Patents are granted by the U.S. Patent and Trademark Office at any time during a drug's development and may include a wide range of claims.

  • Solid dosage formulations of an orexin receptor antagonist
    Patent 10,098,892
    Issued: October 16, 2018
    Assignee(s): Merck Sharp & Dohme Corp.

    The present invention is directed to a pharmaceutical composition comprising the compound suvorexant, or a pharmaceutically acceptable salt thereof, a concentration-enhancing polymer, and optionally a pharmaceutically acceptable surfactant. The concentration-enhancing polymer is a polymer that forms an amorphous dispersion with suvorexant, that is insoluble or almost completely insoluble in water by (a) dissolving the suvorexant or (b) interacting with the suvorexant in such a way that the suvorexant does not form crystals or crystalline domains in the polymer. A concentration-enhancing polymer is water soluble or readily disperse in water, so that when the polymer is placed in water or an aqueous environment (e.g. fluids in the gastrointestinal (GI) tract or simulated GI fluids), the solubility and/or bioavailability of suvorexant is increased over the solubility or bioavailability in the absence of the polymer.

Drug PatentA drug patent is assigned by the U.S. Patent and Trademark Office and assigns exclusive legal right to the patent holder to protect the proprietary chemical formulation. The patent assigns exclusive legal right to the inventor or patent holder, and may include entities such as the drug brand name, trademark, product dosage form, ingredient formulation, or manufacturing process A patent usually expires 20 years from the date of filing, but can be variable based on many factors, including development of new formulations of the original chemical, and patent infringement litigation.

RLDA Reference Listed Drug (RLD) is an approved drug product to which new generic versions are compared to show that they are bioequivalent. A drug company seeking approval to market a generic equivalent must refer to the Reference Listed Drug in its Abbreviated New Drug Application (ANDA). By designating a single reference listed drug as the standard to which all generic versions must be shown to be bioequivalent, FDA hopes to avoid possible significant variations among generic drugs and their brand name counterpart.
