摘要:
A multi-particulate pharmaceutical composition of rapid release particles and controlled release particles comprising tramadol or a salt thereof is provided. The composition provides a rapid and controlled release of tramadol or a salt thereof in a substantially pH independent manner after oral administration to a subject. The composition can be included in a capsule, caplet, sachet, or other solid dosage form adapted to retain and then release solid pharmaceutical compositions.
摘要:
Sustained-release compositions for delivering therapeutic concentrations of isovaleramide, isovaleric acid, and certain structurally related compounds are provided for the treatment for a variety of pathological conditions, including epilepsy and spasticity, which are ameliorated by effecting a modulation of CNS activity. The ability of the compositions to sustain relatively constant levels of the drug at a therapeutic dose in the serum for extended periods of time enables a once or twice daily administration schedule.
摘要:
Present invention provides a unique drug delivery device for delivering drug by injection into a body. The drug delivery system comprises the drug and polymer which is a liquid at room temperature and a semi-solid or gel at the body temperature.
摘要:
This invention describes the application of selected polymers as novel drug delivery systems which use the body temperature and pH to induce a liquid to gel transition of the polymer which contains a drug or therapeutic agent therein. The goal of such a delivery system is to achieve a greater degree of bioavailability or sustained concentration of a drug.
摘要:
This invention relates to an eyeglass frame mounted unit dose ophthalmic drug delivery device. A unit dose of ophthalmic medicament is provided by either a preloaded disposable microsyringe, preloaded disposable tip or manually loaded calibrated microsyringe rigidly mounted on a block which itself is slidably mounted to the eyeglass frame. The device allows for the insertion of ophthalmic medication into the inferior cul de sac of the eye.
摘要:
The instant invention is directed to a multiparticulate osmotic pump, for the controlled release of diltiazem L-malate to an environment of use, said pump comprising:(I) a carrier medium which does not maintain its integrity in the environment of use;(II) a multiple of tiny osmotic pump elements each comprising:(A) a core comprises diltiazem L-malate and an effective buffering amount of sodium bitartrate surrounded by(B) a rate controlling water insoluble wall, having a fluid permeability of 6.96.times.10.sup.-18 to 6.96.times.10.sup.-14 cm.sup.3 sec/g and a reflection coefficient of less than 0.5, prepared from:(i) a polymer permeable to water but impermeable to solute and(ii) 0.1 to 60% by weight, based on the total weight of (i) and (ii), of at least one pH insensitive pore forming additive dispersed throughout said wall,wherein the total amount of diltiazem L-malate in all of the osmotic pump elements is a therapeutically effective amount.
