SUBJECT: Changes to the elimination guideline for CLENBUTEROL
This memo is to inform the horse racing industry of upcoming changes to the elimination guideline for CLENBUTEROL.
Specifically:
1. The current elimination guideline for the 0.40 mg oral dose given twice daily for 5 days of clenbuterol (Ventipulmin) contained in the 2011 edition of the Schedule of Drugs booklet will be increased from 72 hours to 168 hours (7 days).
2. CPMA is temporarily removing the elimination guideline for the 0.30 mg intravenous single administration until further studies are completed.
3. The 0.32 mg oral single administration will no longer have an elimination guideline.
There are several medications that may be used as alternatives for clenbuterol. The CPMA provides elimination guideline for some of these substances in the 2011 Schedule of Drugs.
To allow ample time for the industry to adjust to the new elimination guidelines, these changes will come into effect on September 1, 2015 and will be reflected in the next version of the Schedule of Drugs booklet expected to be released later this year.
As always, the CPMA recommends that owners and trainers consult their own veterinarian for advice and guidance in the use of all drugs.
