Provided herein are solid dispersions comprising rifaximin and pharmaceutical compositions and uses thereof.

The invention relates to a compound of formula (I) ##STR00001##
wherein A.sup.1, A.sup.2 and R.sup.1-R.sup.5 are as defined in the description and in the claims. The compound of formula (I) can be used as a medicament.

Disclosed herein are solid oral dosage formulations comprising sodium sulfate, magnesium sulfate, and potassium chloride for inducing purgation of the colon of a subject. Furthermore, the disclosed compositions and formulations are useful to cleanse the colon when administered in sufficient quantities. Methods for inducing purgation of the colon and for cleansing the colon are also disclosed.

The present invention relates to pharmaceutical dosage forms, for example to a tamper resistant dosage form including an opioid analgesic, and processes of manufacture, uses, and methods of treatment thereof.

The present invention relates to a modified-release composition comprising orlistat and acarbose, comprising individually distinct parts with different release patterns: a) a first part, G1, comprising from about 5 to about 70% w/w of the total dose of acarbose, b) a second part, G2A, comprising from about 30 to about 95% w/w of the total dose of acarbose, c) a third part, G2B, comprising from about 10 to about 90% w/w of the total dose of orlistat, and d) a fourth part, G3, comprising from about 10 to about 80% w/w of the total dose of orlistat, and the total concentration of acarbose and orlistat, respectively, in the composition is 100% w/w.

An oral dosage form of an antidiabetic pharmaceutical composition comprises a core portion, an outer portion, and a controlled membrane film sandwiched therebetween. The core and outer portions respectively comprise a first antidiabetic agent and a second antidiabetic agent, such as metformin HCl and sitagliptin phosphate, each at a therapeutically effective amount. The controlled membrane film encapsulates the core portion and is provided with at least one passageway for allowing the first antidiabetic agent to release out when the oral dosage form is in an aqueous environment, such as in the gastrointestinal (GI) tract of a subject. The oral dosage form is configured, upon a single-dose oral administration, to provide a maximum plasma concentration of the first antidiabetic agent in the subject from approximately 7.5 to 15 hours after administration. A method for manufacturing the oral dosage form of the antidiabetic pharmaceutical composition is also provided.

The present invention generally relates to a pharmaceutical composition of suitable HIF prolyl hydroxylase inhibitors. Preferably, the present invention discloses novel formulations of the compound of formula (Ia), or pharmaceutically acceptable salts of compounds of formula (Ia). More particularly the present invention relates to the pharmaceutical composition of compounds of formula (Ia) comprising compounds of formula (Ia) or its pharmaceutically acceptable salts.

##STR00001##

The disclosure describes an injection molding process for coating a tablet core to produce a coated pharmaceutical tablet, wherein the injection-molded coating is substantially continuous (e.g., completely covers the tablet core with no openings), and describes the resulting coated pharmaceutical tablet. The disclosure describes compositions for coatings and tablet cores and equipment suitable for performing the process.

Pharmaceutical compositions are provided, which comprise effective amounts of an opioid analgesic such as oxycodone, and an antiemetic, such as promethazine, to treat a subject for conditions, including for reducing or eliminating an adverse effect associated with the opioid analgesic.

The present invention relates to methods of treating subjects having heart failure with preserved ejection fraction (HFpEF) with a sustained-delivery formulation of cardiotonic 5-(pyridinyl)-2(1H)-pyridinone compounds.
