Cimetidine and malabsorption of cobalamin
Digestive Diseases and Sciences, 1982Cimetidine in a dosage of 1000 mg daily (200 mg t.i.d. plus 400 mg nocte) reduced the absorption of protein-bound cobalamin by peptic ulcer patients and normal subjects. However, cimetidine in a dosage of 400 mg at night had no significant effect, nor did tripotassium dicitratobismuthate in a dosage of 480 mg daily. Thus long-term administration of 400

Cobalamins and the spectrochemical series
Dalton Transactions, 2008UV-visible-NIR spectra of a variety of cobalamins were run in water and methanol. A broad absorption band (band A) with extinction coefficients of about an order of magnitude less than those of the alphabeta bands was found in the red and NIR regions for Cl-cobalamin (Cl-cbl), Br-cbl, I-cbl, SC(NH(2))(2)-cbl(+) and SeCN-cbl.
