Bulk Active Pharmaceutical Ingredient (API) Sources for PEXEVA (Perampanel)

Last updated: July 29, 2025

---

Introduction

Perampanel, marketed under the brand name PEXEVA, is a potent antiseizure medication used primarily in the treatment of partial-onset seizures and certain types of epilepsy. As a highly selective non-competitive AMPA receptor antagonist, its efficacy hinges on the purity and quality of its active pharmaceutical ingredient (API). For pharmaceutical manufacturers and distributors, sourcing reliable bulk APIs is critical to ensure product safety, regulatory compliance, and supply chain stability. This report investigates current API suppliers, global manufacturing hubs, quality standards, and strategic considerations in sourcing PEXEVA APIs.

Overview of PEXEVA (Perampanel) API

Perampanel, chemically known as 2,3-dihydro-1H-inden-5-yl 2-methyl-5-oxo-5-phenyl-1,3-oxazolidin-4-ylcarbamate, is a novel anti-epileptic agent approved by regulatory agencies such as the FDA and EMA. Its complex chemical structure demands high standards in synthesis, purification, and formulation quality. The API must meet stringent specifications, including potency, purity (typically >99%), residual solvents, heavy metals, and chiral purity.

Global API Manufacturing Landscape

Major API Manufacturing Regions

The production of PEXEVA API largely occurs within established pharmaceutical manufacturing hubs in India, China, Europe, and the United States:

• India: Known for a robust API industry, India hosts several integrated API manufacturing facilities capable of producing complex molecules like perampanel. Companies such as Sun Pharma, Lupin, and Dr. Reddy’s have extensive API plants adhering to Good Manufacturing Practices (GMP).

• China: China’s API sector has expanded significantly, offering cost-effective manufacturing with advanced chemical synthesis capabilities. Notable players include Zhejiang Huahai Pharmaceutical and Zhejiang Hisun Pharmaceutical.

• Europe: European manufacturers such as Evonik and pharmaceutical giants like Novartis maintain high-quality API factories, often catering to markets with strict regulatory requirements.

• United States: Although less prevalent, some US-based firms focus on the synthesis and supply of high-purity APIs for niche markets, complying with FDA standards.

Key Suppliers and Manufacturers

The following list highlights well-established API manufacturers potentially capable of supplying bulk perampanel API:

Supplier	Region	Certifications	Notes
Sun Pharma Advanced Research	India	GMP, ISO 9001, ISO 14001	Large-scale API production, proven compliance
Zhejiang Huahai Pharmaceutical	China	GMP, CEP, ISO 9001	Focus on complex molecules, cost advantage
Dr. Reddy’s Laboratories	India	GMP, USFDA/EMA approvals	Extensive API portfolio, reliable supply chain
Evonik Industries	Europe	GMP, ISO 9001, ICH Q7	Specialized in high-quality APIs and intermediates

Regulatory and Quality Considerations

API suppliers for PEXEVA must adhere to strict GMP standards to ensure safety and efficacy. Suppliers should possess certifications such as Current GMP (cGMP), Certificate of Suitability (CEP) from the European Directorate for the Quality of Medicines & HealthCare (EDQM), or US FDA approvals, indicating rigorous quality compliance.

Importantly, perampanel’s complex synthesis demands sophisticated purification processes to eliminate impurities, especially chiral impurities, residual solvents, and organometallic residues. Suppliers with proven analytical capabilities and comprehensive quality control (QC) labs are preferred.

Supply Chain and Risk Management

The global API supply chain faces multiple risks, including geopolitical tensions, regulatory changes, and manufacturing disruptions (e.g., due to the COVID-19 pandemic). Considerations for sourcing API for PEXEVA include:

• Diversification: Engaging multiple suppliers across regions reduces dependency risks.
• Verification: Auditing suppliers’ GMP compliance and capacity.
• Regulatory Alignment: Ensuring suppliers can meet the regulatory requirements of target markets.
• Lead Time Management: Establishing reliable communication channels to forecast demand accurately.
