In 2023, the pharmaceutical industry, particularly antibiotic manufacturers, has experienced a range of changes that span from supply chain challenges to new regulatory opportunities. A recent insight from the Access to Medicine Foundation has brought attention to the issue of waste management in antibiotic manufacturing and outlined steps that pharmaceutical companies can take to mitigate the risk of antimicrobial resistance (AMR).

The report strongly emphasizes that pharmaceutical companies must acknowledge the environmental impact of their manufacturing practices, particularly regarding antibiotic waste throughout the supply chain. An illustration of the urgency came in January 2023 when a global shortage of the antibiotic amoxicillin coincided with a surge in respiratory infections, leading to increased antibiotic demand. The European Medicines Agency (EMA) noted that this challenge resulted in manufacturing delays and production capacity issues. In response, the EMA announced recommendations for manufacturers in July 2023 to prepare for anticipated winter antibiotic shortages.

The report highlights the British Standards Institute (BSI)’s groundbreaking certification for Minimized Risk of Antimicrobial Resistance (AMR) in antibiotic manufacturing, launched in June 2023. This certification underscores the growing importance of demonstrating responsibility in this critical area.

One significant challenge outlined in the report is the absence of regulations specifically targeting antibiotic discharge from manufacturing sites worldwide. Currently, positive actions in this regard are voluntary. However, the report provides proactive examples of companies demonstrating good practice, including GSK, Pfizer, Novartis, Sandoz (a unit of Novartis), Teva, and Viatris.

The report offers recommendations for antibiotic manufacturers to make meaningful progress in reducing the risk of AMR during the manufacturing process:

  • Proactive Antibiotic Waste Management: Notably, firms like GSK and Pfizer report compliance with discharge limits at most of their upstream suppliers. GSK, for instance, declares 100 percent compliance at supplier sites, while Pfizer reports over 86 percent compliance among its suppliers. This demonstrates the feasibility of achieving compliance on a larger scale, but transparency and accountability throughout the supply chain are essential.
  • Effective Wastewater Management: The report recommends establishing, quantifying, and monitoring discharge limits to ensure wastewater safety at manufacturing sites. Companies should develop comprehensive wastewater treatment processes to minimize AMR risk effectively. A case study on Sandoz’s use of membrane filtration to remove bacteria from wastewater is provided.
  • Transparency Across the Supply Chain: Pharmaceutical companies have the capacity to support suppliers in achieving compliance with discharge limits. Collaboration is vital for the sustainability of the antibiotic supply chain, given the dependence on a limited number of API producers.

Notably, the report highlights that no company currently reports actual antibiotic discharge levels at its own or supplier sites. Investing in responsible manufacturing can help companies combat rising drug resistance while aligning with market expectations for environmental and sustainable practices.

The report also touches on the future of the antibiotic supply chain, suggesting that regulations aimed at reducing AMR risk from manufacturing may be introduced or strengthened in various countries. By following the recommendations outlined in the Access to Medicine Foundation report, pharmaceutical companies can ensure their antibiotic production aligns with responsible manufacturing principles and meets stakeholders’ increasing expectations for environmental responsibility.

In July 2023, the Responsible Antibiotics Manufacturing Platform (RAMP) published a framework to evaluate and verify a company’s manufacturing practices in reducing the risks of antimicrobial resistance (AMR), further emphasizing the need for responsible manufacturing in the industry.

Managing Quality and Regulatory Risks in Pharmaceutical Technology Transfer

Technology transfer moves more than manufacturing instructions. It moves process knowledge, supplier dependencies, labeling requirements, packaging specifications, and the evidence needed to demonstrate control. For medical device manufacturers, including those supporting drug-device combination products, these interfaces can become recurring sources of compliance gaps during site transitions, acquisitions, and remediation. The central problem is often not a missing procedure. It is a quality system that allows connected activities to change independently. A label revision may be approved while packaging artwork, supplier instructions, or production-system data still reflect an obsolete version. Staying inspection-ready requires manufacturers to manage these dependencies as one controlled system. Why Compliance Gaps Keep Recurring Findings are treated as documentation defects Revising a procedure can resolve an immediate discrepancy without changing the behavior that caused it. If unclear decision rights, weak escalation, or ineffective training remain, the same failure may surface elsewhere. Corrective and preventive action should distinguish the observed finding from its underlying cause and establish how effectiveness will be demonstrated. Ownership is divided across connected functions Quality, Regulatory Affairs, labeling, packaging engineering, operations, suppliers, and digital-system owners often maintain separate workflows. Each team may complete its assigned task while an interface remains uncontrolled. For example, changing an instruction for use can affect packaging configuration, translations, technical documentation, inventory disposition, and release controls. Transitions expose unresolved weaknesses Acquisitions and site transfers can introduce conflicting procedures, incomplete knowledge transfer, or different assumptions about validated processes. Regulatory changes add further demands. When these events coincide with CAPA or change-control backlogs, teams may prioritize administrative closure over risk reduction. Without a coordinated impact assessment, local fixes can create new gaps downstream. Establish the Regulatory Baseline Inspection readiness starts with knowing which requirements apply to the product, activity, and market. Pharmaceutical, device, and combination-product obligations are not interchangeable; transfer planning should identify the applicable requirements rather than assume one quality framework covers every operation. According to FDA’s Quality Management System Regulation overview and FAQs, the QMSR became effective on February 2, 2026, incorporates ISO 13485:2016 by reference, and introduced the updated device inspection process under Compliance Program 7382.850. ISO 13485 certification does not exempt a manufacturer from FDA inspection or guarantee compliance with FDA requirements. For devices marketed in the European Union, Regulation (EU) 2017/745, Annex I, Section 23, provides the primary requirements for information supplied with devices, including labels and instructions for use. Teams should assess the applicable provisions alongside relevant language, product-specific, and market requirements. A labeling review should therefore evaluate required content and consistency with the device’s intended purpose and supporting documentation—not merely artwork accuracy. How to Identify the Real Gaps Begin with a cross-functional assessment that follows actual product and information flows. Select representative transfers, label changes, supplier changes, and CAPAs, then trace each from initiation through implementation and effectiveness review. Map dependencies: Identify affected specifications, suppliers, packaging components, systems, validation activities, and training. Compare records with practice: Check whether approved procedures match what operators and reviewers actually do. Test traceability: Follow a requirement through technical documentation, labeling, production instructions, and release evidence. Examine recurrence: Look for repeated deviations, reopened actions, overdue changes, and findings shared across sites. Assess capacity: Determine whether qualified owners have enough time and authority to complete corrective work. Prioritize gaps by potential patient or user harm, regulatory impact, likelihood of recurrence, and detectability. Document the rationale; an old overdue item is not automatically more important than a newly identified high-risk weakness. Align Quality, Labeling, Packaging, and Change Control Create a coordinated remediation plan with one accountable owner for each action, named contributors, acceptance criteria, and required evidence. Separate immediate containment from systemic correction. Containment might prevent obsolete labels from being issued; correction might redesign approval and implementation controls so obsolete versions cannot return. Use change control as the integration point. Before approval, evaluate effects on regulatory submissions or notifications, technical documentation, supplier controls, packaging performance, validation, electronic master data, inventory, and training. Record both identified impacts and justified decisions that particular activities are unaffected. During technology transfer, define readiness gates before production or release responsibilities move. These should address the transfer of process knowledge, acceptance criteria, receiving-site capability, required qualification or validation, approved documents, and personnel competence. The appropriate evidence depends on the product and process; a generic checklist cannot replace a documented assessment. Finally, verify implementation where the work happens. Confirm that current instructions are available, suppliers received approved requirements, systems contain correct versions, and affected personnel can perform their tasks. A signed approval is not evidence that every downstream change took effect. Mistakes That Undermine Inspection Readiness Closing CAPAs on task completion alone: Effectiveness checks should test whether the underlying failure has been controlled. Updating labels in isolation: Assess packaging, supplier, system, documentation, and inventory consequences. Counting closures instead of evidence: Dashboards need defensible records behind their status indicators. ...
