摘要:
The present invention pertains to a dual control sustained release drug delivery system which comprises a core and a porous coating layer over the core, wherein the coated core comprises (A) a core comprising in percentages by weight of the core composition (a) a medicament present in an amount from about 60% to about 90%; (b) an edible material having a melting point from about 25.degree. C. to about 100.degree. C. selected from the group consisting of (i) fatty acids having an iodine value from about 1 to about 10, (ii) natural waxes, (iii) synthetic waxes, and (iv) mixtures thereof, present in an amount from about 5% to about 40%; and (B) a porous coating layer over the core comprising in percentages by weight of the coating layer composition (a) a pH-independent water-insoluble polymer present in an amount from about 40% to about 80%; and (b) a water-soluble film forming polymer present in an amount from about 20% to about 60%.
摘要:
Novel pharmaceutical compositions are comprised of the salt or ion pair formation of a non-steroidal anti-inflammatory drug and an antihistamine or other decongestant. The physico-chemical characteristics of these compositions show them to be substantially different from their parent acid or base and will enable the preparation of dual action sustained or enhanced relief therapy regimens. The compositions also possessed enhanced stability and therefore the multi-symptom relief can be incorporated into a number of dosage forms such as capsules, tablets, elixirs, ointments and the like.
摘要:
Improved oral formulations are prepared by admixing gemfibrozil with from 1 to 4%, by weight, of a pharmaceutically acceptable surfactant having an HLB value of from about 10 to about 50.
摘要:
The present invention is a stabilized enteric-coated pharmaceutical dosage form and processes for the preparation thereof. Dissolution stability after storage of the dosage form under high stress conditions is improved by an enteric-coated dosage form having an enteric coating wherein the coating is of the acrylic resin kind of from 14 mg/cm.sup.2 to 24 mg/cm.sup.2 or an enteric coating wherein the coating is of the acetate kind of from 14 mg/cm.sup.2 to 24 mg/cm.sup.2 and having a second coating of hydrophilic coating for example, hydroxypropyl cellulose, hydroxymethyl cellulose or hydroxypropylmethyl cellulose.

摘要:
An orally administrable formulation of a biologically active, acid sensitive, proteinaceous agent comprises a composition of a lyophilized mixture of the proteinaceous agent and maltose, optionally with a particulate diluent. This composition is then uniformly coated with an alkaline-soluble polymeric film containing at least one partially esterified polymethacrylic acid as a major component.
摘要:
A water-dispersible formulation of gemfibrozil comprising finely divided particles of pure gemfibrozil uniformly coated with a mixture of a wax and at least one hydrophilic material, the coated particles in turn being overcoated with a minor amount of a surfactant.
摘要:
A composition for the transmembranal, including transdermal, administration of a pharmaceutical preparation comprising cross-linked carboxymethylcellulose, an alcohol soluble poly (2-hydroxyethyl) methacrylate), a permeation enhancer, such as a mixture of linoleic acid and propylene glycol, and a biologically active material, as well as a device for administering the aforementioned composition to mammals, and also a method for administering transdermally to a mammal an effective amount of the aforementioned composition.
摘要:
Thrombin solutions can be rendered storage stable using stabilizing quantities of an anti-autolytic buffer in combination with low levels of saline and glycerol to prevent denaturation.
摘要:
Certain derivatives of procaterol are believed to possess similar biological activity to the base compound, (i.e., as bronchodilators) but have greater stability and bioavailability.
