administering to a subject a composition containing a Radix Polygalae (Polygala tenuifolia Willd) extract (PDC-1421). A solid dosage form of PDC-1421 can be prepared into the gelatin capsule. The oral administration of PDC-1421 in healthy volunteers was safe and well-tolerated for the daily dose from 380 mg to 3800 mg. The composition can be administered chronically over at least 25 days; the daily dose is administered once per day, twice per day, or three times per day, wherein each dose is 380-760 mg of the botanical extraction.

Provided herein are methods of treating multiple sclerosis with a fumarate, wherein the fumarate is a dialkyl fumarate, a monoalkyl fumarate, a combination of a dialkyl fumarate and a monoalkyl fumarate, a prodrug of monoalkyl fumarate, a deuterated form of any of the foregoing, or a pharmaceutically acceptable salt, clathrate, solvate, tautomer, or stereoisomer of any of the foregoing, or a combination of any of the foregoing. The methods provided herein improve the safety of treatment by informing and monitoring patients undergoing treatment regarding progressive multifocal leukoencephalopathy, and/or by monitoring lymphocyte count.

The present invention provides compounds which are selective allosteric inhibitors of T790M and C797S containing EGFR mutants, their manufacture, pharmaceutical compositions containing them and their use as therapeutically active substances.

The present invention relates to stable oral composition comprising linaclotide or its pharmaceutically acceptable salts, complexes, polymorphs, hydrates, solvates, enantiomers or racemates, process of preparation thereof and methods of using the same.

The present invention relates to a pharmaceutical composition including (i) as a major ingredient, a novel 5-{4-(Aminosulfonyl)phenyl}-2,2-dimethyl-4-(3-fluorophenyl)-3(2H)-furanone compound (Formula 1) or a pharmaceutically acceptable salt thereof, which has a crystalline form A or G, or a mixed form thereof and has a 50% volume particle diameter (d.sub.(0.5)) of 3 μm to 9 μm and a 90% volume particle diameter (d.sub.(0.9)) of 10 μm to 50 μm, (ii) a pharmaceutically acceptable diluent, and (iii) a pharmaceutically acceptable lubricant. The pharmaceutical composition of the present invention has the advantages of good stability, high dissolution rate, improved content uniformity, and excellent pharmacokinetic properties. Due to these advantages, as a non-steroidal anti-inflammatory drug, the pharmaceutical composition of the present invention may be effective in treating inflammation or pain.

A method for treating influenza is described. The disclosed method generally involves administering an effective amount of a compound, for example baloxavir marboxil, to a subject having influenza, where the compound is administered initially at least about 48 hours after an onset of influenza. Generally, the effective amount is sufficient to alleviate a symptom of influenza in the subject as compared to a symptom that the subject has when the compound is first administered to the subject.

A composition of substituted crotonamide pharmaceutical and a preparation method therefor. The pharmaceutical composition comprises 5-50 parts of (E)-N-(3-cyano-7-ethoxy-4-(3-ethynylphenylamino)quinolin-6-yl)-4-(dimethylamino)but-2-enamide maleate, 40-120 parts of a filler, 2-20 parts of a disintegrant, 0-6 parts of an adhesive, and 0.5-5 parts of a lubricant. The filler is selected from carbohydrates.

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.
