  • A drug delivery system(DDS) for practically insoluble meloxicam was developed and evaluated by dissolution study. A novel DDS is two layered system, where the first layer is consisted of gas-forming agent for an immediate release and the second layer is composed of metolose SR(HPMC) for sustained release. This bilayered tablets were manufactured by using manual single punch machine. The results of dissolution study showed an initial burst release followed by sustained release for the experimental period time. From a pharmaceutical point of view, the designed DDS for meloxicam would be informative system in terms of poorly soluble analgesic medicines.

  • Previously, we have reported that the butanol fraction of the head of Panax ginseng had significant gastroprotective activity on gastritis and gastric ulcer models of rats. Considering the safety of the fraction for development of new anti-ulcerative agent or food supplement, general pharmacological study was carried on. The fraction was revealed that have no influence on spontaneous activity, phenobarbital-induced sleeping time, rotarod test, body temperature, gastro-intestinal motility, respiration and blood pressure. The fraction showed weak analgesic action in writhing syndrome and did not show any sign of acute toxicity in mice.

  • Ligularia stenocephala has been widely used as a traditional medicine for the treatment of lots of diseases such as asthma, arthritis, and jaundice. In this study, we evaluated the anti-nocicepitve activities of methanolic extract of L. stenocephala (MLS) using various pain models including thermal nociception as well as chemical nociception methods. MLS showed significant increase in latency time in the tail immersion test and hot-plate test. In addition, the number of acetic acid-induced abdominal constrictions was decreased by MLS. MLS also attenuated paw licking time in the formalin test. The combination test using naloxone revealed that the anti-nociceptive properties of MLS was not associated with opioid receptor activation. The present results demonstrate that MLS may possibly used as valuable analgesic agent for the treatment of nociceptive pain.

  • The first clinical application of nitrous oxide ($N_2O$) was in 1844, by an American dentist named Horace Wells who used it to control pain during tooth extraction. Since then, $N_2O$ has shared a 170-year history with modern dental anesthesia. $N_2O$, an odorless and colorless gas, is very appealing as a sedative owing to its anxiolytic, analgesic, and amnestic properties, rapid onset and recovery, and, in particular, needle-free application. Numerous studies have reported that $N_2O$ can be used safely and effectively as a procedural sedation and analgesia (PSA) agent. However, $N_2O$ can lead to the irreversible inactivation of vitamin B12, which is essential for humans; although rare, this can be fatal in some patients.

  • Cyperus rotundus L. (Cyperaceae) has been used as an analgesic and antiiflammatory agent and in the treatment of menstrual disorder in folk remedies. Cyperi Rhizomata, processed and unprocessed, were extracted with methanol and fractionated with petroleum ether, chloroform. Butanol, water. The effect of unprocessed Cyperi Rhizoma and processed Cyperi Rhizoma on $CCl_4$ induced lipid peroxidation and hepatotoxity have been tested in rats. BuOH. Water fractions of unprocessed Cyperi Rhizome enhanced the inhibition of antilipid peroxidative effects in liver lipid. In chemical parameters obtained from serum analysis. Butanol fraction of unprocessed Cyperi Rhizoma showed significant decrease in hepatotoxicity. In result, unprocessed Cyperi rhizoma has significant antilipid peroxidative effect and hepatoprotective activity.

Cyperi Rhizomata, processed and unproces sed, were extracted with MeOH and fractionated with petroleum ether (Pet. Ether), $CHCl_3$, BuOH, water. In order to investigate the effects of their fractions on kidney function of acute renal failure rats induced by $HgCl_2$ urinary volume, BUN, Creatinine, Uric acid were determined. The diuretic effect of processed Cyperi Rhizoma was significantly increased in renal failure rats, on serum chemical parameters, the significant inhibition of BUN (blood urea nitrogen) of processed Cyperi Rhizoma was revealed.

  • Capsaicin and analogues are valuable analgesic agents when administered to mammals. including humans. However. their pungency. hypothermia and the effects on the cardiovascular and respiratory systems through their general activation of primary afferents severely limit their use. So competitive antagonists have been pursued as a novel pharmacological agent for analgesics. rather than agonists. We have identified a new class of potent and selective vanilloid receptor (VR) antagonists. (omitted)

  • Background: Nefopam is a centrally acting non-opioid analgesic agent. Its analgesic properties may be related to the inhibitions of monoamine reuptake and the N-methyl-D-aspartate (NMDA) receptor. The antinociceptive effect of nefopam has been shown in animal models of acute and chronic pain and in humans. However, the effect of nefopam on diabetic neuropathic pain is unclear. Therefore, we investigated the preventive effect of nefopam on diabetic neuropathic pain induced by streptozotocin (STZ) in rats. Methods: Pretreatment with nefopam (30 mg/kg) was performed intraperitoneally 30 min prior to an intraperitoneal injection of STZ (60 mg/kg). Mechanical and cold allodynia were tested before, and 1 to 4 weeks after drug administration. Thermal hyperalgesia was also investigated. In addition, the transient receptor potential ankyrin 1 (TRPA1) and TRP melastatin 8 (TRPM8) expression levels in the dorsal root ganglion (DRG) were evaluated. Results: Pretreatment with nefopam significantly inhibited STZ-induced mechanical and cold allodynia, but not thermal hyperalgesia. The STZ injection increased TRPM8, but not TRPA1, expression levels in DRG neurons. Pretreatment with nefopam decreased STZ-induced TRPM8 expression levels in the DRG. Conclusions: These results demonstrate that a nefopam pretreatment has strong antiallodynic effects on STZ-induced diabetic rats, which may be associated with TRPM8 located in the DRG.
