  • Patent number: 10849894
    Abstract: Described is a composition comprising (a) a population of particles of an aripiprazole prodrug having a volume based particle size (Dv50) of less than 1000 nm and (b) at least one surface stabilizer comprising an adsorbed component which is adsorbed on the surface of the aripiprazole prodrug particles and a free component available for solubilisation of the aripiprazole prodrug. The surface stabilizer to prodrug ratio provides the optimal quantity of free surface stabilizer for the purposes of producing a lead-in formulation. Also described are methods of treatment using the aforementioned composition.

  • Patent number: 10723728
    Abstract: The invention provides a method of sustained delivery of a lactam, imide, amide, sulfonamide, carbamate or urea containing parent drug by administering to a patient an effective amount of a prodrug compound of the invention wherein upon administration to the patient, release of the parent drug from the prodrug is sustained release. Prodrug compounds suitable for use in the methods of the invention are labile conjugates of parent drugs that are derivatized through carbonyl linked prodrug moieties. The prodrug compounds of the invention can be used to treat any condition for which the lactam, imide, amide, sulfonamide, carbamate or urea containing parent drug is useful as a treatment.

  • Patent number: 10584099
    Abstract: The present invention accomplishes this by having multiple molecules of parent drugs attached to carrier moieties and by extending the period during which the parent drug is released and absorbed after administration to the patient and providing a longer duration of action per dose than the parent drug itself. Prodrug conjugates are suitable for sustained delivery of heteroaryl, lactam-amide-, imide-, sulfonamide-, carbamate-, urea-, benzamide-, acylaniline-, cyclic amide- and tertiary amine-containing parent drugs that are substituted at the amide nitrogen or oxygen atom with labile aldehyde-linked prodrug moieties. The carrier groups of the prodrugs can be hydrophobic to reduce the polarity and solubility of the parent drug under physiological conditions.
