Evaluating Quality Control Solutions for Parenteral Products

Evaluating Quality Control Solutions for Parenteral Products

Parenteral preparations are defined as solutions, suspensions, emulsions for injection or infusion, powders for injection or infusion, gels for injection and implants. They are sterile products intended to be administrated directly into human bodies. Parenteral drug products are expected to be free from microorganisms, pyrogenic substances as well as other visible particles. Contaminated parenteral drug products can cause serious health concerns to the patient. Hence, sterility assurance and package integrity testing are of paramount importance in parenteral drug manufacturing. Read on to know more about parenteral products package testing methods offered by PTI.

Parenteral products package testing methods:

1. Vacuum Decay technology

Vacuum Decay technology is a non-destructive Container Closure Integrity test method primarily used to detect leaks in package seals. Proven to be the most practical and sensitive vacuum-based leak test method, Vacuum Decay technology is capable of identifying leaks in sealed rigid, semi-rigid and flexible packaging made of non-porous or porous materials. It provides reliable, accurate and repeatable test results that ensure deterministic package testing and leak detection. Vacuum Decay technology has established itself as a non-destructive alternative to traditional test methods like Water Bath and Dye Ingress, making it a practical solution for leak detection in the Pharmaceutical and Medical Device industry.

How does Vacuum Decay technology work?

The principle behind Vacuum Decay technology is simple and it challenges container integrity based on fundamental physical properties. The test begins by placing sample packages in a closely fitting evacuation test chamber, which is equipped with an external vacuum source. Based on the test sample and level of sensitivity required, a pre-determined vacuum level is chosen for the test. The next step involves evaluating the test chamber and test system dead space for a pre-determined period. Differential pressure transducers are used to monitor changes in vacuum levels for a specified period. A pressure increase beyond the predetermined pass/fail limit indicates container leakage.

Role of MicroCurrent HVLD Technology in Parenteral Product Container Closure Integrity (CCI) Testing

Role of MicroCurrent HVLD Technology in parenteral product container closure integrity (CCI) testing

Ensuring pharmaceutical package integrity has always been a priority for drug product manufacturers. However, over the past few decades, innovations in health care sector have also accelerated pharmaceutical package integrity challenges. Although testing package quality of all healthcare products is important, in the case of parenteral products it is amplified significantly. Parenteral products are defined as injectible products that can be either liquid or powders. Solutions can contain suspensions, emulsions and be proteinaceous in nature. ”. Since these drugs are directly administered into human bodies, ensuring complete integrity of such packages is crucial. Common packaging formats for parenteral products include Liquid-filled containers such as vials, ampoules, syringes, BFS and auto injectors; Lypholized (powder) products are often packaged in vials. Even a minute breach in the package can cause microbial contamination leading to product deterioration. Hence ensuring container closure integrity is a critical process in the life cycle of parenteral products.

What is HVLD Methodology?

High Voltage Leak Detection (HVLD)) is a non-destructive Container Closure Integrity technique used primarily to evaluate closure integrity of parenteral product packaging. HVLD technology makes use of quantitative electrical conductivity measurement principles. This method operates by passing high voltage micro current signals through sample packages. Under the presence of a leak, the electrical resistance of the sample declines, causing an increase in current. Applications of High Voltage Leak Detection Technology include testing of the following package formats:

  • Pre-filled Syringes
  • Ampoules
  • Drug Product Cartridges
  • Liquid Filled Vials
  • Blow-Fill-Seal (BFS) Container

PTI’S MicroCurrent HVLD technology has revolutionized the conventional HVLD method. MicroCurrent HVLD is a non-destructive, non-invasive CCI technique that can be applied to a wide range of liquid filled products including low conductivity sterile water for injection (WFI) and highly proteinaceous drug products within suspensions. PTI’s E-scan HVLD, a highly sensitive CCI testing process uses electrode probes to scan sealed non-conductive containers. Under the presence of a leak, there will be a change in current flow indicating a defect in the container along with its approximate location. This unique technique uses about 50% less voltage and exposes the product and environment to less than 5% of the voltage. An important feature of E-scan HVLD is its ability to easily shift from the laboratory offline to 100% inline testing applications. With the capability to accommodate multiple packaging formats including glass, plastic or poly laminates, it is an ideal solution for parenteral package testing.

Benefits of MicroCurrent HVLD:

  • Deterministic, non-destructive, non-invasive
  • High level of repeatability and accuracy

CCIT - A risk mitigation tool for parenteral products

CCIT - A risk mitigation tool for parenteral products

Today’s healthcare industry assures treatments that were unimaginable a few years ago. As pharmaceutical industry grows in importance, the techniques of primary packaging for healthcare products, especially parenteral products has taken on new prominence. Common parenteral packaging methods include Liquid-filled containers such as vials, ampoules, syringes, blow-fill-seals and auto-injectors and containers filled with lyophilized products. Since these drugs are directly administered into human bodies, high sensitivity integrity tests are required to ensure product quality throughout its shelf life. For reasons of safety, packaging material, integrity and design are regulated by Food And Drug Administration as strictly as the product itself.

Container Closure Integrity Testing is a leak detection test conducted using a non-destructive packaging inspection system to protect the drug from any possible contamination. It is a crucial step in evaluating safety and integrity of the primary packaging so as to maintain a sterile barrier and to avoid leakage resulting in contamination of the drug. Packaging components like bottles, vials, syringes that are in direct contact with the product are called primary components while aluminum caps, cardboard boxes are secondary components as they are not in direct contact with the product. Proper packaging should be a priority for all drug products, but in case of parenteral products, these concerns amplifies several folds as they are directly injected. Hence initiating a proper container closure system is vital for product and consumer safety.

Although Container Closure Integrity Testing can be performed in many different ways, it can be broadly classified into Probabilistic methods and Deterministic methods. Probabilistic test methods including Microbial Challenge by Immersion, Tracer Liquid Tests (e.g. Dye Ingress), Bubble Tests etc. are traditional test methods where result accuracy may be uncertain. On the other hand, Deterministic test methods like Electrical Conductivity and Capacitance Test (HVLD), Laser-based Gas Headspace Analysis, Mass Extraction, Pressure Decay provide quantitative results with high accuracy. The United States pharmacopeia released guidance in 2016 stating that deterministic methods are preferred over probabilistic test methods.Packaging Technologies And Inspection (PTI’s) Microcurrent HVLD technology and vacuum decay technology are the latest inventions in package integrity testing of parenteral products.

1. Microcurrent HVLD Technology: Microcurrent HVLD is a unique High Voltage Leak Detection Technology, highly effective across all parenteral products.
