A Drug's Activity Against Anaerobes is the Leading Attribute in Antibiotic Selection, According to a New Report from AMR and Decision Resources

MALVERN, Pa. and WALTHAM, Mass., May 27 /PRNewswire/ -- Arlington Medical Resources (AMR) and Decision Resources find that surveyed physicians will increase prescribing of Wyeth's Tygacil, Merck's Invanz and Johnson & Johnson's Doribax in the next five years for the treatment of intra-abdominal infections because of their potent broad-spectrum activity and efficacy against gram-negative and anaerobic organisms.

"Treatment for intra-abdominal infections is largely empiric," stated Lisa Arias, analyst at Decision Resources. "A variety of organisms, particularly gram-negative aerobic bacteria and anaerobes, are documented in patients with an intra-abdominal infection. In fact, the leading attribute that physicians surveyed look for in a drug to treat intra-abdominal infections is its activity against anaerobes."

The new report entitled Hospital Anti-Infectives Insight Series: Intra-Abdominal Infections also finds that 96 percent of surveyed physicians cite a drug's activity against anaerobes as the leading attribute in antibiotic selection. Intra-abdominal infections are often polymicrobial in nature and involve anaerobes specific to the etiology of the infection, so activity against these organisms is advantageous even without bacterial confirmation.

"Physicians also rank availability in intravenous formulation and a low propensity to induce resistance as other important drug attributes that influence their selection in antibiotics," added Ms. Arias. "While some agents with anaerobic and gram negative activity, such as carbapenems, address some of these attributes, no antibiotic captures all of the top most important attributes which leaves opportunity for novel products to differentiate themselves."
