ALREX, the brand-name ophthalmic corticosteroid containing loteprednol etabonate, has a well-established supply chain involving multiple stakeholders. The drug’s suppliers include the originator company, generic manufacturers, and active pharmaceutical ingredient (API) producers. Bausch & Lomb, the original manufacturer, continues to supply the branded product, while companies like Lupin, Amneal, and Padagis US have entered the market with FDA-approved generic equivalents[1][7]. API suppliers such as Axplora, Aarti Pharmalabs, and Curia support global production through specialized chemical synthesis[13][15]. This report details the key suppliers, regulatory milestones, and market dynamics shaping ALREX’s availability.
Originator and Branded Product Suppliers
Bausch & Lomb Inc.
As the developer and original manufacturer of ALREX, Bausch & Lomb Inc. retains a central role in its supply chain. The company’s facility in Rochester, New York, oversees the production of the branded 0.2% ophthalmic suspension[10]. Bausch & Lomb has also collaborated with Pfizer to co-promote ALREX alongside other ophthalmic products, enhancing its market reach[11]. The brand’s annual U.S. sales were approximately $29.1 million as of October 2023, underscoring its commercial significance[14].
Regulatory and Manufacturing Compliance
Bausch & Lomb adheres to FDA Good Manufacturing Practices (GMP) and holds Reference Listed Drug (RLD) status for ALREX, ensuring bioequivalence standards for generic versions[1][10]. The company’s portfolio includes related products like Lotemax and Inveltys, which share loteprednol etabonate as the active ingredient but differ in formulation strengths[12].
Generic Drug Manufacturers
Lupin Limited
Lupin Limited received FDA approval in December 2023 for its generic loteprednol etabonate ophthalmic suspension (0.2%), manufactured at its Pithampur facility in India[7]. This approval marked Lupin’s entry into the U.S. market as a key generic supplier, leveraging cost efficiencies to compete with the branded product. Lupin’s generic version is bioequivalent to ALREX and addresses seasonal allergic conjunctivitis, mirroring the brand’s indications[7][14].
Amneal Pharmaceuticals
Amneal Pharmaceuticals secured FDA approval for its generic ALREX in December 2024, further diversifying the supplier landscape[1]. The company’s expertise in ophthalmic suspensions positions it as a reliable alternative for healthcare providers seeking cost-effective treatments.
Other Generic Suppliers
Additional suppliers include Sentiss Pharma (approved April 2023) and Padagis US (approved July 2024), both offering 0.2% loteprednol etabonate suspensions[1]. These manufacturers contribute to price competition and increased accessibility, particularly in markets where patent protections have expired.
Active Pharmaceutical Ingredient (API) Suppliers
Axplora
Axplora, formed through the merger of Farmabios and Novasep, specializes in API manufacturing and supplies loteprednol etabonate to formulation developers[13][15]. The company’s GMP-compliant facilities ensure high-quality raw materials for ophthalmic suspensions, aligning with global regulatory standards.
Aarti Pharmalabs
Aarti Pharmalabs, based in India, produces loteprednol etabonate APIs for generic drug manufacturers. Its cost-competitive synthesis processes support large-scale production, particularly for markets in Asia and North America[13][16].
Curia
Curia (formerly AMRI) offers custom API synthesis services, including loteprednol etabonate, for pharmaceutical companies requiring tailored chemical solutions[15]. The company’s expertise in steroidal compounds enhances its role in the ALREX supply chain.
Distribution Networks and Market Dynamics
Regional Distribution Channels
In Canada, PharmaServe and Canadian Pharmacy World distribute ALREX directly to consumers, emphasizing affordability and accessibility[2][6]. These platforms source products from licensed dispensaries in jurisdictions such as Singapore, Mauritius, and the United Kingdom, ensuring compliance with international safety standards[6].
Pricing Considerations
The branded ALREX suspension retails at approximately $326 for a 5-mL bottle, while generic versions cost between $235 and $643 depending on volume[9]. API pricing fluctuates based on production scale, with suppliers like LGM Pharma and Guangzhou Topwork Chemical offering competitive rates for bulk purchases[13][16].
Regulatory and Patent Landscape
Patent Expiry and Exclusivity
ALREX’s initial patent expired in 2018, enabling generic entrants like Lupin to file Abbreviated New Drug Applications (ANDAs)[1][7]. Bausch & Lomb retains exclusivity through secondary patents covering formulation optimizations, though these face ongoing challenges from generic manufacturers[14].
Compliance and Quality Assurance
API suppliers must submit Drug Master Files (DMFs) to the FDA, detailing manufacturing processes and quality controls[15]. For instance, Zach System SA (a Zambon subsidiary) provides DMF-certified loteprednol etabonate, ensuring adherence to U.S. pharmacopeial standards[13][16].
Challenges and Future Outlook
Counterfeit Risks
The proliferation of unauthorized online pharmacies selling counterfeit ALREX poses significant safety risks[1]. Legitimate suppliers like CVS Pharmacy and Universal Drugstore emphasize verification protocols to mitigate this issue[4][5].
Market Expansion
The global ocular drug delivery market, projected to reach $39 billion by 2032, drives demand for ALREX and its generics[14]. Emerging suppliers in India and China are likely to intensify competition, further reducing prices and expanding access in underserved regions.
