The ability to critically assess the validity of a clinical trial is one of many important skills that a physician strives to develop. This skill helps guide clinical decision-making, and there are a number of things that we are trained to look for to help determine the validity of any given study. Right at the top of the list of factors that go into this appraisal is that of study design, with the randomized, placebo-controlled trial serving…

Ethical Considerations on the Use of Fear in Public Health Campaigns

By Ishmeal Bradley, MD

Faculty Peer Reviewed 

The goal of public health is to prevent or minimize disease and injury on a population level. How to achieve this end has changed over time, though. In previous decades, communicable diseases posed the greatest health risks. Consequently, public health officials used the tools of isolation, quarantine, and (forced) vaccination to combat these threats. Today, however, the major causes of morbidity and mortality are chronic conditions, many of which are thought to be due to lifestyle behaviors. Consider obesity,…

Avastin and the Meaning of Evidence

By Antonella Surbone MD PhD and Jerome Lowenstein MD

The recent hearings at the Food and Drug Administration regarding the revocation of approval for the use of Avastin in the treatment of breast cancer bring into sharp focus several very important issues in medicine today.

The pharmaceutical industry, armed with powerful new tools for deciphering the signaling mechanisms and mutations responsible for the development and progression of malignancies, has developed new therapies for treating cancer and other malignancies. The cost of development of each new…

Resveratrol: The Modern Fountain of Youth?

By Lee Rasamny

 For thousands of years, humans have been fascinated with the idea of slowing and perhaps even reversing the process of aging. From Ponce de León to modern research into substances like telomerase and resveratrol, philosophers, explorers, and scientists have dedicated countless hours to this pursuit.

Resveratrol, a substance found in the skin of red grapes and other plants such as eucalyptus, spruce, and lily, has developed a buzz for its hypothesized potential to slow the…

The Polymyxins: Why am I using them all the time, and what are they?

By Jon-Emile S Kenny

Faculty Peer Reviewed

A 65-year-old female with locally advanced rectal cancer is admitted to the ICU, hypotensive and febrile.  Her PICC line is removed and blood cultures drawn.  Fourty-eight hours later all cultures return ESBL Klebsiella with susceptibility only to polymyxin.

 I sat on the venerable call-room couch staring mindlessly at the cluttered, nauseating walls repeating the word ‘polymyxin’ like an endless antimicrobial mantra.  What strange dosing it has, and an even more…

Clopidogrel (Plavix®) and Proton Pump Inhibitors: An Update on the Potential Drug Interaction

By Antony Q. Pham, Pharm.D. and Reena M. Tejura, Pharm.D.

Faculty Peer Reviewed

Recent publications have described a potential drug interaction between clopidogrel (Plavix®) and proton pump inhibitors (PPIs). Several retrospective studies have concluded that the use of PPIs can lower the effectiveness of clopidogrel and as a result, increase the possibility of cardiovascular events. Limited data from prospective trials have yet to show a clinical significance from this potential interaction. The Food and Drug Administration (FDA) released an…

Zolpidem and Uncontrollable Nocturnal Eating Binges

John Cruz

Breaking News: FDA issues new warning for Exenatide (Byetta®)

Kanika Ballani, Pharm.D.
Diana Hubulasvili, Pharm.D.

 Developed by Amylin Pharmaceuticals, Exenatide (Byetta®) is an incretin mimetic that is used as an adjunctive therapy with metformin, a sulfonylurea or a thiazolidinedione to improve glycemic control in type 2 diabetic patients. Mechanistically, Exenatide mimics the actions of endogenous incretin hormone, glucagon-like peptide (GLP-1), causing an increase in insulin secretion which slows gastric emptying and leads to a decrease in food intake. On November 3rd 2009, the FDA issued a safety warning on Exenatide associating…

New National Network E-mails Drug Alerts Instantly to U.S. Doctors

Commentary by Marilena S. Antonopoulos Pharm.D, Pharmacology Section Editor

Until recently, drugs safety alerts (aka “Dear Doctor letters”) were sent out to physicians through traditional U.S. mail, a slow and error-prone process. These alerts can be significantly delayed and may not even reach the intended recipient. In an effort to improve the speed and efficacy of the delivery of FDA mandated patient safety alerts to physicians and other healthcare providers, the Health Care Notification Network (HCNN) has announced the launching of its online…
