Injectable depot compositions comprising a biocompatible polymer which is a polymer or copolymer based on lactic acid and/or lactic acid plus glycolic acid having a monomer ratio of lactic to glycolic acid in the range from 48:52 to 100:0, a water-miscible solvent having a dipole moment of about 3.7-4.5 D and a dielectric constant of between 30 and 50, and a drug, were found suitable for forming in-situ biodegradable implants which can evoke therapeutic drug plasma levels from the first day and for at least 14 days.

The present invention relates to a sustained-release pharmaceutical composition intended for animal use, which comprises a drug, a sugar, a wax, and a water-soluble polymer.

This disclosure relates to extended release oral dosage forms comprising a matrix containing a viscosity modifier (but no lipid) and coated granules containing a high water-soluble, high dose drug. The dosage forms have alcohol resistance and may also have crush resistance.

The present invention provides methods and compositions useful in the regeneration of damaged, lost and/or degenerated tissue in humans and animals. In certain embodiments, the present invention provides an acellular bioabsorbable tissue regeneration matrix, methods of making such a matrix, and methods of using such a matrix for the regeneration of damaged, lost and/or degenerated tissue. In certain embodiments, methods and compositions of the present invention are useful in the treatment of damaged, lost and/or degenerated nerve tissue.

Disclosed in certain embodiments is a controlled release oral dosage form comprising a therapeutically effective amount of a drug susceptible to abuse together with one or more pharmaceutically acceptable excipients; the dosage form further including a gelling agent in an effective amount to impart a viscosity unsuitable for administration selected from the group consisting of parenteral and nasal administration to a solubilized mixture formed when the dosage form is crushed and mixed with from about 0.5 to about 10 ml of an aqueous liquid; the dosage form providing a therapeutic effect for at least about 12 hours when orally administered to a human patient.

Sustained release formulations of nalbuphine or pharmaceutically acceptable salts thereof; methods for making the sustained release formulations of nalbuphine or pharmaceutically acceptable salts thereof; and methods for using the sustained release formulations of nalbuphine or pharmaceutically acceptable salts thereof to treat patients suffering from pain are provided.

The present invention is directed to a composition that can be used to deliver an antipsychotic drug such as risperidone, paliperidone or a combination thereof, as an injectable in-situ forming biodegradable implant for extended release providing therapeutic plasma levels from the first day. The composition is in the form of drug suspension on a biodegradable and biocompatible copolymer or copolymers solution using water miscible solvents that is administered in liquid form. Once the composition contacts the body fluids, the polymer matrix hardens retaining the drug, forming a solid or semisolid implant that releases the drug in a continuous manner. Therapeutic plasma levels of the drug can be achieved from the first day up to at least 14 days or more even up to at least four weeks.

Abuse-resistant, controlled release opioid tablets are a combination containing an opioid antagonist such as naloxone at a level above that needed to suppress the euphoric effect of the opioid, if the combination were crushed to break the controlled release properties causing the opioid and opioid antagonist to be released as a immediate release product as a single dose. The controlled release nature of the table prevents the accumulation of orally effective amounts of opioid antagonist when taken normally. The opioid antagonist is contained in a controlled-release matrix and released, over time, with the opioid.

Disclosed in certain embodiments is a controlled release oral dosage form comprising a therapeutically effective amount of a drug susceptible to abuse together with one or more pharmaceutically acceptable excipients; the dosage form further including a gelling agent in an effective amount to impart a viscosity unsuitable for administration selected from the group consisting of parenteral and nasal administration to a solubilized mixture formed when the dosage form is crushed and mixed with from about 0.5 to about 10 ml of an aqueous liquid; the dosage form providing a therapeutic effect for at least about 12 hours when orally administered to a human patient.

Disclosed are a method and an appliance for extending the production of nitric oxide by microencapsulated spinach extract powder and acidic gel. The appliance includes a microencapsulated spinach extract acting as a nitric oxide donor, and an acidic gel having a sufficient acidity to transform the spinach extract into nitric oxide. The method and appliance for extending the production of nitric oxide by spinach extract microencapsulated powder and acidic gel can release NO for a long time and provide a long-term effect to the affected position.
