Abstract: The present invention generally relates to eutectic compositions comprising pharmaceutical agents and other beneficial substances, and in particular, to eutectic compositions where the pharmaceutical agent and beneficial substance forms a part of the eutectic composition. In one aspect, the pharmaceutical agent and beneficial substance defines part of the eutectic composition, i.e., rather than just being present within the eutectic composition. In one set of embodiments, at least about 20 mol % of the eutectic composition may comprise a hydrogen bond donor and a hydrogen bond acceptor, for example, acetaminophen and choline chloride, respectively. However, in other embodiments, the pharmaceutical agent can be either donor or acceptor, and the other agent either donor or acceptor. Other aspects are generally directed to methods of making such compositions, methods of using such compositions, kits including such compositions, etc.

Abstract: The present invention generally relates to compositions, including liquid compositions, for the delivery of pharmaceutical agents and other beneficial substances, e.g., in various forms, including but not limited to a liquid, patch, cream, lotion, or gel. For example, some aspects of the present invention are generally directed to formulations comprising deep eutectic solvents. In some cases, such formulations may exhibit surprisingly low melting points, for example, such that the formulations are liquid at ambient temperatures. Such formulations, in some cases, may be useful for facilitating absorption of pharmaceutical agents or beneficial substances that are poorly soluble in water. Also, in certain embodiments, such formulations may be substantially free of water, which some pharmaceutical agents, such as aspirin, can be sensitive to. In addition, in some cases, the formulations can be present in various delivery vehicles, such as patches, creams, lotions, gels, and the like.
