ABSTRACT
Objective: To analyze the compatibility taboo of polyene phosphatidyl choline injection with several kinds of commonly used clinical drugs.Methods: The medical literatures on the compatibility taboos of polyene phosphatidyl choline injection with several commonly used drugs were retrieved and statistically analyzed.Results: After the compatibility of polyene phosphatidyl choline injection with vitamin C, raceanisodamine injection, doxofylline and sodium chloride injection,ambroxol hydrochloride injection,ondansetron hydrochloride injection and the other commonly used drugs, physical and chemical reactions happened in varying degrees.Conclusion: Polyene phosphatidyl choline injection has compatibility taboos with a variety of commonly used drugs.
ABSTRACT
OBJECTIVE:To discuss the influencing factors of anticoagulation with warfarin in patients who had undergone artificial mechanical heart valve replacement and the relation between dosage regimens and international normalized ratio(INR).METHODS:123 patients who had undergone artificial valve replacement patients were followed-up.The patients were treated with warfarin therapy for anticoagulation after surgery,and given a regular follow-up.Patients' age,gender,and INR value etc were recorded and the adverse events including bleeding,embolism and death were observed.RESULTS:No death case was reported;femoral vein thrombosis occurred in 1 case;gingival bleeding occurred in 11 cases and urinary tract bleeding was noted in 3 case.The incidence of anticoagulation-associated ADR was close to that reported in overseas literature.CONCLUSION:According to INR,individual dose of warfarin should be administered on day 5 after artificial valve replacement.Maintaning INR at 1.5～2.0 can achieve certain anticoagulation efficacy and is relatively safe.
ABSTRACT
OBJECTIVE:To study the clinical characteristics and related of the adverse drug reactions(ADR) induced by carbamazepine,and propose preventive solutions.METHODS: 102 cases of carbamazepine-induced ADR,reported in medical journals of China from January 2001 to December 2005,were collected and analyzed.RESULTS:Skin and its appendages received most impairment from carbamazepine-induced adverse reactions(representing 35.3%),followed by general impairment of the body and impairment of the blood & hematopoietic system.Combined use of drugs is liable to induce adverse reactions,indicated by the fact that 16.7% of the sufferers received treatment by combined use of multiple drugs.Most of the ADR occurred 1h after administration.CONCLUSION:Individual differences of patients and combined use of drugs are among the factors that result in carbamazepine-induced adverse reactions.
ABSTRACT
OBJECTIVE:To analyze the ADRs caused by Chinese prepared medicines.METHODS:638ADRs were col?lected from medical journals of2001～2002in consideration of sex,age,administration route,the time of the occurrence and clinical manifestations.RESULTS:There were638ADR cases involving76kinds of Chinese prepared medicines reported in256articles.Of them,shuanghuanglian injection was the most common preparation(87cases).The commonest clinical manifesta?tions were allergic reactions(157cases),followed with the liver and kidney injury.The ages of patients were mostly above60years,the time of the occurrence was mostly within30minutes after administration and about92%of the patients recovered within24hours.CONCLUSION:The occurrence of ADRs of Chinese prepared medicines is related to the route of administra?tion,dosage form of drug,quality of drug,patient’s age and constitution.
ABSTRACT
OBJECTIVE:To study the pharmacokinetics of L-rhGH and rhGH in mice.METHODS:The concertrations of L-rhGH and rhGH in plasma and liver were measured by radioimmunoassay.RESULTS:After intravenous injection,there were significant differences between L-rhGH and rhGH in pharmacokinetic parameters.The Cmax of L-rhGH in the liver was higher than that of rhGH but the T1/2 of L-rhGH was only 17.9% of T1/2 of rhGH;the Cmax of L-rhGH in plasma was lower than that of rhGH and the T1/2 was shorter.CONCLUSION:L-rhGH reveals the pharmacokinetic characteristics which fits in with the physiology of human body.
