Hollow candy for delivering liquid medicine for human consumption
20240057633 · 2024-02-22 ·

Confectionery products such as candies where a homogenous mixture of hard sugar-based coating or chewable soft coating have an inner hollow pouch to infuse medicines and a central vein to lead from a top to a central cavity or pouch. A preferred combination of sweet and fruit flavor profiles with the prescribed medicine hidden within it, provides a confection which is attractive for children, and is crispier, fresh and crunchier once consumed by the user.

APTAMER BIOCONJUGATE DRUG DELIVERY DEVICE

A delivery device for an active agent comprises nanoparticles based on a biopolymer such as starch. The delivery device may also be in the form of an aptamer-biopolymer-active agent conjugate wherein the aptamer targets the device for the treatment of specific disorders. The nanoparticles may be made by applying a high shear force in the presence of a crosslinker. The particles may be predominantly in the range of 50-150 nm and form a colloidal dispersion of crosslinked hydrogel particles in water. The biopolymer may be functionalized. The aptamer may be conjugated directly to the cross-linked biopolymers. The active agent may be a drug useful for the treatment of cancer. The delivery device survives for a period of time in the body sufficient to allow for the sustained release of a drug and for the transportation and uptake of the conjugate into targeted cells. However, the biopolymer is biocompatible and resorbable.

Fucoidan nanogels and methods of their use and manufacture

Described herein are polymeric drug-carrying nanogels that are capable of targeting to P-selectin for the treatment of cancer and other diseases and conditions associated with P-selectin. Furthermore, in certain embodiments, the nanogels presented here offer a drug release mechanism based on acidic pH in the microenvironment of a tumor, thereby providing improved treatment targeting capability and allowing use of lower drug doses, thereby reducing toxicity.
