Methotrexate, formerly known as amethopterin, is a chemotherapy agent and immune-system suppressant. [4] It is used to treat cancer , autoimmune diseases , and ectopic pregnancies . [ 4 ] Types of cancers it is used for include breast cancer , leukemia , lung cancer , lymphoma , gestational trophoblastic disease , and osteosarcoma . [ 4 ]
Physiologically based pharmacokinetic (PBPK) modeling is a mathematical modeling technique for predicting the absorption, distribution, metabolism and excretion (ADME) of synthetic or natural chemical substances in humans and other animal species. PBPK modeling is used in pharmaceutical research and drug development, and in health risk ...
In addition to a role in intestinal absorption, RFC is expressed in virtually all tissues and is the major route of delivery of folate to cells within the systemic circulation under physiological conditions. When pharmacological amounts of folate are taken as a dietary supplement, absorption also takes place by a passive diffusion-like process.
Methotrexate also indirectly inhibits purine synthesis by blocking the metabolism of folic acid (it is an inhibitor of the dihydrofolate reductase). Allopurinol is a drug that inhibits the enzyme xanthine oxidoreductase and, thus, lowers the level of uric acid in the body. This may be useful in the treatment of gout, which is a disease caused ...
Antifolate. Antifolates are a class of antimetabolite medications that antagonise (that is, block) the actions of folic acid (vitamin B 9). [1] Folic acid's primary function in the body is as a cofactor to various methyltransferases involved in serine, methionine, thymidine and purine biosynthesis. Consequently, antifolates inhibit cell ...
Folinic acid, also known as leucovorin, is a medication used to decrease the toxic effects of methotrexate and pyrimethamine. [2][3] It is also used in combination with 5-fluorouracil to treat colorectal cancer and pancreatic cancer, may be used to treat folate deficiency that results in anemia, and methanol poisoning. [3][4] It is taken by ...
Drugs secreted in the kidney. This is a table of drugs that are secreted in the kidney. Acid medication are, because of pH partition, secreted to a higher extent when urine is basic. In the same way, basic medications are secreted to a higher extent when urine is acidic. Medication.
A prodrug is a pharmacologically inactive medication or compound that, after intake, is metabolized (i.e., converted within the body) into a pharmacologically active drug. [1][2] Instead of administering a drug directly, a corresponding prodrug can be used to improve how the drug is absorbed, distributed, metabolized, and excreted (ADME). [3][4]
