In-Process Control for Drug Delivery Systems

In-process control (IPC) tests are performed at regular intervals to ensure product quality and specifications are met at all stages of production. Continuous testing helps detect manufacturing quality drift and triggers corrective actions on time. Receive assurance throughout the production process.

Sartorius’ solutions support environmental, contamination and in-process controls to ensure conformity to defined specifications. Evaluate correct dose delivery for transdermal patches, auto-injectors, syringes or nasal sprays. Test inhalers regarding moisture content or particulate matter before filling with the active drug. Check the sterility of drug-eluting stents or perform a weigh test to validate the antimicrobial coating of a catheter.

In-Process Control Applications for Drug Delivery Systems

Check Smallest Quantities

Extended wear, delivery of drugs, biocompatibility or corrosion resistance - coatings on drug delivery systems provide numerous benefits. To fulfill their function reliably, coatings, protection layers and foils must be picked up uniformly. 

Weighing by difference solutions from Sartorius are your best fit to verify that coating systems have applied the exact amount of medical grade polymer or API to an implantable device, such as a DES (Drug Eluting Stent). For reliable, reproducible and straightforward weighing workflows:

  • Highest precision for smallest quantities, protected against drafts and electrostatic charges
  • Sample holders accommodate differently shaped products
  • Full data traceability and integrity
  • Compliant to 21 CFR part 11 and EU Annex 11

Determine Moisture Contents Within Minutes

Every material processed during production needs a specific and constant moisture content for optimal processing and functionality of the final product. Even the smallest deviations can be captured by moisture analyzers.

Sartorius offers robust and reliable solutions so you can accurately detect and document lowest moisture contents quickly and easily within your routine applications: 

  • Measure minimum moisture content down to 0.005 %
  • Process up to 4 samples simultaneously
  • Achieve highest precision, even for very dry samples
  • Compliant to ASTM Standard D6980, ISO 868-7 Annex E

Maximum Recovery in Minimum Time

ISO 10993-1 requests a safety evaluation and risk assessment to exclude potential harmful effects of nanomaterials. Prior to evaluating reference values like conjugation or encapsulation efficiency, zeta potential and size distribution, a successful purification and concentration of the suspension or dispersion is essential. However, typical separation methods like size-exclusion chromatography and diafiltration require extensive, costly and time-consuming manual handling and subsequent concentration steps. 

Sartorius‘ Ultrafiltration Solution moves you one step ahead:

  • Perform purification and concentration steps simultaneously and reduce manual handling time
  • Highest recovery in the fastest possible time
  • Save consumable costs

Capture and Quantify Smallest Particles

GMP Annex 1 requests that medical devices be scrupulously clean and free of interfering residues. From raw material or environment, clothing, machining and lubricants, particle sources are manifold. Glass, elastomer, hair and other particles can affect biocompatibility and safety as they build an additional surface for microbial growth, or worst case can be released and lodged in a patient's vascular capillary system. 

Sartorius’ solutions are designed for capturing particulate matter, reliable optical analysis and accurate quantification:

  • Ready-to-use ultrapure, particle-free rinsing water

Gravimetric Dose Accuracy Assessment

The accuracy of drug delivery devices is critical to patient safety. Guaranteeing correct delivery dosage is obligatory for drug delivery systems like insulin-pumps, drug-eluting stents or intrauterine devices (IUD). To avoid failures or variations resulting in over- or under-dosing, you must check whether the drug is applied at constant rates over time. 

Our weighing solutions are best in class for medical device measurement accuracy for the critical parameters of flow, mass or volume over time:

  • Determine weight of smallest sample amounts with highest precision
  • Ensure and check exact drug uptake on device
  • Fastest stabilization means higher throughput, even in unstable environments

Keep Your Microbiological Limits Under Control

Airborne microbes pose a risk of contamination for products and raw materials. Continuous monitoring is a must to evaluate the microbial flora at your manufacturing facility for deviations from norm or undesirable organisms. For clarifying investigations, the verifiable avoidance of product contamination and reliable microbial identification are crucial.

Sartorius’ secure and flexible technology for air sampling by filtration enables accurate and reliable analysis – without the risk of cross-contamination by changing agar plates:

  • Be prepared for GMP Annex 1 regulations 
  • Continuous sample collection with just one filter
  • Less intervention/risk of secondary contamination 
  • Save time (no more frequent changing of agar plates) 
  • Retain smallest airborne micro-organisms at the most accurate level 
  • Water-soluble filters assure the best recovery of trapped microorganisms
  • Pair traditional growth-based methods with rapid detection methods
