In the complex landscape of cancer chemotherapy, adjunct therapies play a crucial role in enhancing treatment efficacy and managing side effects. Among these, Calcium Folinate, also known as Leucovorin or Calcium Folinate, stands out as a critical pharmaceutical intermediate. Its primary function is to counteract the toxic effects of folic acid antagonists, most notably Methotrexate, a widely used chemotherapy drug. Understanding the nuances of Calcium Folinate is paramount for healthcare professionals and pharmaceutical procurement managers.

Methotrexate, while effective against various cancers by inhibiting dihydrofolate reductase (DHFR), can cause severe systemic toxicity, particularly to rapidly dividing cells like those in the bone marrow and gastrointestinal tract. This is where Calcium Folinate, a formyl derivative of tetrahydrofolic acid, steps in. It acts as a reduced folate source, bypassing the DHFR enzyme that Methotrexate inhibits, thereby 'rescuing' normal cells from its damaging effects. This process, often referred to as 'Leucovorin rescue,' is a cornerstone in high-dose Methotrexate protocols for treating osteosarcoma, lymphomas, and certain leukemias.

For procurement managers and researchers seeking a reliable Calcium Folinate manufacturer in China, sourcing high-purity material is essential. We pride ourselves on being a leading pharmaceutical intermediate supplier, offering Calcium Folinate (CAS 1492-18-8) with a guaranteed purity of 98%. This commitment to quality ensures that our clients receive a product suitable for rigorous pharmaceutical applications. Purchasing Calcium Folinate for sale from us means gaining access to a product that meets stringent international standards.

Beyond its role in Methotrexate rescue, Calcium Folinate is also employed in combination chemotherapy regimens, such as with Fluorouracil (5-FU), to enhance the latter's cytotoxic effect against colorectal cancer. Its ability to modulate the folate pool and stabilize the binding of 5-FU to thymidylate synthase contributes to improved patient outcomes. This multifaceted application underscores the demand for consistent and high-quality folic acid calcium price inquiries from global markets.

When looking to buy folinic acid in bulk or as a specific CAS 1492-18-8 chemical, it’s vital to partner with a supplier that emphasizes not only product quality but also supply chain reliability. Our extensive experience as an exporter ensures that we can meet the needs of pharmaceutical companies and research institutions worldwide. We understand that timely delivery and competitive Calcium Folinate price are critical factors for our clients.

In summary, Calcium Folinate is an indispensable compound in modern chemotherapy. Its ability to mitigate drug toxicity and enhance therapeutic efficacy makes it a highly sought-after pharmaceutical intermediate. For those in the market to buy Calcium Folinate, choosing a reputable pharmaceutical raw material supplier in China like ourselves guarantees access to premium quality products and dedicated support for your critical medical applications.
