ABSTRACT:
A pharmaceutical preparation useful for alleviating or treating a pain, e.g., a chronic pain (particularly, a neuropathic pain) is provided. The pharmaceutical preparation contains (a) a propionic acid-derived nonsteroidal anti-inflammatory agent (e.g., ibuprofen), (b) a non-pyrazolone antipyretic analgesic agent (e.g., acetaminophen), and (c) an opioid analgesic agent (e.g., codeine phosphate, dihydrocodeine phosphate). The pharmaceutical preparation may contain 5 to 100 parts by weight of the antipyretic analgesic agent (b) or 0.5 to 500 parts by weight of the analgesic agent (c) relative to 100 parts by weight of the anti-inflammatory agent (a). The pharmaceutical preparation may be substantially free from a nontoxic N-methyl-D-aspartate receptor antagonist and may contain 20 to 80 parts by weight of the antipyretic analgesic agent (b) and 1 to 100 parts by weight of the analgesic agent (c) relative to 100 parts by weight of the anti-inflammatory agent (a).
