| Synthetic steroids, phenylbutazone, lead or mercuric sulphide can be added. |
| In addition, previous experimental work by Vogel indicates that acetylsalicylic acid, indomethacin, and phenylbutazone strengthen uninjured collagenous structures in rats. |
| Dogs with panosteitis usually respond to analgesics such as aspirin or phenylbutazone. |
| Many horses receive phenylbutazone on a daily basis for weeks, months, or even years, potentially contributing to increased intestinal permeability. |
| Some preparations are adulterated with phenylbutazone, ephedrine, aminopyrine or mandrake root. |
| While gastric ulcers in horses are common, their presence may be due in part to the use of phenylbutazone. |
