Abstract
Metoclopramide (MCP) was used as an antiemetic agent in 11 pediatric oncology patients during 22 courses of cancer therapy including cisplatin, doxorubicin, and other agents. Initial MCP regimens used 2 mg/kg/dose iv prior to and at 1.5, 3.5, 5.5, and 8.5 hours post-chemotherapy. Subsequent dose reduction to 1 mg/kg and addition of diphenhydramine to all regimens has been made to decrease adverse drug effects. Seven of 11 children reported subjective benefit, defined by comparison with previous antiemetic response, comfort, and willingness to continue MCP therapy. MCP effectively reduced the volume of emesis per 24-hour period as compared with volume of emesis recorded following other antiemetics, an observation that should be confirmed in controlled studies of efficacy.
Acute dystonic reactions developed in five children, occurring most frequently in those who received 2 mg/kg/dose regimens or consecutive day dosing. These reactions were rapidly reversible with diphenhydramine, but limited patient acceptance of further MCP use.
