Folinic acid calcium 生物活性

描述 Calcium Folinate (CF) is a biological folic acid and is generally administered along with methotrexate (MTX) as a rescue agent to decrease MTX-induced toxicity. Endosalpingitis, the ultrastructural damage of endosalpinx, and a change in estrogen and P receptor expression induced by low- and high-dose MTX (methotrexate) in endosalpinx can be reversed completely and partly (B1, B2) by combined treatment with CF, suggesting that CF combined with MTX protects against the side effects induced by MTX[3]. Uracil and tegafur (UFT) plus calcium folinate are the components of the oral agent known as Orzel, which offers activity comparable to intravenously administered 5-fluorouracil (5-FU) combined with calcium folinate[4]. UFT (uracil and tegafur) plus oral calcium folinate (Orzel) offers significant antitumor activity and an acceptable toxicity profile makes this a logical formulation for the adjuvant treatment of colon cancer[5]. Furthermore, tegafur/uracil + calcium folinate is well tolerated, with dose-limiting toxicity manifesting as diarrhoea. Compared with intravenous fluorouracil plus folinic acid (leucovorin) regimens, tegafur/uracil + calcium folinate has similar efficacy with less toxicity and is more convenient because it is an oral regimen[6].
