An oral pharmaceutical modified release multiple-units composition for the administration of a therapeutically and/or prophylactically effective amount of a non-steroid anti-inflammatory drug substance to obtain both a relatively fast onset of the therapeutic effect and the maintenance of a therapeutically active plasma concentration for a relatively long period of time is disclosed.

A composition for controlled release of an opioid from a pharmaceutical composition, the method comprises controlling the release of at least one opioid into an aqueous medium by erosion of at least one surface of a pharmaceutical composition comprising I) a matrix composition comprising a) polymer or a mixture of polymers, b) an opioid and, optionally, c) one or more pharmaceutically acceptable excipients, and (i) a coating. The matrix composition has a conus-like shape so the surface area exposed to the aqueous medium increases at least during initial erosion of the matrix composition, and the dissolution of the opioid-when tested in a Dissolution Test as described herein with or without application of sinkers-results in a zero order release of at least 80% of the opioid contained in the composition. Such compositions are especially suitable for controlled release of an opioid to obtain a delayed pead concentration and a prolonged therapeutically effective plasma concentration upon oral administration. Once or twice daily administration is possible. The matrix typically comprises PEO and the active substance is typically an opioid such as morphine or a glucuronide thereof.

Methods and compositions for delivering a meloxicam compound are disclosed and described. In one aspect, a method may include perorally administering to a subject a therapeutically effective amount of a meloxicam compound that provides a meloxicam plasma concentration within 1 hour which is at least about 40% of the maximum plasma concentration attained by the formulation. In another aspect, a composition may include a therapeutically effective amount of a meloxicam compound in a pharmaceutically acceptable carrier including at least one of an alkalizer or a solubilizer, with the meloxicam compound having a solubility in the carrier that is greater than about 1.0 mg/gm.

A pharmaceutical dosage form such as a capsule capable of delivering therapeutic agents into the body in a time-controlled or position-controlled pulsatile release fashion, is composed of a multitude of multicoated particulates (beads, pellets, granules, etc.) made of one or more populations of beads. Each of these beads except an immediate release bead has at least two coated membrane barriers. One of the membrane barriers is composed of an enteric polymer while the second membrane barrier is composed of a mixture of water insoluble polymer and an enteric polymer. The composition and the thickness of the polymeric membrane barriers determine the lag time and duration of drug release from each of the bead populations. Optionally, an organic acid containing intermediate membrane may be applied for further modifying the lag time and/or the duration of drug release. The pulsatile delivery may comprise one or more pulses to provide a plasma concentration-time profile for a therapeutic agent, predicted based on both its pharmaco-kinetic and pharmaco-dynamic considerations and in vitro/in vivo correlations.

A composition for treating patients having non-insulin-dependent diabetes mellitus (NIDDM) by administering a controlled release oral solid dosage form containing preferably a biguanide drug such as metformin, on a once-a-day basis. The dosage form provides a mean time to maximum plasma concentration (T_max) of the drug which occurs at 5.5 to 7.5 hours after oral administration on a once-a-day basis to human patients. Preferably, the dose of drug is administered at dinnertime to a patient in the fed state.

The invention provides novel oral modified release dosage forms of neramexane which are useful for the continuous therapy of patients suffering from diseases and conditions such as Alzheimer's dementia and neuropathic pain. The compositions have drug release profiles that are suitable for achieving steady state plasma concentrations of neramexane which have relatively small fluctuation when administered on a twice-daily or even once-daily regimen. The dosage forms may be designed as modified release matrix tablets, which are optionally coated for taste masking. The invention further provides therapeutic methods of treating conditions such as Alzheimer's dementia and neuropathic pain which involve the administration of such dosage forms.

A pharmaceutical dosage form which comprises promethazine and/or a pharmaceutically acceptable salt thereof and at least one second drug.

Abstract of Disclosure A therapeutically effective compound is locally administered by associating the compound with a piece of orthopedic hardware that is implanted at an appropriate site within a body. The compound is adapted, such as through a sustained release device, to administer an effective dosage continuously over an extended period of time. The compound may be administered, for example, to a joint of a mammal by intraarticularly implanting a sustained release device to deliver the therapeutically effective compound within a synovial capsule of the joint, such that synovial fluid concentration of the compound is greater than plasma concentration of the compound. A wide range of orthopedic hardware, such as bone screws and staples, may be adapted to use in the systems described herein to provide treatment for a variety of medical conditions.
