Do we need different treatments for very elderly COPD patients?
Population ageing is a new challenge for physicians because of the clinical complexity of the elderly. Although geriatric pharmacology is an emerging issue, very little is known and the choice of different treatments for the very elderly is still an important question. Chronic obstructive pulmonary disease is one of the most common chronic diseases throughout the world affecting prevalently older people. Despite the increasing burden of chronic obstructive pulmonary disease in older people, underdiagnosis and undertreatment in this age group are still common problems. Some patients are frail as they have impaired homeostatic mechanisms, deteriorated physiological systems, and limited functional reserve. Pharmacotherapeutic decisions should be combined with a careful assessment of comorbidity, polypharmacy, and age-related changes in pharmacokinetics and pharmacodynamics in order to minimize adverse drug events, drug-drug or drug-disease interactions, and nonadherence to treatment. There are few studies that specifically examine age as a factor influencing the pharmacokinetics and pharmacodynamics of inhaled therapies, the cornerstone of treatment for chronic obstructive pulmonary disease. This review provides a summary of age-related physiological changes and their impact on pharmacokinetics and pharmacodynamics, with particular regard to the drugs implicated in chronic obstructive pulmonary disease treatment, in order to optimize drug therapy.
