Phenylbutazone
the "BUTE TEST"

Plan on riding for 7 days in a row (1 week straight).

DAY 1 and 2: Ride normally under saddle and monitor performance.

DAY 3, 4, and 5: Administer 2-3 grams of Phenylbutazone orally once daily in the morning. Ride under saddle 2-4 hours after administering the medication. Monitor performance.

DAY 6 and 7: Discontinue Phenylbutazone therapy (i.e. do not administer any medication before the ride). Ride normally under saddle and monitor performance.

RESULTS ANALYSIS:

Scenario #1:
The horse's performance is subadequate on day 1 and 2 (without Bute). A dramatic improvement in attitude and performance is observed on days 3, 4 and 5 (during bute administration). A regression in performance is noted on days 6 and 7 (after discontinuing the bute).
CONCLUSION: The problem(s) is likely inflammatory-/ pain-mediated. Issues that fall into this category include arthritis, tendonitis, ligament inflammation, muscle soreness, etc.

Scenario #2:
The horse's performance is subadequate and doesn't change dramatically throughout the course of the entire week.
CONCLUSION: The problem(s) is probably not inflammatory-/ pain-mediated. Issues that fall into this category are likely behavioral or biomechanical in nature and include trimming/ shoeing problems, intermittent upward patellar fixation, fibrotic myopathies, etc.
