Abstract

Disclosed is a pharmaceutical composition containing loxoprofen or a salt thereof and codeine or the like, which has excellent storage stability. Specifically disclosed is a pharmaceutical composition which contains at least one component selected from the group consisting of codeine, carbinoxamine or a salt thereof, clemastine or a salt thereof, chlorpheniramine or a salt thereof, diphenylpyrraline or a salt thereof, bromhexine or a salt thereof, ambroxol or a salt thereof, lysozyme or a salt thereof and dextromethorphan or a salt thereof and loxoprofen or a salt thereof in such a manner that the at least one component and loxoprofen or a salt thereof are substantially not in contact with each other.

Description

technical field [0001] The present invention relates to a pharmaceutical composition containing loxoprofen or a salt thereof. Background technique [0002] Loxoprofen is a non-steroidal anti-inflammatory analgesic (NSAID), which is known to treat rheumatoid arthritis, osteoarthritis, low back pain, periarthritis of the shoulder, neck, shoulder and wrist syndrome, toothache, acute upper It is effective in anti-inflammatory, analgesic and antipyretic after respiratory tract inflammation, post-operation, trauma and tooth extraction (Non-Patent Document 1). [0003] Starting from its excellent pharmacological effects, the combination of loxoprofen and various drugs is being studied. As the action produced by the combination, for example, the enhancement action of the anti-inflammatory, analgesic, and antipyretic effects produced by the combination with caffeine, ethyl salicylamine, and acetaminophen (Patent Document 1); Improvement of nasal congestion symptoms by combination o...
