Bulk Active Pharmaceutical Ingredient (API) Sources for ORTHO CYCLEN-21

Last updated: July 28, 2025

Introduction

ORTHO CYCLEN-21 is a well-established oral contraceptive tablet containing ethinyl estradiol and norgestimate. The efficacy of this combination hinges on the high-quality bulk Active Pharmaceutical Ingredients (APIs) used in its manufacture. Ensuring reliable sources of these APIs is crucial for pharmaceutical companies aiming to maintain product quality, compliance, and cost-effectiveness. This report examines global API sources for ethinyl estradiol and norgestimate, detailing their manufacturing landscape, regulatory considerations, and strategic sourcing insights.

Overview of ORTHO CYCLEN-21 API Composition

• Ethinyl Estradiol (EE): A synthetic estrogen that acts on estrogen receptors to suppress ovulation.
• Norgestimate: A third-generation progestin that inhibits ovulation and modifies cervical mucus.

Reliable procurement of high-grade APIs—compliant with pharmacopeial standards such as USP, EP, or JP—is essential for product consistency, regulatory approval, and market competitiveness.

Global API Manufacturing Landscape for Ethinyl Estradiol

Major Producers

Ethinyl estradiol's complex synthesis involves multi-step chemical reactions, starting from benzene derivatives. Notable API manufacturers include:

• Dr. Reddy’s Laboratories (India): One of the largest producers of EE, offering APIs that meet international quality standards, supported by their integrated manufacturing facilities [1].
• Mitsubishi Chemical, Japan: Engages in advanced synthesis techniques for high-purity EE, emphasizing compliance with global pharmacopeias.
• Perrigo (Ireland): Specializes in oral contraceptive APIs, including EE, with a focus on cost-effective global supply chains.
• Synthesis Pharma (India/China): Has expanded capacity for EE production, targeting generic pharmaceutical markets [2].

Manufacturing Considerations

• Complexity: EE synthesis requires stringent control over stereochemistry and impurity profiles.
• Regulatory Compliance: Manufacturers must adhere to cGMP standards, with facilities often inspected by regulators such as the FDA, EMA, or PMDA.
• Supply Security: Long-term supply arrangements with reputable manufacturers mitigate shortages and quality risks.
