The use of dimethyl sulphoxide in equine medicine is discussed with sp
ecial reference to trauma of the central nervous system, chronic endom
etritis, trauma of the locomotor apparatus, and ischaemic bowel pathop
hysiology. The ability of dimethyl sulphoxide to reduce connective tis
sue formation might be of interest in abdominal surgery. The anti-infl
ammatory effect of dimethyl sulphoxide is used in the treatment of mus
cle trauma, tendinitis, laminitis, and arthritis. Dimethyl sulphoxide
can potentiate the effects of other drugs. The most common dose is 1 g
/kg body weight intravenously up to a 40%-solution with a maximum dura
tion of treatment of 5 days. Dimethyl sulphoxide has not been approved
for use in horses in the Netherlands.
