Clozapine is the gold-standard medicine for treating refractory schizophrenia but there are some notable serious adverse events (AE). We aimed to analyse reported rates of clozapine cardiac and haematological AEs in Australia. ⋯ The rates of serious AEs (including deaths) are low and likely an underestimate of true rates and need to be considered by clinicians in balancing the risks and benefits. Continued education on the monitoring and treatment of these AEs for consumers, carers and health professionals is essential and reporting these to the relevant national reporting agency is crucial.

Preclinical studies suggest that the GABAB receptor is a potential target for treatment of substance use disorders. However, recent clinical trials report adverse effects in patients treated with the GABAB receptor agonist baclofen and even question efficacy. How can the discrepancy between preclinical and clinical findings be explained? ⋯ Positive allosteric modulation of the GABAB receptor provides efficacy, and no observable side effects in relapse behavior whereas baclofen may cause, not only sedation, but also considerable impairment of food intake or metabolism. However, targeting GABAB receptors may be effective in reducing certain aspects of addictive-like behavior, such as cue-reactivity.
