To get information about the status of use of oral hypoglycaemic agents in an inland and coastal hospitals,the ordes of total cost and DDDs were employed to compare the use of oral hypoglycaemic agents in an inland hospital and a coastal hospital.Our results showed that the much less biguanides were used in the coastal hospital as compared with the inland hospital.It is conclinical practice included dimethyl biguanide,glipizide,gliclazide and glibenclamide.

To find out the patterns and trend of clinical use of antihypertensive agents to provide a guidance for rational use of drugs, the antihypertensive drugs used in our hospital during 1995-1999 period was investigated in respect to the sum of consumption cost, drugs used and DDDs. Our results showed that the DDDs and the consumption cost for antihypertensive drugs have increased gradually for recent 5 years. The order of DDDs of drugs was as follows: calcium antagonists, adrenergic blocking drugs, ACE inhibitors, the drugs affecting sympathetic transmitters and peripheral vasodilators. The order of sum of money was as follows: ACE inhibitors, calcium antagonists and calcium antagonists respectively. It is concluded that a diverse array of anthhypertensive agents were available and widely used clinically and attention should be paid to the rational use of the drugs.

To study the status and patterns of the drug utilization in the diseases of lower respiratory tract, the drug utilization for 290 inpatients with respiratory tract diseases in a Shanghai hospital druing 1993-1997 was analyzed by using Acute Physiology, Age, Chronic Health Evaluation(APACHE) and index of defined daily dose numbers(DDDs). The relativity between APACHE and DDDs was studied. It was found that most common drugs was anti-infection agents and expectorants, accounting for 39.06% and 38.38 %, respectively. The quantitative relationship between drug consumption and disease severity was not observed. It is concluded that the status of the drug utilization can't be demonstrated by analyzing the frequency of drug use by using DDDs.

To better understand the drugs, frequency and other factors involved in the drug-induced renal failure, 227 cases of renal failure reported in the Chinese medical and pharmaceutical journals were statistically analyzed. Our results showed that the drugs that tend to cause renal failure are antibiotics, involving 80 cases, followed by antituberculosis agents(38 eases)and dehydration agents. Gentamycin (47 cases) and rifrimactane(36 cases) were among the drugs with highest incidence. There were 58 cases of death due to drug-related renal failure.

To investigate the efficacy and safety of losartan in the treatment of essential hypertension, 81 patients were randomly assigned to two groups. Patients in the first group(n =41) were given losartan 50 mg to 100 mg once a day; those in the second group( n = 40) were given benazepril 10 mg to 20 mg once a day. The treatment course lasted for a weeks. Ambulatory blood pressure, hepatic and renal functions, blood glucose were examined before and after therapy. Our results showed that the total efficacy rate in losartan group was 93％ while that in benazepril group was 90％. The efficacy was similar between the two groups. However, effect of 24 h blood pressure control by lossrtan was superior to than of benazepril. The adverse reaction of losartan was milder that that of benazepril. It is concluded that losartan is a safe, long-acting antihypertensive agent for mild and moderate hypertension with good patient tolerance and less adverse reactions.

To investigate the efficacy and adverse effects of venlafaxine in the treatment of depression, patients were given venlafaxine or amitriptyline for 6 weeks. The efficacy of the drugs were assessed by using HAMD and HAMA at the 4th, 7th, 14th and 42nd day before and after the medication. The adverse effects were evaluated by TESS. Our results showed that the effect time of venlafaxine was (8.52±4.47) d, which was fasler the that of amitriptyline. The effective rate of venlafaxine was 83%, which was faster the that of amitriptyline. but venlafaxine caused less dry mouth, constipation, blurred vusion, tachycardia and anorexia etc. It is concluded that venlafaxine worked faster with less side effect in the treatment of depression as compared with amitriptyline.

To help pharmaceutical companies absorb lessons from the Ban on PPA, the article analyses the behavior of SinoUS Smith Kline & French, which led to great loss after the Ban of an PPA by SDA of China. It points out that the Ban of PPA did not come unexpectedly. Before the Ban many clinical reports had been released and the authorities of some countries had already introduced ban on PPA or issued warnings on the possible danger of PPA. If the company in question had taken timely measures to keep track of the information, the loss could have been minimized, It is concluded that the pharmaceutical companies should step up their effort for the monitoring and following-up of their products after introduction of their durgs to markets and attach importance to the study of pharmacoepidemioloy. Pharmaceutical companies should put emphasis on the collection of information.

Objective:To investigate the use of antibacterial in our hospital in 2004-2006 and analyze its features and tendency so as to provide references for the rational use.Method:The stocked data of antibacterial from 2004-2006 were collected by the computer management system.The DDDs of antibacterial in our hospital were classified and analyzed according to the defined daily dose(DDD).Result:The ratio of the antibacterial costs in the annual drug consumption sum was decreased year by year.The average ratio was 17.01%in three years,lower than the 27.97%,which was the average of total hospitals in China.The DDDs of quinolones in our hospital had been dominating the first place in 2004～2006,and the average increase was 14.1%in three years.The second was cephalosporins with 13.61%of its average increase,similar to quinolones,but its consumption sum was more than that of quinolones.Conclusion:The use of antibacterial in our hospital in 2004-2006 was rational on the whole.

Objective:To analyze the clinical drug consultation to summarize the characteristics of drug consulting services and improve clinical pharmacy service quality.Method:756 complete cases of clinical drug consulting materials were analyzed and summarized in our hospital emergency in the past three years.Result:The major consulters were patients, accounting for 59.92 percent.The most often consulted anti-infective drugs accounted for 35.85 percent.The primary attention was given to usage and dosage of drugs,accounting for 12.96 percent.Conclusion:The drug consultation lets us fully understand the issues most concerned about by medical personnel and patients,makes pharmacists improve their professional level and makes sure that patients are given reasonable,safe and effective medication.

Objective:To study the reasons and preventive measure of the effect of human urinary kallikrein on blood pressure in the treatment of acute cerebral infarction.Method:Documents about the effect of human urinary kallikrein on blood pressure of pre-clinical study and the phaseⅠ-Ⅲclinical trials were collected and analyzed in combination with the related information of the phaseⅣclinical trial from our hospital.Result:The rate and concentration of medication in combination with ACEI were the reasons for the effect of human urinary kallikrein on blood pressure.Conclusion:Controlling the rate and concentration of medication and forbidding the combined use of ACEI from the 72hr before the medication and the 24hr after it can prevent hypotension caused by human urinary kallikrein.
