This invention is directed to reduction of flake-like aggregation in nanoparticulate compositions. Also encompassed by the invention are compositions comprising a nanoparticulate active agent, at least one surface stabilizer and a flake-like aggregation reducing agent, such as a buffer and a sugar. The nanoparticulate active agent compositions comprise particles of the active agent having an effective average particle size of less than about 2000nm.

The present application relates methods for treating a depressive symptom comprising administering an effective amount of a opioid receptor agonist or a pharmaceutically acceptable salt thereof to a subject in need thereof. Non-limiting examples of such agonist include the compounds of Formulas I, II, III, and IV, as well as the compounds of Table A.


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.


Processes for providing depot injections of recrystallized aripiprazole lauroxil in which particles of the aripiprazole lauroxil have a surface area of about 0.50 to about 3.3 m 2/g; and crystals of aripiprazole lauroxil produced by such processes. The present invention provides a process for making a compound of Formula (A) in crystal form wherein Ra is CH20C(O)R and wherein R1 is a substituted or unsubstituted aliphatic moiety.

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.


The present invention provides compounds and pharmaceutical compositions for treating neurological diseases such as multiple sclerosis.
