chemical restraint
This is a term that has emerged from the jargon of the medical world and taken centre stage in the public discussion of the treatment of the elderly in Australia.
The chemical restraint is contrasted with the physical restraint, belts or straitjackets or the like. It has been used in the treatment of psychiatric patients who might otherwise harm themselves or others, and referred to as a psychotropic drug or a psychopharmacologic agent, but it is now commonly used in the care of the elderly, particularly, those suffering from dementia. The argument is that the widespread use of chemical restraints has more to do with the convenience of the carers than the welfare of the elderly.
