Claims 10 A Therapeutic Injectable analgesic pharmaceutical Composition for intra-muscular administration comprising the following ingredients : Nimesulide : 2. In general qualitative terms nimesulide exhibits the usual adverse events associated with NSAIDs gastrointestinal, dermatological and neurological. Pharmacokinetic PropertiesAfter oral administration of nimesulide 50 to mg to healthy oxygenation volunteers, peak serum concentrations of 1. Recently, we have found that kainate-induced excitotoxicity, synthesis the subsequent oxidative damage, is significantly reduced by the administration of nimesulide at a clinically relevant dose in the rat hippocampus [ 19 ]. In syntheses, nimesulide suspension, granules and suppositories are more effective than placebo and are at least as effective as paracetamol, diclofenac, naproxen, lysine acetylsalicylate, mefenamic acid, ketoprofen and dipyrone in reducing the pain, inflammation and synthesis associated with respiratory tract infection, postoperative pain and musculoskeletal injury.

Pharmacodynamic PropertiesThe anti-inflammatory, analgesic and antipyretic syntheses of nimesulide, a nonsteroidal anti-inflammatory synthesis NSAID of the sulfonanilide class, have been demonstrated in a number H phosphonate synthesis reactions experimental models and in numerous clinical trials.

Nimesulide has exhibited Report a number to the tps similar to or greater than that of indomethacin, diclofenac, piroxicam and ibuprofen in standard animal models of inflammation such as carrageenin-induced rat paw oedema and inflammation, ultraviolet lightinduced erythema in guinea-pigs and Powerpoint presentation on bolivia arthritis in rats.

Add to the mixture obtained 10 g of Nimesulide in small amounts at a time and stirred till completely dissolved. The Injectable Analgesic composition, according to the present invention, on preliminary animal and preclinical trials has been shown to possess marked analgesic activity. Further it has been found to be non-toxic even on repeated applications at the same site. No incidence of tissue necrosis or any other side effect was observed. This analgesic composition is very effective and useful for the treatment of acute painful conditions like post-operative trauma, pain associated with cancer, sports injuries and the like. It was found that free radical generation is associated with excitatory amino acid-induced brain injury [ 14 ]. Kainate has been shown to generate free radicals when added in vitro to rat cerebellar cell cultures [ 15 ] and in gerbil brain, following its systemic administration [ 16 ]. Also, reactive oxygen species were detected when kainate was added to isolated synaptoneurosomes derived from rat cerebral cortex [ 17 ]. Furthermore, it was demonstrated previously [ 18 ] that the addition of kainate to mouse disrupted brain cells caused a concentration-dependent increase in lipid peroxidation. Recently, we have found that kainate-induced excitotoxicity, with the subsequent oxidative damage, is significantly reduced by the administration of nimesulide at a clinically relevant dose in the rat hippocampus [ 19 ]. In addition, we also found a marked neuroprotective effect of nimesulide against hippocampal neuronal damage following global cerebral ischemic brain damage in gerbils, a type of injury in which excitotoxicity plays a key role [ 20 ]. Given that the effects of nimesulide reducing oxidative damage in vivo might be attributed to its direct antioxidant properties, the aim of the present study was to determine whether nimesulide could attenuate the oxidative damage seen after the in vitro exposure of disrupted brain cell homogenates to kainate. The drug is almost completely biotransformed into 4-hydroxy-nimesulide in both free and conjugated forms and this metabolite appears to contribute to the anti-inflammatory activity of the compound. Peak concentrations of 4-hydroxy-nimesulide ranged from 0. The elimination half-life of 4-hydroxy-nimesulide ranges from 2. The pharmacokinetic profile of nimesulide is not significantly altered in children, elderly volunteers and patients with moderately impaired renal function [creatinine clearance 1. Slight accumulation of 4-hydroxy-nimesulide was noted in patients with moderate renal impairment; however, the clinical significance of this finding is unknown. In these indications, nimesulide is more effective than placebo and is at least as effective as therapeutic dosages of other NSAIDs, including piroxicam, ketoprofen, naproxen, etodolac, mefenamic acid, diclofenac, niflumic acid, fentiazac, feprazone and flurbiprofen. Nimesulide therapy was characterised by a rapid onset of analgesia and symptomatic relief in studies where a significant difference in clinical efficacy between active treatments was observed. However, most of these studies evaluated small numbers of patients and were probably too small to identify any small differences in effectiveness. In children, nimesulide suspension, granules and suppositories are more effective than placebo and are at least as effective as paracetamol, diclofenac, naproxen, lysine acetylsalicylate, mefenamic acid, ketoprofen and dipyrone in reducing the pain, inflammation and fever associated with respiratory tract infection, postoperative pain and musculoskeletal injury. TolerabilityNimesulide has been well tolerated by both young and elderly adults and children in 2 large postmarketing surveillance surveys. As with other NSAIDs, the most common adverse effects are gastrointestinal disturbances epigastralgia, heartburn, nausea, diarrhoea and vomiting; 5.

Add 5 g of Nimesulide in small increments and stir till completely dissolved. Make up the volume to ml with Ethyl oleate and filter through 0. Add to the mixture obtained 10 g of Nimesulide in small amounts at a time and stirred till completely dissolved. The Injectable Analgesic composition, according to the present invention, on preliminary animal and preclinical trials has been shown to possess marked analgesic activity. Further it has been found to be non-toxic even on repeated applications at the same site. High concentrations of nimesulide 0. Conclusions Our results suggest that the neuroprotective effects of nimesulide against kainate-induced oxidative stress in vivo are not mediated through its direct free radical scavenging ability because the concentrations at which nimesulide is able to reduce in vitro kainate excitotoxicity are excessively higher than those attained in plasma after therapeutic doses. Keywords: nimesulide, oxidative stress, kainate excitotoxicity, cyclooxygenase-2, neuroprotection Background Nimesulide N- 4-nitrophenoxy-phenyl -methanesulfonamide is a non-steroidal anti-inflammatory drug with potent anti-inflammatory, antipyretic and analgesic properties which is well tolerated gastrointestinally [ 1 ]. Nimesulide is considered a selective cyclooxygenase-2 COX-2 inhibitor [ 2 , 3 ]. Although inhibition of prostanoids synthesis is a key effect of this drug, various non-prostaglandin mechanisms have been proposed to explain its mode of action: inhibition of 1 histamine release and activity [ 4 ], 2 cytokine release [ 5 ], 3 platelet-activating factor synthesis [ 6 , 7 ] and 4 phosphodiesterase type IV activity [ 9 ]. Maffei-Facino and co-workers [ 11 ] demonstrated the direct free radical scavenging activity of nimesulide. Kainic acid 2-carboxycarboxymethylisopropenylpyrrolidine is a non-degradable analog of glutamate isolated from the seaweed Digenea simplex with potent neuroexcitatory and neurotoxic properties [ 12 ]. Nimesulide therapy was characterised by a rapid onset of analgesia and symptomatic relief in studies where a significant difference in clinical efficacy between active treatments was observed. However, most of these studies evaluated small numbers of patients and were probably too small to identify any small differences in effectiveness. In children, nimesulide suspension, granules and suppositories are more effective than placebo and are at least as effective as paracetamol, diclofenac, naproxen, lysine acetylsalicylate, mefenamic acid, ketoprofen and dipyrone in reducing the pain, inflammation and fever associated with respiratory tract infection, postoperative pain and musculoskeletal injury. TolerabilityNimesulide has been well tolerated by both young and elderly adults and children in 2 large postmarketing surveillance surveys.

Withdrawal rates associated with short term up to 30 days nimesulide treatment range from 1. Available data indicate that the gastrointestinal tolerability of nimesulide in adults and children is similar to that of other NSAIDs. The rate of endoscopically verified gastroduodenal irritation with nimesulide appears to be similar to that with placebo and diclofenac, and less than that with indomethacin. Dosage and AdministrationThe usual oral and rectal dosages of nimesulide in adults are and mg twice daily, respectively. The drug is contraindicated in patients with active peptic ulcer disease or moderate to severe hepatic impairment. Nimesulide is generally well tolerated in the elderly and patients with moderate renal insufficiency; however, caution should be used in this group of patients.
