RT Journal Article SR Electronic T1 Oxypertine (integrin) - now promoted’ for the treatment of anxiety JF Drug and Therapeutics Bulletin JO Drug Ther Bull FD BMJ Publishing Group Ltd SP 94 OP 95 DO 10.1136/dtb.9.24.94 VO 9 IS 24 YR 1971 UL http://dtb.bmj.com/content/9/24/94.abstract AB We reviewed oxypertine (Integrin) in 1967, soon after it was introduced as a major tranquilliser.1 Structurally it is related to 5-hydroxytryptamine. Capsules containing a lower dose than the original tablets are now being marketed with claims that it is a ‘fundamental’ treatment for anxiety and that ‘it goes straight to the root of the problem and combats the disturbed brain-chemistry that underlies anxiety’. Like some other major tranquillisers, e.g. reserpine, oxypertine does lower amine levels in the central nervous system in animal preparations.
