Alternatively, the physican can alter placement of the lollipop to slow the rate of the drug release for absorption into the patient's system. An analgesic-containing lollipop can be self-administrated by a patient in response to his own subjective experience of pain and to the patient's susceptibility to the particular drug utilized.
