1 x 125ml bottle in box of Largactil syrup (chlorpromazine hydrochloride), by May and Baker, 1970-1985

‘Largactil’ is the brand name for chlorpromazine hydrochloride. This antipsychotic drug treats disorders such as schizophrenia and acute psychotic states. It is known in the US as Thorazine. It is one of the oldest drugs of this type, first prescribed in the mid-1950s. Chlorpromazine hydrochloride can be administered in different forms. These include injection, suppository, tablet, or in suspension form such as this. It has a sedative effect without causing stupor or confusion. It also has an antidepressant effect. It can treat severe anxiety. However, it can have potentially serious side effects and must be withdrawn slowly.
