Tailoring chronic pain treatments for the elderly: are we prepared for the challenge?

Chronic pain is increasingly recognized as a disease and accounts for substantial suffering and disability worldwide. The aging 'baby-boomer' generation is creating a tsunami of elderly patients (>65 years old) for global healthcare systems (between 2010 and 2030). The phenotypic expression of chronic pain in the elderly can be influenced by co-morbid diseases (e.g. diabetes, cancer, depression, Alzheimer's disease, etc.), changes in physiological competency (e.g. drug metabolism/elimination) or cognitive reserve. Will a shift in the drug discovery paradigm be required to improve efficacy, side-effects or positively impact quality of life (QoL) in the elderly with chronic pain? This review highlights a number of potential pitfalls that should be considered when delivering valued pain relief medicines tailored for the elderly.
