Leading API Manufacturers and Suppliers

1. Zhejiang Hisoar Pharmaceutical Co., Ltd. (China)

   Zhejiang Hisoar is recognized for its specialization in the manufacture of high-potency APIs, including eslicarbazepine acetate. The company boasts advanced synthesis capabilities, good manufacturing practice (GMP) compliance, and export licenses to serve global markets. Their API complies with international pharmacopoeias, notably the US Pharmacopeia (USP), European Pharmacopoeia (EP), and others, making them a prominent source for pharmaceutical companies seeking reliable supply.

2. Hetero Labs Limited (India)

   Hetero, a prominent Indian pharmaceutical and API manufacturer, has diversified its portfolio to include eslicarbazepine acetate. The company leverages state-of-the-art synthesis technology, robust quality assurance processes, and cost-effective manufacturing, serving clients across North America, Europe, and Asia. Hetero's proven track record with epilepsy drug APIs bolsters its credibility as a bulk supplier.

3. Molecular Targeting and API Innovators (Europe & US)

   While not always manufacturing at large scales, select specialty API firms in Europe and North America have developed advanced synthetic routes for eslicarbazepine acetate. These firms often supply research-grade, and in some cases, clinical-phase API batches for investigational drugs and early market entrants.

4. Other Notable API Suppliers

   • Sun Pharmaceutical Industries Ltd. (India): With extensive experience in anticonvulsant APIs, Sun Pharma’s API manufacturing facilities are compliant with regulatory standards, and they have been known to supply eslicarbazepine acetate for various markets.

   • Teva Pharmaceutical Industries Ltd. (Israel): As a major global generic pharmaceutical manufacturer, Teva’s API division provides high-quality APIs for epilepsy medications, including potentially eslicarbazepine acetate, depending on patent status and formulation licensing agreements.

Manufacturing Regions & Regulatory Compliance

Major API manufacturing hubs include China, India, Europe, and the United States. China and India dominate due to their large scale, cost advantages, and technological advancements. However, stringent regulatory environments, such as the US FDA, EMA, and PMDA in Japan, enforce compliance standards that API producers must meet to ensure product quality. Manufacturers with GMP certification and comprehensive quality management systems are preferred, reducing risks related to contamination, impurities, and batch inconsistencies.
