Definitions
- Cholesterol is a major building block of all plasma membranes and a key compound for the synthesis of steroid hormones and bile salts. Cholesterol and triglycerides are lipophilic and cannot dissolve in water and thus cannot travel through the bloodstream in their unaltered forms. They are made water-soluble by combining with proteins produced by the liver and intestine called apolipoproteins and the complexes thus formed are called lipoproteins, which vary in size, weight and density. Two of the major classes are called low-density lipoproteins (LDLs) and high density lipoproteins (HDLs). LDL contains 60 to 70 percent of serum cholesterol and is believed to pick up cholesterol and deposit it in body cells, including smooth muscle cells in arteries.
- LDLs low-density lipoproteins
- HDLs high density lipoproteins
- HDL which contains 20 to 30 percent of total serum cholesterol
- VLDL very low density lipoprotein
- MEVACOR® lovastatin
- ZOCOR® simvastatin
- PRAVACHOL® pravastatin
- LESCOL® fluvastatin
- lipid-lowering drugs including niacin (nicotinic acid), fibrates such as gemfibrozil, and inhibitors of HMG-CoA reductase, such as lovastatin and simvastatin.
- niacin nicotinic acid
- fibrates such as gemfibrozil
- HMG-CoA reductase such as lovastatin and simvastatin.
- HMG-CoA reductase such as lovastatin and simvastatin.
- the fibrates have the side effects of gastrointestinal disturbances and an increased risk of gallstones.
- HMG-CoA reductase inhibitors are relatively safe and well- tolerated, their effect on HDL-cholesterol is small, usually about less than 10%, even at maximum dose.
- the compounds employed in the present invention are 5cc- reductase inhibitors.
- Finasteride PROSCAR®
- PROSCAR® is a commercially available 5 -reductase inhibitor
- BPH benign prostatic hype ⁇ lasia
- Inhibition of 5 -reductase is extremely well-tolerated, probably because the only known function of the enzyme in adults is to support certain male secondary sexual characteristics, including prostate growth.
- Males who are homozygous for 5 ⁇ -reductase deficiency have small prostates and do not develop BPH.
- Women who are homozygous for 5 -reductase deficiency are phenotypically normal, indicating that the enzyme serves no general biological pu ⁇ ose.
- Finasteride the first member of this class to be available for prescription, is a very well- tolerated drug. It is well known that the concentration of HDL cholesterol is lower in men than in women.
- 5 -reductase inhibitors increases serum HDL cholesterol levels.
