RESUMO

BACKGROUND: Multimodal analgesia for total hip arthroplasty (THA) is increasingly employed to reduce early postoperative pain and promote fast patient discharge. The aim of this study was to compare the efficacy and tolerability of tramadol/dexketoprofen (TRAM/DKP, Group A) versus paracetamol + tramadol (PARA+TRAM, Group B) in patients undergoing THA using minimally invasive direct anterior approach (DAA). METHODS: A single-centre, randomised, single-blind, parallel, interventional study conducted in 323 patients undergoing primary THA with DAA was performed. Group A consisted of 188 patients and Group B of 135. The primary endpoints were the change from baseline (measured 2 hours postoperatively) in pain intensity (PI) during the treatment period (48 hours), assessed by visual analogue scale (VAS) at pre-specified postoperative time-points (2, 8, 24, 48 hours) and the total rescue medication (RM) use during the first 24 hours postoperatively. RESULTS: As early as 2 hours after baseline, Group A showed a greater PI reduction from baseline compared to Group B (-26.24% vs. -6.87%; p < 0.001). A lower mean PI (VAS) score was consistently found over the entire observation period following treatment with TRAM/DKP than with PARA+TRAM as well as more than 2-fold higher proportion of responders at the end of treatment period. More patients in Group B required RM in comparison to those in Group A (15.6% vs. 3.7%, p < 0.001). Both treatments were well tolerated. CONCLUSIONS: After THA, oral TRAM/DKP provides faster and greater pain relief when compared to intravenous PARA+TRAM with limited consumption of RM and favourable tolerability profile. Our study expands the use of TRAM/DKP in the setting of major orthopaedic surgeries. CLINICAL TRIAL REGISTRATION: clinicaltrials.gov (NCT04178109).

RESUMO

PURPOSE: Although different forms of lidocaine are used for migraine attack headaches, the effect of intravenous lidocaine is still limited. This study aimed to investigate the effects of intravenous lidocaine infusion for the treatment of migraine attack headaches. METHODS: A hundred patients with migraine attacks, aged between 18 and 65, were randomly divided into two groups. The lidocaine group (n = 50) received a 1.5 mg/kg lidocaine bolus and a 1 mg/kg infusion (first 30 min), followed by a 0.5 mg/kg infusion for a further 30 min intravenously. The non-steroidal anti-inflammatory drug (NSAID) group (n = 50) received 50 mg dexketoprofen trometamol and saline at the same volume as the lidocaine at the same time intervals intravenously. The Visual Analog Scale (VAS) pain scores, additional analgesia requirement, side effects, and revisits to the emergency department were recorded. RESULTS: The VAS score was significantly lower in the lidocaine group than in the NSAID group for the first 20th and 30th minutes (p = 0.014 and p = 0.024, respectively). There was no difference between the VAS scores for the remaining evaluation times (p > 0.05). In terms of secondary outcomes, rescue medication requirement was not different between the two groups at both the 60th and 90th minutes (p > 0.05). However, the number of patients revisiting ED within 48-72 h was statistically less in the lidocaine group than in the NSAID group (1/50 vs. 8/50; p = 0.031). CONCLUSION: Intravenous lidocaine may be an alternative treatment method for patients with migraine attack headaches in the emergency department.

RESUMO

The purpose of this study was to evaluate the antinociceptive interaction between dexketoprofen and tapentadol in three different dose ratios, as well as the ulcerogenic activity of this combination. Dose-response curves were carried out for dexketoprofen, tapentadol, and dexketoprofen-tapentadol combinations in the acetic acid-induced writhing test in mice. On the other hand, the gastric damage of all treatments was assessed after the surgical extraction of the stomachs. Intraperitoneal administration of dexketoprofen and tapentadol induced a dose-dependent antinociceptive effect, reaching a maximal effect of about 58% and 99%, respectively. Isobolographic analysis and the interaction index showed that the three proportions produced an analgesic potentiation (synergistic interaction). Interestingly, the 1:1 and 1:3 ratios of the drugs combination produced minor gastric injury in comparison with the 3:1 proportion. Our data suggest that all proportions of the dexketoprofen-tapentadol combination produced a synergistic interaction in the acetic acid-induced visceral pain model in mice with a low incidence of gastric injury.

RESUMO

BACKGROUND: We tested if disrupting iron utilisation by P. aeruginosa by adding the Tris-buffered chelating agent CaEDTA to nebulised tobramycin would enhance bacterial clearance and improve lung function in CF patients. METHODS: In this double-blind, randomised controlled trial, 26 episodes (25 patients) with P. aeruginosa infection admitted to two CF centres for treatment of an acute pulmonary exacerbation were randomly assigned to receive either 75 mg CaEDTA in Tris-buffered saline or placebo (Tris-buffered saline) nebulised in combination with 250 mg tobramycin twice daily for six weeks followed with four week safety follow-up. Primary endpoints were safety, tolerability, and bacterial density of P. aeruginosa. A secondary endpoint was lung function. RESULTS: The study drug was well tolerated with adverse events comparable in both groups. The mean (SD) reduction in sputum P. aeruginosa count (log10 CFU/g) in the CaEDTA vs placebo group was 2·05 (2·57) vs 0·82 (2·71) at two weeks relative to admission (p = 0·39). The mean improvement in ppFEV1 was 16 vs 5 (p = 0·16); 11 vs 2 (p = 0·28); and 6 vs 2 percentage points (p = 0·47) at two, six, and ten weeks in CaEDTA and placebo groups, respectively. CONCLUSIONS: In this pilot study in CF patients, an increase in the reduction of sputum density of P. aeruginosa and an increase in ppFEV1 was observed in the group of patients who received Tris-CaEDTA added to inhaled tobramycin compared to the group who received inhaled tobramycin alone, although these differences were not statistically significant. The treatment was also shown to be safe.

RESUMO

BACKGROUND: Felbinac trometamol, an anti-inflammatory and analgesic drug, has been used to treat immediate postoperative pain. OBJECTIVE: The aim of this study was to evaluate the safety, tolerability, and pharmacokinetics of single or multiple intravenous infusions of felbinac trometamol in healthy Chinese volunteers. METHODS: A total of 56 healthy subjects were enrolled in a single-ascending dose study (11.78-377.00 mg), meanwhile 36 subjects were enrolled in a multiple-ascending dose study (47.13-188.50 mg). Safety endpoints included treatment-emergent adverse events, vital signs, electrocardiograms, and laboratory parameters. Pharmacokinetic endpoints included exposure of subjects to felblinac and metabolites of the drug in plasma, urine, and feces. RESULTS: Felblinac time to maximum plasma concentration was obtained at 0.5 h, corresponding to the end of the infusion. Maximum plasma concentration and area under the curve increased in a dose-dependent manner for felblinac and its metabolite, showing linear pharmacokinetic characteristics at single and multiple doses. After intravenous infusions of multiple doses three times (30 min each time) per day, the accumulation ratio of felblinac and its metabolite based on the area under the curve had a range of 1.34-1.45 and 1.60-1.87, respectively, across cohorts. After administration of the fourth dose, the plasma concentration of both felblinac and its metabolites was maintained at a steady state. Felbinac trometamol was well tolerated. Neither treatment-emergent adverse event frequency nor severity increased with increasing felbinac trometamol dose. CONCLUSIONS: Felbinac trometamol was well tolerated in our study. Based on the dose range in this study, 94.25 mg is the recommended target dose for a phase II study. CLINICAL TRIAL REGISTRATION: CTR20170496 and CTR20180896. The dates of registration are 2017-06-19 and 2018-07-02 ( https://www.chinadrugtrials.org.cn/ ).

RESUMO

STUDY OBJECTIVE: The objective of this study was to determine the analgesic efficacy and safety of intravenous, single-dose metoclopramide versus dexketoprofen trometamol versus metoclopramide+ dexketoprofen trometamol in patients presenting with acute migraine attack to the emergency department (ED). METHODS: This single-center, randomized, double-blind study was conducted in a tertiary care ED. Eligible patients met the migraine criteria of the International Headache Society were randomized to receive 10 mg intravenous metoclopramide, 50 mg intravenous dexketoprofen trometamol, or 50 mg dexketoprofen trometamol +10 mg metoclopramide. Visual analogue scale (VAS) was used for pain measurement at baseline, after 15 and 30 min. The primary outcome measure was the changes in the VAS scores at the 15th and 30th minutes of treatment. The secondary outcome measures were the presence of adverse effects and the requirement of rescue medicine. RESULTS: Patients (n = 150) were randomized into 3 groups with similar VAS scores at baseline. While there was no significant difference between metoclopramide and dexketoprofen trometamol in reducing pain at the 15th and 30th minute (p = 0.618 and p = 0.862, respectively) and between metoclopramide and metoclopramide + dexketoprofen trometamol at the 15th minute (p = 0.074), metoclopramide + dexketoprofen trometamol was superior to both metoclopramide [mean difference: -13.2 mm (95% CI -23.1 to -3.3)] and dexketoprofen trometamol [mean difference: -11.02 mm (95% CI -20.9 to -1.1)] at the 30th min (p = 0.006 and p = 0.025 respectively). The rescue drug was required by 3 patients (6%) were in metoclopramide group, 4 patients (8%) in dexketoprofen trometamol group and one patient (2%) in the metoclopramide + dexketoprofen trometamol group. No side effects were observed in subjects in three treatment groups. CONCLUSION: No significant difference in VAS was found between three treatment groups at the 15th minute, but metoclopramide + dexketoprofen trometamol was superior to both metoclopramide and dexketoprofen trometamol at the 30th min.

RESUMO

AIM: The present study aims to evaluate protective effects of a novel histidine-tryptophan-ketoglutarate solution (HTK-N) and to investigate positive impacts of an additional luminal preservation route in cold storage-induced injury on rat small bowels. METHODS: Male Lewis rats were utilized as donors of small bowel grafts. Vascular or vascular plus luminal preservation were conducted with HTK or HTK-N and grafts were stored at 4°C for 8 h followed by ex vivo warm oxygenated reperfusion with Krebs-Henseleit buffer for 30 min. Afterwards, intestinal tissue and portal vein effluent samples were collected for evaluation of morphological alterations, mucosal permeability and graft vitality. RESULTS: The novel HTK-N decreased ultrastructural alterations but otherwise presented limited effect on protecting small bowel from ischemia-reperfusion injury in vascular route. However, the additional luminal preservation led to positive impacts on the integrity of intestinal mucosa and vitality of goblet cells. In addition, vascular plus luminal preservation route with HTK significantly protected the intestinal tissue from edema. CONCLUSION: HTK-N protected the intestinal mucosal structure and graft vitality as a luminal preservation solution. Additional luminal preservation route in cold storage was shown to be promising.

RESUMO

Non-steroidal anti-inflammatory drugs are drugs with analgesic, antipyretic, and anti-inflammatory effects. This study uses in vitro methods to investigate the potential and unknown genotoxic effects of dexketoprofen trometamol, an active substance in painkillers, on healthy human lymphocytes. In this study, a cytokinesis-block micronucleus cytome assay is used to investigate potential clastogenic, aneugenic activity and to identify chromosome breakages caused by the active drug substance dexketoprofen trometamol; a comet assay is performed to identify the genotoxic damage resulting from DNA single-strand breaks; a real-time reverse transcription polymerase chain reaction panel system is used to evaluate the potential negative effects on the expression of the genes responsible for DNA damage assessment. Dexketoprofen trometamol induces toxic effects in healthy human lymphocytes at concentrations of 750-1000 µg/mL and above, and shows clastogenic, aneugenic activity by inducing micronucleus formations at exposures of 750-500 µg/mL. At concentration intervals of 1000, 500, 250, 100 µg/mL, dexketoprofen trometamol also resulted in DNA damage in the form of strand breaks, as demonstrated by highly significant increases in DNA tail length and density comet parameters when compared to spontaneous values. Human lymphocytes exposed to 750-100 µg/mL dexketoprofen trometamol were found to have significantly increased levels of expression of the XPC, XRCC6, PNKP genes in the DNA damage signaling pathway. It can be concluded that dexketoprofen trometamol may have cytotoxic, cytostatic, genotoxic effects on healthy human lymphocytes in vitro, depending on the concentration and duration of exposure. It is anticipated that this outcome will be supported by advanced studies.

RESUMO

BACKGROUND: Acne is one of the most common skin problems among human populations. A facial cleanser formulated with alkyl ether carboxylate (AEC) and alkyl carboxylate (AC) can improve acne by cleansing sebum on facial skin but cannot effectively remove keratotic plugs in the skin pores. Recently, we confirmed that Tris (hydroxymethyl) aminomethane and L-arginine (Tris/Arg) is able to reduce sebum levels, disrupt keratotic plugs in vitro and decrease pore size on facial skin. OBJECTIVE: To compare the efficacy of the Tris/Arg-formulated cleanser with the AEC/AC cleanser in Thai subjects with acne. METHODS: We designed a randomized, double-blind, controlled, parallel trial. Thirty-four male Thai subjects with mild to moderate acne were assigned to one of two groups: one group used the Tris/Arg cleanser while the other used the AEC/AC-based cleanser twice a day for 4 weeks. RESULTS: After 4 weeks, significant decreases in noninflammatory acne were observed in both groups, yet significant decreases in inflammatory acne were only observed in the Tris/Arg cleanser group. The sebum level prior to and 30 minutes after facial washing showed no change in either group. The average pore size with keratotic plugs on the cheeks was significantly decreased in the Tris/Arg group. More than half of subjects in both groups observed acne improvement but more subjects in the Tris/Arg group noted pore size improvement. CONCLUSION: The Tris/Arg formulated cleanser has a high efficacy for significantly reducing both noninflammatory and inflammatory acne accompanied by decreases in pore size with keratotic plugs in male Thai subjects.

RESUMO

BACKGROUND: The efficacy of dexketoprofen for migraine attack remains controversial. We conduct a systematic review and meta-analysis to explore the influence of dexketoprofen supplementation versus placebo on pain control in migraine attack patients. METHODS: We search PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through March 2019 for randomized controlled trials (RCTs) assessing the effect of dexketoprofen supplementation versus placebo on pain control for migraine attack patients. This meta-analysis is performed using the random-effect model. RESULTS: Five RCTs involving 794 patients are included in the meta-analysis. Overall, compared with control group for migraine attack, dexketoprofen supplementation is associated with substantially increased pain free at 2 hours (RR = 1.90; 95% CI = 1.43-2.53; P < .0001), pain free at 48 hours (RR = 1.63; 95% CI = 1.07-2.49; P = .02), good or excellent treatment (RR = 1.48; 95% CI = 1.24-1.78; P < .0001) and pain relief at 2 hours (RR = 1.80; 95% CI = 1.17-2.77; P = .007), as well as reduced need for rescue drug (RR = 0.64; 95% CI = 0.43-0.94; P = .02), with no significant increase in adverse events (RR = 1.51; 95% CI = 0.87-2.62; P = .14). CONCLUSION: Dexketoprofen supplementation benefits to improve pain control at 48 hours and reduce the need for rescue drug in migraine attack patients.

RESUMO

Development of extended release oral formulations of dexketoprofen trometamol (DT), a rapidly eliminated drug with high solubility, poses a great challenge especially when a portion of the dose is to be absorbed from the colon. In this study, site-specific release-retardant mini-matrix tablets (SSRRMTs) were developed and functionally coated with pH-responsive materials to achieve a site-specific delivery of DT at the duodenojejunal (DSRRMT) and ileocecal (ISRRMT) regions. Stomach-specific coated mini-tablets (SSCMTs) were manufactured for immediate release of about 16% of the daily dose of DT in the stomach. The SSCMT, DSRRMT, and ISRRMT were combined into a solid dosage form (C-SSRRMT tablets or capsules) to achieve the required linear release profile for once daily administration of DT. The SSRRMT and C-SSRRMT formulations were evaluated for the physical properties, in vitro-disintegration and in vitro dissolution and proved to be consistent with the pharmacopeial specifications. The in vitro release profiles of both C-SSRRMT tablets and capsules showed a constant release rate of about 6 mg/h and were similar to that of the theoretical target linear release profile. The pharmacokinetic study using human volunteers showed the bioequivalence of a single oral dose of C-SSRRMT capsules compared to three-successive oral doses of the immediate release market tablets with less ups and downs in the drug levels. The C-SSRRMT capsules formulation, may therefore, constitute an advance in the extended oral delivery of DT without the lack of efficacy and the adverse events frequently encountered in multiple daily dosing of the immediate release tablets.

RESUMO

OBJECTIVE: To evaluate the efficacy of dexketoprofene trometamol solution following the administration of contrast agent for Endoscopic Retrograde Cholangiopancreatography (ERCP) in decreasing the rate of pancreatitis, in experimental rat model. STUDY DESIGN: Experimental study. PLACE AND DURATION OF STUDY: Faculty of Medicine, Research and Animal Laboratory of Bezmialem University, Istanbul, Turkey in January 2018. METHODOLOGY: Forty Wistar-Albino® male rats of 250-300g were divided into 4 equal groups. Group I underwent cannulation; group II had cannulation with saline; group III had cannulation and contrast agent; group IV had cannulation with contrast agent and dexketoprofene trometamol intra-muscular (IM). Twenty four hours following the procedure, the rats were sacrified and pancreatic tissues were examined histopathologically, with evaluation of blood levels of leukocyte, glucose, SGOT, LDH, amylase, and C-reactive protein (CRP) level. Histopathological grading of acute pancreatitis was performed using haematoxylin and eosin staining. RESULTS: Mean levels of amylase and leukocyte were found to be significantly higher in groups II, III, IV when compared to group I (p=0.001). CRP level was found to be highest in group III (p=0.001). Histopathological grade of pancreatitis was found to be significantly higher in groups II, III, IV than group I (p: 0.001, 0.001, 0.028, and 0.001, respectively). Scores of edema, acinar necrosis, inflammation and perivascular infiltration of group III were higher than in group IV (p=0.001). CONCLUSION: Intra-muscular administration of dexketoprofen trometamol during ERCP procedure may be beneficial in decreasing the rate of post-ERCP pancreatitis, as shown by histopathological and laboratory profile.

RESUMO

The main challenges in treating cancer using chemotherapeutics are insufficient dose at the target site and the development of drug resistance, while higher doses can induce side effects by damaging nontarget tissues. Combinatorial drug therapy may overcome these limitations by permitting lower doses and more specific targeting, thereby mitigating drug resistance and nontarget side effects. Recent reports indicate that nonsteroidal anti-inflammatory drugs (NSAIDs) have anticancer potential and can be used together with conventional chemotherapeutics to improve efficacy and safety. In the present study, imatinib mesylate and dexketoprofen trometamol were selected as model drugs to develop targeted surface-modified liposome and nanocochleate formulations for fibrosarcoma treatment. The physicochemical properties and in vitro efficacy of various formulations were evaluated by measurement of particle size distribution, polydispersity index, zeta potential, encapsulation efficiency, diffusion through Caco-2 cells, and toxicity in culture. Selected formulations were then evaluated in fibrosarcoma-bearing model mice by histopathological observations and tyrosine kinase receptor inhibition assays. The most effective formulation on the fibrosarcoma model was a PEGylated nanocochleate formulation. These findings provide a foundation for developing more effective formulations and chemotherapeutic strategies for the treatment of fibrosarcoma and other types of cancer.

RESUMO

INTRODUCTION: Acute musculoskeletal injuries are one of the most common painful presentation when admission to the emergency department. The aim of the study is to compare the tenoxicam mesotherapy with intravenous dexketoprofen in pain control in patients with acute musculoskeletal injury. METHODS: This parallel randomized controlled trial was conducted with the patients admitted to the emergency department with musculoskeletal injury. Intravenous dexketoprofen was administered to the control group, and mesotherapy treatment was performed to the other group. Differences between 10th, 30th, 60th and 120th minutes VAS scores and on the admission VAS score, clinically meaningful change in pain intensity, and adverse effect of the procedures were compared among groups. THE RESULTS: The differences in VAS scores and the presence of clinically meaningful change in pain intensity were statistically significantly higher in mesotherapy group than the systemic therapy group in all time periods. During one-week follow-up period, there was no reported adverse effect neither in mesotherapy group nor in the systemic therapy group. CONCLUSIONS: The mesotherapy treatment may be superior than the systemic therapy for pain relief in musculoskeletal injury in short term follow-up in emergency department settings.

RESUMO

OBJECTIVES: To compare efficacy/safety of oral tramadol 75 mg/dexketoprofen 25 mg (TRAM/DKP) and TRAM 75 mg/paracetamol 650 mg (TRAM/paracetamol) in moderate to severe pain following surgical removal of impacted lower third molar. DESIGN: Multicentre, randomised, double-blind, placebo-controlled, phase IIIb study. PARTICIPANTS: Healthy adult patients scheduled for surgical extraction of at least one fully/partially impacted lower third molar requiring bone manipulation. 654 patients were randomised and 653 were eligible for analysis. INTERVENTIONS: Surgery was performed under local anaesthetic. No sedation was permitted. Patients rated pain intensity (PI) using an 11-Numerical Rating Scale (NRS) (0 no pain; 10 worst pain). Participants experiencing moderate/severe pain (≥4) within 4 hours of surgery were randomised (2:2:1 ratio) to a single oral dose of TRAM/DKP 75/25 mg, TRAM/paracetamol 75/650 mg or placebo. MAIN OUTCOME MEASURES: Efficacy was based patients' electronic diaries. Analgesia and pain were recorded as follows: pain relief (PAR) on a 5-point Verbal Rating Scale (0='no relief', 1='a little (perceptible) relief', 2='some (meaningful) relief', 3='lot of relief', 4='complete relief') at the predefined postdose time points t15 min, t30 min, t1 hour, t1.5 hour, t2 hour, t4 hour, t6 hour and t8 hour and PI on the 11-point NRS at t0 and at the same predefined postdose time points. Onset of analgesia documented using double stopwatch method over a 2-hour period. Primary endpoint was total pain relief over 6 hours (TOTPAR6). Rescue medication was available during the treatment period. RESULTS: TRAM/DKP was superior to TRAM/paracetamol and placebo at the primary endpoint TOTPAR6 (p<0.0001). Mean (SD) TOTPAR6 in the TRAM/DKP group was 13 (6.97), while those in the active control and placebo groups were 9.2 (7.65) and 1.9 (3.89), respectively. Superiority of TRAM/DKP over active comparator and placebo was observed at all secondary endpoints. Incidence of adverse events was comparable between active groups. CONCLUSIONS: TRAM/DKP (75/25 mg) is effective and superior to TRAM/paracetamol (75/650 mg) in relieving moderate to severe acute pain following surgical removal of impacted lower third molar, with a faster onset of action, greater and durable analgesia, together with a favourable safety profile. TRIAL REGISTRATION NUMBER: EudraCT 2015-004152-22 and NCT02777970.

RESUMO

INTRODUCTION: Although acute musculoskeletal pain has a wide range of causes from tendinitis, muscle spasm, to bone and joint injuries, it is a frequent occurrence in emergency services. Paracetamol and non-steroidal anti-inflammatory analgesics (NSAID) are common used in the treatment of musculoskeletal pain. This study sets out to compare the effectiveness of intravenous dexketoprofen and paracetamol in musculoskeletal pain relief. METHODS: This prospective, randomized, double blind, controlled study was carried out in a university emergency room. The participating patients were randomized into two groups to receive either 50 mg of dexketoprofen or 1000 mg of paracetamol intravenously by rapid infusion in 150 ml of normal saline. Visual analogue scale (VAS), Numeric Rating Scala (NRS) was employed for pain measurement at baseline, after 15, after 30 and after 60 mins. RESULTS: 200 patients were included in the study, excluding 7342 of them. The mean age of the patients was calculated as 32,6. Paracetamol and dexketoprofen intervention decreases NRS pain scores over time. When compared to all pain locations, the NRS pain score of the patients was found to be statistically more effective in dexketoprofen than in paracetamol (p = 0.001). Paracetamol and dexketoprofen intervention reduces pain VAS scores over time. When the VAS pain score of the patients was compared to all pain locations, dexketoprofen was found to be statistically more effective than paracetamol (p = 0.001). CONCLUSION: Intravenous dexketoprofen seemed to achieve superior analgesia to intravenous paracetamol when compared with all pain locations in patients with non-traumatic musculoskeletal pain.

RESUMO

Background: Postoperative pain is one of the most common complications. The aim of this study is to evaluate the analgesic efficacies of dexketoprofen trometamol and two different dosages of dexketoprofen trometamol + thiocolchicoside combination in the impacted third molar tooth operation. Material and Methods: This randomized, double-blind study included 75 patients who did not have any disease. Patients were assigned to 3 groups. Group 1 received 25 mg dexketoprofen trometamol + 4 mg thiocholchicoside, Group 2 received 25 mg dexketoprofen trometamol +8 mg thiocholchicoside, and Group 3 received 25 mg dexketoprofen trometamol. In each group, the analgesic medication was administered twice a day, starting 1 hour before the operation. The level of pain was assessed with VAS. Results: Patient age varied from 18 to 36 years. Of all patients, 59.2% (n=42) were female and 40.8% (n=29) were male. Drug side effects were observed in 28.17% (n=20) of the patients. Mean 24th hour VAS score was lower in dexketoprofen trometamol + 8 mg thiocolchicoside group compared to dexketoprofen trometamol group (p<0.05). There was no statistically significant difference between the three groups regarding drug side effects (p>0.05). Conclusions: Dexketoprofen trometamol + 8 mg thiocolchicoside combination has higher analgesic efficacy compared to dexketoprofen trometamol. More studies are needed to interpret the analgesic and anti-inflammatory effects of thiocholchicoside + dexketoprofen trometamol combination

RESUMO

Motherwort (YiMuCao), a traditional Chinese herb, has been shown beneficial effects for women's diseases. This meta-analysis aimed to evaluate the efficacy and safety of motherwort injection add-on therapy to carboprost tromethamine for prevention of post-partum blood loss. A systematic literature search was conducted in PubMed, Embase, Cochrane Library, CNKI, VIP and Wanfang from their inception to December 2017. Randomized controlled trials that determined the add-on effects of motherwort injection to carboprost for prevention of post-partum blood loss were eligible. Pooled risk ratio (RR) and mean difference (MD) with 95% confidence interval (CI) were used to summarize the effect sizes. Eight trials including 1276 pregnant women fulfilled the inclusion criteria. Prophylactic use of motherwort injection add-on therapy significantly reduced the post-partum 2 h (MD -127.5 mL; 95% CI -149.13 to -105.88) and 24 h (MD -146.85 mL; 95% CI -179.77 to -113.94) blood loss and incidence of post-partum hemorrhage (RR 0.28; 95% CI 0.17-0.45) than carboprost. Moreover, adjunctive treatment with motherwort injection significantly decreased the length of the third stage of labor (MD -3.41 min; 95% CI -4.33 to -2.49) and duration of lochia (MD -7.13 days; 95% CI -8.49 to -5.76). There was no statistical significant difference in the incidence of adverse events (RR 0.76; 95% CI 0.50-1.16). Prophylactic use of motherwort injection add-on therapy to carboprost tromethamine could reduce post-partum blood loss. However, more well-designed trials are necessary to confirm the findings of this study due to the methodological flaws of the included trials.

RESUMO

INTRODUCTION: Musculoskeletal system traumas are among the most common presentations in the emergency departments. In the treatment of traumatic musculoskeletal pain, paracetamol and non-steroidal anti-inflammatory analgesics (NSAID) are frequently used. Our aim in this study is to compare the efficacy of intravenous dexketoprofen and paracetamol in the treatment of traumatic musculoskeletal pain. METHODS: This prospective, randomised, double blind, controlled study was conducted in a tertiary care emergency unit. The participating patients were randomised into two groups to receive either 50 mg of dexketoprofen or 1000 mg of paracetamol intravenously by rapid infusion in 150 mL of normal saline. Visual analogue scale (VAS), Numeric Rating Scala (NRS) and Verbal Rating Scale (VRS) was employed for pain measurement at baseline, after 15, after 30 and after 60 mins. RESULTS: 200 patients were included in the final analysis. The median age of the paracetamol group was 34 (24-48), while that of the dexketoprofen group was 35 (23-50), and 63% (n = 126) of them consisted of men. Paracetamol and dexketoprofen administration reduced VAS pain scores over time (p = 0.0001). Median reduction in VAS score at 60 min was 55 (IQR 30-65) for the paracetamol group and 50(IQR 30.25-60) for the dexketoprofen group. There was no statistically significant difference between the paracetamol and dexketoprofen groups in terms of VAS reductions (p = 0.613). CONCLUSION: Intravenous paracetamol and dexketoprofen seem to produce equivalent pain relief for acute musculoskeletal trauma in the emergency department. CLINICALTRIALS. GOV NO: NCT03428503.
