In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions.They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins.

The receptor is activated by TRYPSIN, which cleaves off the N-terminal peptide from the receptor. The new N-terminal peptide is a cryptic ligand for the receptor.

The single primary branch bifurcates sending a peripheral process to carry sensory information from the periphery and a central branch which relays that information to the spinal cord or brain.Fentanyl: A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist. Fentanyl is also used as an adjunct to general anesthetics, and as an anesthetic for induction and maintenance. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1078)Oxycodone: A semisynthetic derivative of CODEINE.Electromyography: Recording of the changes in electric potential of muscle by means of surface or needle electrodes.Double-Blind Method: A method of studying a drug or procedure in which both the subjects and investigators are kept unaware of who is actually getting which specific treatment.Receptors, N-Methyl-D-Aspartate: A class of ionotropic glutamate receptors characterized by affinity for N-methyl-D-aspartate. NMDA receptors have an allosteric binding site for glycine which must be occupied for the channel to open efficiently and a site within the channel itself to which magnesium ions bind in a voltage-dependent manner. The positive voltage dependence of channel conductance and the high permeability of the conducting channel to calcium ions (as well as to monovalent cations) are important in excitotoxicity and neuronal plasticity.Meperidine: A narcotic analgesic that can be used for the relief of most types of moderate to severe pain, including postoperative pain and the pain of labor. Prolonged use may lead to dependence of the morphine type; withdrawal symptoms appear more rapidly than with morphine and are of shorter duration.Bupivacaine: A widely used local anesthetic agent.Analgesia, Epidural: The relief of pain without loss of consciousness through the introduction of an analgesic agent into the epidural space of the vertebral canal. It is differentiated from ANESTHESIA, EPIDURAL which refers to the state of insensitivity to sensation.Rats, Wistar: A strain of albino rat developed at the Wistar Institute that has spread widely at other institutions. This has markedly diluted the original strain.

  • While some classes of drugs, such as the narcotic agonist/antagonist drugs bupronophine, nalbuphine, and pentazocine, and the selective COX-2 inhibitors celecoxib and rofecoxib represent advances in reduction of adverse effects, they are still not fully suitable for long-term management of severe pain.

  • In the present study, we have analyzed the chemical composition of M. tomentosa leaves and branches and examined the possible analgesic effects of some fractions (hexane, dichloromethane, ethyl acetate and butanol) and of one isolated component, arjunolic acid ( 5 ) using the writhing and formalin tests in mice.

  • Analgesic properties of two aminoadamantanes, amantadine (20 mg/kg) and hemantane (20 mg/kg), which were uncompetitive NMDA receptor antagonists, were assessed in rodent models of pain induced by different pain stimuli (tail-flick test, acetic twitches test in mice and formalin test in rats). (scirp.org)
  • Hemantane was more effective than amantadine for relieving pain produced by inflammation owing to its pronounced anti-inflammatory activity: only hemantane decreased the amount of acetic twitches in mice that received drugs orally and was effective in the tonic phase of formalin pain in rats. (scirp.org)
  • In order to study nervous system contributions to the condition, a physiological model of urinary bladder pain is used in mice and rats. (jove.com)
  • To determine if the stress-induced analgesic response is differentially expressed in visceral versus somatic pain states, we studied the effects of a mild social stressor in either acute visceral or somatic pain states in mice. (sigmaaldrich.com)
  • Compared with mice tested alone, the presence of a stranger produced a dramatic opioid-dependent reduction in pain behavior associated with visceral but not somatic pain. (sigmaaldrich.com)
  • If a significant amount of medication for breakthrough pain is already being given, the baseline dose of sustained-release analgesic medication should be increased. (aafp.org)
  • 6,Thus, chronic pain can be thought of as consisting of two components: a relatively constant component (baseline pain) and an intermittent component superimposed on the baseline pain (breakthrough pain). (cpmission.com)
  • Although baseline opioid use was not a requirement, whatever amount of medication (or no medication) the patient was on for baseline pain was required to be a stable dose for 2 or more days. (oncolink.org)
  • 96% of the episodes of breakthrough pain occurred in the same location as the baseline pain. (oncolink.org)
  • The biology of prostate cancer is heterogeneous, with expected survival depending on performance status, presence of visceral metastases, baseline prostate-specific antigen (PSA), advanced primary Gleason sum, baseline hemoglobin, lactate dehydrogenase, albumin, and alkaline phosphatase ( 3 , 4 ). (aacrjournals.org)
  • The aim of the current analysis is to develop a multivariate prognostic model, based on the TAX327 trial, to investigate the independent prognostic significance of novel prognostic variables, such as pretreatment PSA kinetics, the presence of pain, number of metastatic sites, and the type of disease progression at baseline, in addition to traditional prognostic markers. (aacrjournals.org)
  • This study was designed to assess the effect of the addition of parecoxib to a multimodal perioperative analgesic regimen given to women undergoing minor day stay gynaecological procedures. (thefreelibrary.com)
  • Opioid rotation can be used if pain can no longer be controlled on a specific regimen. (aafp.org)
  • Other drugs, notably the tricyclic antidepressants and anti-epileptic agents, such as gabapentin, have been used to relieve pain, particularly neurologic pain, but are not routinely classified as analgesics. (encyclopedia.com)
  • A secondary approach might introduce medications used to treat nerve pain like the anti-convulsants (that can calm the nervous system) or the tricyclic analgesics (that can also reduce nervous system sensitivity). (healthcentral.com)
  • Variability in pain-related traits (or "phenotypes")-experimental pain sensitivity, propensity to develop painful pathologies, and sensitivity to analgesic manipulations-has long been appreciated, although empirical validation of such variability is somewhat limited. (pnas.org)
