It is intended to provide a drug which is efficacious in treating and preventing diseases wherein ischemia or an inflammatory substance associated with ischemia participates in the onset or worsening thereof. Because of containing as the active ingredient a substance selected from among farnesol, a farnesol derivative, a tocopherol derivative, a tocotrienol derivative, pharmacologically acceptable salts thereof and solvates thereof, the above-described inhibitor of ischemic disorders can exert therapeutic and preventive effects on diseases wherein ischemia or an inflammatory substance associated with ischemia participates in the onset or worsening thereof (for example, brain infarction, brain edema, cardiac infarction, etc.) not only by the administration in the acute ischemic stage but also by the therapeutic administration in subacute and/or chronic stages after ischemia-reperfusion. It is also intended to provide a farnesol carboxylic acid ester derivative and a method of producing the same.
