Abstract: The present invention provides a composition comprising a platelet aggregation inhibitor, for example, cilostazol, or a salt or derivative thereof, useful in the treatment and prevention of ischemic symptoms. The invention provides a composition which comprises nanoparticulate particles comprising the platelet aggregation inhibitor and at least one surface stabilizer. The nanoparticulate particles have an effective average particle size of less than about 2000 nm. The invention provides also a composition that delivers a platelet aggregation inhibitor, or nanoparticles comprising the same, in a pulsatile or continuous manner.

Abstract: The present invention is directed to compositions comprising a nanoparticulate antibiotic having improved bioavailability. Preferably, the antibiotic comprises nanoparticulate cephalosporin particles with an effective average particle size of less than about 2000 nm and are useful in the treatment of bacterial infection. The invention also relates to a controlled release composition comprising a cephalosporin or a nanoparticulate cephalosporin that in operation delivers the drug in a pulsed or bimodal manner for the treatment of bacterial infection. The nanoparticulate cephalosporin particles may be formulated as a controlled release drug delivery system whereby the particles are coated one or more times with one or more natural or synthetic hydrophilic or hydrophobic polymer coating materials or dispersed throughout a natural or synthetic hydrophilic and/or hydrophobic polymer matrix.

Abstract: The present invention provides a composition comprising cephalosporin useful in the treatment and prevention of a bacterial infection. In one embodiment, the composition comprises nanoparticulate particles comprising cephalosporin and at least one surface stabilizer. The nanoparticulate particles have an effective average particle size of less than about 2000 nm. In another embodiment, the composition comprises a modified release composition that, upon administration to a patient, delivers cephalosporin in a bimodal, multimodal or continuous manner. The invention also relates to dosage forms containing such compositions, and to methods for the treatment and prevention of a bacterial infection.

Abstract: The invention relates to a controlled release composition comprising a combination of isosorbide dinitrate and hydralazine, such as hydralazine hydrochloride, that in operation delivers the drug in a pulsed or multi-modal manner for the treatment of angina, ischaemic heart disease, arterial hypertension and related disease conditions. Preferably, the isosorbide dinitrate and hydralazine hydrochloride can be released from the dosage form in an erodable, diffusion and/or osmotic-controlled release profile.

Abstract: The invention relates to a multiparticulate modified release composition that, upon administration to a patient, delivers at least one active ingredient in a bimodal or multimodal manner. The multiparticulate modified release composition comprises a first component and at least one subsequent component; the first component comprising a first population of active ingredient containing particles and the at least one subsequent component comprising a second population of active ingredient containing particles wherein the combination of the components exhibit a bimodal or multimodal release profile. The invention also relates to a solid oral dosage form containing such a multiparticulate modified release composition.
