Emesis is common when low doses of these drugs are given by the intramuscular or subcutaneous route, what drug is this?

The question seems incomplete as it does not specify the type of drug. However, based on the information given, it could be referring to opioids. Opioids, such as morphine, can cause emesis (vomiting) especially when administered in low doses via intramuscular or subcutaneous routes. This is due to the stimulation of the chemoreceptor trigger zone in the brain, which induces vomiting. However, please note that many drugs can cause emesis and the specific drug in question should be clarified for a more accurate answer.
