Some embodiments of the present invention provide stimulation systems and components for selective stimulation and/or neuromodulation of one or more dorsal root ganglia through implantation of an electrode on, in or around a dorsal root ganglia. Some other embodiments of the present invention provide methods for selective neurostimulation of one or more dorsal root ganglia as well as techniques for applying neurostimulation to the spinal cord. Still other embodiments of the present invention provide stimulation systems and components for selective stimulation and/or neuromodulation of one or more dorsal root ganglia through implantation of an electrode on, in or around a dorsal root ganglia in combination with a pharmacological agent.

Provided herein are methods for treating certain conditions, including diabetes, obesity, and other metabolic diseases, disorders or conditions by administrating a composition comprising a biguanide or related heterocyclic compound, e.g., metformin. Also provided herein are biguanide or related heterocyclic compound compositions, and methods for the preparation thereof for use in the methods of the present invention. Also provided herein are compositions comprising metformin and salts thereof and methods of use.

The present invention provides compositions for extended release of an active ingredient, comprising a lipid-saturated matrix formed from a biodegradable polymer. The present invention also provides methods of producing the matrix compositions and methods for using the matrix compositions to provide controlled release of an active ingredient in the body of a subject in need thereof.

The field of the invention is that of oral pharmaceutical medicinal products or compositions, more particularly of the type of those comprising one or more active principles. The aim of the invention is to provide an improved oral medicinal product that can be administered in one or more daily doses, with modified release of active principle (in particular an active principle), for improving the prophylactic and therapeutic efficacy of such a medicinal product. This aim is achieved by means of the multimicrocapsular oral pharmaceutical form according to the invention in which the release of the AP is controlled by means of a double mechanism of triggering the release: time triggering and pH triggering. This medicinal product comprises microcapsules with modified release of active principle, each containing a core comprising the active principle and one or more swelling agents, and at least one coating making possible the modified release of the active principle.

The invention relates to a hot-melt extruded pharmaceutical dosage form with controlled release of a pharmacologically active ingredient (A) embedded in a matrix comprising a polymer (C), the dosage form exhibiting a breaking strength of at least 300 N and having an oblong shape comprising a longitudinal direction of extension, a transversal direction of extension orthogonal to the longitudinal direction of extension, a front side, an opposite back side and a circumferential rim between said front and back side; wherein the core of the pharmaceutical dosage form has a morphological orientation caused by hot-melt extrusion that is substantially orthogonal to the longitudinal direction of extension of the dosage form; and/or the release per area of the pharmacologically active ingredient (A) through the front side and the opposite back side is faster than the release through the circumferential rim.

The disclosure is directed to drug delivery devices that provide for combinations of extended and pulsed controlled release delivery of active pharmaceutical ingredient(s) APIs. The described drug delivery devices for oral administration of therapeutic compositions can include two or more populations of unit dosage forms including one or more API's in various combinations of pulsed and delayed/extended delivery formulations. The population of unit dosage forms are provided in a variety of different vehicles such as granules, beads, pellets, or tablets and can be contained within a drug delivery device of the present disclosure.

The present invention relates to a composition comprising at least one active ingredient with low aqueous solubility, said active ingredient being present therein in a form noncovalently associated with nanoparticles formed by at least one POM polymer of formula (I), and in which said active ingredient is present in a proportion of at least 5 mol/g of POM. It is also directed towards the use of such nanoparticles, noncovalently associated with an active ingredient, with a view to increasing the aqueous solubilization of said active ingredient.

Methods and systems for delivering toxin and toxin fragments to a patient's nasal cavity provide for both release of the toxin and delivery of energy which selectively porates target cells to enhance uptake of the toxin. The use of energy-mediated delivery is particularly advantageous with light chain fragment toxins which lack cell binding capacity.

Provided herein are methods for treating certain conditions, including diabetes, obesity, and other metabolic diseases, disorders or conditions by administrating a composition comprising a biguanide or related heterocyclic compound, e.g., metformin. Also provided herein are biguanide or related heterocyclic compound compositions, and methods for the preparation thereof for use in the methods of the present invention. Also provided herein are compositions comprising metformin and salts thereof and methods of use.

Drug delivery devices include a flexible elongate body having a bladder end portion, a kidney end portion, and a drug lumen extending therebetween; and a drug reservoir which is located at the bladder end portion, contains a drug, and is defined at least in part by a semi-permeable wall. Methods include inserting the device into the ureter of a patient and permitting water in the bladder to diffuse through the semi-permeable wall to create an osmotic pressure to pump the drug through the drug lumen and out of the device at the kidney end portion and into the renal pelvis.
