a) a support layer, b) an adhesive layer containing an adhesive polymer, at least one hydrocolloid, hyaluronic acid or a pharmaceutical salt thereof, chondroitin sulphate or a pharmaceutical salt thereof, c) a protective layer removable at the moment of use.
摘要:
An external patch containing diclofenac hydroxyethylpyrrolidine prepared by laminating an adhesive layer on a backing, wherein said adhesive layer is characterized by comprising 5-50% by weight of styrene·isoprene·styrene block copolymer, 20-50% by weight of a tackifier resin, 5-70% by weight of a softening agent, and 0.5-20% by weight of one or more solubilizers selected from N-methyl-2-pyrrolidone, propylene glycol and dimethyl sulfoxide as essential ingredients, and 0.5-20% by weight of diclofenac hydroxyethylpyrrolidine as an active ingredient. The patch has excellent transdermal absorption, less skin-irritation and excellent stability of the drug.
摘要:
A new process, particularly simple and economical, for FSH and LH separation and purification starting from crude HMG preferably urinary, comprising the following steps: optional exhaustion of crude HMG viral charge in aqueous EtOH; ion-exchange chromatography on weakly basic anionic resins of DEAE type; affinity chromatography on resin having an antraquinone derivative as a ligand; optional ion-exchange chromatography on strongly basic anionic resins. Hormones obtained thereby, in particularly pure form and having high specific activity, may subsequently undergo a depyrogenation step.
摘要:
The present invention provides safe pharmaceutical formulations for drugs used in the treatment of drug addiction, namely formulations which render the abusive administration of the drug contained in these formulations not feasible, together with processes for obtaining said formulations.
