Efficacy of Caffeine as an Adjuvant to Opioid Therapy in Cancer Pain: a Randomized, Double-blind, Placebo-controlled Trial
Previous studies on cancer pain lacked assessment of quality of life. And most of previous
studies on cancer pain did not give attention to symptoms accompanied with pain. We include
such variables as outcome measures, and aimed to evaluate the efficacy and the safety of
intravenous caffeine in advanced cancer inpatients.
