ReviewTopical therapy for osteoarthritis: clinical and pharmacologic perspectives.
Nonsteroidal anti-inflammatory drugs (NSAIDs) have shown efficacy in patients with osteoarthritis (OA) pain but are also associated with a dose-dependent risk of gastrointestinal, cardiovascular, hematologic, hepatic, and renal adverse events (AEs). Topical NSAIDs were developed to provide analgesia similar to their oral counterparts with less systemic exposure and fewer serious AEs. Topical NSAIDs have long been available in Europe for the management of OA, and guidelines of the European League Against Rheumatism and the Osteoarthritis Research Society International specify that topical NSAIDs are preferred over oral NSAIDs for patients with knee or hand OA of mild-to-moderate severity, few affected joints, and/or a history of sensitivity to oral NSAIDs. ⋯ Topical diclofenac sodium 1% gel delivers effective diclofenac concentrations in the affected joint with limited systemic exposure. Clinical trial data suggest that diclofenac sodium 1% gel provides clinically meaningful analgesia in OA patients with a low incidence of systemic AEs. This review discusses the pharmacology, clinical efficacy, and safety profiles of diclofenac sodium 1% gel, salicylates, and capsaicin for the management of hand and knee OA.

OxyContin (controlled-release oxycodone hydrochloride) (Purdue Pharma, Stamford, CT) was approved in 1995 by the US Food and Drug Administration (FDA) for moderate-to-severe chronic pain. Crushing and snorting the delayed-release tablets results in a rapid release of the drug, increased absorption, and high peak serum concentrations. The propensity for addiction to OxyContin and the trend of increased prescription drug abuse have made it imperative for physicians and health care providers to recognize the clinical presentation of overdose and know how to manage associated complications. ⋯ With increasing rates of prescription drug abuse, OxyContin will continue to present challenges to physicians and health care providers. Physicians should be aware of potential patients who are seeking OxyContin for recreational use.

This article reviews 4 categories of hypertensive disorders of pregnancy: chronic hypertension, gestational hypertension, preeclampsia, and preeclampsia superimposed on chronic hypertension. It focuses on the diagnosis and management of preeclampsia with emphasis on the pharmacologic management of blood pressure during pregnancy. Preeclampsia is one of the most common medical disorders affecting pregnancy, with significant maternal and fetal morbidity and mortality. The most serious maternal complications of preeclampsia include intracerebral hemorrhage, eclampsia, and renal failure, as well as hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome and posterior reversible encephalopathy syndrome (PRES).
