Capecitabine (154361-50-9) API Manufacturers & Suppliers in India: A Comprehensive OvervieCapecitabine (154361-50-9)
Capecitabine, identified by the CAS number 154361-50-9, is an oral chemotherapy drug used in the treatment of various types of cancer, most notably breast cancer, colorectal cancer, and gastric cancer. It is a prodrug, meaning that it is converted into its active form, 5-fluorouracil (5-FU), in the body. 5-FU then works to inhibit the synthesis of DNA and RNA, effectively killing cancer cells by preventing them from replicating.
Therapeutic Uses and Mechanism of Action
- Breast Cancer: Capecitabine is commonly used in the treatment of metastatic breast cancer that is resistant to other chemotherapeutic agents such as anthracyclines and taxanes.
- Colorectal Cancer: It is frequently used in combination with other chemotherapeutic drugs to treat metastatic colorectal cancer.
- Gastric Cancer: In certain cases, Capecitabine is used in combination therapies to treat gastric cancer, particularly in patients who have failed previous treatments.
- Mechanism of Action: Capecitabine is metabolized in the liver and converted into 5-FU, which then interferes with the normal function of DNA and RNA by inhibiting thymidylate synthase, an enzyme crucial for DNA replication. This leads to the death of rapidly dividing cancer cells.
Capecitabine in Cancer Treatment: Targeting Cancer Cells
Advantages Over Other Chemotherapies
- Oral Administration: One of the major advantages of Capecitabine over traditional chemotherapy drugs is that it can be administered orally. This is beneficial for patients, as it avoids the need for injections or intravenous infusion, which can be inconvenient and painful.
- Selective Targeting: Capecitabine is designed to target cancer cells more selectively, converting into 5-FU primarily in the tumor cells. This selective activation helps reduce side effects associated with systemic chemotherapy, making it a preferred choice for many patients.
Clinical Studies and Efficacy
- Breast Cancer: Capecitabine has demonstrated its effectiveness in clinical trials when combined with other drugs like docetaxel, especially in patients with HER2-negative metastatic breast cancer.
- Colorectal Cancer: In colorectal cancer, Capecitabine has been shown to improve survival rates, particularly when combined with other agents such as oxaliplatin (FOLFOX regimen).
- Gastric Cancer: In gastric cancer treatment, studies suggest that Capecitabine offers significant benefits in combination with other chemotherapeutic drugs like oxaliplatin.
Capecitabine API: Manufacturing and Supply in India
India plays a crucial role in the global supply of oncology APIs, including Capecitabine. The country’s ability to produce highly complex, highly potent, semi-synthetic APIs like Capecitabine has positioned it as a leader in global pharmaceutical production. This section covers the manufacturing process, technological infrastructure, and the role of WHO GMP-certified facilities in ensuring high-quality production.
1. Capecitabine API Production Process
The production of Capecitabine API involves several steps, each requiring careful control to maintain the quality, safety, and efficacy of the final product.
Step 1: Synthesis of Capecitabine
- The production of Capecitabine starts with the synthesis of its precursor compound. This is typically achieved through chemical synthesis, which involves several key steps:
- The precursor compound undergoes a series of chemical reactions to form the active Capecitabine molecule.
- Key reagents and catalysts are used during the synthesis process to ensure high purity and yield.
Step 2: Conversion to Active Form (5-FU)
- After synthesis, Capecitabine is metabolized in the body to its active form, 5-FU, which is responsible for its anticancer activity. However, during the manufacturing process, the molecule itself is in its inactive form (prodrug) until it reaches the liver and tumor cells.
Step 3: Purification and Quality Control
- After synthesis, Capecitabine undergoes purification to remove any impurities or by-products that may have formed during the synthesis process. This ensures the purity and potency of the final product.
- Several purification techniques, such as high-performance liquid chromatography (HPLC), recrystallization, and filtration, are used to ensure the product meets the required quality standards.
Step 4: Packaging and Distribution
- Once purified, Capecitabine is packaged according to pharmaceutical standards for distribution. This includes ensuring that the product is stable during storage and shipping, which is essential to maintain its therapeutic effectiveness.
2. Manufacturing Standards in India
Indian pharmaceutical manufacturers adhere to rigorous international standards in their production of oncology APIs like Capecitabine. Some of the key standards include:
- WHO-GMP Certification: Indian manufacturers of Capecitabine API are typically certified by the World Health Organization (WHO), ensuring that the production process complies with the highest standards of Good Manufacturing Practices (GMP). This certification is critical for global trade and ensures the safety and quality of the products.
- International Regulatory Compliance: Indian facilities often meet the regulatory standards of various global authorities, including the U.S. FDA, European Medicines Agency (EMA), and Australian TGA, which allows Indian manufacturers to supply Capecitabine to countries around the world.
India as a Global Supplier of Capecitabine API
India has emerged as a leading global supplier of Capecitabine API due to its competitive pricing, high-quality production, and regulatory compliance. The following factors contribute to India’s dominance in the oncology API market.
1. Cost Efficiency and Competitive Pricing
- Indian manufacturers benefit from cost-effective labor, raw materials, and production infrastructure, which allow them to produce high-quality oncology APIs like Capecitabine at a fraction of the cost in Western countries. This affordability enables Indian producers to supply Capecitabine API to developing markets where access to costly cancer therapies is a significant barrier.
2. Technological Advancements in API Manufacturing
- India’s pharmaceutical industry has invested heavily in the latest pharmaceutical technologies and automation to improve the manufacturing process. This has resulted in enhanced production efficiency, reduced costs, and the ability to scale production to meet global demand.
3. Strong Regulatory Framework and Compliance
- Indian manufacturers of Capecitabine API comply with stringent international regulations and standards, ensuring that the APIs produced meet the required pharmacological quality and safety standards.
