ABSTRACT
AIM: To observe the efficacy and compliance of cetirizine hydrochloride and pranoprofen eye drops on children with vernal keratoconjunctivitis. ● METHODS: A total of 63 children with vernal keratoconjunctivitis, from the outpatient department in our hospital between Jan. 2014 and Dec. 2015, were randomly divided into two groups including experimental group and control group. The cases in experimental group were treated with cetirizine hydrochloride, 2 times/d, 5 drops (0. 25ml, 2. 5mg) each time (≤6 years) or 10 drops (0. 5ml, 5mg) each time (>6 years), oral or oral with beverage and food, 1g/L pranoprofen eye drops, 4 times/d, 1 drop each time. The cases in control group were only treated with cetirizine hydrochloride, 2 times /d, 5 drops (0. 25ml, 2. 5mg) each time (≤6 years) or 10 drops (0. 5ml, 5mg) each time (>6 years), oral or oral with beverage and food for 14d. All the children were detected the scores of symptom and pathology before and after treatment. Compliance and side effect of the drug were surveyed by questionnaire. ● RESULTS: The scores of symptom, pathology and overall total after treatment were significantly lower than those before treatment in each group ( texperimental, symptom =10. 41, P ● CONCLUSION: Cetirizine hydrochloride and pranoprofen eye drops in combination may offer a safety and effective treatment on children with vernal keratoconjunctivitis and have good compliance.
ABSTRACT
OBJECTIVE:To establish a method for the determination of related substances in Levo-cetirizine hydrochloride chewable tablet. METHODS:RP-HPLC was performed on the column of Venusil XBP-CN with mobile phase of acetonitrile-0.05 mol/L Sodium dihydrogen phosphate solution(pH value adjusted to 3.0 by phosphoric acid)(60∶40,V/V)at a flow rate of 1.0 ml/min, the detection wavelength was 230 nm,column temperature was 25 ℃,and volume injection was 20 μl. RESULTS:Levo-cetirizine hydrochloride chewable tablet showed good separation with related substances;the linear range of levo-cetirizine hydrochloride was 1.2-2.8 μg/ml(r=0.999 9);the quantification limit and detection limit was 1.4 ng/ml and 0.3 ng/ml,respectively;RSDs of preci-sion,stability and reproducibility tests were lower than 1%;recovery was 96.3%-105.0%(RSD=1.7%,n=9);the contents of re-lated substances were no more than 0.17%. CONCLUSIONS:The method is simple,sensitive,reproducible,accurate and reli-able,and can be used for the determination of related substances in Levo-cetirizine hydrochloride chewable tablet.
ABSTRACT
OBJECTIVE:To study the effects of common percutaneous enhancers on transdermal permeability of cetirizine hy-drochloride(CET). METHODS:Using pH 7.4 phosphate buffer as receiving solution,accumulative permeation rate as index,mod-ified Franz diffusion cell was used to investigate the effects of common percutaneous enhancers on transdermal permeability of CET in skin of abdomen isolated from mice,such as azone (0.06%-2.5%),oleic acid (0.5%-10%),1,3-propanediol (0.5%-10%),propanetriol(0.5%-5%). RESULTS:1,3- propanediol had no improvement effect on the permeability of CET. 24 h accu-mulative permeation amount of CET in 0.06% azone,0.5% oleic acid and 1% propanetriol were the highest among same types, being 227.94,85.25 and 215.15 μg/cm2,respectively. CONCLUSIONS:Of four percutaneous enhancers,the transdermal enhanc-ing efficiencies from high to low are azone>glycerol>oleic acid>1,3-propanediol. Azone and glycerol have the conspicuous pene-tration enhancing effects.
ABSTRACT
OBJECTIVE:To evaluate the economic effect of 3 therapeutic regimens in the treatment of skin allergy. METH-ODS:54 patients with skin allergy in our hospital were randomly divided into A,B,C groups. They were given calcium+Vc+Ma-lay bolt chlorpheniramine (Puermin),calcium+Vc+Loratadine tablets (Kairuitan),calcium+Vc+Cetirizine hydrochloride tablets (Xikewei),respectively. Short-term efficacy was observed,and analyzed with the minimum cost analysis. RESULTS:Effective rates of A,B,C groups were 94.44%,88.89% and 94.44%,respectively,there was no statistical significance (P>0.05);the cure rates of 3 groups were 55.56%,38.89% and 83.33%,there was statistical significance(P<0.05). The cost were 169.70 yu-an,195.70 yuan and 180.40 yuan,respectively. The cost of group A was the lowest. CONCLUSIONS:The regimens of A group is economical,but that of group C the best after comprehensive comparison.
ABSTRACT
OBJECTIVE:To improve the accuracy of the Cetirizine hydrochloride syrup pediatric dose for children. METH-ODS:The dosage of Cetirizine hydrochloride syrup for children with chronic urticaria was accurately measured and compared with before and after pharmacists’intervention. RESULTS:The dosage before and after pharmacists’intervention was significantly high-er than prescribed dosage,the dosage after intervention was lower than before intervention,the differences were statistically signifi-cant(P<0.05). CONCLUSIONS:It is commonly existed that the dosage to children is higher than the prescribed dosage. It is sug-gested that doctors should strictly follow the printed label to make a prescription,pharmacists should strengthen the guidance and in-tervention on medication,and pharmaceutical manufacturers can manufacture suitable Cetirizine hydrochloride preparations special-ly for children to improve drug compliance and dosage accuracy.
