From the perspective of the definition of pain, pain can be divided into emotional and sensory components, which originate from potential and actual tissue damage, respectively. The pharmacologic treatment of the emotional pain component includes antianxiety drugs, antidepressants, and antipsychotics. The anti-anxiety drugs have anti-anxious, sedative, and somnolent effects. The antipsychotics are effective in patients with positive symptoms of psychosis. On the other hand, the sensory pain component can be divided into nociceptive and neuropathic pain. Non-steroidal anti-inflammatory drugs (NSAIDs) and opioids are usually applied for somatic and visceral nociceptive pain, respectively; anticonvulsants and antidepressants are administered for the treatment of neuropathic pain with positive and negative symptoms, respectively. The NSAIDs, which inhibit the cyclo-oxygenase pathway, exhibit anti-inflammatory, antipyretic, and analgesic effects; however, they have a therapeutic ceiling. The adverse reactions (ADRs) of the NSAIDs include gastrointestinal problems, generalized edema, and increased bleeding tendency. The opioids, which bind to the opioid receptors, present an analgesic effect only, without anti-inflammatory, antipyretic, or ceiling effects. The ADRs of the opioids start from itching and nausea/vomiting to cardiovascular and respiratory depression, as well as constipation. The anticonvulsants include carbamazepine, related to sodium channel blockade, and gabapentin and pregabalin, related to calcium blockade. The antidepressants show their analgesic actions mainly through inhibiting the reuptake of serotonin or norepinephrine. Most drugs, except NSAIDs, need an updose titration period. The principle of polypharmacy for analgesia in case of mixed components of pain is increasing therapeutic effects while reducing ADRs, based on the origin of the pain.

Three phase hollow fiber-liquid phase microextraction (HF-LPME), which is faster, simpler and uses a more environmentally friendly sample-preparation technique, was developed for the analysis of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) in human urine. For the effective simultaneous extraction/concentration of NSAIDs by three phase HF-LPME, parameters (such as extraction organic solvent, pH of donor/acceptor phase, stirring speed, salting-out effect, sample temperature, and extraction time) which influence the extraction efficiency were optimized. NSAIDs were extracted and concentrated from 4 mL of aqueous solution at pH 3 (donor phase) into dihexyl ether immobilized in the wall pores of a porous hollow fiber, and then extracted into the acceptor phase at pH 13 located in the lumen of the hollow fiber. After the extraction, 5 ${\mu}L$ of the acceptor phase was directly injected into the HPLC/UV system. Simultaneous chromatographic separation of seven NSAIDs was achieved on an Eclipse XDB-C18 (4.6 mm i.d. ${\times}$ 150 mm length, 5 ${\mu}m$ particle size) column using isocratic elution with 0.1% formic acid and methanol (30:70) at a HPLC-UV/Vis system. Under optimized conditions (extraction solvent, dihexyl ether; $pH_{donor}$, 3; $pH_{acceptor}$, 13; stirring speed, 1500 rpm; NaCl salt, 10%; sample temperature, $60^{\circ}C$; and extraction time, 45 min), enrichment factors (EF) were between 59 and 260. The limit of detection (LOD) and limit of quantitation (LOQ) in the spiked urine matrix were in the concentration range of 5-15 ng/mL and 15-45 ng/mL, respectively. The relative recovery and precision obtained were between 58 and 136% and below 15.7% RSD, respectively. The calibration curve was linear within the range of 0.015-0.96 ng/mL with the square of the correlation coefficient being more than 0.997. The established method can be used to analyse of NSAIDs of low concentration (ng/mL) in urine.

The systematic approach to pharmacologic treatment is typically to begin with the safest, simplest, and most conservative measures. It has been realized that the more rapidly inflammation is under control, the less likely it is that there will be permanent sequelae. Nonsteroidal anti-inflammatory drugs (NSAIDs) are the mainstay of initial treatment for inflammation. In addition, the slow-acting antirheumatic drugs (SAARDs) and disease-modifying antirheumatic drugs (DMARDs) have efficacy of anti-inflammatory action in children with chronic arthritis. New therapeutic modalities for inflammation, such as etanercept and infliximab, promise even further improvements in the risk/benefit ratio of treatment. It is not typically possible at the onset of the disease to predict which children will recover and which will go on to have unremitting disease with lingering disability or enter adulthood with serious functional impairment. Therefore, the initial therapeutic approach must be vigorous in all children.

A high performance liquid chromatographic method has been developed for the simultaneous analysis of non-steroidal anti-inflammatory drugs in plasma. The simultaneous determination of ibuprofen, fenoprofen and ketoprofen is performed by RP-HPLC with UV detection. The chromatographic system consisted of Spherisorb octyl column$(5{\mu}m)$ ; the mobile phase was $acetonitrile\;-\;0.5\%$ phosphoric acid(55 : 45, v/v) and the detection wavelength was 230nm. Tolmetin was employed as an internal standard. The method described is rapid and simple with sensitivity limits of $2.0{\mu}g/ml$ ibuprofen, $0.5{\mu}g/ml$ fenoprofen and $0.3{\mu}g/ml$ ketoprofen and is suitable for routine clinical and pharmacokinetic studies.

The prescription sheets for outpatients from July 2008 to June 2009 from 7 community pharmacies in Ulsan City were surveyed for the anti-inflammatory drug (AID) prescription pattern. The AID prescription rate of pediatricians and ENT physicians were 30.0% and 34.8%, respectively. The oral steroidal anti-inflammatory drugs (SAIDs) were prescribed as much as 3.9% by pediatricians and 10.3% by ENT physicians. The chiefly prescribed oral SAID was prednisolone in pediatric clinics and methylprednisolone in ENT clinics. Meanwhile the prescription rate of oral non-steroidal anti-inflammatory drug (NSAID) was 22.5% by pediatricians and 21.4% in ENT physicians. The most favorable NSAIDs were propionate derivatives in both clinics. In case of externally-applied SAIDs, the prescription rate of pediatricians was 3.6% and that of ENT physicians was 2.8%. Among them, nasal spray, inhalant and gargle formulations for upper respiratory infection (URI) treatment occupied 35.8% of externally-applied SAIDs in pediatric clinics and 59.7% in ENT clinics. Further, it was observed that ENT physicians favored much stronger SAIDs in Group III of ATC classification (75.4% of externally-applied SAIDs) than pediatricians (49.2%). In the survey of AID combination rate, pediatric clinics showed much lower rate (1.4% of total AID prescriptions) than ENT clinics (7.5%). Among them, the combination rate of oral SAID and oral NSAID by ENT physicians (52.2% of total AID combinations) was much higher than pediatricians (36.6%), which might be over-prescription of AID agents. In conclusion, the AID prescription rate as well as AID combination rate, especially in SAID prescriptions, was much higher in ENT than pediatric clinics, which implies the higher confidency on AID drugs of ENT physicians even though the severity of patient's symptom could be considered.

A various ${\alpha}$-arylmethylpropionic acids(profen) have been widely used as non-steroidal anti-inflammatory drugs for the relief of acute and chronic rheumatoid arthritis and osteoarthritis, as well as for other connective tissue disorders and pains. Example is fenoprofen, ibuprofen, ketoprofen, and naproxen. All are chiral and, except for naproxen and ibuprofen, are marketed in racemic form. Enantioseparations of profens have been of considerable interest becaus their anti-inflammatory and analgesic effects have been attirbuted almost exclusively to their (S)-enantiomer. (omitted)

Two dogs were presented with melena, vomiting and depression after accidental swallowing of candy form of Strepsils (flurbiprofen), which is one of non-steroidal anti-inflammatory drugs used in human medicine for controlling a sore throat. These dogs had common signs of anemia induced by gastrointestinal ulceration and hemorrhage with azotemia and leukocytosis. The dogs were treated with blood transfusion, fluid therapy, proton-pump inhibitor, antiemetics, mucus protectant and antibiotic. Although most of clinical signs of two dogs were resolved, azotemic problem with evidence of renal injury have remained.

Objective : This study describes a case of urticarial drug eruption assumed to be caused by non-steroidal anti- inflammatory drugs (NSAIDs) treated with oriental medicine and acupuncture. Methods : We studied the case of 20-years-old drug eruption patient. The patient complained of urticaria, angioedema, itching and burning sensation after taking NSAIDs. The indications for NSAIDs prescribed were common cold symptom and sore throat. For diagnosis, blood test and urinalysis were done. For treatment, acupuncture and herbal-medicine treatment were applied. Results : The patient of this report were examined for 13 days. The radiological finding was within normal limits. The WBC, neutrophil, lymphocyte and eosinophil level normalized during admission. After 3 days, itching and wheal reaction of whole body disappeared except facial symptom. The angioedema, itching and wheal reaction in the face was almost improved in the 4th day after discharge. Conclusions : We may expect that the oriental medical therapy improves the urticarial drug eruption caused by NSAIDs.

Recent studies suggest that inflammatory events are implicated in a variety of human diseases including cancer and neurodegenerative diseases. and non-steroidal anti-inflammatory drugs have beneficial effects in treatment or prevention of these disorders. It has been reported that expression of cyclooxygenase (COX)-2 and nitric oxide synthase and subsequent production of prostaglandin (PG) and nitric oxide (NO). respectively are elevated in many inflammatory disorders.
