The risk of tissue damage due to extravasation is not widely appreciated for the gadolinium chelates. Care should be exercised during contrast injection, to avoid inadvertent extravasation and its deleterious consequences, in particular with the two higher osmolar agents (gadopentetate dimeglumine and gadoversetamide).

Cats can lose 25 to 30% of their obese body weight over 7 to 9 weeks without developing overt clinical signs of HL, provided that weight-reduction diets are highly palatable, contain a high quality protein, have a source of LCEFA, and are fortified with vitamins and microminerals. However, rapid weight loss may increase risk factors associated with development of diabetes mellitus.

The adherence of a sucralfate-tetracycline complex to gastric ulcers and to nearby non-ulcer sites was determined in the rabbit antrum. Persistent gastric ulcers were produced by a previously described method. The presence of the complex was assessed 1 and 4 h after dosing. Drug adherence was determined by quantitation of aluminum in stomach wall biopsies. Significantly more aluminum adhered to ulcer sites than to nearby non-ulcer sites. Adherence of the complex did not significantly decrease from 1 to 4 h. The complexation of tetracycline to sucralfate did not alter the selective adherence of sucralfate to gastric ulcers, providing a mechanism of ulcer site-selective drug delivery in the treatment of Helicobacter pylori gastric ulcer disease.
