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. ...

Some histamine-2 receptor blocker medications like Zantac were initially ruled out as safe by the FDA. It was a drug for patients who experience heartburn and other gastrointestinal illnesses. Individuals with gastroesophageal reflux disease (GERD) and excessive stomach acid could also take the medicine to keep their health condition under control.

However, laboratories like Valisure determined that it contained compounds that may harm a person’s health. There was an abnormally high level of n-nitrosodimethylamine (NDMA) found in the medicine, making it dangerous. If consumed in high doses, NDMA is a volatile compound that can cause cancer. This means those who are taking Zantac regularly may have been at risk of developing a life-threatening disease due to the drug.

Due to its potential health risks, FDA pulled out Zantac and other ranitidine medications from the market. The drug manufacturers also faced repercussions after many patients filed lawsuits for the inconveniences they’ve experienced.

Lessons For The Drug Industry

To prevent similar cases from occurring in the future, here are some things the drug industry should learn from the Zantac incident:

  1. External Factors May Affect Medicine Composition

The manufacturing and transportation process of the ulcer medication exposed it to various temperature changes, which affected its composition. Two drug manufacturers were located in Australia and India, where the temperature can go as high as 139 degrees Fahrenheit during the summer. The NDMA found in ranitidine can significantly increase when stored in heat, and its manufacturing process made it prone to changes.

This means some ranitidine products sold in the market may have been exposed to heat several times before it even arrives in stores. Additionally, there weren’t any instructions indicating the proper storage temperature of the drug during transport. Thus, there’s no guarantee that the drug was kept in cool storage at all times.

It wasn’t long before experts determined that Zantac may be dangerous to the health of people who took it regularly. Thus, it may be best for drugmakers to consider how their products are transported and distributed as this can affect the efficacy and safety of drugs. Furthermore, it may be helpful to provide detailed instructions on how to handle a medicine to ensure it won’t be compromised before it even reaches consumers.

  1. Drug Makers Shouldn’t Withhold Information From Patients

After Zantac was pulled out from the market, various patients who claimed to have developed cancer due to the drug filed lawsuits against its manufacturers. Cases were filed in court against companies that produced and distributed the drug. Sanofi, Boehringer Ingelheim, Pfizer, and GlaxoSmithKline received various complaints from patients.

Some plaintiffs claimed that the people behind the drug knew about its potential risks but chose not to disclose it to the public. The lack of information led some individuals seeking relief for their gastrointestinal problems to take medicine without fully knowing its risks.

Other than the possibility of developing various forms of cancer, some patients who took Zantac also showed severe side effects. Taking ranitidine medication may also cause liver failure, blurred vision, hepatitis, and stomach pain.

Those who wish to ask for compensation for their losses can stay updated through reliable sources, like Drug Injury News, or keep in touch with lawyers handling Zantac cases.

  1. Alternatives Can Be Given To Patients

Patients who were previously prescribed Zantac were advised to seek medical help if they’ve been experiencing adverse effects from taking the drug. Additionally, FDA suggested other over-the-counter medicines as substitutes to ranitidine.

Some medications like Pepcid (famotidine), Nexium (omeprazole and esomeprazole), or Prevacid (lansoprazole) can be given to individuals who need medicine to regulate their stomach acid. These products are confirmed as safe substitutes to ranitidine and aren’t affected by the contaminants in Zantac products.

Although these over-the-counter drugs are ruled as safe for consumption, patients who need a Zantac are still advised to consult a physician before buying a new ulcer medication. It’s best to get their condition checked to ensure they won’t encounter problems when taking their new prescription.

Furthermore, those who regularly take the drug to prevent heartburn and overproduction of stomach acid should report any adverse effects to their doctor. Doing so will help avoid any health problems from developing.

Final Thoughts

The Zantac case is an unfortunate incident that affected the lives of many people. Some patients claimed to have developed long-term health problems due to the medication.

Fortunately, the ulcer medication is no longer available in stores. Instead, safer alternatives are prescribed to those who need relief from gastrointestinal problems. Furthermore, individuals who wish to receive compensation for the troubles they’ve experienced can file lawsuits against the manufacturers of the drug.
