5-alpha reductase inhibitor
(5-AL-fuh ree-DUK-tayz in-HIH-bih-ter)
| A substance that blocks an enzyme needed by the body to make dihydrotestosterone (a male sex hormone made from testosterone). Dihydrotestosterone can cause the prostate to grow. 5-alpha reductase inhibitors are used to shrink an enlarged prostate gland and to improve the flow of urine in a condition called benign prostatic hyperplasia (BPH). A 5-alpha reductase inhibitor is a type of enzyme inhibitor. |
5-fluoro-2-deoxycytidine
(5-FLOOR-oh-2-dee-OK-see-SY-tih-deen)
| A substance being studied in the treatment of some types of cancer. It may prevent the growth of tumors by stopping cancer cells from dividing and by killing them. It is a type of antimetabolite. Also called FdCyd. |
5-fluorouracil
(5-FLOOR-oh-YOOR-uh-sil)
| A drug used to treat symptoms of cancer of the colon, breast, stomach, and pancreas. It is also used in a cream to treat certain skin conditions. 5-fluorouracil stops cells from making DNA and it may kill cancer cells. It is a type of antimetabolite. Also called 5-FU and fluorouracil. |

5-HT3 receptor antagonist
(… reh-SEP-ter an-TA-guh-nist)
| A type of drug used to treat certain types of irritable bowel syndrome and relieve nausea and vomiting. It is a type of antiemetic. Also called 5-hydroxytryptamine 3 receptor antagonist and type 3 serotonin receptor antagonist. |
5-hydroxyindoleacetic acid
(5-hy-DROK-see-IN-dole-uh-SEE-tik A-sid)
| 5HIAA. A breakdown product of serotonin that is excreted in the urine. Serotonin is a hormone found at high levels in many body tissues. Serotonin and 5HIAA are produced in excess amounts by carcinoid tumors, and levels of these substances may be measured in the urine to test for carcinoid tumors. |
5-hydroxytryptamine
(5-hy-DROK-see-TRIP-tuh-meen)
| A hormone found in the brain, platelets, digestive tract, and pineal gland. It acts both as a neurotransmitter (a substance that nerves use to send messages to one another) and a vasoconstrictor (a substance that causes blood vessels to narrow). A lack of 5-hydroxytryptamine in the brain is thought to be a cause of depression. Also called serotonin. |
5-hydroxytryptamine 3 receptor antagonist
(.5-hy-DROK-see-TRIP-tuh-meen 3 reh-SEP-ter an-TA-guh-nist)
| A type of drug used to treat certain types of irritable bowel syndrome and relieve nausea and vomiting. It is a type of antiemetic. Also called 5-HT3 receptor antagonist and type 3 serotonin receptor antagonist. |
506U78
| A drug used to treat certain types of T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LBL). It belongs to the family of drugs called antimetabolites. Also called Arranon and nelarabine. |
5Q minus syndrome
(...MY-nus SIN-drome)
| A rare disorder caused by loss of part of the long arm (Q arm) of human chromosome 5. This syndrome affects myeloid (bone marrow) cells, causing treatment-resistant anemia, and myelodysplastic syndromes that may lead to acute myelogenous leukemia. Also called 5Q- syndrome. |
