RT Journal Article SR Electronic T1 Two more muscle relaxants JF Drug and Therapeutics Bulletin JO Drug Ther Bull FD BMJ Publishing Group Ltd SP 9 OP 10 DO 10.1136/dtb.2.3.9 VO 2 IS 3 YR 1964 UL http://dtb.bmj.com/content/2/3/9.abstract AB In 1962 we discussed muscle relaxants as a group and individually, and concluded that many of these drugs are effective sedatives without a specific muscle-relaxing action when given by mouth 1.
