AbstractMany individuals with osteoarthritis (OA) also have other chronic, comorbid conditions, such as obesity, hypertension and diabetes, which can compound the risk for developing cardiovascular adverse events that have been associated with specific analgesics, most notably nonselective nonsteroidal anti-inflammatory drugs (NSAIDs) and selective cyclooxygenase-2 inhibitor NSAIDs. Pharmacotherapy may be further complicated by genetic factors that may influence drug metabolism in certain individuals. These risks may vary according to race and ethnicity. Black and Hispanic populations are known to have a higher prevalence of cardiovascular risk factors and disease, and a substantial proportion of black and Hispanic individuals possess genotypes of the cytochrome P450 (CYP) 2C9 enzyme involved in the metabolism of many NSAIDs and the CYP2D6 enzyme involved in metabolism of the dual opioid agonist/norepinephrine-serotonin reuptake inhibitor tramadol. As a result, the efficacy and safety of available analgesics may vary between patients in different racial and ethnic groups. This review article focuses on racial and ethnic differences in cardiovascular risk and genetic factors altering drug efficacy and safety and evaluates the pharmacologic options that can be used for the management of OA in these populations. Particular emphasis is given to the place of topical NSAIDs and capsaicin in the management of OA patients for whom systemic exposure to available pharmacotherapy poses particular risk. Evidence-based guidelines in OA management, as they relate to appropriate patient-specific pharmacotherapy, are also examined.
