RESUMO

Multimodal analgesia is defined as using several drugs or techniques simultaneously to target different pain pathways or receptors to avoid pain propagation. This study evaluated the pharmacokinetic profile and comparative bioavailability of etoricoxib 90 mg and tramadol 50 mg dosing alone (reference drugs) or in a novel fixed-dose combination (test drug) under fasting conditions in Mexican healthy volunteers. This was a randomized, open-label, 3-way, crossover, single-dose, prospective, and longitudinal study with a 14-day washout period. Eligible subjects were healthy Mexican adult volunteers. The drugs were dosing orally, according to the randomization sequence, after 10 hours of fasting and 4 hours before breakfast with 250 mL of water at room temperature. Serial blood samples were collected before and after dosing, both drugs were quantified using high-performance liquid chromatography coupled with tandem mass spectrometry. Forty-two subjects were enrolled and 38 completed the study (28 men and 14 women, mean age 25.2 years, mean weight 66.6 kg). Test products were considered to have comparative bioavailability if confidence intervals of natural log-transformed for (maximum plasma drug concentration (Cmax), (area under the plasma drug concentration-time curve form 0 up to last sampling time (AUC0-t), and (area under the plasma drug concentration-time curve from 0 up to infinity (AUC0-∞) data were within the range of 80%-125%. Non-serious adverse events were observed. The results demonstrate that the pharmacokinetic profile and bioavailability of the etoricoxib/tramadol fixed-dose combination are comparable to those of the reference products.

RESUMO

BACKGROUND: Musculoskeletal disorders are an important cause of work absence. Clinical practice guidelines recommend nonsteroidal anti-inflammatory drugs (NSAIDs) for grade I-II cervical sprains. The combination of thiamine + pyridoxine + cyanocobalamin vitamins has been used, alone and in combination with NSAIDs, for pain and inflammation in musculoskeletal disorders. OBJECTIVE: The objective of this study was to demonstrate the analgesic synergy of dexketoprofen, and the combination of vitamins thiamine + pyridoxine + cyanocobalamin in a fixed-dose combination (FDC) for the treatment of acute pain caused by grade I-II cervical sprains. METHODS: We conducted a multicentre, prospective, randomized, double-blind, phase IIIb clinical study comparing two treatment groups: (1) dexketoprofen 25 mg/vitamin B (thiamine 100 mg, pyridoxine 50 mg and cyanocobalamin 0.50 mg) in an FDC (two or more active ingredients combined in a single dosage form) versus (2) dexketoprofen 25 mg monotherapy (single drug to treat a particular disease), one capsule or tablet orally, every 8 h for 7 days. Final mean, average change, and percentage change in pain perception (measured using a visual analogue scale [VAS]) were compared with baseline between groups. A p value < 0.05 was considered statistically significant. Analyses were conducted using SPSS software, v.29.0. RESULTS: A statistically significant reduction in pain intensity was observed from the third day of treatment with the FDC compared with monotherapy (- 3.1 ± - 1.5 and - 2.6 ± - 1.1 cm, respectively) measured using the VAS (p = 0.011). Regarding the degree of disability, using the Northwick Park Neck Pain Questionnaire (NPQ), statistical difference was observed for the final measurement (7.5%, interquartile range [IQR] 2.5, 10.5; vs. 7.9%, IQR 5.0, 13.8; p = 0.028). A lower proportion of adverse events was reported when using the FDC. CONCLUSIONS: The FDC of dexketoprofen/thiamine + pyridoxine + cyanocobalamin vitamins demonstrated superior efficacy and a better safety profile compared with dexketoprofen monotherapy for pain treatment in patients with grade I-II cervical sprains.

RESUMO

Introduction: Cardiovascular diseases are the leading cause of death worldwide. The combination of statins and cholesterol-absorption inhibitors promotes the decrease in risk factors, such as high concentrations of LDL (low-density lipoproteins). The aim of the study was to evaluate changes in the lipid profile and the effect on therapeutic goals, as well as the safety of dyslipidemia patients treated with Rosuvastatin/Ezetimibe (Trezete®). Materials and Methods: A real-world evidence study was conducted with retrospective data collection through a review of clinical records from dyslipidemia patients treated with Trezete® in routine medical practice. Clinical records included results of biochemical markers before treatment and at least one follow up between weeks 8 and 16. Results: The study included 103 patients' clinical records (55.4% men) with a mean age of 56.0 ± 13.0 years. More than 57% of the patients had mixed dyslipidemia and a median disease progression of 3.1 (IQR, 1.5; 9.1) years. Regarding LDL concentrations, 72.8% of the patients achieved therapeutic goals according to cardiovascular risk (CVR), which was statistically significant. Similarly, 94.1% achieved goals for total cholesterol (<200 mg/dL) and 56.0% for triglycerides (<150 mg/dL), a p value <0.001. No cardiovascular events were observed. Conclusion: Trezete® shows an important clinical impact on CVR-related target markers during the treatment of dyslipidemia patients. It is relevant to mention that a significant percentage of patients achieved therapeutic goals during the first months of treatment. Fixed-dose combination therapy has shown to be as safe as monotherapy treatment. ClinicalTrials.gov Identifier: NCT04862962.
