Chinese herbal medicine is associated with higher body weight reduction than liraglutide among the obese population: A real-world comparative cohort study.

Introduction: In Taiwan, many people receive Chinese herbal medicine (CHM) as an alternative choice to help control body weight. However, the clinical effectiveness of CHM on weight control has not been well studied, while potential risks and adverse effects are still unknown. The aim of our study is to find out a safe and efficient treatment model of CHM for weight control compared to liraglutide in a real-world setting. Methods: we retrospectively analyzed obese subjects [body mass index (BMI)≧25 kg/m2] from Chang Gung Research Database (2013-2018). We evaluated the effect on body weight and BMI changes in obese groups receiving CHM or western medicine (WM, represented liraglutide) within 180 days. The proportion of subjects who achieved 5 and 10% weight reduction was calculated as well. Furthermore, the potential adverse events were analyzed during the study period. Overlap weighting was used to balance the baseline differences between CHM and WM groups. Results: The full cohort comprised 1,360 participants: 701 in the CHM group and 659 in the WM group. At baseline, the CHM group was younger (42.75 ± 12.12 years old in CHM vs. 52.31 ± 11.7 years old in WM, p-value <0.001) and has more female subjects (77.6% in CHM vs. 53.0% in WM, p-value <0.001). On the other hand, CHM users had lower body weight (79.83 ± 15.66 kg vs. 84.68 ± 17.14 kg, p-value <0.001) and BMI (30.58 ± 5.20 vs. 32.84 ± 6.95, p-value <0.001). At day 180, CHM users lost more body weight (-4.5 ± 4.07 kg vs. -2.15 ± 4.05 kg, p-value <0.001) and higher reduction in BMI (-1.77 ± 1.73 vs. -0.9 ± 2.14, p-value <0.001). A total of 53.21% (n = 373) CHM users lost at least 5% of body weight (22.46% for WM users, p-value <0.001), and 18.97% (n = 132) lost at least 10% of body weight (4.55% for WM users, p-value <0.001). The benefit remained consistent with and without overlap weighting. For adverse events, 18 cases of hypertension occurred in 659 subjects in the WM group (2.7%) in comparison to 1 of 701 subjects in the CHM group (0.1%). Conclusion: CHM led to clinically meaningful weight loss without serious adverse events in a real-world setting. Further clinical trials are warranted to validate this result.

Targeting ERα degradation by L-Tetrahydropalmatine provides a novel strategy for breast cancer treatment.

The incidence and mortality of breast cancer (BCa) are the highest among female cancers. There are approximate 70% BCa that are classified as estrogen receptor alpha (ERα) positive. Therefore, targeting ERα is the most significantly therapeutic schedule. However, patients with breast cancer develop resistance to ERα or estrogen (E2) antagonists such as fulvestrant and tamoxifen. In the present study, we found that L-Tetrahydropalmatine (L-THP) significantly suppressed cell proliferation in ERα+ BCa cells via inducing cell cycle arrest rather than apoptosis. Additionally, L-THP enhanced the sensitivity of ERα+ BCa cells to tamoxifen and fulvestrant. Mechanically, the application of L-THP promotes ERα degradation through accumulating ubiquitin chains on ERα. Overexpressing ERα abrogates L-THP induced-antiproliferation in ERα+ BCa cells. Collectively, our work indicates that L-THP may represent a potentially novel therapeutic medicine for ERα+ breast cancer patient.

Comparative effects of fexofenadine and montelukast on allergen-induced wheal and flare.

Comparisons of the efficacy, onset and duration of action of fexofenadine and montelukast are limited. This study evaluated the pharmacodynamic properties of these agents in an allergen-induced wheal-and-flare model. This randomized, placebo-controlled, crossover study was composed of three treatment periods and two visits on consecutive days for each period, with each period separated by a 14-day (+/-4) washout. At each treatment visit, subjects received a predose allergen skin-prick test followed by either a single dose of fexofenadine HCl 180 mg, montelukast sodium 10 mg, or placebo. Allergen skin-prick testing was performed at 20, 40, and 60 minutes, then hourly through 12 hours and at 23 hours and 24 hours postdose. Adults (n = 48) with positive skin-prick tests were included in the analysis. Significant flare inhibition occurred from 40 minutes through 24 hours postdose for fexofenadine versus placebo (p < 0.05), whereas montelukast did not reach statistical significance for flare inhibition at any time point compared with placebo. Significant wheal inhibition occurred from 60 minutes through 24 hours postdose for fexofenadine versus placebo (p = 0.0012); montelukast did not significantly suppress wheal versus placebo at any time point. Fexofenadine had greater suppression than montelukast for both wheal and flare from 40 minutes through 24 hours (p < .05). Maximum suppression of flare and wheal reached 79.0 and 72.3% for fexofenadine, and 7.3 and 9.6% for montelukast. Fexofenadine suppressed the allergen-induced wheal-and-flare response to a significantly greater extent, and had a significantly faster onset of action, compared with montelukast.

Fexofenadine HCl 60 mg/ pseudoephedrine HCl 120 mg has a 60-minute onset of action in the treatment of seasonal allergic rhinitis symptoms, as assessed in an allergen exposure unit.

Although antihistamine-decongestant combinations are frequently used for allergic rhinitis, published data about the onset of action of these combination agents are limited. This randomized, double-blind, placebo-controlled, parallel-group study investigated the onset of action, efficacy, and safety of fexofenadine HCl 60 mg/pseudoephedrine HCl 120 mg or placebo in patients with moderate-to-severe seasonal allergic rhinitis in an allergen exposure unit. Assessments included major symptom complex (MSC) score (sum of sneezing, itchy nose, runny nose, watery eyes, itchy eyes, itchy ears/throat, and stuffy nose), and total symptom complex (TSC) score (MSC symptoms plus nose blows, sniffles, postnasal drip, and cough). Onset of action was defined as the first time that two consecutive, statistically significant absolute changes in MSC scores from baseline were achieved for study drug relative to placebo. The onset of action for the combination was 60 minutes (mean absolute MSC change from baseline: -6.9 +/- 0.3 for the combination compared with -5.9 +/- 0.3 for placebo from a baseline of 17.0 and 16.8, respectively; p < 0.05) for the modified intention-to-treat population (n = 486). Reductions in absolute MSC scores were significantly greater with the combination than placebo at all subsequent time points (p < 0.01). The combination resulted in significantly greater reductions compared with placebo for percent MSC, absolute TSC, and percent TSC scores at 60 minutes postdose (all p < 0.05) and throughout the study (all p < 0.05). The incidence of adverse events was 1.6 and 3.3% for the combination and placebo, respectively. In conclusion, fexofenadine HCl 60 mg/pseudoephedrine HCl 120 mg is effective in the treatment of patients with moderate-to-severe seasonal AR, with an onset of action of 60 minutes and a good safety profile.
