A clinical trial comparing Lanconone® with ibuprofen for rapid relief in acute joint pain.

ABSTRACT: To study the effect of Lanconone® (1000 mg) on acute pain on exertion as compared to the standard of care, Ibuprofen (400 mg).The study recruited 72 subjects diagnosed with mild to moderate knee joint pain on exertion. Subjects with Pain Visual Analogue Scale of more than 40 mm were included. Uphill walking was provided as the stressor using Naughton's protocol on a treadmill. The subjects walked for 10 minutes continuously followed by a rest period and baseline pain score for index knee joint was recorded. Subjects were administered a single dose of Lanconone® (1000 mg)/Ibuprofen (400 mg). Thereafter the same stressor was provided at 0.5, 1, 2, 3, 4, and 6 hours, subsequently, pain scores were recorded on a visual analogue scale. Double stopwatch method was used to evaluate the onset of pain relief and time taken to meaningful pain relief.Both Lanconone® and Ibuprofen showed the first perceived pain relief at 65.31?±?35.57 mins as compared to 60.82?±?32.56 mins respectively. The mean time taken to experience meaningful pain relief in Lanconone® group was 196.59?±?70.85 mins compared to 167.13?±?71.41 mins amongst Ibuprofen group. The meaningful pain relief continued for 6 hours.The current study successfully demonstrated rapid pain-relieving potential of Lanconone® which was comparable to Ibuprofen. No adverse event related to the interventions was reported in the study.Clinical trials.gov NCT02417506 . 21 January 2015.

Project description:IntroductionIbuprofen acid is poorly soluble in the stomach, thus reaching maximum plasma levels at approximately 90 min post-dose. Ibuprofen lysinate has been developed to accelerate absorption of ibuprofen to shorten the time to analgesic efficacy. This study compared analgesic efficacy and onset of effect of a single dose of ibuprofen lysinate or ibuprofen acid in patients undergoing third molar extraction.MethodsRandomized, double-blind, placebo-controlled, multi-center, parallel-group single-dose study. Adults (18-60 years) undergoing extraction of ≥ 1 third molar were randomized 2:2:1 to ibuprofen lysinate, ibuprofen acid, or placebo postoperatively. Pain relief (PAR, 5-point scale, 0 = none to 4 = complete pain relief) and pain intensity (PI, 100 mm visual analog scale) were assessed between 15 and 360 min post-dose. The primary endpoint was the weighted sum of PAR scores at 6 h (TOTPAR). Time to onset of effect, global assessment of efficacy, and adverse events were also assessed.ResultsOverall, 351 patients received ibuprofen lysinate (N = 141), ibuprofen acid (N = 139), or placebo (N = 71). Both active treatments significantly reduced pain compared with placebo, from 15 min post-dose to 6 h (TOTPAR: ibuprofen lysinate: 19.57; ibuprofen acid: 19.96; placebo: 8.27). Ibuprofen lysinate was significantly more effective than placebo, but non-inferior to ibuprofen acid, at providing pain relief over 6 h. There was no significant difference between ibuprofen lysinate and ibuprofen acid for onset of analgesia. Both ibuprofen formulations were well tolerated; all adverse events were mild to moderate and considered unrelated to treatment.ConclusionsA single dose of ibuprofen lysinate is non-inferior to ibuprofen acid in terms of analgesic efficacy, onset of action, and tolerability in patients who have recently undergone dental surgery.Trial registrationEudraCT No. 2006-006942-33.

Project description:ObjectiveTo evaluate the analgesic efficacy and safety of different does of intravenous ibuprofen (IVIB) in the treatment of postoperative acute pain.MethodsPatients with an intravenous (IV) patient-controlled analgesia device after abdominal or orthopedic surgery were randomly divided into placebo, IVIB 400 mg, and IVIB 800 mg groups. The first dosage of study medicines was given intravenously 30 minutes (min) before surgery ended, followed by six hours (h) intervals for a total of eight doses following surgery. The demographic characteristics and procedure data, cumulative morphine consumption, the visual analog scale (VAS), the area under the curve (AUC) of VAS, patient satisfaction score (PSS), the rates of treatment failure (RTF), and adverse events (AEs) and serious adverse event (SAEs) were recorded during the period of trial.ResultA total of 345 patients were enrolled in the full analysis set (FAS), and of 326 participants were valid data set (VDS). Demographic characteristics, disease features, and medical history of patients were not significantly different between groups. Total morphine consumption of the IVIB 400 mg group (11.14 ± 7.14 mg; P = 0.0011) and the IVIB 800 mg group (11.29 ± 6.45 mg; P = 0.0014) was significantly reduced compared with the placebo group (14.51 ± 9.19 mg) for 24 h postoperatively, there was no significant difference between the IVIB 400 mg and IVIB 800 mg groups (P = 0.9997). The placebo group had significantly higher VAS and the AUCs of VAS than those in the IVIB 400 mg and the IVIB 800 mg groups at rest and movement for 24 h postoperatively (P < 0.05), and there was no significant difference between the IVIB 400 mg and IVIB 800 mg groups (P > 0.05). RTF was slightly higher in the placebo group than IVIB 400 mg group and 800 mg group, and no statistical significance (P < 0.690). PSS in the IVIB 400 mg (P = 0.0092) and the IVIB 800 mg groups (P = 0.0011) was higher than the placebo group for pain management, there was also no significant difference between the IVIB 400 mg and IVIB 800 mg groups (P = 0.456). The incidence of RTF (P = 0.690) and AEs (P > 0.05) were not different among the three groups.ConclusionIntermittent IV administration of ibuprofen 400 mg or 800 mg within 24 h after surgery in patients undergoing abdominal and orthopedic surgery significantly decreased morphine consumption and relieved pain, without increasing the incidence of AEs.

Project description:ImportanceRenal colic is described as one of the worst types of pain, and effective analgesia in the shortest possible time is of paramount importance.ObjectivesTo examine whether acupuncture, as an adjunctive therapy to analgesics, could accelerate pain relief in patients with acute renal colic.Design, setting, and participantsThis single-center, sham-controlled, randomized clinical trial was conducted in an emergency department in China between March 2020 and September 2020. Participants with acute renal colic (visual analog scale [VAS] score ≥4) due to urolithiasis were recruited. Data were analyzed from October 2020 to January 2022.InterventionsAfter diagnosis and randomization, all patients received 50 mg/2 mL of diclofenac sodium intramuscular injection immediately followed by 30-minute acupuncture or sham acupuncture.Main outcomes and measuresThe primary outcome was the response rate at 10 minutes after needle manipulation, which was defined as the proportion of participants whose VAS score decreased by at least 50% from baseline. Secondary outcomes included response rates at 0, 5, 15, 20, 30, 45, and 60 minutes, rescue analgesia, and adverse events.ResultsA total of 115 participants were screened and 80 participants (66 men [82.5%]; mean [SD] age, 45.8 [13.8] years) were enrolled, consisting of 40 per group. The response rates at 10 minutes were 77.5% (31 of 40) and 10.0% (4 of 40) in the acupuncture and sham acupuncture groups, respectively. The between-group differences were 67.5% (95% CI, 51.5% to 83.4%; P < .001). The response rates of acupuncture were also significantly higher than sham acupuncture at 0, 5, 15, 20 and 30 minutes, whereas no significant difference was detected at 45 and 60 minutes. However, there was no difference between the 2 groups in rescue analgesia rate (difference 2.5%; 95% CI -8.8% to 13.2%; P > .99). No adverse events occurred during the trial.Conclusions and relevanceThese findings suggest that acupuncture plus intramuscular injection of diclofenac is safe and provides fast and substantial pain relief for patients with renal colic compared with sham acupuncture in the emergency setting. However, no difference in rescue analgesia was found, possibly because of the ceiling effect caused by subsequent but robust analgesia of diclofenac. Acupuncture can be considered an optional adjunctive therapy in relieving acute renal colic.Trial registrationChinese Clinical Trial Registry: ChiCTR1900025202.

Project description:IntroductionThis study aims to investigate the effectiveness of intravenous ibuprofen or intravenous ibuprofen plus acetaminophen compared to intravenous morphine in patients with closed extremity fractures.MethodsA triple-blinded randomized clinical trial was conducted at a tertiary trauma center in Iran. Adult patients between 15 and 60 years old with closed, isolated limb fractures and a pain intensity of at least 6/10 on the visual analog scale (VAS) were eligible. Patients with specific conditions or contraindications were not included. Participants were randomly assigned to receive intravenous ibuprofen, intravenous ibuprofen plus acetaminophen, or intravenous morphine. Pain scores were assessed using the visual analog scale at baseline and 5, 15, 30, and 60 min after drug administration. The primary outcome measure was the pain score reduction after one hour.ResultsOut of 388 trauma patients screened, 158 were included in the analysis. There were no significant differences in age or sex distribution among the three groups. The pain scores decreased significantly in all groups after 5 min, with the morphine group showing the lowest pain score at 15 min. The maximum effect of ibuprofen was observed after 30 min, while the ibuprofen-acetaminophen combination maintained its effect after 60 min. One hour after injection, pain score reduction in the ibuprofen-acetaminophen group was significantly more than in the other two groups, and pain score reduction in the ibuprofen group was significantly more than in the morphine group.ConclusionThe study findings suggest that ibuprofen and its combination with acetaminophen have similar or better analgesic effects compared to morphine in patients with closed extremity fractures. Although morphine initially provided the greatest pain relief, its effect diminished over time. In contrast, ibuprofen and the ibuprofen-acetaminophen combination maintained their analgesic effects for a longer duration. The combination therapy demonstrated the most sustained pain reduction. The study highlights the potential of non-opioid analgesics in fracture pain management and emphasizes the importance of initiation of these medications as first line analgesic for patients with fractures. These findings support the growing trend of exploring non-opioid analgesics in pain management.Trial registrationClinicalTrials.gov Identifier: NCT05630222 (Tue, Nov 29, 2022).

Project description:Study objectivePatients with low back pain are often treated with nonsteroidal anti-inflammatory drugs and skeletal muscle relaxants. We compare functional outcomes and pain among patients with acute low back pain who were randomized to a 1-week course of ibuprofen plus placebo versus ibuprofen plus 1 of 3 skeletal muscle relaxants: baclofen, metaxalone, and tizanidine.MethodsThis was a randomized, double-blind, parallel-group, 4-arm study conducted in 2 urban emergency departments (EDs). Patients with nonradicular low back pain for less than or equal to 2 weeks were eligible if they had a score greater than 5 on the Roland-Morris Disability Questionnaire, a 24-item inventory of functional impairment caused by low back pain. All participants received 21 tablets of ibuprofen 600 mg, to be taken 3 times a day as needed. Additionally, they were randomized to baclofen 10 mg, metaxalone 400 mg, tizanidine 2 mg, or placebo. Participants were instructed to take 1 or 2 of these capsules 3 times a day as needed. All participants received a 10-minute educational session. The primary outcome was improvement on the Roland-Morris Disability Questionnaire between ED discharge and 1week later. Secondary outcomes included pain intensity 1 week after ED discharge (severe, moderate, mild, or none).ResultsThree hundred twenty patients were randomized. One week later, the mean Roland-Morris Disability Questionnaire score of patients randomized to placebo improved by 11.1 points (95% confidence interval [CI] 9.0 to 13.3), baclofen by 10.6 points (95% CI 8.6 to 12.7), metaxalone by 10.1 points (95% CI 8.0 to 12.3), and tizanidine by 11.2 points (95% CI 9.2 to 13.2). At 1-week follow-up, 30% of placebo patients (95% CI 21% to 41%) reported moderate to severe low back pain versus 33% of baclofen patients (95% CI 24% to 44%), 37% of metaxalone patients (95% CI 27% to 48%), and 33% of tizanidine patients (95% CI 23% to 44%).ConclusionAdding baclofen, metaxalone, or tizanidine to ibuprofen does not appear to improve functioning or pain any more than placebo plus ibuprofen by 1 week after an ED visit for acute low back pain.

Project description:In this study, we performed a phase I and II clinical trial in dogs to evaluate the toxicity and immunogenicity of LBSap-vaccine prototype, in comparison to Leishmune® and Leish-Tec® vaccines. Twenty-eight dogs were classified in four groups: (i) control group received 1 mL of sterile 0.9% saline solution; (ii) LBSap group received 600 μg of Leishmania braziliensis promastigotes protein and 1 mg of saponin adjuvant; (iii) Leishmune®; and (iv) Leish-Tec®. The safety and toxicity of the vaccines were measured before and after three immunizations by clinical, biochemical, and hematological parameters. The clinical examinations revealed that some dogs of LBSap and Leishmune® groups presented changes at the site of vaccination inoculum, such as nodules, mild edema, and local pain, which were transient and disappeared seventy-two hours after vaccination, but these results indicate that adverse changes caused by the immunizations are tolerable. The immunogenicity results demonstrate an increase of B lymphocytes CD21+ regarding the Leishmune® group and monocytes CD14+ concerning LBSap and Leishmune® groups. In the in vitro analyses, an increase in lymphoproliferative activity in LBSap and Leishmune® groups was observed, with an increase of antigen-specific CD4+ and CD8+ T lymphocytes in the LBSap group. A second approach of in vitro assays aimed at evaluating the percentage of antigen-specific CD4+ and CD8+ T lymphocytes producers of IFN-γ and IL-4, where an increase in both IFN-γ producing subpopulations in the LBSap group was observed, also showed an increase in IFN-γ producers in CD8+ lymphocytes in the Leish-Tec® group. Our data regarding immunogenicity indicate that the vaccination process, especially with the LBSap vaccine, generated a protective immune response compatible with L. infantum parasite control. Based on the foregoing, the LBSap vaccine would be suitable for further studies of phase III clinical trial in endemic areas with high prevalence and incidence of canine visceral leishmaniasis (VL) cases.
