Abstract: The present invention provides for the use of an NMDA receptor antagonist, preferably memantine or neramexane or a pharmaceutical acceptable salt or a prodrug of said antagonists, in the preparation of a pharmaceutical composition for the prevention, amelioration and/or treatment of disorders of metabolism influencing body weight, in particular obesity, an eating disorder and/or in the regulation of appetite. Furthermore, the present invention provides for a method for the prevention, amelioration and/or treatment of disorders of metabolism influencing body weight, in particular obesity, an eating disorder and/or in the regulation of appetite comprising the step of administering to a subject in need thereof a therapeutically effective amount of an NMDA receptor antagonist, preferably memantine or neramexane or a pharmaceutically acceptable salt or prodrug of said antagonists.

Abstract: The inventions relates to a small light device (1) for inhaling medicaments using supported pressure respiration, comprising a mouthpiece (2), a reservoir (5; 12), which has a variable volume for receiving respiratory gas and which can be connected to the mouthpiece (2) and into the flow either directly or using a distributor (3), an adjustable, gas-tight closer (8) between the mouthpiece (2) and the reservoir (5; 12) and at least one connecting element (10; 17) for the medicament supply to the reservoir, (5; 12), said medicament being supplied either directly or indirectly, using a distributor (3). The reservoir (5; 12) has a wall which adjusts to its change in volume. Said wall can be expanded against a restoring force by the pressurised influx of respiratory gas, in such a way that the supported pressure respiration take place using the effect of the restoring force during inhalation of the respiratory gas which contains the medicament.
