Disease vs. drug-centred model of psychiatric medication

“The disease-centred model suggests that psychiatric drugs work because they reverse, or partially reverse, the disease or abnormality that gives rise to the symptoms of a particular psychiatric disorder. Thus ‘antipsychotics’ are thought to help to counteract the biological abnormalities that produce the symptoms of psychosis or schizophrenia… the ‘drug-centred’ model suggests that far from correcting an abnormal state, as the disease model suggests, psychiatric drugs induce an abnormal or altered state. Psychiatric drugs are psychoactive substances, like alcohol and heroin… The drug-centred model suggests that the psychoactive effects produced by some drugs can be useful therapeutically in some situations. They don’t do this in the way the disease-centred model suggests by normalising brain function. They do it by creating an abnormal or altered brain state that suppresses or replaces the manifestations of mental and behavioural problems.”
