Definitions

• the present invention relates to a method for treating peripheral atherosclerotic disease (arteriosclerosis obliterans) employing a cholesterol lowering drug which is an inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase or an inhibitor of squalene synthetase; an angiotensin converting enzyme (ACE) inhibitor or a combination thereof.
• a cholesterol lowering drug which is an inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase or an inhibitor of squalene synthetase; an angiotensin converting enzyme (ACE) inhibitor or a combination thereof.

• captopril significantly reduced serum cholesterol (-18%) and increased HDL (27%) in hypercholeserolemic patients (Costa et al, "Use of captopril to reduce serum lipids in hypertensive patients with hyperlipidemia," Am. J. Hyperten. 1: 2219-2239, 1988). There is no evidence that these therapeutic effects result from inhibition of the cholesterol synthetic pathway. Thus, the therapeutic mechanism for ACE inhibitors is different from that of HMG CoA reductase inhibitors such as pravastatin and lovastatin.
• platelet aggregability is greater in hypertensives than in normotensives . . . platelet abnormalities may be a risk factor in atherosclerosis . . . If captopril possesses an antiplate aggregability effect in addition to its hypotensive effect, it may be very useful for the prevention of atherosclerosis and thrombotic diseases associated with hypertension.”
