  • Patent number: 12629369
    Abstract: Amorphous solid dispersions of nilotinib fumarate or nilotinib tartrate are provided, as well as pharmaceutical compositions thereof, wherein the compositions exhibit enhanced bioavailability in the fasted state. Preferably, the compositions may be orally administered to a patient in either the fed or fasted state, with a decrease or elimination of the food effect. Preferably, following oral administration of the pharmaceutical compositions, there is no substantial difference in the pharmacokinetic parameters (e.g., Cmax, AUC0-t and/or AUC0-infinity) of nilotinib, regardless of whether the pharmaceutical compositions are administered to a subject in the fed or fasted state.

  • Publication number: 20260014169
    Abstract: Stable pharmaceutical compositions are provided, comprising a pharmaceutically effective amount of testosterone or a pharmaceutically acceptable ester thereof, a pharmaceutically acceptable oil vehicle, and a stabilizing amount of benzyl alcohol, for example, about 1% to 3% weight/volume of benzyl alcohol. The present invention also provides a process for stabilizing testosterone-containing pharmaceutical compositions by ageing them at a temperature of about 20° C. to about 60° C. for at least 48 hours, e.g., prior to secondary packing and labeling. These compositions were stable over the shelf life of the product, without exhibiting crystal formation, even upon storing at temperatures of about 2° C. to about 8° C. Other aspects of the invention relate to methods for making such pharmaceutical compositions and methods of using such pharmaceutical compositions for hormone replacement therapy, e.g.

  • Publication number: 20230234918
    Abstract: A process for producing diazomethane of Formula 1 (CH2N2), with an automated apparatus is described. A stock solution of N-methyl-N-nitroso amine in an organic solvent is continuously flown and mixed with an aqueous inorganic base at a T-mixer to form a mixture. Then it is passed through a capillary micro reactor at a temperature in a range of 20 to 30° C. to form diazomethane. The mixture is separated into an aqueous layer and an organic layer using a continuous flow micro-separator. The organic layer has 0.1-0.4 M diazomethane. The organic layer is reacted with a carboxylic acid, phenol, an alkyne, an anhydride, a carboxyl metal organic framework (MOF), or MOF coated cotton to form a corresponding ester, a pyrazole, an ether, a diazo ketone, a stable carboxyl MOF or a stable MOF coated cotton fiber.
