<b>4．Evaluation of the Risk Minimization Plan of the Drugs such as Thalidomide </b> / 薬剤疫学

<p>If mother use drugs during pregnancy, the risk to the fetus is concerned. So the management of the drug is important. Previously, we have experienced The Thalidomide Disaster, the drug has not been used for many years since then.

In the patients who use thalidomide, there are few women with the possibility of pregnancy. And by strict management, it has been concerned about the problem of the things that is difficult to use in patients not related to pregnancy. Isotretinoin is currently being used in the United States as the drug for acne therapy. Although there is no adaptation in Japan, the physician personally import the drug and administer to the patients.

Because the drug is not marketed in Japan, the offer of the information is not enough. Valproic acid has both adaptation the prevention of the migraine headache other than epilepsy. The control of epilepsy is very important, there are patients that use the drug after consideration of risk benefit balance. On the other hand, benefit was relatively small when use it for the prevention of the migraine headache. FDA prohibited the use during pregnancy for this purpose. In Japan, it is the same regulation regardless of adaptation, and balance of the risk benefit is not clear. It was thought that different attention awakening should be carried out by adaptation in future.</p><p></p>

Intake rate of folic acid among pregnant women consulting the Japan Drug Information Institute in Pregnancy / 医薬品情報学

<b>Objective: </b>In 2000, the Ministry of Health and Welfare issued an advisory that recommended intake of 0.4mg of folic acid in dietary supplements to reduce the risk of development of neural tube defects.  Since subsequent reports of questionnaire surveys by various investigators showed a low in the intake rate, we surveyed and evaluated the folic acid intake rate among the pregnant women consulting the Japan Drug Information Institute in Pregnancy.<br><b>Methods: </b>We evaluated differences in folic acid intake rate according to the consulting women’s background factors. i.e., age, pregnancy planning, pregnancy history, and taking of anticonvulsant drugs in the 1053 women capable of participating in the survey among the 1061 pregnant women who requested a consultation with the Japan Drug Information Institute in Pregnancy between April 2006 and August 2008.<br><b>Results: </b>According to the result of our survey, the intake rate of folic acid was 29% of the 1053 pregnant women.  The only 3 women of the 42 pregnant women taking anticonvulsant drugs took folic acid before they got pregnant.<br><b>Conclusion: </b>Even now, 8 years after the Ministry of Health and Welfare advisory, the folic acid intake rate is low.  Drawing upon successful measures promoting intake in the U.S. and Canada,we play a vital role in delivering this critical health information to pregnant women.
