The present invention relates to a novel
nasal spray containing an
aqueous solution or a fluid with an
anxiolytic or
anticonvulsant substance, wherein the
nasal spray is characterized in that with the
nasal spray, two sprays with each an equivalent, defined volume of the
aqueous solution or liquid of the
active agent, can be intranasally administered to a patient and wherein the nasal spray allows for an administration, independent of the spatial orientation of the nasal spray in any position of the patient (standing upright, sitting,
lying or in any intermediate position). The nasal spray can be used directly without prior activation. Preferably it is apparent from the nasal spray whether a spray or even a second spray has been made with the nasal spray. Preferably, a spray of the nasal spray can be administered one-handed by the patient or a
third person. The
active agent in the inventive nasal spray is a
benzodiazepine or a GABA-
receptor agonist, preferably
midazolam or a derivative thereof or a salt of these active agents. The nasal spray according to the present invention may be used for
sedation,
premedication or treatment of patients with
claustrophobia,
anxiety disorders or
panic attacks or for the treatment of convulsions in CNS diseases, particularly in epileptic seizures or other manifestations of seizures (e.g.
febrile convulsions). The invention also relates to a method for hermetically sealing an
active agent container for use in supplying an nasal spray in accordance with the invention. The invention also relates to a method of detection by localizing the locally precise administration of an active agent in nasal application, as well as a nasal spray, preferably a bi-
dose nasal spray, for which, using the cited method of detection, it has been shown both visually (qualitatively) and quantitatively that an orientation-independent, uniform and locally precise administration of the
dose of the active agent onto the nasal mucosa of a patient can be achieved. Also provided is a method for airless and air-tight sealing of an active agent container in accordance with the invention.
