AgVetLink Special issue for Veterinarians May 2006
Antibiotic Sales 2004/2005
The antibiotic sales for the April 2004 to March 2005 year indicate a 12.7% drop in sales from the previous year. As this data only reflects sales and not use, overinterpreting variation from year to year should be treated with some caution (see tables below).
When putting this information together no assumptions are made about use on- or off-label and, as a result, the actives are simply categorised on the registered indications. Where products are approved for use in a range of species such as cats, dogs, horses and cattle they are simply classified as ‘unknown‘. Use classified as ‘others’ include topical, ophthalmic and intrauterine routes. We make no assumptions from the information we hold as to how any of these products are used. Feedback from the various agricultural sectors and veterinarians in particular is important in understanding any apparent trends. Individual veterinarians can comment on this data as it relates to the actual use of antibiotics either by directly contacting the ACVM Group or via industry groups and the New Zealand Veterinary Association.
The changes in sales of note are:
• A decrease of zinc bacitracin by 33%.
• Furazolidone sales decreased by over 60%.
• Oxytetracyline and sulphonamide sales continue to show increased sales.
• Tylosin and macrolides in general increased slightly following a large drop the previous year.
• Injectable amoxicillin quantities have nearly trebled.
• Ampicillin, Cloxacillin and Cephalonium sales in intramammary products show a significant increase. Approximately 70% of the total antibiotic actives used in intramammary products is for dry cow therapy.
• Aminoglycosides sales show no clear trend in recent years. The largest component is streptomycin/ dihydrostreptomycin, which increased substantially from 2003 to 2004 only to show a moderate decrease in the latest figures.
