“…Drugs such as omeprazole or famotidine could be considered to reduce the risk of gastrointestinal side effects from NSAIDs; although there is no published evidence in companion animals, there is evidence in humans that this approach can reduce the risk of NSAID-induced gastric or duodenal ulceration. [26][27][28] Routine biochemical monitoring for renal and liver function and evidence of gastrointestinal ulceration is recommended for all dogs on NSAIDs, especially those considered at risk of urinary tract obstruction. Cytotoxic agents with reported activity include mitoxantrone, carboplatin, cisplatin, doxorubicin, vinblastine, gemcitabine, vinorelbine, metronomic chlorambucil, and intravesical mitomycin C. 18,[29][30][31][32][33][34][35][36][37][38][39] Mitoxantrone, carboplatin, and vinblastine in combination with NSAIDs are common first-line agents with reported response rates ranging from 35% to 38%.…”
