Apply association rules to analysis adverse drug reactions of shuxuening injection based on spontaneous reporting system data / 中国中药杂志

This research based on the analysis of spontaneous reporting system (SRS) data which the 9 601 case reports of Shuxuening injection adverse drug reactions (ADR) in national adverse drug reaction monitoring center during 2005-2012. Apply to the association rules to analysis of the relationship between Shuxuening injection's ADR and the characteristics of ADR reports were. We found that ADR commonly combination were "nausea + breath + chills + vomiting", "nausea + chills + vomiting + palpitations", and their confidence level were 100%. The ADR and the case reports information commonly combination were "itching, and glucose and sodium chloride Injection, and generally ADR report, and normal dosage", "palpitation, and glucose and sodium chloride injection, and normal dosage, and new report", "chills, and generally ADR report, and normal dosage, and 0.9% sodium chloride injection", and their confidence level were 100% too. The results showed that patients using Shuxuening injection occurred most of ADRs were systemic damage, skin and its accessories damage, digestive system damage, etc. And most of cases were generally and new reports, and patients with normal dosage. The ADR's occurred had little related with solvent. It is showed that the Shuxuening injection occurred of ADR mainly related to drug composition. So Shuxuening injection used in clinical need to closely observation, and focus on the ADR reaction, and to do a good job of drug risk management.

Spontaneous reporting system data analysis of parenterally administered Shenmai / 中国中药杂志

Spontaneous reporting system (SRS) datais currently an important source of monitoring and finding ADRs signals throughout the world. This method can promptly and effectively discover ADR signals, thus preventing and avoiding ADRs effectively. Parenterally administered Shenmai has the functions of benefiting vital energy, nourishing Yin and generating body fluids, and activating the pulse. Clinically it is used in various diseases including shock, coronary heart disease, viral myocarditis, chronic pulmonary heart disease, and granulocytopenia. The large, national SRS database of ADRs needs effective evaluation methods. We report on the use of Bayesian confidence propagation neural network method (BCPNN) and proportional reporting ration (PRR) with propensity score to control for confounding variables. Early warning signs of an ADR are, a feeling of suffocation (difficulty exhaling), anaphylactoid reactions and flushing. Furthermore, relevant relationships between the different factors is analysed by association rules (AR). It is found that there is a close relationship between past history of ADRs, a family history of ADRs and itching.

The results showed that chills as a possible warning signal. Tip clinical use Shuxuetong injection when, for the elderly, children, liver and kidney dysfunction are more prone to adverse reactions in patients with other special populations, the need to pay attention to the prevention of systemic allergic reactions, in particular the prevention shivering.

Study of analysis 1 390 adverse drug reactions cases of parenterally administered dengzhan xixin based on China's spontaneous response system / 中国中药杂志

Adverse drug reaction (ADR) monitoring of spontaneous reporting system (SRS) data to detect signals, is the main method of pharmacovigilance by China food and drug administration (CFDA). This study conducted a data analysis of 1 390 ADR cases of parenterally administered Dengzhan Xixin based on China SRS data collected between Jan, 2009 and Dec, 2012. The proportional reporting ratio method (PRR) and Bayesian confidence propagation neural network method (BCPNN) were used for data mining analysis. The results showed that 71 cases of serious ADRs accounted for 1 390, 5.11% of cases reported. There were more men than women (613/593), and people over the age of 60 accounted for 64.03%. The most common ADRs were itching, rash, dizziness, chills, and palpitations. With damage to skin and its accessories 55 forming the highest percentage of ADRs. When propensity score method to control for confounding factors, PRR method and BCPNN methods were applied, headache, dizziness, palpitation, and chills were ADRs warning signals. Due to the limitation of the SRS data, the results still need to be combined with other research to form a comprehensive body of safety evidence, and to guide the rational clinical use and reduce risks.

Pharmacovigilance of parenterally administered salvianolate based on analysis of spontaneous reporting system data / 中国中药杂志

Spontaneous reporting system (SRS) is currently a basic method to monitor and find adverse drug reactions (ADR) signals used worldwide. This method can promptly and effectively discover ADR signals and is of great significance to effectively prevent and avoid ADRs. Parenterally administered salvianolate has the functions of activating blood circulation and removing stasis. It is mainly used in the treatment of stable angina pectoris. As the drug is widely used clinically and ADRs are increasingly reported promptly, ADR information in the national ADR monitoring center's SRS database has also increased. How to quickly and effectively identify suspicious ADRs is a major concern. This study uses BCPNN and PRR to detect early warning signals. S739 ADR case reports were identified. There were 106 types, 1 310 events, and 24 serious ADR cases ( 3.25% of 739 case reports) There wre no deaths. The ten most frequent ADRs were: rash, dizziness, itch, headache, chills and breath, nausea, palpitation, anaphylactic reaction and hot. The drugs early warning signs were dizziness, headache, nausea, itchiness and rash estimated using PRR. Early warning signs based on BCPNN were dizziness and headache. The ADRs of dizziness and headache are early warning signals associated with the nervous system.

Research on early warning signals of adverse drug reactions to parenterally administered xiyanping based on spontaneous reporting system (SRS) data / 中国中药杂志

This article focused on early warning signals regarding the safety of parenterally administered Xiyanping. The study data was obtained from reports made between 2005-2012 from the national spontaneous reporting system (SRS). Proportion reporting ratio (PRR) and Bayesian confidence propagation neural network (BCPNN) algorithms were used to analyse: erythra, pruritus, anaphylactoid reactions and shiver with cold, these 4 adverse drug reactions had a total count of more than 500 events. The article found that Xiyanping's incidence rate of erythra was higher than for background-drugs in every year and in every season. Pruritus was an early warning signal in the second season of 2009, and anaphylactoid reaction was an early warning signal in the fourth season of 2011 and in the second season of 2012. There was however no early warning signal indicated by shiver with cold. This data indicates that erythra maybe an adverse drug reactions to parenterally administered Xiyanping, and if the incidence rate of pruritus and anaphylactoid reaction rises attention should be paid to its safety.

Analysis of adverse reactions and pharmacovigilance research to parenterally administered shuxuening / 中国中药杂志

Parenterally administered Shuxuening is a commonly used Chinese medicine. There is a need to understand the characteristics of adverse drug reactions (ADRs) to it. 9 601 ADR cases reports were collected from the national adverse drug reaction monitoring center reported between January, 2005 and December, 2012. These included 326 serious ADR cases, accounting for 3.93% of the total. It was found that ADR reports increased annually from 2005, reaching a peak in the third quarter of 2009. The number of ADR cases reports were greatest in the third quarter of each year. ADRs in patients aged 60-74, accounted for 3 348 (34.87%) of all cases. 9 391(97.81%) cases were administered by intravenous infusion. In 8 431 cases, the dosage was in accordance with instructions. 61.61% ADR cases occurred on first administration. The ten most frequent symptoms were, rashes, itching, dizziness, palpitations, chills, allergic reactions, shortness of breath, nausea, phlebitis and vomiting. Systemic damage mainly affected the skin and its accessories damage, or the nervous system damage. Through the use of proportional reporting ratio (PRR) and Bayesian confidence propagation neural network (BCPNN) and propensity score applying generalized boosted models (GBM) to control for 17 confounding factors, analysis of the 10 kinds of ADRs found that for the ADR signals of dizziness, palpitations, phlebitis, and vomiting, BCPNN found that dizziness and phlebitis were early warning signals. This research found that in the 60-89 age group, higher dosages of parenterally administered Shuxuening gave rise to more phlebitis. This study provides important information for parenterally administered Shuxuening research, and guidance for its risk management.
