BACKGROUND: Kamebakaurin (KA) is an ent-kaurane diterpenoid known to have anti-inflammatory potential. In the current study, we investigated whether pretreatment with KA could ameliorate acetaminophen (APAP)-induced hepatotoxicity by inhibiting the anti-inflammatory response in mice. METHODS: Seven-week-old C57BL/6J mice were orally administered KA or olive oil emulsion for seven days. Twenty-four hours after the last KA or olive oil administration, the mice were intraperitoneally injected with 400mg/kg APAP or saline under feed deprived condition...

Protective effects of boswellic acid (BA) against acetaminophen (APAP)-induced hepatotoxicity in Balb/ cA mice were examined. BA, at 0.05 or 0.1%, was supplied for 4 weeks. Acute liver injury was induced by APAP treatment. Results showed that BA intake increased hepatic BA bioavailability. APAP treatment decreased glutathione (GSH) level, increased reactive oxygen species (ROS) and oxidized glutathione (GSSG) production; and lowered activity and protein expression of glutathione reductase (GR) and heme oxygenase (HO)-1 in liver...

[Purpose] The age at menarche in Korean women has been declining sharply. However, for the students who are just beginning to menstruate, taking pain medication might become a long-term habit continuing until adulthood. Therefore, this study investigated whether balance taping would be more helpful than medication in relieving the pain. [Subjects and Methods] Subjects of this study included 125 female students. The participants were assigned to the balance taping group, the control group, and the medication group...

At the start of the Afghanistan conflict, battlefield analgesia for US military casualties was achieved primarily through the use of intramuscular (IM) morphine. This is a suboptimal choice, since IM morphine is slow-acting, leading to delays in effective pain relief and the risk of overdose and death when dosing is repeated in order to hasten the onset of analgesia. Advances in battlefield analgesia, pioneered initially by Tactical Combat Casualty Care (TCCC), and the Army's 75th Ranger Regiment, have now been incorporated into the Triple-Option Analgesia approach...

Most children with pain are managed by either acetaminophen or ibuprofen. However, no study has so far investigated if children are prescribed adequate doses of acetaminophen or ibuprofen in emergency department. Aim of this retrospective study was to investigate the prevalence of under-dosage of these drugs in children presenting with pain in emergency department. Children initially prescribed with acetaminophen or ibuprofen for pain management were included. The χ (2) automatic interaction detection method was used considering the percentage variation from the minimum of the appropriate dose as dependent variable while prescribed drug, age, gender, body weight, type of hospital (pediatric or general), and availability of internal guidelines on pediatric pain management in the emergency department as independent variables...

Acetaminophen (APAP) is a common medication that induces hepatocellular damage in a time- or dose-dependent manner. Fibroblast growth factor 21 (FGF21) exerts a series of biological effects, including cellular repair. Compared to clinical diagnosis parameters, we aimed to evaluate whether FGF21 can serve as a sensitive biomarker for APAP-induced liver impairment. In the present study, we discussed comparable data from APAP-treated patients and parallelly established APAP-exposed mice for investigation. The resulting human serological data showed that APAP-treated patients have a visible reduction of FGF21 expression in undetected liver impairment of clinical diagnosis...

BACKGROUND: The buprenorphine transdermal system (BTDS) is approved in the US for the management of chronic pain. Due to its high affinity for μ-opioid receptors with a slow dissociation profile, buprenorphine may potentially displace or prevent the binding of competing μ-opioid-receptor agonists, including immediate-release (IR) opioids, in a dose-dependent manner. Health care professionals may assume that the use of IR opioids for supplemental analgesia during BTDS therapy is not acceptable...

Inadequate post-operative pain management can have significant impacts on patients' quality of life. Effective management of acute pain after surgery is important for early mobilization and discharge from hospital, patient satisfaction, and overall well-being. Utilizing multimodal analgesic strategies has become the mainstay of acute post-operative pain management. A comprehensive search was performed, assessing the published or otherwise publically available literature on different central nervous system (CNS) drugs [excluding opioids, non-steroidal anti-inflammatory drugs (NSAIDs), and acetaminophen] and their uses to treat acute post-surgical pain...

BACKGROUND: The widely used analgesic acetaminophen is metabolized to N-acylphenolamine, which induces analgesia by acting directly on transient receptor potential vanilloid 1 or cannabinoid 1 receptors in the brain. Although these receptors are also abundant in the spinal cord, no previous studies have reported analgesic effects of acetaminophen or N-acylphenolamine mediated by the spinal cord dorsal horn. We hypothesized that clinical doses of acetaminophen induce analgesia via these spinal mechanisms...

Acetaminophen, nonsteroidal antiinflammatory drugs (NSAIDs), and corticosteroids, historically used in perioperative management, are potent analgesic medications. They primarily inhibit the cyclooxygenase (COX) enzyme, decreasing the synthesis of prostaglandins, and modulating pain and temperature. Acetaminophen does not inhibit this synthesis at the inflammatory site. The primary mechanism of action of corticosteroids involves regulation of nuclear expression of genes involved in inflammatory pathways and other systemic effects...
