Interest has been expressed in the effects of high melatonin milk

(milk sourced from animals milked at night) on sleep and activity levels in the elderly, where even ultra-low doses of melatonin are suggested to be of benefit [Valtonen et al. 2005]. The use of melatonin in the visually impaired with dementia might represent a ‘novel’ hypnotic treatment in this specific population, but more formal studies would be required to inform any assertions.

Currently there is little support for antipsychotic polypharmacy [Taylor, 2010]. There is no substantial evidence that it improves treatment of psychosis and some evidence that it increases the potential risk to patients [Langan and Shajahan, 2010]. However we would like to suggest that prescribing oral aripiprazole to patients who need Inhibitors,research,lifescience,medical to be on depot antipsychotic medication may be a sensible way to reduce prolactin levels in these patients. There is some evidence Inhibitors,research,lifescience,medical that aripiprazole may play an important role in treating patients with psychosis who are sensitive to elevated prolactin and patients with prolactin-secreting pituitary tumours because aripiprazole

reduces prolactin levels by about 75% whereas the other antipsychotics increase levels Inhibitors,research,lifescience,medical up to 275% [Hoffer et al. 2009]. There is also some evidence that prescribing aripiprazole to patients with antipsychotic-induced hyperprolactinemia reduces prolactin levels [Lorenz and Weinstein, 2007; Shim et al. 2007]. Other ways of reducing prolactin levels, such as dopamine agonists, may worsen psychosis [Boyd, 1995]. The addition of testosterone in men or oestrogen replacement in women to protect Inhibitors,research,lifescience,medical bone mass and improve sexual

function is another option [Casanueva et al. 2006]. Many psychiatrists would be wary of prescribing testosterone to a man with a history of aggressive or impulsive behaviour. Use of depot medication is common practice in Australia, the USA and Europe where a quarter to a third of patients with psychotic illnesses receive long-acting depot antipsychotic Dichloromethane dehalogenase medication depending on the clinical Doxorubicin settings [Barnes et al. 2009]. Guidelines suggest that depot anti-psychotic medication should be prescribed in specific circumstances, such as when a patient has expressed a preference [Moore et al. 2007] and when partial or complete lack of compliance is a significant issue [National Institute for Health and Clinical Excellence, 2009; Lehman et al. 2004]. In a UK-based study it was shown that patients within assertive outreach teams, forensic inpatient settings and acute adult wards more frequently received depot medication [Barnes et al. 2009].
