This study aimed to compare the analgesic effects of intravenous ibuprofen and intravenous morphine titration for femoral shaft fractures in adult patients. In total, 293 participants were enrolled and randomly received intravenous ibuprofen or intravenous morphine titration. Their visual analogue scale (VAS) results were recorded every 5 minutes after the first administration. The VAS scores before and during transport were also measured. Meanwhile, the type and frequency of the adverse effects were also recorded in both groups. Patients treated with morphine showed a faster and greater reduction in the VAS than those in the ibuprofen group within 1 hour after the first administration. Interestingly, intravenous morphine titration provided consistent analgesia even during the further transport. No significant immediate adverse event was observed in all of the participants, except for sedation, which might be beneficial for keeping the patient quiet and might not be arbitrarily attributed to adverse effects. No addiction was noted in the morphine group. This study demonstrated that intravenous morphine titration is a faster and more efficient analgesia for femoral shaft fractures than ibuprofen in adult patients immediately after injury.

Introduction: Droperidol is a dopamine-2 receptor antagonist in the class of butyrophenone antipsychotics with antiemetic, sedative, analgesic, and anxiolytic properties. In the postoperative setting, droperidol provides an opioid sparing effect and decreases nausea/vomiting. Another butyrophenone antipsychotic, haloperidol, has been shown to reduce morphine milliequivalents (MME) administered when used for abdominal pain in the emergency department (ED).

Dysregulation of GABAergic inhibition is associated with pathological pain. Consequently, enhancement of GABAergic transmission represents a potential analgesic strategy. However, therapeutic potential of current GABA agonists and modulators is limited by unwanted side effects.

Background: Pruritus is a distressing symptom of systemic opioid analgesia that responds poorly to conventional antipruritus treatments. This study aimed to determine the incidence and risk factors for postoperative pruritus using intravenous patient-controlled analgesia (IV-PCA).
Methods: Opioid-naïve patients who underwent morphine-based IV-PCA for postoperative pain at a tertiary center between January 1, 2020, and June 30, 2023, were included retrospectively.

Purpose: Patient-controlled analgesia (PCA) has been considered for managing cancer pain; however, limited research has been conducted on optimizing continuous infusion rates with PCA. This study aimed to evaluate the efficacy and safety of a method that optimizes background infusion (BI) alongside PCA for titrating intravenous (IV) morphine in managing cancer-related pain.
Methods: Forty-four patients with solid tumors who could not manage pain with oral or transdermal opioid analgesics were randomly assigned in a 1:1 ratio to receive IV morphine through PCA or the conventional method.
Do P-glycoprotein-mediated drug-drug interactions at the blood-brain barrier impact morphine brain distribution?

P-glycoprotein (P-gp) is a key efflux transporter and may be involved in drug-drug interactions (DDIs) at the blood-brain barrier (BBB), which could lead to changes in central nervous system (CNS) drug exposure. Morphine is a P-gp substrate and therefore a potential victim drug for P-gp mediated DDIs. It is however unclear if P-gp inhibitors can induce clinically relevant changes in morphine CNS exposure.
