A randomized controlled trial evaluating the short-term efficacy of a single-administration intramuscular injection with the fixed combination of thiocolchicoside-diclofenac versus diclofenac monotherapy in patients with acute moderate-to-severe low back pain.

BACKGROUND: Non-specific acute low back pain (LBP) is a common health problem that may be accompanied by muscle spasm and decreased mobility. The combination of non-steroidal anti-inflammatory drugs and muscle relaxants represents an advantageous therapeutic option, however, available data on their combined use are conflicting. This prospective, randomized, single-blind, two-parallel-group trial assessed the efficacy of a single intramuscular (IM) injection of the fixed-dose combination (FDC) diclofenac (75 mg)-thiocolchicoside (4 mg/4 ml) product (test treatment) compared to diclofenac (75 mg/3 ml) alone (reference treatment) for the symptomatic relief of acute LBP. Tolerability and safety were also assessed as secondary variables. METHODS: One hundred thirty-four patients were enrolled (safety population) and randomly allocated to the combination or single-agent regimen. Pain intensity and muscle spasm, assessed respectively by the patient-reported visual analogue scale and investigator-performed finger-to-floor distance test, were determined prior to the injection as well as 1 and 3 h post-injection in 123 patients (per-protocol population). The patients were blinded to treatment. Safety was assessed up to 24 h post-injection. RESULTS: The test treatment was superior in both alleviating the pain intensity and reducing the finger-to-floor distance at both 1 (p < 0.01 and p = 0.023 respectively) and 3 h post-injection (p < 0.01). A higher percentage of patients experienced > 30% reduction in pain intensity at 1 and 3 h with the test treatment (p = 0.037 and p < 0.01 respectively). The corresponding VAS (SD) scores for the test treatment group were at baseline, 1 and 3 h post-injection 72.03 (± 11.72), 45.37 (± 16.28) and 31.56 (± 15.08) respectively and for the reference treatment group 65.20 (± 12.16), 48.98 (± 18.76) and 44.52 (± 17.33) respectively. No adverse effects were reported with the combination treatment, whereas two patients treated with diclofenac reported dizziness. CONCLUSIONS: The FDC treatment is an effective and well-tolerated option for the symptomatic treatment of LBP. Clinical and patient-reported assessments confirmed that a single IM injection of FDC diclofenac-thiocolchicoside was more effective than diclofenac alone in conferring rapid and sustained improvement in mobility and pain intensity.

Beneficial Effect of Flecainide Controlled Release on the Quality of Life of Patients with Atrial Fibrillation-the REFLEC-CR Study.

PURPOSE: Atrial fibrillation (AF) is the most common cardiac arrhythmia with a considerable impact on patients' quality of life (QoL). METHODS: This prospective, multicenter, observational study aimed to evaluate the effect of oral treatment with controlled-release (CR) flecainide on AF patients' QoL and treatment compliance during a 12-week period. A total of 70 sites enrolled consecutive patients with paroxysmal (PAF) or persistent AF (PerAF), treated with flecainide CR in the context of a rhythm control strategy. The effect on QoL was assessed by the Canadian Cardiovascular Society Severity of Atrial Fibrillation scale (CCS-SAF). RESULTS: In total, 679 patients (53.2% females, 66 ± 11.7 years, 86.9% PAF) were included. Prior antiarrhythmic medication had been administered in 43.8% of patients. A daily dose of 200 mg was administered to 66.4% of patients by the end of study. Flecainide CR resulted in a significant reduction in the CCS-SAF score (mean (SD)) at the end of the study as compared with baseline (1.32 (0.57) vs 1.64 (0.73), p < 0.0001). Flecainide CR significantly reduced the CCS-SAF score both in PAF (1.27 (0.52) vs 1.61 (0.72), p < 0.0001) as well as in PerAF (1.63(0.77) vs 1.84(0.81), p = 0.017). Overall, 4 (0.6%) patients experienced a total of 6 adverse events during the study period. The compliance to flecainide CR treatment was very high with 93.6% of patients responding that they had not missed any dose during the study period. CONCLUSION: Treatment with flecainide CR significantly improves QoL in both paroxysmal as well as persistent AF patients, with an excellent safety profile and associated patient compliance.

Real world data from a multi-centre study on the effects of cilostazol on pain symptoms and walking distance in patients with peripheral arterial disease.

OBJECTIVE: to assess the effects of cilostazol on pain-free walking distance in PAD patients with IC at 3 and 6 months in a real world, prospective, observational study. We included 1015 PAD patients presenting with IC (71.3% men, 93.5% white, mean age 69.2 ± 8.7 years). Patients were followed up for 6 months by their physicians. RESULTS: Cilostazol significantly increased pain-free walking distance by a median of 285 and 387 m at 3 and 6 months, respectively (p < 0.01 for all comparisons). This effect was significant for patients 50-74 years (but not for those aged ≥ 75 years) and independent of smoking status, changes in physical activity, comorbidities and concomitant medication for PAD (i.e., acetylsalicylic acid and clopidogrel). Furthermore, significant reductions were observed in systolic (from 139 ± 16 to 133 ± 14 mmHg; p < 0.001) and diastolic blood pressure (from 84 ± 9 mmHg to 80 ± 10 mmHg; p < 0.001). Smoking cessation and increased physical activity were reported by the majority of participants. In conclusion, cilostazol was shown to safely decrease pain symptoms and improve pain-free walking in PAD patients with IC in a real world setting. Benefits also occurred in terms of BP and lifestyle changes.
