Review Comparative Study
Safety of varenicline in patients with cardiovascular disease.
Smoking cessation lowers the risk of death substantially in patients with cardiovascular disease. Although varenicline is an effective medication for smoking cessation, its safety in this population has been questioned and evaluated in several studies. In 2 randomized controlled trials of patients with cardiovascular disease, the rates of serious cardiovascular events were up to 2% higher in patients receiving varenicline than placebo, though the differences were not statistically significant. ⋯ In an observational study, varenicline was not associated with an increased risk of events when compared to bupropion in a subgroup analysis of patients with a history of cardiovascular disease. Because the evidence on the safety of varenicline in this population is limited and conflicting, additional data are needed to formulate stronger conclusions. In the meantime, health care professionals should consider individual smoking patterns, concomitant medical conditions, and cost when recommending smoking cessation pharmacotherapy for patients with cardiovascular disease.

The misuse and abuse of prescription medications in the United States continues to increase despite interventions by health care professionals, regulatory, and law enforcement agencies. Opioid analgesics are the leading class of prescription drugs that have caused unintentional overdose deaths. Benzodiazepines when taken alone are relatively safe agents in overdose. ⋯ The pharmacodynamic actions of these agents differ as their combined effects produce significant respiratory depression. Physician and pharmacy shopping by patients occurs, and prescription drug-monitoring programs can provide important information on benzodiazepine and opioid analgesic prescribing patterns and patient usage. Health care professionals need to inform patients and work closely with regulatory agencies and legislatures to stem the increasing fatalities from prescription drug unintentional overdoses.

Hypercholesterolemia affects over 34 million adults in the United States and is a major cause of coronary heart disease (CHD). Conventional therapies, such as statins, have demonstrated their ability to improve clinical end points and decrease morbidity and mortality in patients with CHD. Lomitapide (Juxtapid(®)), mipomersen (Kynamro(®)), and icosapent (Vascepa(®)) are 3 novel agents approved by the US Food and Drug Administration in the past 2 years, which offer new lipid-lowering treatment options with unique pharmacology.

To calculate the return on investment (ROI) for a targeted medication intervention program developed by corporate management of a community pharmacy. ⋯ This 6-month study resulted in an ROI to the pharmacy chain of negative 3%. Under the current reimbursement model, for this program to break even, the average time to complete one targeted medication intervention must equal 21.85 minutes or less.

Warfarin is frequently used for the prevention and treatment of thromboembolism, yet it is associated with numerous drug interactions. Regarding over-the-counter pain medications, the preferred analgesic for those patients who are taking warfarin is acetaminophen. ⋯ For those practitioners who manage warfarin therapy, there is little guidance regarding management of the drug-drug interaction between warfarin and acetaminophen. This review seeks to evaluate the drug interaction between warfarin and acetaminophen and provides recommendations for concurrent use of these drugs.
