Described are immediate release oral dosage forms that contain abuse-deterrent features. In particular, the disclosed dosage forms provide deterrence of abuse by ingestion of multiple individual doses. In addition, the disclosed dosage forms provide protection from overdose in the event of accidental or intentional ingestion of multiple individual doses.

In an example of a method for making a pulsatile delivery device, one type of charges are generated on a polymeric layer, and charges opposite the one type of charges are generated on a delivery layer including a film forming material and a predetermined substance dispersed throughout the film forming material. The charged polymeric and delivery layers are placed into contact to form a bi-layer structure. A stack with at least two bi-layer structures is formed so that the polymeric layers and the delivery layers are alternating throughout the stack. The stack is sealed so that one of the polymeric layers remains exposed.

Pharmaceutical compositions suitable for long-term storage at room temperature are described. The pharmaceutical composition comprises the compound of formula (1) ##STR00001##
and can be used for the treatment of steatohepatitis. Also described are methods for preparing the pharmaceutical composition and methods of treatment using the pharmaceutical compositions.

The present invention provides a biodegradable drug delivery composition comprising: (i) a mixture of at least three different block copolymers, wherein each block copolymer is: (a) a biodegradable triblock copolymer having the formula: A.sub.v-B.sub.w-A.sub.x wherein A is a polyester and B is polyethylene glycol and v and x are the number of repeat units from 1 to 3,000 and w is the number of repeat units from 3 to 300 and v=x or v≠x; or (b) a biodegradable diblock copolymer having the formula: C.sub.y-A.sub.z wherein A is a polyester and C is an end-capped polyethylene glycol and y and z are the number of repeat units with y=2 to 250 and z=1 to 3,000; and wherein the mixture comprises at least one (a) and at least one (b); and the weight ratio between (a) and (b) is 1:19 to 5:1; and (ii) at least one pharmaceutically active ingredient.

The invention is directed to pharmaceutical compositions such as tablets that exhibit delayed release properties when administered as either whole or half tablets. The invention is also directed to delayed release tablets comprising deferiprone for oral administration, for which twice daily administration is bioequivalent to the same daily dose of an immediate release tablet administered thrice daily. The invention is also directed to methods of making and using the same.

A GLP-1 receptor agonist has effects of reducing serious side effects due to long-term use of levodopa when administered in combination with levodopa, and also effects of alleviating or improving abnormal involuntary movements (AIMs) caused by levodopa. A method for prevention or treatment of levodopa-induced dyskinesia according to an embodiment of the present disclosure includes administering a glucagon-like peptide-1 (GLP-1) receptor agonist to a patient.

This invention relates to a bioerodible drug delivery device that can be implanted in a patient at or near an area in need of treatment. The bioerodible drug delivery device can be used to deliver a wide variety of different pharmaceutically active agents, and can do so at a controlled rate and over an extended period of time. The bioerodible drug delivery device includes a bioerodible polymeric outer housing with one or more delivery ports for delivering the pharmaceutically active agent(s) contained therein. The polymer used as the bioerodible polymeric outer housing is not substantially degraded during the dosing of the pharmaceutically active agent(s) in the bioerodible drug delivery device. The invention also provides methods of making the bioerodible drug delivery device and using it for the treatment of diseases and disorders.

The present invention relates to a melt extrusion process for preparing a solid dispersion comprising a pharmaceutically active ingredient, a polymeric binder, and, optionally, one or more auxiliary agents, comprising a) in a batch-wise operation, placing a pre-determined amount of the polymeric binder, a pre-determined amount of the active ingredient, and, optionally, a pre-determined amount of the auxiliary agent(s) in a melting vessel; melting the polymeric binder with agitation to disperse the active ingredient in the polymeric binder to obtain a molten pre-dispersion; b) feeding the pre-dispersion into an extruder to homogenize the pre-dispersion and release a melt through a die; and c) allowing the melt to solidify.
