Objective: Pain is very common in the elderly, so there is a high prevalence of analgesic use among this population. The purpose of this study was to assess patterns of analgesic use and evaluate factors associated with analgesic use in elderly patients. Method: The subjects of this study were patients over 65 years old hospitalized in a teaching hospital located in Chuncheon-si, Korea between January 1, 2014 and March 31, 2014. Data collection regarding analgesic prescriptions and baseline characteristics was conducted using computerized hospital database by medical information team. Logistic regression analysis was used to identify factors related to analgesic use. Results: A total of 2,394 patients were finally included. Among these patients, 700 (29.2%) took analgesics; 521 (74.4%) out of these 700 patients were received opioid analgesics and 179 (25.6%) were received only non-opioid analgesics. The most frequently prescribed opioid analgesic was pethidine (45.7%), and the most frequently prescribed non-opioid analgesic was acetaminophen (44.1%). Fracture was associated with increased odds of opioid analgesic prescriptions (OR = 2.766, 95% CI = 2.019-3.790, p < 0.001) and any analgesic prescriptions (OR = 2.394, 95% CI = 1.766-3.244, p < 0.001). Stroke or cerebral infarction was associated with decreased odds of opioid analgesic prescriptions (OR = 0.636, 95% CI = 0.471-0.858, p = 0.003). Conclusion: A significant proportion of hospitalized elderly patients use analgesics. Health care professionals should consider factors associated with analgesic use in this population to improve pain management.

Ten 1,2,4-thiadiazolidines were synthesized and screened for their anti-inflammatory and analgesic activities. Butyl isothiocyanate was used as a starting material. Several compounds showed significant anti-inflammatory and analgesic activities. The unsubstituted and o-methyl, p-acetoxy and o-chloro substituted compounds were found to be more potent anti-inflammatory and analgesic agents than the other compounds.

Five novel cinmetacin amide derivatives as potential nonsteroidal antiinflammatory and analgesic compounds were prepared and their antiinflammatory-analgesic activity was compared with cinmetacin. Cinmetacin and hydroxysuccinimide were reacted with dicyclohexyl carbodiimide to give cinmetacin active ester (4), which was treated with amines to yield cinmetacin amides (5-9). Compounds (5) and (9) gave stronger analgesic activity than cinmetacin and compounds (5), (6), (9) showed comparable antiinflammatory activity to cinmetacin.

Nine cinmetacin derivatives as potential nonsteroidal analgesic and antiinflammatory compounds were prepared and their analgesic-antiinflammatory activity was compared with cinmetacin. Salicylic acid and phenols were reacted with dicyclohexyl carbodiimide (DCC) to give phenol salicylates (1-4). Cinmetacin was treated with DCC and phenol derivatives to yield cinmetacin esters (5-13). Compounds (5, 7, 8, 10, 12, and 13) showed stronger analgesic activity than cinmetacin, but only compound (5) showed comparable antiinflammatory activity to cinmetacin.

Objectives: Trachyspermum khasianum H. Wolff is a rare medicinal plant characteristically used by the traditional healers in traditional medicine for the treatment of throat-pain, toothache, and stomach ache. The study was designed to determine the anthelmintic and analgesic properties of the aerial parts of Trachyspermum khasianum H. Wolff (Family: Apiaceae). The aqueous and ethanol extract of T. khasianum H. Wolff was prepared and subjected for evaluation to determine the possible therapeutic effects. Methods: Anthelmintic activities of the extracts were determined by observing the time taken to paralyze and the time taken for the death of earthworms (Eisenia foetida) as compared to the standard drug-Albendazole (20 mg/ml) and control. Analgesic potential of the extracts was evaluated using Eddy's hot plate method to understand the analgesic activity in rats (Wistar rats) at 100 mg/kg and 200 mg/kg body weight doses and compared with the standard reference (Diclofenac sodium: 10 mg/kg of animals). Results: The extracts showed a significant dose-dependent anthelmintic effect at the different concentrations (10, 20, and 40) mg/ml, compared to that of the standard drug (20 mg/ml). Also, the results suggested that the plant extracts possess significantly analgesic activity in rats. Conclusion: The studies indicate that Trachyspermum khasianum shows anthelmintic and potent analgesic activities. Further research should be carried out to identify the specific phytoconstituents responsible for both analgesic and anthelmintic activities and its possible mechanism of action.

Background: The aim of this study was to investigate the safety and analgesic effects of Datura Flos pharmacopuncture (DFP). Methods: The analgesic effects of DFP were assessed using mechanical (hot plate), chemical (formalin test), and thermal (von Frey filament test) pain tests. Forty male Sprague Dawley rats were assigned randomly into DFP (75 mg/kg, 150 mg/kg), lidocaine 0.5%, or normal saline group for treatment on Kl3. Gross pathology, histopathology, biochemistry and hematology were performed. Results: In the hot plate test, DFP at a high dose (HDDFP; 150 mg/kg) produced a significant analgesic effect, at 10 and 20-minutes post injection (p < 0.01). Low dose DFP (LDDFP; 75 mg/kg) also showed an analgesic effect at 10 minutes post injection (p < 0.01). In the formalin test, HDDFP produced an analgesic effect, for 0-10 and 10-20 minutes (p < 0.01) post treatment, whereas LDDFP showed analgesic effects between 10-20 minutes (p < 0.05). In the von Frey filament test, DF-H produced an analgesic effect, 10 (p < 0.01) and 20 minutes post treatment (p < 0.05). LDDFP showed analgesic effect at 10 minutes (p < 0.05). In the acupuncture response test, HDDFP produced an analgesic effect at 10 minutes post treatment (p < 0.05). DF-H did not cause any anatomical changes to the liver or kidney and there were no abnormalities in biochemistry or hematology. Conclusion: DF-H was not toxic and provided short term analgesia, suggesting it may be useful in the management of pain.

Comparative studies were made on the analgesic effect of salicylamide, used individually and combined with parasympatholytics (propantheline and atropine) and antihistaminics (tripelennamine, diphenhydramine) as regards the analgesic effect (in thermal contact method) were examined by its oral administration with each combined drug to mouse (three assumption cross-over test), and the following effects were found. 1. The increasing order of the parasympatholytics to the analgesic effect of salicylamide is as follows: propantheline>atropine. 2. The increasing order of the antihistaminics to the analgesic effect of salicylamide is as follows: chlorpheniramine>diphenhdramine>tri pelennamine. In the ratio '1 : 1' salicylamide to parasympatholytics and antihistaminics, the analgesic effect of salicylamide was more increase than the other ratio in this study.

The antagonism against clonidine-induced analgesia by ginseng saponin (GS) and the inhibitory effect of GS on the development of clonidine-induced tolerance were evaluated in mice. GS, when administered systemically, intracerebrally and intrathecally, antagonized significantly the analgesic effect of clonidine. GS, when injected intraperitoneally not only inhibited the development of clonidine-induced analgesic tolerance, but also enhanced the analgesic effect of clonidine on the 2nd and 5th day. Naloxone did not antagonize the analgesic effect of clonidine and had no influence on the deveolpment of tolerance of both acute and delayed types. These results indicate that the antagonism against clonidine-induced analgesia and the inhibition of the deveolpment of clonidine-induced tolerance by GS are not mediated by the opioid mechanism.

Loxoprofen-Na (sodium 2-〔4-(2-oxocyclopentylmethyl)pheny)propionate dihydrate) is a potent analgesic drug. We developed loxoprofen-Na plasters to extend duration time of analgesic activity and to reduce side effect on gastrointestinal tract. Analgesic effect of Loxoprofen-Na plasters was investigated. Loxoprofen-Na plaster had good analgesic effect in rat paw pressure test, Tail-flick latency test and acetic acid-induced writhing test. Also, it had anti-inflammatory effect on carrageenan-induced rat hind paw edema. In pharmacokinetic study of Loxoprofen-Na, plasters dosage form showed that plasma drug concentration was prolonged up to 14 hours. So, we can conclude that loxoprofen-Na plasters, when applied on skin, will be a new type of drug for controlling the various local pain or inflammation.
