| aromatase inhibitor | Drugs, such as aminoglutethimide, that inhibit aromatase, an enzyme used in the synthesis of oestrogens. (05 Mar 2000) |

| aromatase | <enzyme> An enzyme which converts androgens to oestrogens by desaturating ring a of the steroid. This enzyme complex is located in the endoplasmic reticulum of oestrogen-producing cells including ovaries, placenta, testicular sertoli and leydig cells, adipose, and brain tissues. The enzyme complex has two components, one of which is the cyp19 gene product, the aromatase cytochrome p-450. The other component is NADPH-cytochrome p-450 reductase which transfers reducing equivalents to p-450(arom). Registry number: EC 1.14.13.- (12 Dec 1998) |

| a1-trypsin inhibitor | A glycoprotein that is the major protease inhibitor of human serum, is synthesised in the liver, and is genetically polymorphic due to the presence of over 20 alleles; individuals appropriately homozygous are deficient in a1-trypsin and are predisposed to pulmonary emphysema and juvenile hepatic cirrhosis because of alterations in the amino acid and sialic acid components of the glycoprotein. A1-Antitrypsin also inhibits thrombin. Synonym: a1-trypsin inhibitor, human a1-proteinase inhibitor. (05 Mar 2000) |
| ACE inhibitor | <pharmacology> A group of antihypertensive medications that work by inhibiting an enzyme (angiotensin-converting enzyme) that is important in the regulation of blood pressure. Studies have also indicated that it may help prevent or slow the progression of kidney disease in patients with diabetes. Examples include: captopril, ramipril, enalapril, losartan potassium, bepridil and lisinopril. (12 Mar 1998) |
| aldose reductase inhibitor | <pharmacology> A class of drugs being studied as a way to prevent eye and nerve damage in people with diabetes. Aldose reductase is an enzyme that is normally present in the eye and in many other parts of the body. It helps change glucose (sugar) into a sugar alcohol called sorbitol. Too much sorbitol trapped in eye and nerve cells can damage these cells, leading to retinopathy and neuropathy. Drugs that prevent or slow (inhibit) the action of aldose reductase are being studied as a way to prevent or delay these complications of diabetes. (09 Oct 1997) |
| angiotensin-converting enzyme inhibitor | <pharmacology> A class of drugs used in the treatment of hypertension and heart failure. They exert their haemodynamic effect mainly by inhibiting the renin-angiotensin system and produce a reduction of peripheral arterial resistance. They also modulate sympathetic nervous system activity and increase prostaglandin synthesis. They cause mainly vasodilation and mild natriuresis without affecting heart rate and contractility. (14 Aug 2000) |
| beta-lactamase inhibitor | <pharmacology> Drugs such as clavulanic acid, which are used to inhibit bacterial beta-lactamases; often used with a penicillin or cephalosporin to overcome drug resistance. (05 Mar 2000) |
| Bowman-Birk inhibitor | A polypeptide that will inhibit both trypsin and chymotrypsin. (05 Mar 2000) |
| C1 esterase inhibitor | An a2-neuraminoglycoprotein that inhibits the enzymatic activity of C1 esterase, the activated first component of complement. A deficiency of this inhibitor results in a lack of inhibition of C1r and C1s leading to uncontrolled activation of the complement cascade and oedema. (05 Mar 2000) |
| carbonate dehydratase inhibitor | An agent, usually chemically related to the sulfonamides, that inhibits the activity of carbonate dehydratase, producing a general decrease in the formation of H2CO3 in the tissues. See: acetazolamide, dichlorphenamide. Synonym: carbonic anhydrase inhibitor. (05 Mar 2000) |
| carbonic acid inhibitor | <pharmacology> A group of diuretic medications which act to inhibit the enzyme carbonic anhydrase to create a metabolic acidosis. Many of these medications are used in the treatment of glaucoma. (27 Sep 1997) |
| carbonic anhydrase inhibitor | <pharmacology> A group of medications (sulphonamide drugs) which inhibit the enzyme carbonic anhydrase. These medications are used in the treatment of glaucoma. Examples include acetazolamide, dichlorphenamide and methazolamide. (27 Sep 1997) |
| mammary derived growth inhibitor | Fatty acid binding protein that inhibits proliferation of mammary carcinoma cells. (18 Nov 1997) |
| mechanism-based inhibitor | A competitive inhibitor that is converted to an irreversible inhibitor at the active site of the enzyme. Synonym: mechanism-based inhibitor. (05 Mar 2000) |
| glucosidase inhibitor | Agents such as acarbose which reduce gastrointestinal absorption of carbohydrates. This group of drugs has been known popularly as "starch blockers". They lower plasma glucose levels and tend to cause weight loss. A limiting side effect is flatulence. (05 Mar 2000) |
| medication, ace-inhibitor | Agents that inhibit ACE (angiotensin-converting enzyme), thereby acting as vasodilators (really as anti-vasoconstrictors), lightening the stress load on the heart. (12 Dec 1998) |
Synonyms : Inhibitors, Aromatase
| aromatase inhibitor |
Aromatase inhibitors (AI) are a class of drugs used in the treatment of breast cancer in post-menopausal women. Aromatase inhibitors work by inhibiting the action of the enzyme aromatase which converts androgens into estrogens by a process called aromatization. In contrast to pre-menopausal women, in whom most of the estrogen in produced in the ovaries, in post-menopausal women most of the body's estrogen is produced in the adrenal gland from the conversion of androgens. ...

| aromatase inhibitor |
A drug that prevents the formation of estradiol, a female hormone, by interfering with an aromatase enzyme. Aromatase inhibitors are used as a type of hormone therapy for postmenopausal women who have hormone-dependent breast cancer.
