摘要:
A liposome preparation containing an immunosuppresive tricylic compound or a pharmaceutically acceptable salt thereof. Since the tricyclic compound is entrapped stably and quantitatively into the liposomes, a broad variety of drug forms and pharmaceutical preparations insuring a long duration of efficacy can be provided.
摘要:
A lotion comprising a tricyclic compound, typically 17-allyl-1,14-dihydroxy-12-�2-(4-hydroxy-3-methoxycyclohexyl)-1-methylvinyl!-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo �22.3.1.0.sup.4,9 !octacos-18-ene-2,3,10,16-tetraone, or a pharmaceutically acceptable salt thereof, a solubilizing and/or absorption-promoting agent, a liquid medium, and optionally an emulsifier and/or a viscosity increasing agent. The lotion is stable, excellent in absorption and has less irritation against the skin and sustained release. Also, the lotion is effective for the treatment and/or prophylaxis of inflammatory and hyperproliferative skin diseases and cutaneous manifestations of immunologically-mediated illnesses.
摘要:
A sustained release medicinal preparation is produced by enclosing a macrocyclic compound represented by 17-allyl-1,14-dihydroxy-12-[2-(4-hydroxy-3-methoxycyclohexyl)-1-methylvinyl)-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo[22.3.1.0.sup.4,9 ]octacos-18-ene-2,3,10,16-tetraone or 17-ethyl-1,14-dihydroxy-12-[2-(4-hydroxy-3-methoxycyclohexyl)-1-methylvinyl]-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo[22.3.1.0.sup.4,9 ]octacos-18-ene-2,3,10,16-tetraone, into the fine particles generally called microspheres which arc made of biodegradable polymer. This preparation, when, for example, given by injection, appreciably improves the transferance of said macrocyclic compound into the blood. Further, this is also used as an agent suitable for topical administration.
摘要:
This invention relates to an aqueous liquid composition for external use which contains a tricyclo compound of the chemical formula (I) presented here-under or a pharmaceutically acceptable salt thereof. More particularly, the invention relates to an aqueous liquid composition for external use characterized in that it contains said tricyclo compound and a water-soluble solubilizer. The composition of the invention is used in medical treatment.
摘要:
The invention relates to a delayed action preparation which comprises a core comprising a drug and a swelling agent and an outer membrane comprising a biodegradable high molecular weight substance characterized in that the swelling agent is contained in a sufficient amount to cause a explosion of the outer membrane of biodegradable high molecular weight substance at a definite time after administration. This preparation provides for free control over the timing of drug release and is suited for administration not only by the oral route but also by the intramuscular, subcutaneous and other routes.
摘要:
The use of a medium-chain fatty acid triglyceride as the dispersant in the preparation of a medicinal aerosol composition comprising tricyclic compound (I) dispersed in a liquefied hydrofluoroalkane propellant is described. When a liquefied hydrofluoroalkane is added to a kneaded premix of the tricyclic compound (I) and a medium-chain fatty acid triglyceride, the active ingredient is evenly dispersed in the liquefied hydrofluoroalkane. Therefore, by distributing a dispenser first with the kneaded premix and, then, with a liquefied hydrofluoroalkane under cooling or elevated pressure, there can be provided a medicinal aerosol composition having an improved uniformity of content of the active ingredient.

To provide a pharmaceutical composition comprising a water-insoluble active substance, surfactant(s) and solid carrier(s), which is improved in dissolution and oral absorption characteristics.
摘要:
The present invention relates to liposome preparations. In particular, the present invention relates to Adriamycin-entrapped liposome preparations comprising cholesterol derivatives having a negative charge as a liposome membrane constituent. Adriamycin-entrapped liposome preparations have many uses in the medical field such as maintaining high Adriamycin blood levels over a long period of time and reducing systemic toxicity, for example.
摘要:
An external skin treatment agent composition containing an active ingredient comprising a prostacyclin, and/or its optical isomer, having the formula (I): ##STR1## (wherein, R.sup.1 is a hydrogen atom, a straight chain or branched alkyl group of C.sub.1 to C.sub.10, or one equivalent of a cation, R.sup.2 is a substitutable C.sub.1 to C.sub.10 straight chain or branched alkyl group or substitutable C.sub.1 to C.sub.10 straight chain or branched alkenyl group or alkinyl group, R.sup.3 is a straight chain alkyl group of C.sub.1 to C.sub.5, and R.sup.4 and R.sup.5 are independently a hydroxyl group or formula: ##STR2## (where, R.sup.6 is a C.sub.1 to C.sub.5 straight chain or branched alkyl group)) and a carrier.
