The method involved extracting drug with organic solvent under basic conditions. The samples were seperated by ODS column and determined by mass detector. The calibration curve of loratadine was linear within the range of 0.4~100 ng·mL -1 with r=0.9995 . The recovery of this method was within 95%~104%, within day and between day RSD were less than 12%. To study the pharmacokinetics and relative bioavailability of loratadine tablets, two formulations of loratadine tablets were given to 18 healthy male volunteers according to a randomized 2 way cross over design. The C max , AUC 0 t and T max values of the two formulations were 51.89±20.18 ng·mL -1 and 52.48±22.35 ng·mL -1 ; 140.75±88.42 ng·h·mL -1 and 147.24±92.33 ng·h·mL -1 ; 0.81±0.35 h and 0.81±0.27 h respectively. Results from statistic analysis showed that there were no significant difference between the C max , AUC 0-t and T max values of the two formulations. The relative bioavailability of tablets I with respect to tablets II was 97%±13% from the AUC 0 t measurement. Bioequivalance was observed between the two tablets.展开更多

Serum levels of inflammatory factors, Th17/Treg cellular immunity indexes before and after treatment were compared among four groups of patients.Results: Before treatment, differences in serum levels of inflammatory factors and Th17/Treg cellular immunity indexes were not statistically significant among four groups of patients. After treatment, serum HMGB1, IL-8, IL-14, IL-23 and IL-33 levels in combined treatment group were lower than those in montelukast group, loratadine group and tanshinone group;serum IL-17 level was lower than that in montelukast group, loratadine group and tanshinone group while IL-10 and TGF-β levels were higher than those in montelukast group, loratadine group and tanshinone group.Conclusions: Montelukast, loratadine and tanshinone combination therapy for Henoch-Schonlein purpura helps to reduce systemic inflammatory response and balance Th17/Treg cell immunity.展开更多

Methods: fifty-two patients with chronic urticaria were enrolled from January 2020 to April 2021 and randomly divided into control group (n = 26) and study group (n = 26). Treatment: control group: levcetirizine, study group: loratadine. Efficacy, symptom change after treatment and serum inflammatory factors were used as observation indexes to evaluate the drug effect. Results: statistical comparison of curative effect results: there was significant statistical difference between groups (that is, the effective rate of therapeutic effect in the study group was greater than that in the control group), P < 0.05. Statistical comparison results of symptom changes after treatment: after 1 and 2 weeks of treatment, both groups decreased, and there was a significant statistical difference between the groups (that is, the decrease degree in the study group was significantly greater than that in the control group), P < 0.05. Statistical comparison results of serum inflammatory factors: there was little statistical difference between groups before treatment, P > 0.05;All groups decreased after treatment, and there was significant statistical difference between groups (that is, the degree of decrease in the study group was significantly greater than that in the control group), P < 0.05. Conclusion: loratadine is effective in the treatment of chronic urticaria, which is beneficial to accelerate the remission of symptoms and the disappearance of inflammation.展开更多

Methods: Sixty eligible AR kids were randomized into a tuina group and a Western medication group by their visiting sequence, 30 cases in each group. The tuina group was intervened by Liu's infantile tuina therapy, once daily, 5 times as a treatment course, with a 2-day interval after a course; the control group was by orally taking Loratadine. The therapeutic efficacies were compared and analyzed after treatment for 4 successive weeks. Results: After treatment, the symptoms such as itchy nose, sneezing, runny nose, and stuffy nose were significantly improved in both groups (P〈0.05), and the improvements in the tuina group were more remarkable than those in the Western medication group (P〈0.05). The total effective rate was 90.0% in the tuina group versus 73.3% in the Western medication group, and the difference was statistically significant (P〈0.05). Conclusion: Liu's infantile tuina therapy can produce a better therapeutic efficacy in treating AR kids compared to oral administration of Loratadine.展开更多
