A delivery device for a 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, such as cancer. The delivery device survives for a period of time in the body sufficient to allow for transport and uptake of the delivery device into targeted cells. The degree of crosslinking can provide a desired release profile of the active agent at, near or inside the target cells. The nanoparticles may be made by applying a high shear force in the presence of a cross linker. The particles may be predominantly in the range of 50-150 nm and form a colloidal dispersion of crosslinked hydrogel particles in water.

The present invention relates to crystal modifications of 1,1-dioxo-3,3-dibutyl-5-phenyl-7-methylthio-8-(N—{(R)-α-[N—((S)-1-carboxypropyl)carbamoyl]-4-hydroxybenzyl}carbamoylmethoxy)-2,3,4,5-tetrahydro-1,2,5-benzothiadiazepine (odevixibat), more specifically crystal modifications 1 and 2 of odevixibat. The invention also relates to a process for the preparation of crystal modification 1 of odevixibat, to a pharmaceutical composition comprising crystal modification 1, and to the use of this crystal modification in the treatment of various conditions as described herein.

The present application discloses pharmaceutical compositions and methods of treating neurological disorders and seizure disorders with the high dose modified release compositions of huperzine. The pharmaceutical compositions and methods described herein, allow for higher dosing of huperzine, while avoiding rapid peak plasma levels, thereby avoiding the dose-limiting adverse events associated with the immediate release formulations.

Microcatheters and methods for modifying and delivering suspended particles to target bodily parts (e.g., of a cardiovascular system). Embolization microcatheters and uses thereof in performing local embolization procedures, involving modifying flow characteristics (momentum) of suspensions during delivery. Applicable for delivering embolization material in a small blood vessel towards a target bodily part, and for performing local embolizations in small blood vessels feeding (possibly, cancerous) target bodily parts, thereby forming emboli therein, while preventing or minimizing non-target embolization. An exemplary catheter includes: a tubular wall with proximal and distal wall ends, and a lumen extending therebetween, opened and configured to allow passage of a suspension to a distal outlet; the distal outlet shaped or/and sized to allow passage of both a suspension fluid and particles; a proximal outlet configured to allow passage of the suspension fluid without particles and to block passage of the particles, during delivery of the suspension.

The invention relates to modified release oral formulations of therapeutic agents, including gamma hydroxybutyrate (GHB), paracetamol, codeine or oxycodone, which are resistant to alcohol induced dose dumping. Provided are formulations that have improved resistance to rapid release of the active ingredient in the presence of increasing amounts of alcohol. Also provided are formulations that can reduce or prevent the release of the active ingredient following exposure to alcohol-containing media. The invention also relates to methods of making the formulations, and methods of their use for the treatment of sleep disorders such as apnea, sleep time disturbances, narcolepsy, cataplexy, sleep paralysis, hypnagogic hallucination, sleep arousal, insomnia, and nocturnal myoclonus.

Chitosan can be coated, e.g., in 0.06 or 0.6 wt. %, over spherical silica, e.g., HYPS, loaded with spinel ferrites of theoretical formula MFe.sub.2O.sub.4, wherein M is Ni, Cu, Co, and/or Mn, e.g., at 30 wt. %, and cisplatin. Chitosan can be fabricated over Pt or cisplatin) bound CuFe.sub.2O.sub.4-HYPS and CuFe.sub.2O.sub.4-HYPS followed by Pt loading. Cisplatin and Pt-CuFe.sub.2O.sub.4-HYPS-chitosan at 0.025 to 0.5 mg/mL exhibit cytotoxicity against human breast cancer cell line (MCF-7) and human embryonic kidney cells (HEK293), relative to Pt-CuFe.sub.2O.sub.4-HYPS, with Pt-CuFe.sub.2O.sub.4-HYPS-chitosan, showing non-significant anti-cancer effects due to mediated Pt release. Pt-CuFe.sub.2O.sub.4/HYPS and CuFe.sub.2O.sub.4-HYPS-chitosan-Pt reduced cell viability using a different dose effect. Cisplatin in certain composites was less cytotoxic to HEK293 than MCF7, making the a targeted drug delivery system. Inventive composites may improve multifunctional theranostic applications involving pH stimuli, temperature-based drug release, and diagnosis based treatment such as hyperthermia.

The invention provides methods for treating a patient with constipation-predominant irritable bowel syndrome by administering a therapeutically effective dose of linaclotide.

The present invention is directed to compositions including probiotic bacteria in the form of biofilm, wherein the biofilm includes at least two bacterial species. Further provided are a method of using the composition of the invention, and a method of making same.

Compositions and methods for treating eye disorders by administering a drug delivery system into an eye compartment of the patient, wherein the drug delivery system contains a particle containing a core; a coating associated with the particle, wherein the coating is covalently or non-covalently associated with the particle and presents a hydrophilic region to the environment around the particle; and a therapeutic agent are disclosed. The eye compartment can exhibit reduced inflammation or TOP after administration of the drug delivery systems to a patient than if a drug delivery system including an uncoated particle were administered to the patient.

Therapeutic compliance and more particularly a composition having: a drug substance, selected from an active ingredient and a placebo, and a detection agent. The drug substance being different from the detection agent. The composition being configured such that the detection agent allows to indicate an ingestion of the drug substance. The composition is such that the detection agent includes a hydride that will dissolve upon contact with an aqueous medium in a human or non-human animal body, releasing dihydrogen.
