Controlled-release and stratified cyclodextrin inclusion complex vehicles
11633448 · 2023-04-25 · ·

The invention provides cyclodextrin inclusion complex delivery vehicles formulated for oral delivery, in which the cyclodextrin inclusion complex comprising N-acetylcysteine and acetaminophen as stacked guest molecules within the cyclodextrin cavity is provided together with an enzyme having a cyclodextrin-degrading activity capable of digesting the cyclodextrin, so that upon delivery of the vehicle to a target the enzyme is activated and releases N-acetylcysteine and acetaminophen from the cyclodextrin cavity. In alternative aspects, these cyclodextrin inclusion complex delivery vehicles are for example provided in the form of medicaments, food ingredients, medical food ingredients, nutritional supplement ingredients, dietary supplement ingredients, herbicides, insecticides, fungicides, animal repellents, pheromones, plant growth regulators, fragrances, fabrics or packaging materials.

Cyclodextrin compositions, articles, and methods

Cyclodextrin compositions including one or more radiation polymerizable monomers and a cyclodextrin inclusion complex, the cyclodextrin inclusion complex including a cyclodextrin compound and an olefinic inhibitor of an ethylene generation in produce, are coated onto packaging materials and cured. Treated containers and treated package inserts having the cured cyclodextrin compositions are useful in packaging of respiring plant materials.

Processes for the preparation of sugammadex

The present invention provides processes for the preparation of sugammadex: (I) In one aspect, there is provided a process for the preparation of sugammadex from 8-per-deoxy-8-bromo-γ-cyclodextrin and 3-mercaptopropionic acid. In another aspect, there is provided an alternative process for the preparation of sugammadex from 8-per-deoxy-8-bromo-γ-cyclodextrin and disodium 3 -mercaptopropionate. In another aspect, there is provided a process for the preparation of 8-per-deoxy-8-bromo-γ-cyclod extrin, which may be used in the production of sugammadex. In one such aspect, there is provided a process for the preparation of 8-per-deoxy-8-bromo-y-cyclodextrin from γ-cyclodextrin and a brominating agent. In another such aspect, there is provided a process for the preparation of 8-per-deoxy-8-bromo-γ-cyclodextrin comprising, inter alia, reacting γ-cyclodextrin with an electrophilic brominating agent, a deoxygenating agent, and an acid in the presence of an organic solvent. ##STR00001##

COMPOSITIONS AND METHODS FOR DIFFERENTIAL RELEASE OF 1-METHYLCYCLOPROPENE

A clathrate of 1-methylcyclopropene with α-cyclodextrin, obtained as a solid particulate product, is modified by comminuting, classifying, or both to obtain a modified particulate. When subjected to identical atmospheric disgorgement conditions of humidity and temperature, identical masses of the modified and unmodified particulates exhibit different rates of 1-methylcyclopropene disgorgement. Specifically, we have found that a smaller mean particle size is inversely related to a greater rate of 1-methylcyclopropene release.

Pharmaceutical compositions comprising meloxicam
11602563 · 2023-03-14 · ·

Disclosed herein are compositions comprising an NSAID such as meloxicam and/or rizatriptan in combination with a cyclodextrin and/or a carbonate or a bicarbonate. These compositions may be orally administered, for example, to improve the bioavailability or pharmacokinetics of the NSAID for the treatment of pain such as migraine, arthritis, and other conditions. Also disclosed herein are methods of treating pain, such as migraine, comprising administering meloxicam and rizatriptan to a human being suffering from pain, such as migraine. For migraine, these methods may be particularly useful when the meloxicam and rizatriptan are administered while the human being is suffering from an acute attack of migraine pain or migraine aura. In some embodiments, the combination of meloxicam and rizatriptan may be administered in a manner that results in a T.sub.max of meloxicam of 3 hours or less.
