Abstract
The inflammatory mediators prostaglandin E2 (PGE2) and interleukin-1 beta (IL-1 beta) play critical roles in the inflammatory process leading to alveolar bone and connective tissue loss in periodontal disease. Data from a previously published 6-month clinical study demonstrated that twice daily use of 0.1% ketorolac tromethamine oral rinse prevented alveolar bone loss in adults with periodontitis. We further analyzed data from this study to examine the relationship between PGE2. IL-1 beta and bone loss. Patient mean PGE2 and IL-1 beta levels in gingival crevicular fluid (M-GCF) measured throughout the course of the study were directly compared to the maximum amount of alveolar bone height loss observed at a single study site in each patient. The maximum amount of bone loss measured was chosen for the analysis since the pattern of bone loss was clearly episodic in nature. A statistically significant correlation (r = 0.73, p = 0.001) exists between M-GCF PGE2 concentration and the maximum amount of bone height lost at individual patient study sites. The correlation between M-GCF IL-1 beta concentration and maximum bone height lost is also statistically significant (r = 0.66, p = 0.005). Over the 6-month duration of the study, both PGE2 and IL-1 beta were coordinately expressed in the placebo treatment group as reflected in the significant correlation between M-GCF concentrations of the 2 mediators (r = 0.81, p < 0.001). Treatment of patients with 0.1% ketorolac tromethamine twice daily for 6 months resulted in reductions of PGE2 in GCF and a negligible correlation between M-GCF PGE2 and M-GCF IL-1 beta (r = 0.42, p = 0.088). This lack of a strong association between the 2 mediators in the ketorolac treatment group provides a direct biochemical readout of the anti-inflammatory efficacy of ketorolac tromethamine oral rinse in patients with periodontitis. Further studies are warranted to determine the full diagnostic potential of M-GCF levels of PGE2 and IL-1 beta for predicting risk of alveolar bone loss in patients with periodontitis and monitoring periodontal therapy effectiveness.

Abstract
BACKGROUND Nonsteroidal anti-inflammatory drugs (NSAIDs) cause substantial morbidity and mortality from upper gastrointestinal tract disease. Ketorolac tromethamine has been singled out as an NSAID with a distinct gastrotoxicity profile. Calcium channel blockers, a class of antihypertensive drugs, have also been found to increase the risk of gastrointestinal tract bleeding. METHODS We identified 1505 patients hospitalized because of upper gastrointestinal tract bleeding and/or perforation, and we randomly sampled 20,000 controls in the source population. RESULTS The adjusted relative risk (RR) for upper gastrointestinal tract bleeding and/or perforation in NSAID users compared with nonusers was 4.4 (95% confidence interval [CI], 3.7-5.3). The risk increased with higher daily doses. Ketorolac presented the highest risk (RR, 24.7; 95% CI, 9.6-63.5) and piroxicam ranked second (RR, 9.5; 95% CI, 6.5-13.8). Ketorolac was 5 times more gastrotoxic than all other NSAIDs (RR, 5.5; 95% CI, 2.1-14.4). The excess risk with ketorolac was observed with both oral and intramuscular administration and was already present during the first week of therapy. Among the various antihypertensive drug classes, beta-blockers were associated with the lowest relative risk (RR, 1.0; 95% CI, 0.7-1.4), and current use of calcium channel blockers with the highest (RR, 1.7; 95% CI, 1.3-2.1). The association with calcium channel blockers declined when adjusting for various markers of comorbidity (RR, 1.4; 95% CI, 1.1-1.8). Past use of calcium channel blockers was also associated with an increased risk (RR, 1.5; 95% CI, 1.3-1.8). CONCLUSIONS The excess risk of major upper gastrointestinal tract complications associated with outpatient use of ketorolac suggests an unfavorable risk-benefit assessment compared with other NSAIDs. More data are required to reduce the uncertainty about the apparent small increased risk of upper gastrointestinal tract bleeding in patients using calcium channel blockers.

Abstract
Ketorolac tromethamine (KT) is a non-steroidal drug with potent analgesic and anti-inflammatory activity and is absorbed rapidly (Tmax < 1.0 h) with an efficiency > 87% following oral and intramuscular administration. The plasma half-life of ketorolac ranges from 1.1 to 6.0 h. Its oral bioavailability is estimated to be 80%. Ketorolac has been found 36 times more potent than phenylbutazone, approximately twice as potent as indomethacin, and three times more potent than naproxen in suppressing carrageenan-induced paw oedema in rat. In this study, microcapsules of KT were prepared by means of coacervation-phase separation technique induced by the addition of non-solvent, and release rates from microcapsules were studied. Eudragit S100 was used as the coating material. Coacervation was achieved by the addition of cyclohexane at 2 ml/min at 25 degrees C and 1:4 solvent: non-solvent ratio was used. The microcapsules were washed with cyclohexane to harden the wall and dried at room temperature. Microcapsules with core:wall ratio of 1:1 and 1:2 were prepared and the particles obtained by sieving with an average diameter of 177-500 microns were used. The yield was calculated and the release properties of KT were investigated by USP XXII paddle method and using UV spectrophotometry at 318 and 323 nm.

Abstract
Transcorneal permeation of ketorolac from oil based ocular drops and ophthalmic ointments was studied in vitro, using goat cornea. Cumulative (%) permeation of ketorolac through cornea, was found to be maximum with 0.2% (w/v) ketorolac drops in sesame oil followed by formulations in corn oil and soyabean oil. Ketorolac 1% (w/v) drops in castor oil increased the quantity permeated but cumulative (%) permeation was less. Permeation profiles of ketorolac were in consistence with the partition characteristic of drug between oil and aqueous phase. Formulations favouring corneal permeation of ketorolac increased corneal hydration. Addition of benzyl alcohol, a preservative, to oil drops reduced permeation of ketorolac and corneal hydration indicating possible protective effect of benzyl alcohol against corneal damage. Permeation studies on ointment formulations containing either ketorolac acid or ketorolac tromethamine salt indicated better permeation for formulation containing ketorolac tromethamine aqueous solution. Thus for better transcorneal permeation, ketorolac 0.2% (w/v) drops, formulated in sesame oil, containing 0.5% v/v benzyl alcohol and ophthalmic ointment containing 0.5% (w/w) ketorolac tromethamine in dissolved state appear suitable.

Abstract
OBJECTIVE The purpose of this study was to determine the effect of ketorolac tromethamine or placebo on the neuromuscular blockade induced by an infusion of atracurium in isoflurane-anesthetized dogs. DESIGN Randomized, controlled trial. ANIMALS Six healthy, adult mixed-breed dogs (five female, one male) weighing 24.8 +/- 2.8 kg. METHODS Dogs were studied on two occasions with a minimum of 7 days between studies. Dogs were induced with 5% isoflurane in oxygen and maintained with 1.6 x minimum alveolar concentration (MAC) end-tidal isoflurane. Neuromuscular blockade was assessed using the train-of-four response. Once 50% depression of the first twitch (T1) was achieved, the atracurium infusion rate was held constant for 30 minutes. Then ketorolac, 0.5 mg/kg, or the same volume of placebo (0.9% sodium chloride solution) was administered intravenously and the atracurium infusion maintained for an additional 60 minutes. Before and at 2, 5, 10, 15, 30, and 60 minutes after ketorolac or placebo, the percent depression of T1 and the fourth twitch to the first twitch (T4/T1) ratio were recorded. The atracurium infusion was discontinued and the time for T1 to recover from 50% to 75% of its original value was recorded. At 75% T1, edrophonium, 0.5 mg/kg intravenously, was administered to antagonize the residual blockade. RESULTS There was no significant difference in T1%, T4/T1 ratio, or recovery time after ketorolac administration compared with placebo. CONCLUSIONS Ketorolac, 0.5 mg/kg intravenously, has no significant effect on either atracurium-induced neuromuscular blockade or recovery time for T1 in isoflurane-anesthetized dogs. CLINICAL RELEVANCE The concurrent use of atracurium should not be a contraindication for the administration of ketorolac for intraoperative or postoperative analgesia.

Abstract
Locally injected steroids are used to treat inflammatory conditions, in spite of the complications associated with their use. Ketorolac tromethamine, an injectable nonsteroidal anti-inflammatory drug, has not previously been evaluated for treatment of musculoskeletal inflammatory conditions via local administration. Eighty Achilles tendons of rabbits were traumatized in a controlled fashion. At the time of trauma, a single dose of ketorolac (1, 3, or 5 mg/kg) or normal saline was administered peritendinously. Three days later, the tendons were harvested and examined histologically to evaluate the degree of inflammation present in the tissue. No statistically significant difference was found between the experimental and control groups. The authors conclude that locally injected ketorolac does not prevent the onset of an inflammatory process.

Abstract
In vitro transcorneal permeation of ketorolac tromethamine from 0.5% w/v solutions containing equimolar (0.02 M) concentrations of citrate (pH 6.5), phosphate (pH 6.5 and 7), citrate-phosphate (pH 7) and borate (pH 7) buffers was studied using goat cornea. Cumulative % permeation was maximum with phosphate buffered drops of pH 6.5. The effect of pH and ionic strength on permeation of ketorolac tromethamine from buffered (phosphate) drops was next investigated. Cumulative % permeation of ketorolac tromethamine from buffered drops was pH dependent being maximum at pH 4.5. Adjustment of ionic strength of drops to 0.2 resulted in decreased permeation of drug. Permeation of ketorolac tromethamine from unbuffered drops of varying pH and ionic strength 0.2 was also pH dependent and was maximum at pH 4.5. Buffered drops of pH between 4.5-5.5, ionic strength 0.2, provided better permeation of drug compared to unbuffered drops of same pH and ionic strength. Above pH 6.5 unbuffered drops showed better permeation than buffered drops. Increase in molarity of phosphate buffer (pH 4.5) used in making drops, between 0 to 0.15 M increased permeation. Aqueous drops of ketorolac tromethamine formulated in 0.15 M phosphate buffer of pH 4.5 and ionic strength 0.2 showed maximum cumulative % permeation in vitro. Considering lacrimation induced drug loss in vivo, by buffer of high concentration, ketorolac tromethamine drops formulated in buffer of low molarity, pH 4.5 and ionic strength 0.2 appear suitable.

Abstract
BACKGROUND The optimal method to achieve analgesia after inguinal hernia repair in children is unknown. This study compared the analgesic efficacy, adverse events, and the costs associated with supplementation of local anesthesia (infiltration of the wound) with either intravenous ketorolac or caudal analgesia in children having inguinal hernia repair. METHODS With parental consent and institutional review board approval, children aged 2-6 yr having elective, outpatient inguinal hernia repair were studied in this randomized, single-blinded investigation. Anesthesia was induced by inhalation with nitrous oxide and halothane or intravenously with propofol. Anesthesia was maintained with nitrous oxide and halothane. Patients were randomly assigned to receive caudal analgesia (1 ml/kg 0.20% bupivacaine with 1/200,000 epinephrine) or intravenous ketorolac (1 mg/kg) immediately after induction of anesthesia. Both groups received field blocks with 0.25% bupivacaine administered by the surgeon under direct vision during operation. Patients were assessed for 24 h. In-hospital pain was assessed using a behavior-based pain score. Parents assessed pain with a visual linear analog pain scale with anchors of 0 (no pain) and 100 (worst pain imaginable). RESULTS The authors studied 164 children, with 84 patients in the ketorolac group. The groups had similar demographic data. In-hospital analgesic requirements and pain scores were almost identical in both groups. Pain at home was significantly less in the ketorolac group, with visual linear analog pain scale scores of 10 (0-80) compared with 20 (0-80) (median [range]) for ketorolac versus caudal (P = 0.002 by the Mann-Whitney U test). The ketorolac group also had a lower incidence of vomiting, ambulated more rapidly, and micturated earlier (P < 0.05). CONCLUSION The use of intravenous ketorolac to supplement local anesthesia infiltrated by the surgeon during pediatric inguinal hernia repair is superior to supplementation with caudal analgesia.

Abstract
BACKGROUND AND OBJECTIVE Mydriatics and antiprostaglandins are routinely applied preoperatively to facilitate the aspiration of cortical material during extracapsular cataract surgery and to prevent intraoperative miosis. Unfortunately, the ideal antiprostaglandin has yet to be introduced. This study represents the first prospective, case-controlled, randomized, masked, clinical trial comparing the efficacy of oral ketorolac tromethamine (KT) with the efficacy of topical flurbiprofen sodium (FS) and a placebo (normal saline) in maintaining intraoperative mydriasis without adrenaline in the irrigation solution. PATIENTS AND METHODS Sixty-three patients, undergoing extracapsular cataract extraction with posterior chamber intraocular lens implantation, were randomly divided into three equal groups. Group 1 received 20 mg of oral KT 2 hours prior to surgery, group 2 received 0.03% FS topical solution at the recommended dosage, and group 3 received topical normal saline in a regimen identical to that of group 2. Identical mydriatics were used in both groups. The patients' pupils were measured at five stages of surgery. RESULTS The mean pupillary diameters at each surgical stage were greater in group 1 than in group 2; however, the difference was not statistically significant. The pupils in group 3 were significantly smaller than those of group 1 or group 2 (P < .05). No systemic toxicity to KT was observed. Moreover, the need for additional postoperative analgesics was significantly greater in groups 2 and 3. CONCLUSIONS Oral KT is safe, convenient, and as effective as topical FS, and has the added advantage of reducing postoperative pain.

Abstract
Analgesia with nonsteroid antiinflammatory drugs (NSAID) becomes a pressing problem today. One such drug is ketorolak tromethamine (KT), characterized by expressed analgesic activity comparable with that of opioid analgesics morphine or promedol. Our purpose was to assess KT efficacy in analgesia performed by different methods, including analgesia controlled by the patient (ACP) after surgery. In medium severe and strong pain KT was used in group I (n = 60) "as needed" in a dose of 30 mg up to 3-4 times a day, in group 2 (n = 12) by the ACP method, in group 3 (n = 16) KT was incessantly infused in a daily dose of up to 120 mg, and in group 4 (n = 11) KT was injected 3-4 times a day in a dose of 30 mg in combination with morphine ACP. The results indicate a high efficacy of KT: 83% after a single injection. Combined use of KT and promedol decreased the dose by 40-50%. Side effects were observed in 15% of patients: most often it was a sense of fever and sweating (in 4% of patients), nausea and vomiting (in 2%), insomnia (in 2%). ACP and planned injections in a daily dose of 90-120 mg is the optimal method of analgesia in patients after extensive surgical interventions.

Abstract
STUDY OBJECTIVE To compare ketorolac tromethamine with morphine for pain management after major abdominal surgery. DESIGN Double-blind, randomized study. SETTING Hospital recovery room and postoperative surgical unit. PATIENTS One hundred ninety-one patients with at least moderate pain after major abdominal surgery. INTERVENTIONS Patients received ketorolac by patient-controlled analgesia (PCA) bolus alone (Ket B), ketorolac by bolus plus infusion (Ket I), or morphine by PCA bolus (morphine), with injectable morphine available for supplementation. MEASUREMENTS AND MAIN RESULTS Levels of sedation, pain intensity, pain relief, and adverse events were recorded at baseline, at 2, 4, and 6 hours, and at termination. Supplemental morphine was required by 71% of Ket B patients, 67% of Ket I patients, and 38% of morphine patients (p < or = 0.001 for Ket B vs morphine). Although patients receiving ketorolac required more supplemental morphine than the morphine group (6.0 mg Ket I, 6.2 mg Ket B, 4.0 mg morphine), there was a large morphine-sparing effect in both ketorolac groups (total morphine 6.0 mg Ket I, 6.2 mg Ket B, 33.3 mg morphine). Overall pain relief scores were similar for morphine and Ket I groups, and were lower for Ket B than for morphine (p = 0.002). There were no differences among groups in numbers of patients with adverse events. CONCLUSION Ketorolac may be effective when administered by PCA device, and has a clear morphine-sparing effect.

Abstract
OBJECTIVE To compare the effects of topical 0.5% ketorolac tromethamine ophthalmic solution (Acular, Allergen Pharmaceuticals, Irvine, Calif) with topical 0.03% flurbiprofen sodium ophthalmic solution (Ocufen, Allergen Pharmaceuticals) on the inhibition of surgically induced miosis during phacoemulsification cataract surgery. DESIGN One hundred eighteen patients were prospectively randomized to receive 0.5% topical ketorolac or 0.03% topical flurbiprofen at 3 preoperative intervals. The flurbiprofen-treated group served as the control group. The surgeon was masked as to patient selection. Horizontal pupillary diameter measurements were obtained at the start of surgery, just before phacoemulsification, before lens implantation, and after lens implantation. RESULTS Mean horizontal pupillary diameter measurements for both medications were similar at the start of surgery. However, a consistent trend of larger pupillary diameter was seen in all subsequent surgical intervals in the ketorolac-treated group. Changes from baseline measurements also indicated a more significant inhibition of miosis at all subsequent intervals, and a more stable mydriasis throughout the procedure in the ketorolac-treated group. CONCLUSIONS Topical ketorolac is an effective inhibitor of miosis during phacoemulsification cataract surgery, and provides a more stable mydriatic effect throughout the surgical procedure.

Abstract
OBJECTIVE To evaluate the effectiveness of an ophthalmic nonsteroidal anti-inflammatory drug (NSAID) in the treatment of noninfected, non-contact lens-related, traumatic corneal abrasions and no pressure patch. DESIGN A single-center, randomized, double-masked, placebo-controlled study. PARTICIPANTS One hundred patients with noninfected, non-contact lens-related, traumatic or foreign body removal-related corneal abrasions less than 36 hours in duration. INTERVENTION All patients received a cycloplegic drop and erythromycin or polymyxin B (Polysporin Ophthalmic Ointment, Burroughs Wellcome, Research Triangle Park, NC). Patients were then randomized to receive either ketorolac tromethamine 0.5% ophthalmic solution or control vehicle drops. MAIN OUTCOME MEASURES The main outcome measures were six subjective symptoms monitored daily, evaluation of corneal abrasion, and determination of adverse events. Long-term complications were determined 3 to 8 months after randomization. RESULTS Twelve patients were excluded from the study. One day after randomization, patients receiving ketorolac tromethamine 0.5% ophthalmic solution noted significantly decreased levels of pain (P < 0.002), photophobia (P < 0.009), and foreign body sensation (P < 0.003) as compared with the control vehicle group. In addition, the time to resumption of normal activities was shorter in the group who received ketorolac tromethamine 0.5% ophthalmic solution (P < 0.001). There was no statistical difference in the amount of tearing, healing time, acuity changes, or complication rates between the two groups. CONCLUSIONS Ketorolac tromethamine 0.5% ophthalmic solution provides increased patient comfort without clinical adverse effects when used as adjunctive therapy in the treatment of noninfected, non-contact lens-related, traumatic corneal abrasions.

STUDY OBJECTIVES To examine the effect of timing of an intravenous (i.v.) dose (intraoperative vs. postoperative) of ketorolac tromethamine on pain scores and overall outcome after total abdominal hysterectomy (TAH) and myomectomy. DESIGN Prospective, randomized, placebo-controlled study. PATIENTS 248 ASA physical status I and II adult female patients scheduled for elective hysterectomy or myomectomy. INTERVENTIONS General anesthesia was administered that consisted of thiopental sodium for induction, enflurane or isoflurane in nitrous oxide-oxygen for maintenance, and small doses of fentanyl and midazolam. Patients were randomized into three groups to receive toradol/placebo on a dosing schedule of dose 1 given one-half hour prior to expected end of surgery, dose 2 given on awakening in the postanesthesia care unit, and doses 3, 4, and 5 given at 6, 12, and 18 hours, respectively, after dose 2; Group 1 patients received placebo (saline) for dose 1, ketorolac 60 mg i.v. for dose 2, and ketorolac 30 mg i.v. for doses 3, 4, and 5. Group 2 patients received ketorolac 60 mg i.v. for dose 1, placebo for dose 2, and ketorolac 30 mg i.v. for doses 3, 4, and 5. Group 3 patients received placebo for all doses. All patients were given i.v. morphine PCA postoperatively, and morphine usages, visual analog pain intensity (VAS) scores, as well as adverse events and median times to recovery milestones were recorded. MEASUREMENTS AND MAIN RESULTS VAS scores (mean) before dose 2 were significantly lower in Group 2 than Group 1, as were at-rest evaluations at 15 minutes and one hour. Group 2 patients also had decreased morphine requirements as compared to placebo. Both ketorolac groups (Groups 1 and 2) had significantly higher values for patient and observer overall ratings, case of nursing care, and tolerability as compared to placebo (Group 3). There were no significant differences among groups in adverse events or median times to recovery milestones. CONCLUSIONS Although it is possible to demonstrate an improvement in early postoperative pain scores with intraoperative ketorolac and better overall ratings of ketorolac both intraoperatively and postoperatively as compared with placebo, the lack of clinically significant differences in analgesic efficacy in the two active study groups indicates the need for a careful consideration by the clinician of the risks versus benefits involved in the administration of antiplatelet medication in the perioperative period.

Abstract
The efficacy of postoperative pain relief by ketanov and tramal was assessed in 42 patients operated on the abdominal organs and lower limb arteries. The time of development of the analgesic effect and duration and depth of analgesia were compared. The drug effects were compared from protocols of clinical examination, hemodynamic changes, and time course of external respiration and blood saturation with oxygen. The findings confirm a high analgesic effect of ketanov, which is not inferior to tramal, and by some parameters even higher.

Abstract
BACKGROUND A randomized, double-masked study was conducted to investigate the effects of 0.5% ketorolac tromethamine (Acular) and 0.1% diclofenac sodium (Voltaren) on normal human corneal sensation. METHODS Thirty normal volunteers were divided into two groups, (1) two-drop group, and (2) multiple-drop group. In the two-drop group, 15 volunteers randomly received two drops of 0.5% ketorolac tromethamine on one eye and two drops of 0.1% diclofenac sodium on the fellow eye. A masked investigator measured corneal sensation with the Cochet-Bonnet esthesiometer before applying the drops, and at 15, 30, and 60 minutes after using the eye drops. In the multiple-drop group, another 15 volunteers were randomly administered one drop of 0.5% ketorolac tromethamine or 0.1% diclofenac sodium in each eye, and the procedure was repeated every 5 minutes for 20 minutes. Corneal sensation was measured before, and 0, 15, 30 and 60 minutes after applying the drops. RESULTS In the two-drop group, neither of the eye drops had any effect on corneal sensation when only two drops were applied. In the multiple-drop group, corneal sensation was significantly reduced after multiple drops (p < 0.05) and was subsequently effective for at least 1 hour. CONCLUSION Both 0.5% ketorolac and 0.1% diclofenac can significantly decrease corneal sensation in normal eyes when multiple drops are used.

Abstract
Ketorolac tromethamine (KT) is a nonsteroidal, antiinflammatory analgesic. Its nonsedating property makes it an attractive analgesic for sleep apnea patients undergoing uvulopharyngopalatoplasty, but its antiplatelet activity makes the potential for postoperative hemorrhage a concern. A prospective, randomized, double-blind study was designed to evaluate the bleeding risk of KT using adult tonsillectomy patients as the model. Patients were randomized into two groups receiving Meperidine (MP) (controls) or KT for the first postoperative day. Posttonsillectomy bleeding rates of 7% (3/43) in the MP group and 18.9% (7/37) in the KT group were demonstrated, but this difference was not statistically significant. The number of KT doses administered had no effect on the incidence of bleeding or the number of cases requiring return to the operative suite for hemostasis. Although this study did not attain statistical significance, the trend towards increased hemorrhage with KT is worrisome. This study and other reports in the literature support the manufacturer's warning that the use of KT is contraindicated in major surgery.

Abstract
Pain was and in part still is a constant feature of surgical practice: before, during and after surgery. To start with painful symptoms represent a fundamental diagnostic element, given that in over 60% of cases pain is the primary indication for surgery. During the operation, pain used to constitute the main impediment to the surgeon's activities, until the introduction of ether and the birth of modern anesthesia. Lastly, the postoperative period is also painful so much so that whereas until fifty years ago patients were above all afraid of the operation, patients nowadays are concerned about the pain during the days after the operation. Moreover, over 50% of patients undergoing surgery are unsatisfied with the treatment of postoperative pain, in spite of the fact that drugs are available which enable us to control it. The authors studied the quality of postoperative analgesia in 357 patients, who received treatment with ketorolac tromethamine 30 mg i.v. on leaving the operating theatre, and subsequently i.m. every 8 hours starting from 3 hours after surgery. The use of ketorolac tromethanine demonstrated effective analgesia and was well accepted by patients, without revealing any particular collateral effects.
