Equagesic

Equagesic is a combination drug indicated for short-term pain treatment accompanied by tension and/or anxiety in patients with musculoskeletal disorders or tension headache.

Composition
It combines
 * aspirin 325mg (for pain relief) and
 * meprobamate 200mg (used here as a muscle relaxant).
 * In some formulations it is also quoted to contain ethoheptazine, an opioid analgesic.

Problems
Equagesic was discontinued in the USA, possibly because of more adequate drugs available. Specifically, meprobamate is more toxic than benzodiazepines, which are also useful as a muscle relaxant.

Martial artist Bruce Lee died of cerebral edema caused by allergic reaction to Equagesic, according to coroner examination.
