Bdj | azithromycin - an alternative to penicillin?Penicillin alternative. F odontogenic infections, the poor patient tolerance of erythromycin for those who are penicillin allergic can be problematic. In this issue of the BDJ, the paper by Addy and Martin provides a very useful review of the potential value of azithromycin, a synthetic derivative of erythromycin, in dentistry. This agent has recently replaced clindamycin for the prophylaxis of infective endocarditis in children in the UK and is also recommended by the American Heart Association as an alternative to clindamycin for infective endocarditis prophylaxis in adults. The paper explains the greatly enhanced pharmacokinetics of azithromycin over erythromycin, including its increased stability at acid pH, improved absorption which is unaffected by food, sustained high tissue levels and extensive penetration of cells. Interestingly, there is preferential uptake by phagocytic cells, leading to a high drug concentration at sites of infection. These pharmacokinetics are ideal for an agent to be used in pro![]() |
Ingentaconnect is there any alternative to oral penicillin in ...Phylaxis of infective endocarditis and the paper describes a number of published animal studies supporting the efficacy of azithromycin in this role. Other significant advantages of azithromycin over erythromycin for patients are the reduced incidence of gastrointestinal side-effects, and the fact that once daily, short duration dosing regimens are appropriate, thus increasing compliance. The paper reports several studies of azithromycin in the management of odontogenic infections and periodontal diseases. Laboratory data indicate that azithromycin is bacteriostatic against a wide variety of oral organisms, including many anaerobes. However, the clinical trial data are limited and significant further work will be required before the true role of azithromycin in managing odontogenic infections becomes clear. Whilst the drug clearly has a potential role in the management of patients who are penicillin allergic, it is unlikely to supplant penicillins, such as amoxicillin, in others. It is |
