The analytes and their deuterated analogs were quantitatively extracted from100 μL human plasma by solid phase extraction on Oasis HLB cartridges. The chromatographic separation of the analytes was achieved on a Chromolith RP18 e(100 mm × 4.6 mm) analytical column within 2.5 min. The resolution factor between AML and VAL, AML and HCTZ, and VAL and HCTZ was 2.9, 1.5 and 1.4, respectively,under isocratic conditions. The method was validated over a dynamic concentration range of 0.02–20.0 ng/m L for AML, 5.00–10,000 ng/m L for VAL and 0.20–200 ng/m L for HCTZ. Ion-suppression/enhancement effects were investigated by post-column infusion technique. The mean IS-normalized matrix factors for AML, VAL and HCTZ were 0.992, 0.994 and 0.998, respectively. The intra-batch and inter-batch precision(% CV) across quality control levels was ≤ 5.56% and the recovery was in the range of 93.4%–99.6% for all the analytes. The method was successfully applied to a bioequivalence study of 5 mg AML + 160 mg VAL + 12.5 mg HCTZ tablet formulation(test and reference) in 18 healthy Indian males under fasting. The mean log-transformed ratios of C max, AUC0–120 h and AUC0-inf and their 90% CIs were within 90.2%–102.1%. The assay reproducibility was demonstrated by reanalysis of 90 incurred samples.展开更多

Satisfactory resolution was achieved using a RP-C18 chromatographic column, Phenomenex Kinetex (150 mm × 4.6 mm i.d) and a mobile phase consisting of acetonitrile-phosphate buffer (0.05 M) with pH 2.8 in the proportion of (40/60, v/v) at a flow rate 0.8 mL/min and the wavelength detection was 227 nm. The retention time for HCT, AML and VAls was 2.26, 3.16 and 11.19 min;respectively. The described method was linear over a range of 4-28 μg /ml, 5-40 μg /ml and 1-12 μg /ml for AML, Vals and HCT;respectively. The mean percent recoveries were 99.94%, 99.96% and 99.78% for AML, Vals and HCT;respectively. F-test and t-test at 95%con?dence level were used to check the intermediate precision data obtained under different experimental setups. The method could be used for analysis of combined dose tablet formulation containing AML, Vals, HCT as well as spiked human plasma.展开更多

Methods: A total of 106 patients with chronic heart failure comorbid anxiety and depression from February 2020 to March 2022 were continuously enrolled and divided into control group (36 cases), observation group A (36 cases) and observation group B (34 cases) according to treatment methods. All groups were given conventional treatment. On the basis of routine treatment, the control group, observation group A and observation group B were given valsartan, sacubitril-valsartan and sacubitril-valsartan plus Zhenyuan Capsules for the treatment of consecutive 8 weeks. The patients in the 3 groups were evaluated by the Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) before and after treatment, and the clinical efficacy of heart failure was evaluated, and the detection of left ventricular ejection fraction (LVEF), left ventricular end systolic diameter (LVESD), left ventricular end-diastolic diameter (LVEDD), N terminal brain natriuretic peptide (NT-proBNP), tumor necrosis factor alpha (TNF alpha), interleukin 6 (IL-6), c-reactive protein (CRP) was conducted. Results: The clinical efficacy rate and total effective rate of heart failure in observation group A and observation group B were significantly higher than those in the control group (P < 0.05), and the observation group B was higher than the observation group A (P < 0.05);SAS and SDS scores in observation group A and observation group B were significantly lower than the control group (P < 0.05), and observation group B was lower than observation group A (P < 0.05);The LVEF in the three groups was all increased compared with those before treatment, and the levels of LVESD, LVEDD, NT-proBNP, TNF-α, IL-6, and hs-CRP were all decreased compared with those before treatment;The changes of above indexes in observation group A and observation group B were more significant than those in control group (P < 0.05). Except for the LVEDD index, the observation group B had significant changes compared with the observation group A (P < 0.05). Conclusion: Sacubitril valsartan can improve cardiac function, reduce inflammatory response, and improve anxiety and depression in patients with chronic heart failure, and the treatment effect of combination with Zhenyuan Capsule is more significant.展开更多
