摘要:
A device for administering a powdery medicine satisfying the requirements of portability, easy and quick operation, fabrication through simple steps, rigid structure, and economy using decreased number of parts of low cost. The device for administering a powdery medicine comprises a medicine-holding portion having at least partly flexible wall portion for defining therein a powdery medicine-container space which also serves as an air reservoir, and a medicine guide portion through which the space in said medicine-holding portion is communicated with the outside, wherein the space in said medicine-holding portion is communicated with the outside through said medicine guide portion only, said medicine guide portion is of a tubular structure having, at one end thereof, a medicine spray port at a position on the outside of said medicine-holding portion and having, at the other end thereof, a medicine suction port at a position in the space in said medicine-holding portion, the bottom of the space in said medicine-holding portion is positioned nearly just under the medicine suction port of said medicine guide portion, said medicine suction port is disposed close to said bottom, and the powdery medicine is sprayed to the outside through said medicine guide portion by depressing and relaxing the flexible wall portion of said medicine-holding portion.

A pharmaceutical composition for external use with the enhanced penetration of a pharmacologically active agent through the skin or mucosa of a warm-blooded animal, said composition comprising(A) a pharmaceutically effective amount of the pharmacologically active agent, and(B) an optically active or inactive pyroglutamate of the following formula ##STR1## wherein R represents a linear, branched or cyclic alkyl or alkenyl group having 10 to 14 carbon atoms,as a penentration enhancer.
摘要:
This invention is concerned with a composition for solid pharmaceutical preparations of active vitamins D.sub.3, having the remarkably improved stability of active vitamins D.sub.3, and an extremely advantageous process for the preparation thereof from the industrial viewpoint. The composition of this invention is a composition for solid pharmaceutical preparations of active vitamins D.sub.3 prepared by forming an outer layer comprising active vitamins D.sub.3 and an excipient, which is readily soluble in an organic solvent, around an inner layer comprising an excipient which is slightly soluble in an organic solvent.
摘要:
A powdery composition for nasal administration, where (1) the composition contains (i) a drug, (ii) a water-absorbing and gel-forming base material such as hydroxypropyl cellulose or hydroxypropylmethyl cellulose and (iii) a water-absorbing and water-insoluble base material such as crystalline cellulose or α-cellulose, (2) wherein the amount of the water-absorbing and gel-forming base material is about 5-40 wt % based on the total of the water-absorbing and gel-forming base material and the water-absorbing and water-insoluble base material, and (3) wherein the drug is unevenly dispersed more on/in the water-absorbing and water-insoluble base material than on/in the water-absorbing and gel-forming base material.
摘要:
A powdered medicine multi-dose administering device in which a hole (5c) is formed in the bottom surface of a medicine storage chamber (5a) capable of storing a powdered medicine of an amount of many times of administering operation, the hole (5c) being located at a position where a pump unit can be communicated with the exterior via a pipe (2g, 2d). At the administering position, the powdered medicine in a medicine container unit (5b) is injected out of the device together with the air through the pipe, while the hole is kept away from being brought into contact with opening means (2f).
摘要:
An administering device capable of quantitatively spraying a multi-dose of powdered medicine includes a device body (1), a storage chamber (3) detachably provided in the device body, the storage chamber (3) being capable of storing powdered medicine, the amount of which corresponds to a plurality of administering operations, an accommodation chamber (10) capable of accommodating powdered medicine, the amount of which corresponds to a single administering operation, and a medicine dispensing rotor (6) movably attached to the device body. The medicine dispensing rotor communicates the accommodation chamber with the storage chamber at a charging position (3a) and communicates the accommodation chamber with the outside of the device body at an administering position (5a) so that the powdered medicine in the accommodation chamber can be administered. A cap (20) is provided for moving the medicine dispensing rotor between the charging position and the administering position. A pump means (8) is provided for injecting air into the storage chamber through the accommodation chamber at the charging position so that the powdered medicine in the storage chamber can be stirred and a predetermined quantity of powdered medicine that has been stirred can be charged from the storage chamber to the accommodation chamber by the suction force of the pump means and/or gravity.

A biodegradable copolymer having the constituent units represented by the structures (I) and (II): ##STR1## wherein X represents a hydrogen atom, an acyl group having the formula RCO-- where R is a hydrocarbon group having 1 to 20 carbon atoms, an alkoxy group having to 20 carbon atoms, and Y represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms, and m and n are independently integers of 1 or more, m+n is at least 10, and m/(m+n) is at least 0.01 and a pharmaceutical composition containing the same.
摘要:
An extemporaneous kit of pharmaceutical substance-containing fat emulsion which consists of a fat emulsion and (a) a pharmaceutical substance composition containing pharmaceutical substance and at least one solvent selected from the group consisting of water, liquid polyalkylene glycols, liquid alkylethanolamines, and liquid polyhydric alcohols, or (b) a pharmaceutical substance composition containing pharmaceutical substance and saccharides and/or 30 amino acids as an excipient, and a process for preparation of a pharmaceutical substance-containing fat emulsion therefrom.
摘要:
The invention discloses a carburetor percolation prevention system which utilizes an electrically controlled fuel drain valve disposed in a fuel drain passage between the carburetor float chamber and the fuel tank. The electrical fuel drain valve is opened only when the engine condition sensor and the temperature sensor indicate that both the ignition switch is de-energized and the temperature near the float chamber exceeds a predetermined level.
