Abstract: This invention provides novel aconitine compounds of the formula (I) or salt thereof ##STR1## wherein, R.sub.1 is a hydrogen atom or hydroxyl group; R.sub.2 is an acetyloxy group; R.sub.3 is an alkyl having 1-4 carbon atoms; and R.sub.4 is a hydrogen atom, a hydroxyl group, or an acetyloxy group; and antipyretic/analgesic/anti-inflammatory agents containing the compound as an active ingredient which are highly safe and exhibit a powerful analgsic effect and antipyretic/anti-inflammatory activities. The compound is usable alone in painful, pyretic and inflammatory illnesses but its concomitant use with morphine reinforces the analgesic effect of morphine and allows alleviation of morphine side effects through reduction in morphine dosage.
