Herein disclosed is a lyophilized pharmaceutical preparation obtained by lyophilizing an aqueous composition having property of reversible thermosetting gelation and comprising an effective amount of a drug, 0.2 to 2.1 (W/V)% of methylcellulose (the content of methoxyl group is within the range of 26 to 33%), 1.2 to 2.3 (w/v)% of citric acid and 0.5 to 13 (W/V)% of polyethylene glycol. The lyophilized pharmaceutical preparation makes it possible to stably store drugs unstable to water till they are put into practical use and, upon therapeutic use, an aqueous composition having property of reversible thermosetting gelation which can undergo gelation when locally applied can easily and immediately be reconstituted from the preparation by addition of a proper amount of a solvent for reconstitution.
摘要:
An O/W emulsion composition for eye drops comprises a drug selected from the group consisting of fluorometholone, clobetasone butyrate and clobetasol propionate; a phospholipid; liquid paraffine; and water. The O/W emulsion composition is excellent in solubility of fluorometholone, clobetasone butyrate and clobetasol propionate in the tear fluid. Therefore, the composition would exhibit an anti-inflammatory activity identical to or superior to those achieved by the conventional pharmaceutical preparations, by the administration thereof at a dose lower than those for these known drugs. The composition would also be excellent from the economical standpoint and permit reduction of systemic side effects which would be encountered when the conventional drugs are instilled in the eyes.
摘要:
A lipid emulsion which comprises (A) an oil component, (B) an emulsifying agent containing yolk lecithin and/or soybean lecithin, and (C) water, wherein the lipid emulsion further comprises citric acid or a pharmaceutically acceptable salt thereof and at least one member selected from the group consisting of methionine, phenylalanine, serine, histidine and pharmaceutically acceptable salts thereof, provided that it does not simultaneously contain methionine and phenylalanine. The addition of citric acid and histidine, methionine, phenylalanine and/or serine to a lipid emulsion containing natural lecithin as an emulsifying agent permits the prevention of change of color and formation of oil drops associated with the conventional natural lecithin-containing lipid emulsion due to the synergistic effect of the foregoing additives. The drug-containing lipid emulsion is also excellent in storage stability and thus the foregoing lipid emulsion can be applied to drugs such as injections, eye drops, nasal drops, lotions or liniments, inhalants and drugs for oral administration or cosmetics such as humectants.

摘要:
An illumination apparatus includes a plate-like separation optical element having a dichroic surface and a PBS surface. The dichroic surface reflects green component light and transmits yellow component light. The PBS surface transmits P polarization component light and reflects S polarization component light. The separation optical element combines red component light entering from a certain direction and transmitted through the dichroic surface, with yellow component light entering from a different direction and reflected by the PBS surface, and leads a combined light towards a red liquid crystal panel. The separation optical element combines green component light entering from the certain direction and reflected by the dichroic surface, with yellow component light entering from the different direction and transmitted through the PBS surface, and leads a combined light towards a green liquid crystal panel.
