Abstract
Ketoprofen (KTP) is an Active Pharmaceutical Ingredient (API) that has low solubility in aqueous solvents. The use of KTP salts has attracted attention due to its improvements in terms of solubility, tolerability, higher rate and extent of absorption, and faster onset of the therapeutic effect. In this work, a crystalline KTP sodium salt (coded as KTP-Na) was successfully obtained and widely characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), solubility and accelerated stability studies. XRD results showed that KTP-Na is not yet reported in the literature. Moreover, FTIR, DSC and TGA were useful for differentiation of KTP-Na from the KTP commercialized form (coded as KTP-R1). The solubility of KTP-Na in water was about 80 times greater than the KTP-R1. However, KTP-Na showed lower physical stability in storage conditions at 40 ± 2°C/ 75% ± 5% RH when compared to KTP-R1, which was shown to be related to a high hygroscopicity of KTP-Na. Therefore, due to its higher solubility, KTP-Na may be a viable alternative for use in solid dosage forms. However, the presence of moisture must be strictly controlled to avoid water absorption and consequent amorphization.

Abstract
Ketoprofen lysine salt (Artrosilene®, injectable solution) is a non-steroidal anti-inflammatory agent frequently administered by slow intravenous infusion with portable elastomeric infusion systems in association regimen with other analgesic drugs. The aim of this study was to investigate the physicochemical compatibility between ketoprofen lysine salt (Artrosilene®, injectable solution) and other injectable drugs frequently used in association, such as tramadol hydrochloride, keterolac tromethamine and morphine hydrochloride, into the Infusor LV5, Baxter elastomeric infusion system. Physicochemical properties of drug mixture, including colour, clarity, pH and drug content were observed or measured by a reversed-phase HPLC method with UV detection, before and after (up to 7 days) mixing at room temperature and under light protection. The results obtained demonstrated the physicochemical compatibility of ketoprofen lysine salt (Artrosilene®, injectable solution) with all drug formulations at every tested mixing ratios into Baxer Infusor LV5 infusion devices.

Abstract
Because many complex physiological processes are controlled by multiple biomolecules, comprehensive treatment of certain disease conditions may be more effectively achieved by administration of more than one type of drug. Thus, the objective of the present research was to develop a multilayered, polymer-based system for sequential delivery of multiple drugs. The polymers used were cellulose acetate phthalate (CAP) complexed with Pluronic F-127 (P). After evaluating morphology of the resulting CAPP system, in vitro release of small molecule drugs and a model protein was studied from both single and multilayered devices. Drug release from single-layered CAPP films followed zero-order kinetics related to surface erosion of the association polymer. Release studies from multilayered CAPP devices showed the possibility of achieving intermittent release of one type of drug as well as sequential release of more than one type of drug. Mathematical modeling accurately predicted the release profiles for both single layer and multilayered devices. The present CAPP association polymer-based multilayer devices can be used for localized, sequential delivery of multiple drugs for the possible treatment of complex disease conditions, and perhaps for tissue engineering applications, that require delivery of more than one type of biomolecule.

Abstract
OBJECTIVE: In our previous study, we reported that both uvulopalatopharyngoplasty (UPPP) and tonsillectomy are associated with unacceptable intense pain during the first 24 hours after surgery. To investigate the pain progression at home, we followed the same 53 patients for 14 days after surgery. Twenty-two patients underwent tonsillectomy and 31 patients underwent UPPP.
STUDY DESIGN: A prospective, longitudinal, parallel-group study was conducted.
METHODS: Beginning on the first postoperative day, the patients were allowed to use 50 mg ketoprofen capsules at a dosage of 5 mg/kg/24 hr. The patients evaluated their own pain four times a day for the first 5 days. Two weeks after the surgery during a follow-up visit patients reported the present pain; and a total consumption of analgesics, and all adverse events for 14 days.
RESULTS: Patients in both study groups had significant pain, especially in the morning, for the first week after surgery. In half of the patients, severe pain interfered with eating and sleeping, and in one third of the patients, the pain lasted 2 weeks or longer. The need for ketoprofen was significantly higher after UPPP than that after tonsillectomy ( P = 0.001). One patient after tonsillectomy and 3 patients after UPPP needed electrocautery to stop secondary bleeding.
CONCLUSIONS: Both UPPP and tonsillectomy are associated with intense postoperative pain. Standard ketoprofen capsules are too short-acting to ensure undisturbed sleep.

Abstract
OBJECTIVE To determine whether postoperative administration of ketoprofen or carprofen had any effects on short- or long-term results of femoral head and neck excision (FHNE) in dogs. DESIGN Prospective randomized controlled trial. ANIMALS 40 client-owned, large-breed dogs undergoing FHNE and 15 healthy large-breed dogs used as controls for hip joint angle measurements and force plate analyses. PROCEDURE Dogs undergoing FHNE were treated with ketoprofen, carprofen, or a placebo for 21 days after surgery. Hip joint abduction and extension angles were measured at the end of surgery and 120 days later. Lameness scores were assigned, and force plate analyses were performed on days 3, 15, and 120. RESULTS There were no significant differences among treatment groups in regard to hip joint angles or lameness scores. Force plate analysis revealed that dogs in all 3 treatment groups bore consistently less weight on the operated limb than did control dogs for the duration of the study. Dogs receiving ketoprofen had greater peak propulsive force at a walk on day 3 and greater peak vertical force at a walk on day 15 than did dogs receiving the placebo. Treatment of an acute condition and preservation of the lesser trochanter, but not postoperative analgesic administration, were positively associated with ground reaction forces on day 120. Owners of 12 of 31 dogs indicated that the dog's gait worsened for a few days after discontinuation of analgesic administration. CONCLUSIONS AND CLINICAL RELEVANCE Administration of ketoprofen or carprofen after surgery was not associated with long-term results of FHNE, probably because of the impact of other factors. Because some owners noticed worsening of the lameness following cessation of analgesic administration in the present study, it is possible that longer administration would have improved long-term results.

Abstract
Ketoprofen lysine salt (Artrosilene) Fiale) is a non-steroidal anti-inflammatory agent frequently administered by intravenous infusion in association regimen with other drugs, such as steroidal anti-inflammatory, anti-hemorrhagic, anti-spastic, anti-ulcer, and antibacterial drugs. The aim of this study was to investigate the physicochemical compatibility between ketoprofen lysine salt (Artrosilene) Fiale) and other injectable drugs frequently used in association. Physicochemical properties of ketoprofen lysine salt mixtures with different drugs, including colour, clarity, pH and drug content were observed or measured before and after (up to 5 h) mixing at room temperature and under light protection. Results show that the association of Artrosilene Fiale with different drugs does not cause, up to 5 h from mixing, any significant variation in the physicochemical parameters mentioned above. In conclusion, the results obtained demonstrated the physicochemical compatibility of ketoprofen lysine salt (Artrosilene) Fiale) with several drugs.

Abstract
BACKGROUND Different parenteral routes of administration of NSAIDs such as ketoprofen have not been properly compared in children. This study was designed to compare the analgesic efficacy of intravenous and intramuscular ketoprofen for pain management in children after day-case adenoidectomy. METHODS A total of 120 children, aged 1-9 years, who were scheduled to undergo adenoidectomy, were randomized to receive ketoprofen 2 mg/kg either intravenously with intramuscular placebo (n = 40) or ketoprofen 2 mg/kg intramuscularly with intravenous placebo (n = 40), or both intravenous and intramuscular placebo (n = 40) at induction of anesthesia. The study design was prospective and double-blind with parallel groups. Pain was assessed at rest and during swallowing using the Maunuksela pain scale during 3 h after surgery, and fentanyl i.v. was given for rescue analgesia. RESULTS Children in the Placebo group needed significantly more doses of fentanyl (72 doses) than either children in the intravenous group (47 doses) or children in the intramuscular group (51 doses) (P = 0.021). In addition, a higher proportion of children in the Placebo group than in the two ketoprofen groups (P = 0.03) demanded rescue analgesic. No difference in the need for rescue analgesia or in pain scores was found between the two ketoprofen groups. Children in the intravenous group had less pain than children in the Placebo group. The difference was significant during swallowing at 1 h after surgery (P = 0.046) and for the worst pain observed during swallowing for 3 h after surgery (P = 0.022). There were no differences between the three groups with respect to operation times, amount of perioperative bleeding, or rate or extent of adverse events. CONCLUSION The efficacy of intravenous and intramuscular ketoprofen was similar, and they both differed from placebo.

Abstract
Because nonsteroidal anti-inflammatory drugs, such as ketoprofen, prolong bleeding time, their preoperative administration may both prolong operation time and delay discharge. Therefore, charts of 335 children who had undergone adenoidectomy were evaluated to determine the effect of ketoprofen on operation time (OPERTIME) and length of hospital stay (ACTUAL LOS). The study was conducted in three phases (I-III) which differed from each other in the dose of i.v. ketoprofen, 0.3-3 mg x kg(-1). All phases were conducted with parallel groups using a prospective, randomized, and double blind design; moreover, phases I and III were placebo-controlled. OPERTIMEs were similar between Placebo groups and Ketoprofen groups. The dose of ketoprofen did not affect OPERTIME or ACTUAL LOS. In phase I, ACTUAL LOS was significantly longer in the Placebo group (251 +/- 46 min, mean +/- SD) compared to the Ketoprofen group (225 +/- 44 min, P=0.006). In conclusion, preincisional ketoprofen did not prolong OPERTIME or delay discharge in children undergoing adenoidectomy.

Abstract
Therapies in current use for episodic tension-type headache (ETTH) are often unsatisfactory. Few trials have been conducted to demonstrate efficacy of any of them. This multicenter placebo-controlled randomized parallel-groups study compared the analgesic efficacy of single oral doses of ketoprofen 25 mg and acetaminophen 1000 mg as outpatient treatment of 1 attack of ETTH. Efficacy was assessed by patients as pain relief on a diary-entered 7-point categorical scale. A total of 457 patients treated 348 attacks, 330 of which were evaluable. There were no serious adverse events (AEs); gastrointestinal AEs were most common on all treatments. Total relief from pain after 2 h was recorded by 16% of patients on placebo, 28% on ketoprofen, and 22% on acetaminophen. Worthwhile effect or total relief (all other responses were regarded as treatment failures) were recorded by 36% on placebo, 70% on ketoprofen (p < 0.001), 61% on acetaminophen (p < 0.001). The difference between ketoprofen and acetaminophen was not significant (p = 0.24). Various secondary efficacy measures confirmed superiority of both active treatments over placebo, with some trends for slightly better outcome on ketoprofen that on acetaminophen. This study demonstrates that ketoprofen is an effective alternative to standard therapy in ETTH.

Abstract
Ketoprofen creams were evaluated for the treatment of periodontal disease in a placebo-controlled, double-blind study in the rhesus monkeys, Macaca mulatta. Two formulations containing ketoprofen (1%), with or without vitamin E, were evaluated against appropriate controls (8 monkeys per group). Two weeks prior to treatment, the animals received prophylaxis on only the left side of the mouth (spontaneous model). Selected teeth on the right side of the mouth were ligated (ligature model). The creams were administered to the gingiva once daily at a standard dose of 1.8 ml per monkey for 6 months. Clinical assessments were made 2 wk before initiation, at baseline and 1, 2, 3 and 6 months post-treatment. The clinical parameters included plaque formation, gingival redness, edema, bleeding on probing and Ramfjord Attachment Level measurements (RAL). Radiographs were taken at 2 wk before initiation, baseline and at 3 and 6 months post-treatment. Digital, subtraction radiography was used to measure vertical linear bone loss along the interproximal root surfaces of the left and right mandibular first molars. Gingival crevicular fluid (GCF) was collected for biochemical assays on PGE2, TxB2, LTB4, IL-1 beta and TNF alpha. There were no significant differences among groups with respect to gingival indices. Radiographic data demonstrated significant positive effects on bone activity in both groups treated with ketoprofen formulations with improvement over time in the ligature model (0.01 < or = p < or = 0.04). The placebo group exhibited bone loss of 1.96 +/- 0.48 and 1.40 +/- 0.56 mm per site at 3 and 6 months, respectively. The group treated with ketoprofen cream showed an apparent bone gain of 0.28 +/- 0.41 and 0.78 +/- 0.47 mm per site at 3 and 6 months, respectively. The group treated with ketoprofen cream containing vitamin E showed a mean bone loss of 0.41-0.48 mm per site at 3 months with improvement to an apparent bone gain of 0.31 +/- 0.44 mm per site at 6 months. The biochemical data demonstrated early and significant suppression of GCF-LTB4 by both ketoprofen formulations at 1 month, which preceded the significant suppression of GCF-PGE2 at 2 and 3 months in the ligature model (p < 0.003) and at 2 to 6 months in the spontaneous model (p < 0.02). We conclude that ketoprofen at 1% level in suitable topical vehicles can effectively inhibit GCF-LTB4 and GCF-PGE2 and positively alter alveolar bone activity in the ligature-induced model of periodontitis in the monkey.

Abstract
This study assesses the anti-inflammatory/analgesic effects of ketoprofen a non-steroidal anti-inflammatory drug, using the method of c-Fos immunoreactivity at the spinal cord level in two models of noxious stimulation: carrageenan-induced inflammatory pain or acute noxious heat. Ketoprofen was pre-administered intravenously or orally 25 min before an intraplantar injection of carrageenan (6 mg in 150 microliters of saline) in hindpaw of the non-anaesthetised rat or before a single noxious heat (52 degrees C, 15 sec) stimulation of hindpaw of the anaesthetised rat. Three hours after carrageenan or 2 h after noxious heat, the number of spinal c-Fos protein-like immunoreactive (c-Fos-LI) neurons in L4-L5 segments and both the ankle and paw diameter, the indicator of peripheral oedema, were assessed. Pre-administered ketoprofen (1, 3 and 10 mg/kg i.v.) dose-dependently blocks the development of the carrageenan-induced spinal c-Fos protein expression and peripheral oedema, with the highest dose influencing in parallel both parameters (75 +/- 2% diminution of total number of c-Fos-LI neurons per L4-L5 section; 64 +/- 4% and 82 +/- 6% diminution of paw and ankle oedema, respectively). The effect of ketoprofen was significantly greater on the number of c-Fos-LI neurons in deep, as compared to superficial, laminae. Furthermore, the dose-dependent effects of ketoprofen on the carrageenan-induced spinal c-Fos protein expression and both the paw and ankle oedema were correlated. Oral pre-administration of ketoprofen (20 mg/kg) produced the blockage of development of the carrageenan-induced spinal c-Fos protein expression (65 +/- 3% diminution of total number of c-Fos-LI neurons per L4-L5 section) and peripheral oedema (20 +/- 3% and 59 +/- 10% diminution of paw and ankle oedema, respectively). In contrast, the same doses of both the intravenous and oral pre-administration of ketoprofen did not influence either the spinal c-Fos protein expression nor slightly enhanced paw diameter induced by a single noxious heat stimulation. This study suggests a predominant peripheral site, without excluding a central site of action of ketoprofen in the carrageenan-induced inflammation. The method of c-Fos protein-like immunoreactivity revealed ketoprofen to be more potent in comparison to members of other families of non-steroidal anti-inflammatory drugs, previously studied in the same experimental conditions of carrageenan-induced inflammatory pain.

Abstract
1. Flufenamic and tolfenamic acids have recently been shown to inhibit receptor-mediated calcium influx in human neutrophils. The present work was designed to study the effects of these two nonsteroidal anti-inflammatory drugs on human peripheral blood lymphocyte activation. 2. Peripheral blood mononuclear cells (PBMNCs; containing 90% lymphocytes) were stimulated by mitogen concanavalin A (Con A) or by a combination of an inhibitor of microsomal Ca(2+)-adenosine triphosphatase thapsigargin (TG) and phorbol myristate acetate (PMA). The effects of the two fenamates on cell proliferation were compared with respective changes in calcium metabolism. 3. Flufenamic and tolfenamic acids (10-100 microM) inhibited both Con A and TG + PMA-induced [3H]-thymidine incorporation in a dose-dependent manner. At the same concentration range, the two fenamates inhibited the increase in intracellular free calcium concentration induced by Con A or TG + PMA. This effect was due to inhibition of calcium influx whereas calcium release from intracellular stores remained unaltered. 4. The inhibition of divalent cation influx was confirmed by showing that fenamates inhibited TG + PMA-induced Mn2+ influx. 5. The inhibitory effects of fenamates on PBMNC proliferation and Ca2+ influx were qualitatively similar with those of SK&F 96365, an earlier known inhibitor of receptor-mediated calcium entry. Ketoprofen, a chemically different prostaglandin synthetase inhibitor did not show similar suppressive effects on PBMNCs. 6. The data suggest that flufenamic and tolfenamic acids suppress proliferation of human peripheral blood lymphocytes by a mechanism which involves inhibition of Ca2+ influx and is not related to inhibition of prostanoid synthesis.

Abstract
We investigated the capacity of ketoprofen lysine salt (KLS) to counteract the pulmonary effects of some mediators of airway inflammation. The protective effect of KLS and its R-isomer against bradykinin (BK) induced plasma extravasation in the airways and bronchoconstriction was evaluated in anaesthetized guinea-pigs, in parallel with the capacity of KLS to inhibit the production of thromboxane A2 (TXA2). Moreover, we studied the ability of KLS to modulate leukotriene C4 (LTC4) and acetylcholine (ACH) induced bronchoconstriction and the associated production of TXA2. Nimesulide (NIM) was used as the reference compound. KLS dose-dependently inhibited the bronchoconstriction and the associated production of TXA2 induced by BK, with closely related ID50 values of 31.2 and 34.0 micrograms/kg i.v., respectively. The protection was evident 10 min after KLS administration and, at 100 micrograms/kg i.v., lasted up to 2h, Moreover, KLS dose-dependently inhibited the increase in capillary permeability induced by BK, with a potency (ID50 23.4 micrograms/kg i.v.) slightly higher than that shown against the bronchoconstriction. KLS also prevented the bronchoconstriction and TXA2 production triggered by LTC4, but not ACH induced bronchoconstriction. In all the models studied, KLS was about 10 times more potent than NIM. These data demonstrate the capacity of KLS to counteract the bronchoconstriction induced by BK and LTC4 and to a large extent the airway inflammation induced by BK. Blockade of prostanoid production is likely to account for this protective effect, since the R-isomer of KLS was devoid of significant activity.

Abstract
The aim of the study was to assess the efficacy and tolerability of a single oral dose of ketoprofen 25 mg in comparison with single doses of ketoprofen 2 x 25 mg, paracetamol 500 mg and 1,000 mg, and placebo in the treatment of episodic tension-type headache. The study was conducted as a single centre, double-blind, randomized, placebo-controlled, five-period, within-patient comparative trial in outpatients with episodic tension-type headache according to the International Headache Society's diagnostic criteria. Each patient had to treat five attacks of episodic tension-type headache with a single dose of each of the tested medications with a minimum interval of 72 h between two attacks. Details of the attack and response to treatment were recorded on a diary card. Altogether 30 patients treated 5 attacks and 2, 3, 1 and 4 patients treated 4, 3, 2 and 1 attack, respectively. The primary variable was decrease in headache pain intensity from baseline to 2 h after intake, evaluated by means of a 100 mm visual analogue scale. Ketoprofen 50 mg was significantly better than placebo and paracetamol for this main criterion. Neither of the paracetamol groups differed from the placebo group. Only a few adverse events were reported, usually of mild or moderate severity, with no difference between the treatments. Ketoprofen 50 mg may be considered an effective and well tolerated analgesic in the treatment of episodic tension-type headache of moderate or severe intensity.

Abstract
Pharmacokinetic studies are reported after single oral administration of 3 mg/kg of stereochemically pure (S)-ketoprofen [(S)-KP] and (R)-ketoprofen [(R)-KP] to three male Cynomolgus monkeys and after repeated administration for 6 months of 3, 15 and 75 mg/kg/day of (S)-KP to both male and female monkeys. A high-performance liquid chromatographic (HPLC) analysis was performed without derivatization of the samples, using a chiral column. The pharmacokinetic parameters for (S)-KP after administration of (S)-KP and for (R)-KP after administration of (R)-KP were, respectively, elimination half-life 2.32 +/- 0.36 and 1.64 +/- 0.40 h; oral clearance 3.50 +/- 0.66 and 7.50 +/- 3.20 ml/min/kg; apparent volume of distribution 0.74 +/- 0.24 and 1.16 +/- 0.76 liter/kg; mean residence time 1.79 +/- 0.77 and 1.41 +/- 0.65 h; area under the concentration/time curve 14.16 +/- 2.93 and 7.31 +/- 2.98 micrograms.h/ml. Forty-nine percent unidirectional bioinversion of (R)-KP to (S)-KP was observed in this species and the pharmacokinetic parameters for the (S)-KP resulting from this inversion were also calculated. In the study of 6-month repeated administration of (S)-KP, linear pharmacokinetic behavior and no evidence of drug accumulation were observed at the three dose levels.

Abstract
The pharmacological activity of rac-ketoprofen and its enantiomers was investigated in vitro using different cellular models. The effect of these compounds on arachidonic acid metabolism was assessed by measuring the inhibition of prostanoid generation under the action of several agonists. Thus, we have evaluated the inhibition of (1) thromboxane B2 synthesis in rabbit platelets and human polymorphonuclear leukocytes (PMNs), (2) prostaglandin E2 synthesis in three cultured cells, namely human umbilical vein endothelial cells (HUVEC), human keratinocytes, and mouse macrophage-like P388D1 cells. The IC50 values found for (+)-(S)-ketoprofen were in the range between 0.1 nM and 0.8 microM, being slightly lower in all models than those found for rac-ketoprofen (0.4 nM-3 microM). On the other hand (-)-(R)-ketoprofen showed inhibition of cyclooxygenase only at concentrations two or three orders of magnitude higher than those required for the (+)-(S) enantiomer. These results, obtained with cell types of relevance for inflammatory processes and with compounds of high optical purity, demonstrate that the prostanoid biosynthesis inhibition caused by the drug rac-ketoprofen is exclusively due to its dextrorotatory enantiomer.
