ABSTRACT
With the advent of bezoar substitutes, bezoar compound has been widely used in clinics. Bezoar is commonly applied in the traditional prescriptions for emergency. Due to the complex compositions and difficult soluble constituents, the prescriptions show the disadvantages of low bioavailability and slow onset in clinical application, and the effectiveness is usually related with the adminis-tration route and characteristics of dosage form of the preparations. The exiting bezoar compound and its new dosage forms were summa-rized in the paper, and the existing bezoar compound preparations were stated according to the characteristics of dosage forms and com-pound clinical application in order to promote the development and application of bezoar new dosage forms.
ABSTRACT
OBJECTIVE:To provide reference for rational clinical use of drugs and sound management thereof. METH-ODS:The relative data of antihypertensive drugs applied in 34 hospitals in Wuhan city during 2011 and 2013 were analyzed sta-tistically by using the analytical method of the Defined Daily Dose(DDD)recommended by WHO. RESULTS:Both consump-tion amount and DDDs of antihypertensive drugs in Wuhan city were increasing during 2011 and 2013,where calcium-channel blockers(CCB)enjoyed the largest consumption amount and the highest DDDs,with the constituent ratio of over 40% respec-tively,followed by angiotensinⅡreceptor antagonist (ARB) and angiotensin converting enzyme inhibitors (ACEIs). The con-sumption amount and DDDs of new compound preparation also increased. Top three single drugs in terms of consumption amount were amlodipine,levamlodipine and valsartan,while amlodipine,nifedipine and felodipine ranked the top three in DDDs list. CONCLUSIONS:Wide usage of antihypertensive drugs in Wuhan City are respectively CCB,ARB,ACEI,adrener-gic receptor blockers and diuretics,which are applied in current principle of antihypertensive drugs use and basically rational in clinical application.
ABSTRACT
Objective To investigate the compatible stability of alanylglutamine by using continuous series infusion device,and provide experimental evidence for reasonable clinical use of alanylglutamine. Methods pH,osmolality and quantity of insoluble particles were measured by using pH meter, automatic freezing osmometer and intelligent particle detector respectively.A HPLC method was built for the determination of the content of alanylglutamine. Results pH and quantity of insoluble particles of the two tested groups did not change significantly over time. Osmolality and the content of alanylglutamine fluctuated greatly in the first half an hour. Conclusion Continuous series infusion device may not mix each bottle of solution very well.It is suggested to premix these solutions to ensure the stability of the dilution ratio and the osmotic pressure of the mixture in the process of the infusion.
ABSTRACT
Objective To explore the influence of different administration time on antidepressant effect of seven clinical common antidepressants. Methods Male mice were randomly divided into eight groups:venlafaxine (75 mg/kg), sertraline (20 mg/kg), fluoxetine (20 mg/kg), doxepin (15 mg/kg), mirtazapine (15 mg/kg), citalopram (40 mg/kg), trazodo?ne (50 mg/kg) and control (saline) groups. Each group contained 36 mice. Drugs were administered to 6 mice per group 30 min before forced swimming test at the 6 time points (9:00, 13:00 and 17:00 as light phase and 21:00, 1:00 and 5:00 as dark phase). Forced swimming test was applied to determine the influence of dosing time on anti-immobility effect of seven antidepressants at each time point. Results Immobility time in venlafaxine group and sertraline group significant?ly decreased compared with that of control group at all time points(all P<0.05). Moreover, anti-immobility effects of ven?lafaxine, fluoxetine, mirtazapine and doxepin were better during the dark phase than during the light phase (all P<0.05). In addition, immobility time in sertraline group decreased at the late part of dark phase (5:00) and the early part of light phase (9:00) compared with other phases (P<0.05). Conclusions Most antidepressants show 24-h rhythm dependent an?ti-immobility effects, but rhythmic patterns are not completely consistent among different antidepressants. Further study is needed to explore the chronopharmacological mechanism and clinical applications of these antidepressants.
ABSTRACT
Objective:To explore the pharmaceutical care points in advanced lung cancer patients with brain metastases. Meth-ods:Clinical pharmacists participated in the drug treatment process of one case of small cell cancer patient with brain metastases. Pharmaceutical care was carried out from various aspects, including brain metastases treatment, chemotherapy, antiviral therapy and patient education. Results:Cerebral transfer symptoms and quality of life of the patient were effectively improved and adverse reactions were reduced by the pharmaceutical care. Conclusion:By the implementation of pharmaceutical care on the patient, clinical pharma-cists can not only improve their own knowledge base and exploit professional advantage, but also provide suggestions on rational drug use for health care professionals.
