Antipsychotic drugs (APDs) are widely prescribed to control various mental disorders. As mental disorders are chronic diseases, these drugs are often used over a life-time. However, APDs can cause serious glucometabolic side-effects including type 2 diabetes and hyperglycaemic emergency, leading to medication non-compliance. At present, there is no effective approach to overcome these side-effe...

OBJECTIVE In light of the efficacy of newer antipsychotic agents and the possibility that drug withdrawal may negatively affect subsequent drug response, concern has arisen that the use of placebo in schizophrenia research may be unethical. This study examines the effect size of symptom exacerbation during drug washout with placebo and the effects of drug washout on the efficacy of subsequent d...

Antipsychotics are generally distinguished as atypical and typical agents, which are indicated in the treatment of acute and chronic psychoses and other psychiatric disorders. In April 2005, the US Food and Drug Administration issued a warning about the increased risk of all-cause mortality associated with atypical antipsychotic use in elderly patients with dementia. Pneumonia was one of the mo...

Every year numerous reports on antipsychotic drug trials are being published in neuropsychiatric journals, adding new information to our knowledge in the field. The information however is often hard for the reader to interpret, sometimes contradictory to comparable available studies and leaves more questions open than it actually answers. Although the overall quality of the studies is rather go...

To our knowledge, no prior study has examined the extent to which psychoactive medications are prescribed for non-psychiatric somatic illnesses or the mai...

pharmacological responses is the formation of a complex between the ligand (or drug or molecule) and its site of action (Taylor & Insel, 1990). Competitive binding experiments ascertain how specific the interaction is between a ligand and its binding site by examining the ability of various compounds to compete with a radiolabelled reference probe for the site. The more potently a drug binds to...

Both the new generation of antipsychotics and the more traditional antipsychotic drugs produce an important and meaningful improvement in patients with schizophrenia, but most patients are neither cured nor free of symptoms. As a consequence, it is common to switch from one drug to another in the hope of obtaining a better response. All antipsychotic drugs produce some side effects, so switchin...
