Cobamamide is one of the active forms of vitamin B12 that is also known as adenosylcobalamin or dibencozide. This drug is available as a nutritional supplement to prevent vitamin B12 deficiency.

Vitamin B12 is a collective term for these variously substituted corrinoids. The principal biochemical participants are two coenzyme forms of Vitamin B12 that are produced and activated in two separate cellular compartments: methylcobalamin in the cytosol and adenosylcobalamin in the mitochondria .

Vitamin B12 (cyancobalamin, Cbl) has two active co-enzyme forms, methylcobalamin (MeCbl) and adenosylcobalamin (AdCbl). There has been a shift in the treatment of vitamin B12 deficiency such that MeCbl is being extensively used and promoted. This exists despite the fact that both MeCbl and AdCbl are necessary for life and have vastly different metabolic fates and functions. MeCbl is mainly involved along with folate in hematopoiesis and the growth of the brain during childhood. Deficiency of AdCbl disturbs the carbohydrate, fat and amino-acid metabolism, and therefore interferes with the formation of myelin. It is therefore important to treat vitamin B12 deficiency with a combination of MeCbl and AdCbl or hydroxocobalamin or cobalamin .

Levoleucovorin is the enantiomerically active form of Folinic Acid (also known as 5-formyl tetrahydrofolic acid or leucovorin). Commercially available leucovorin is composed of a 1:1 racemic mixture of the dextrorotary and levorotary isomers, while levoleucovorin contains only the pharmacologically active levo-isomer. In vitro, the levo-isomer has been shown to be rapidly converted to the biologically available methyl-tetrahydrofolate form while the dextro form is slowly excreted by the kidneys. Despite this difference in activity, the two commercially available forms have been shown to be pharmacokinetically identical and may be used interchangeably with limited differences in efficacy or side effects (Kovoor et al, 2009).

As folate analogs, levoleucovorin and leucovorin are both used to counteract the toxic effects of folic acid antagonists, such as methotrexate, which act by inhibiting the enzyme dihydrofolate reductase (DHFR). They are indicated for use as rescue therapy following use of high-dose methotrexate in the treatment of osteosarcoma or for diminishing the toxicity associated with inadvertent overdosage of folic acid antagonists. Levoleucovorin, as the product Fusilev (FDA), has an additional indication for use in combination chemotherapy with 5-fluorouracil in the palliative treatment of patients with advanced metastatic colorectal cancer.

Folic acid is an essential B vitamin required by the body for the synthesis of purines, pyrimidines, and methionine before incorporation into DNA or protein. However, in order to function in this role, it must first be reduced by the enzyme dihydrofolate reductase (DHFR) into the cofactors dihydrofolate (DHF) and tetrahydrofolate (THF). This important pathway, which is required for de novo synthesis of nucleic acids and amino acids, is disrupted when high-dose methotrexate is used for cancer therapy. As methotrexate functions as a DHFR inhibitor to prevent DNA synthesis in rapidly dividing cells, it also prevents the formation of DHF and THF. This results in a deficiency of coenzymes and a resultant buildup of toxic substances that are responsible for numerous adverse side effects of methotrexate therapy. As levoleucovorin and leucovorin are analogs of tetrahydrofolate (THF), they are able to bypass DHFR reduction and act as a cellular replacement for the co-factor THF, thereby preventing these toxic side effects.

Uses

Cobamamide is an ingredient found in a variety of supplements and vitamins.

Levoleucovorin is a folate analog used after high dose methotrexate for osteosarcoma, to reduce the toxic effects of folate analogs, and with 5-fluorouracil in palliative treatment of advanced metastatic colorectal cancer.

Levoleucovorin is indicated for use as rescue therapy following high-dose methotrexate in the treatment of osteosarcoma or for diminishing the toxicity associated with inadvertent overdosage of folic acid antagonists. Levoleucovorin, as the product Fusilev (FDA, dosed at one-half the usual dose of racemic d,l-leucovorin), has an additional indication for use in combination chemotherapy with 5-fluorouracil in the palliative treatment of patients with advanced metastatic colorectal cancer (although they should not be mixed in the same infusion as a precipitate may form).

Biopar delta-FORTE is also used to associated treatment for these conditions: Malnutrition, Vitamin B12 Deficiency, Weight Loss, NutritionAdvanced Colorectal Cancer, Folic acid antagonist overdose, Metastatic Colorectal Cancer (MCRC), Rescue after high-dose methotrexate therapy in osteosarcoma
