  • Patent number: 11938217
    Abstract: Stable, ready-to-use injectable pharmaceutical compositions are provided, comprising the combination of neostigmine, glycopyrrolate, and a pharmaceutically acceptable liquid vehicle, optionally with additional pharmaceutically acceptable excipients. Other aspects of the invention relate to methods for making such compositions and methods of using such compositions for reversing the effects of non-depolarizing neuromuscular blocking agents. Preferably, the composition comprises neostigmine methylsulfate, glycopyrronium bromide, and a pharmaceutically acceptable liquid vehicle, and is provided in a pre-filled, ready-to-use sealed container, such as a pre-filled syringe, suitable for intravenous administration.

  • Publication number: 20240090047
    Abstract: This Application sets forth techniques for managing the cellular connectivity state of a submerged wireless device. The wireless device can include sensors that analyze environmental conditions to determine when the wireless device is (or is not) submerged underwater as well as at what depth the wireless device is submerged underwater. The sensors can also determine different types of aquatic activity in which a user of the wireless device is currently engaged, such as swimming, snorkeling, free diving, and scuba diving. In turn, the wireless device can utilize this information to manage its cellular connectivity state in order to avoid wasteful consumptions of energy. In particular, the techniques enable the submerged wireless device to eliminate any existing cellular connection as well as connection reattempts so long as they are unlikely to succeed. Moreover, the techniques enable the wireless device to execute connection reattempts when they are appropriate and likely to succeed.

  • Publication number: 20240009188
    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: 20230248742
    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.
