Addressing Abuse and Misuse of Opioid Analgesics

Opioid analgesics provide effective treatment for noncancer pain, but many physicians have concerns about adverse effects, tolerance, and addiction. Misuse of these drugs is prominent in patients with chronic pain. Recognition and early prevention of misuse helps physicians identify the causes and proceed with patient care. Most persons with chronic pain have a significant medical comorbidity (eg, asthma) that affects treatment decisions.

Drug Therapy in the Elderly:

Numerous factors put elderly patients at risk for adverse drug events. On average, they take at least 6 medications a day, which increases the likelihood of drug-drug interactions. In addition, many drugs that are safe and effective in younger patients are inappropriate for older persons because of age-related changes and comorbid conditions that affect absorption, distribution, metabolism, and elimination. First-pass metabolism decreases with age, which may increase systemic absorption of some oral nitrates, ß-blockers, estrogens, and calcium channel blockers. The age-related rise in body fat increases the volume of distribution of lipid-soluble compounds, such as diazepam, and prolongs clearance. About two thirds of elderly persons have impaired kidney function; in these patients, the dosage of renally excreted drugs-such as digoxin-needs to be reduced. Other strategies for avoiding adverse drug events are detailed here.

Academic Detailing: Focus Is on Appropriate Care

The practice of academic detailing is gaining interest and momentum in some health care circles. The primary aim of academic detailing is to prevent the overuse and misuse of certain medications. This is done by educating prescribers on the therapies that are clinically appropriate as well as the costs of therapeutically similar choices. It is less an issue of switching to generics than it is of favoring step therapy or moving toward cost-effective therapeutically equivalent options. A well-designed program should maintain prescriber autonomy and quality of care while helping manage drug costs for both health plans and patients.

Diagnosis is often delayed by a nonspecific presentation Update on strategies for managing pulmonary arterial hypertension

abstract: Pulmonary arterial hypertension (PAH) is 1 of 5 types of pulmonary hypertension (PH). Symptoms may include dyspnea on exertion, fatigue, near-syncope, and palpitations. Physical findings include lower extremity edema, jugular venous distention, and a loud P2. Findings on chest radiography, transthoracic echocardiography, and electrocardiography can suggest the presence of PAH; however, right heart catheterization is the gold standard for confirming the diagnosis and for differentiating PAH from other forms of PH. It is essential to exclude chronic thromboembolic PH, since this can be surgically corrected. The treatment of PAH depends on the severity. In addition to the standard treatments, such as diuretics and anticoagulation, more advanced treatment options include prostaglandin therapy (epoprostenol, treprostinil, and iloprost), endothelin receptor antagonists (bosentan), and phosphodiesterase inhibitors (sildenafil).
