**3.2.2.4. Other drugs**

Benzodiazepines (Sanders, 2011), antipsychotics with strong anticholinergic effects (e.g. clozapine) (Centorrino et al., 2003), antiparkinson medications (i.e. levodopa) (Delmas et al., 2008) are among the other drugs that were erorted to be associated with delirium. A systematic review of prospective studies that investigated the association between medications and risk of delirium reported that delirium risk appears to be increased with opioids, benzodiazepines, dihydropyridines and possibly antihistamine. The authors conluded that there appears to be no increased risk with neuroleptics or digoxin and there is uncertainty regarding H(2) antagonists, tricyclic antidepressants, antiparkinson medications, steroids, non-steroidal anti-inflammatory drugs and antimuscarinics (Clegg, A. & Young, 2011).
