RESUMO
Much of the damage to health caused by drugs could be prevented by appropriate care. A well-defined duty of care and further information are required for healthcare professionals. Although there are many litigation cases to use as references, neither the extent of the duty of care nor the obligation to explain medication according to the type of drug prescribed has yet been fully established. Thus, we systematically collected decided cases of adverse drug events, and assessed the degree of the duties of care and information. Specifically, we collected decided cases in which physicians, dentists, pharmacists, nurses, or hospitals had been sued. Data were derived from Bessatsu Jurist Iryo-kago Hanrei Hyakusen, Hanrei Jihou, and Hanrei Times from 1989 to November 2013, and information on precedents in the records of the Supreme Court of Japan from 2001 to November 2013. We analyzed the cases, and assessed the following according to the type of drug: (1) standards and explanations when dealing with drugs that were critical issues in litigation, and (2) the degree of the physician's or pharmacist's duties of care and information. In total, 126 cases were collected. The number of drug categories classified was 27, and 9 were considered of practical importance. After this systematic review, we found a trend in the degree of the required level of care and information on several drugs. With respect to duties of care and information, the gap between the required level and actual practice suggests that healthcare professionals must improve their care and explanations.

Statins have pleiotropic vascular protective effects that are independent of their cholesterol-lowering effects. The aim of the present study was to determine if statins have anti-flushing actions in an animal model of forced exercise-induced temperature dysregulation in menopausal hot flushes, and to clarify the critical role of statins in regulating vascular reactivity in the tail arteries of ovariectomized rats. Administration of fluvastatin or pravastatin (3mg/kg/day for 7days, p.o.) significantly ameliorated the flushing of tail skin in ovariectomized mice, and the effect of each statin was comparable with that of estrogen replacement (1mg/kg/week for 3weeks, i.m.). In phenylephrine-pre-contracted rat-tail arteries, ovariectomy inhibited acetylcholine-induced relaxation, but augmented sodium nitroprusside-induced relaxation. These ovariectomy-altered vasodilator responses were restored by fluvastatin treatment as well as by estrogen replacement. Nitrite/nitrate levels in the plasma of ovariectomized animals showed significantly lower values than those in sham-operated animals; this ovariectomy-reduced production of nitric oxide was improved by fluvastatin treatment. These data provide the first experimental evidence that statins such as fluvastatin and pravastatin exert anti-flushing effects by improving vasomotor dysfunction through nitric oxide-mediated mechanisms in ovariectomized animals. Thus, therapeutic methods that target improvement of vasomotor dysfunction could be novel strategies for reducing menopausal hot flushes.
