Cardiovascular disease remains the leading cause of mortality in elderly patients. While coronary heart disease (CHD) morbidity and mortality have decreased over the last 25 years, the percentage reduction in elderly patients is nearly 50% lower than that for the general adult population. Therefore, aggressive primary and secondary prevention of CHD is imperative for our society, and hyperlipidaemia remains the major modifiable risk factor in the elderly population. ⋯ Of the commercially available statins, rosuvastatin, atorvastatin and simvastatin have the highest potency. While rosuvastatin currently lacks clinical event data, atorvastatin has the most clinical event data for CHD and even stroke prevention. Although pravastatin has lower potency than other described statins, it also has the lowest risk of drug-drug interactions involving CYP.

Community-acquired pneumonia (CAP) is a major cause of morbidity and mortality in elderly patients. Therefore, efforts to optimize the healthcare process for patients with CAP are warranted. An organized approach to management is likely to improve clinical results. ⋯ There is good evidence that implementation of guidelines leads to improvement in clinical outcomes in elderly patients with CAP, including a reduction in mortality. Protocols should address a comprehensive set of elements in the process of care and should periodically be evaluated to measure their effects on clinically relevant outcomes. Assessment of functional clinical outcome variables, in addition to survival, is strongly recommended for this population.

Numerous recent studies have challenged the widely held belief that atypical antipsychotics are safe and effective options for the treatment of behavioural problems such as agitation in patients with dementia. Accordingly, there is a need to reconsider the place of atypical antipsychotics in the treatment of patients with dementia. The present article is intended to assist clinicians with the assessment and pharmacological management of agitation in patients with dementia. ⋯ The best evidence currently exists for cholinesterase inhibitors and serotonin-specific reuptake inhibitor antidepressants. Emerging reports suggest that numerous other medications, for example, antiepileptics, lithium, anxiolytics, analgesics, beta-adrenoceptor antagonists, cannabinoid receptor agonists and hormonal agents, may prove to be viable alternatives to antipsychotics for the treatment of severe DRA and more research is urgently needed to help assess the effectiveness of these agents. A comprehensive biopsychosocial assessment and treatment plan is likely the most effective way to manage DRA.

Zoledronic acid (Aclasta; Reclast), a third-generation nitrogen-containing bisphosphonate, is the first once-yearly treatment to have been approved for use in patients with postmenopausal osteoporosis or at high risk of fracture. Intravenous zoledronic acid 5 mg once yearly is effective in reducing the risk of several types of fracture in patients with postmenopausal osteoporosis or recent low-trauma hip fracture. ⋯ Additional comparative data are required to definitively position zoledronic acid with respect to other agents. In the meantime, intravenous zoledronic acid 5 mg once yearly is a convenient and effective treatment option that may have an advantage over some other agents, for which adherence to treatment regimens is a recognized problem.

Increased life expectancy is associated with an increased prevalence of chronic diseases and drug consumption. Changes often occur in the medication regimen after hospitalization. The extent and nature of these changes and the adherence of elderly patients have not yet been fully investigated. ⋯ The majority of elderly patients experienced modifications in their medication regimen during the first month following hospital discharge. Thirty percent of patients were non-adherent to at least one drug. To improve adherence to a hospital medication regimen, patients should be encouraged to visit their GP and the number of long-term drugs should be reduced.
