當越來越多的藥物被發展出來進而治療人類的疾病，人們使用藥物時只知道該藥物對疾病的療效，卻忽略了其中可能隱藏的危機，不只是西藥，連中藥也隱藏相當大的危機。雖然國內有藥品管制局進行藥物交互作用的控管，但是藥物交互作用真的被有效控管嗎？成效又如何呢？有鑑於此，這成為大家都想知道的問題。 利用健保資料庫中龐大的門診資料，嘗試推估國人藥物交互作用的情形，由國人十大死因中得知，其中尤以慢性病病患的情形更為嚴重，例如：惡性腫瘤、腦血管疾病、心臟疾病、糖尿病、肝病和高血壓，本次研究以心血管病患為討論主體，試瞭解在長期服用心血管藥物時，醫生在已知病患病情之下卻無法避免藥物交互作用的情形為何，利用資料採礦的方法，找出可能造成交互作用發生的原因、族群，進而去提醒醫療機構避免其發生。 研究發現，心血管疾病病患分為一些併發症族群，如：心臟病、心血管疾病糖尿病、關節炎、消化潰瘍，從這些病患用藥中發現許多交互作用的用藥與其併發症也許多相關。高血壓疾病病患大多以強心劑、利尿劑為主的交互作用，心血管疾病併發糖尿病病患大多以口服降血糖為主的交互作用，心血管疾病併發關節炎病患大多以解熱鎮痛劑為主的交互作用，而心血管疾病併發消化潰瘍病患大多以制酸劑為主的交互作用。 健保局應當面對且對交互作用之高危險族群作一共同用藥規則，將用藥危機降到最低，讓心血管病患在治療的過程中，得以享有良好的醫療品質，亦不造成藥物濫用、浪費之情形。 / As more medicines are being developed to cope with diseases, most of the users think of the therapeutic effect of the medicine without thinking of the risk that might have associated with drug interactions. The risk of drug interactions could have set chemical reactions thereby causing drug side effects. Although the National Bureau of Controlled Drugs has set a procedure for controlling drug interactions, the issue of validity and efficiency remains an open question. The trend of people contracting chronic diseases is on the rise, one of which is cardiovascular. The attempt of this paper is to observe for the effect of drug interactions if any for the long term usage of the cardiovascular medications under the supervision of the doctors. We adopt data mining techniques to single out the probable variable causes in triggering negative effect of drug interactions and presented them to related medical personnel so that a tightening measure is adopted when administered the medications. The data used in this research comes from the National Health Insurance Research Database. Our research findings have reviewed that cardiovascular disease patients suffering from the complications, such as diabetes, arthritis, peptic ulcer and hear disease are highly related to the drug interactions. Heart disease patients are at risk of cardiac stimultants and diuretics. Diabetic’s patients taking the Sulfonylureas suffer from its interactions. And arthritis patients are at risk of having the side effects of taking Aspirin. Bureau of National Health Insurance should set a standard procedure in monitoring the prescription given by the medical personnel in an effort to reduce the risk of drug interactions and set off the stage of quality medical treatment to keep off the abuse of drug usages.
