ABSTRACT

OBJECTIVE: To investigate the efficacy and safety of nebulized inhalation of terbutaline sulfate for injection in the treatment of children with wheezing disease. METHODS: From December 2016 to April 2018,440 cases of lower respiratory tract infection with cough and wheezing were hospitalized for treatment in the Department of Respiratory Medicine of Children's Hospital of Soochow University,Chengdu Women's & Children's Central Hospital and Dalian Children's Hospital of Dalian Medical University. The children were selected and randomly divided into terbutaline sulfate for injection group(Group A),terbutaline sulphate solution for nebulization group(Group B)and control group(Group C). The efficacy and adverse reactions of the three groups were compared. RESULTS: The scores of wheezing symptoms in group A and group B decreased more significantly than those in group C(P<0.05). Group A and group B had a certain influence on heart rate,and the heart rate at 30 minutes and 60 minutes after nebulization was higher than that of group C. In addition to the effect on heart rate,no other adverse reactions were found in group A and group C;one patient in the group B developed arm tremor and disappeared after stopping the drug. CONCLUSION: Inhalation of terbutaline sulfate for injection in the treatment of children with wheezing disease can shorten the treatment time and effectively improve the clinical treatment effect. The clinical efficacy is comparable to that of terbutaline sulphate solution for nebulization,and it is safe and worthy of clinical application.

ABSTRACT

OBJECTIVE: To establish a qualitative and quantitative HPLC method for the determination of impurity Iin tebutaline sulfate. METHODS: The Kromasil C18 column(4.6 mm×150 mm,5 μm) was used as the analysis column;buffer solution [dissolving 4.23 g of sodium hexanesulfonate in 770 mL of 0.050 mol·L-1 ammonium formate solution (pH 3)]-methanol (77:23) was used as the mobile phase. The flow rate was 1.0 mL·min-1, the column temperature was maitained at 30℃, the detection wavelength was set at 276 nm,and the injectiong volume was 20 μL. Area normalization method with correction factor was used for the quantitative analysis of the impurity I. RESULTS: Under the separation condition, the impurity I was completely separated from the principal components. The calibration curve showed good linearity in the concentration range of 0.10-579 μg·mL-1(r=1.000 0). The correction factor was 3.6. CONCLUSION: The area normalization method with correction factor developed in the paper can be used for the qualitative and quantitative analysis of the impurity Iin terbutaline sulfate, which can not only solve the problem of the availability of impurity reference standards, but also reflect the actual contents of impurity. The method provides an efficient and convenient method for quality control of terbutaline sulfate.

ABSTRACT

Objectives To investigate the effect and mechanism of terbutaline sulfate on pulmonary fluid transport in pre-mature rats. Methods Pregnant rats were randomly divided into 5 groups (control group, premature group, low-dose terbutaline group, high-dose terbutaline group and dexamethasone group). Drugs were administered by gavage after rats were fertilized for 16 days and continued for 3 days. Premature rats were taken out from the 19 days pregnant rats, and mature rats were delivered on the due day. Lungs were collected, and the ratio of pulmonary wet weight to dry weight (W/D), Na+, K+-ATP ase activity and concentration of cyclic adenosine monophosphate (cAMP) were measured in lungs. Results The W/D rate, Na+,K+-ATPase acti-vity and cAMP concentration in lungs had significant difference among different groups (P<0.01). The W/D rate was highest in premature group and lowest in the control group. It was lower in the high-dose terbutaline group than in the low-dose terbutaline group and the dexamethasone group (P<0.05). The Na+,K+-ATPase activity was lowest in premature group and highest in high-dose terbutaline group. It was higher in dexamethasone group, low-dose terbutaline group, and high-dose terbutaline group than in premature group, and it was higher in high-dsoe terbutaline group than in low-dose terbutaline group and dexamethasone group (P<0.05). The cAMP levle was lowest in premature group and highest in high-dose terbutaline group. It was higher in dexamethasone group, low-dose terbutaline group, high-dose terbutaline group than in premature group, and it was higher in high-dose terbutaline group than in low-dose terbutaline group and dexamethasone group (P<0.05). Conclusions Terbutaline sulfate facilitates lung fluid transport in premature rats, leading to reduce the W/D rate in terbutaline-treated group. We speculate that this effect is related to the increased cAMP level and Na+, K+-ATPase activity in lung tissue.

ABSTRACT

A high performance liquid chromatographic method with hypersil C_(18) column, 0.020 mol/L potassium dihydrogen phosphate solution(which contains 0.25% triethylamine, pH 5.1)-methanol(20∶ 80, V/V) as mobile phase and fluorescence detection with 280 nm as excitation wavelength and 320 nm as emission wavelength has been developed for the determination of terbutaline sulfate and propranolol hydrochloride in Erythrocyte suspensions. Erythrocyte surface receptor oscillating reacted 1 h with terbutaline in 37 ℃ water bath. Free terbutaline and propranolol were separated from the membrane receptor-binding complex through 1500 r/min centrifugal in 5 min. The linear range was 0.010-3.000 mg/L in Alsever's solutions and the correlation coefficients were 0.9999 and 0.9998. The relative standard deviations(RSDs) of terbutaline and propranolol were 0.8% and 1.2%, respectively. The limits of detection(LODs) of both were 1.00 and 3.00 mg/L. This simple, safety and sensitive method was suitable for the determination of terbutaline and propranolol in erythrocyte suspensions and for the study of receptor-ligand binding.

ABSTRACT

It was found that Ag nanoparticles (NPs) could enhance the chemiluminescence (CL) intensity of luminol- potassium ferricyanide system. On the basis of enhancement effect,a flow injection method was developed for the determination of terbutaline sulfate. The structure and shape of Ag NPs were characterized by transmission electron microscopy. The UV-Vis absorption spectra and chemiluminescence spectra suggested that new luminophor was not formed after Ag NPs introducing in luminol-potassium ferricyanide chemiluminescence system. A possible mechanism of Ag NPs strengthening on luminol-potassium ferricyanide CL reaction was also discussed. The effect of concentration of luminol,potassium ferricyanide,sodium hydroxide and Ag NPs on CL reaction was investigated respectively. In the optimum conditions,the linear range was 1.0×10~(-9) -2.0 ×10~(-5) g/L(r =0.9935) and the detection limit was 1×10~(-10) g/L. The relative standard deviation (RSD) was 3.6% for 1. 0 ×10~(-6) g/L terbutaline sulfate (n = 11 ). The recommended method has been successfully applied to the determination of terbutaline sulfate tablets and the recovery was between 98. 5% - 102. 5% ,moreover the results were almost identical with the same results of Pharmacopoeia method.
