Lyophilization Contract Manufacturing Services: What to Know

Lyophilization contract manufacturing services are beneficial for pharmaceutical and biopharmaceutical companies who lack the necessary resources and expertise to produce their own lyophilized products. Lyophilization is a meticulous process, but with experienced professionals to help guide the way, an effective lyophilized drug can be produced in a short amount of time. When outsourcing this delicate procedure, there are a few key factors to consider to find the best possible match for your drug development project.

 

In this article, we'll discuss the basics of lyophilization in the pharmaceutical industry, along with tips on how to select a contract development and manufacturing organization (CDMO) for lyophilization outsourcing. 

What Is Lyophilization?

Lyophilization is a process that removes moisture from a product while preserving its original chemical properties. Also known as freeze drying, this process is used in the production of many products, such as pharmaceuticals, biologics, food additives, and nutraceuticals. Lyophilization helps to reduce spoilage and extend the shelf life of a product, making it more stable and easier to transport.

 

Pharmaceutical companies use lyophilization to make lyophilized injections, eye drops, other sensitive drugs, and parenteral dosage forms that cannot be manufactured through traditional methods. In the biopharmaceutical industry, lyophilization is used to preserve proteins and peptides for long-term storage, giving unstable biologics the shelf life and stability for more widespread distribution and use.

How Drugs Are Lyophilized

Naturally, the process of lyophilization in the pharmaceutical industry is quite different from freeze drying foods and other consumer products. Here's a step-by-step overview of how lyophilized drugs are made:

 

During the secondary drying stage, which is sometimes referred to as desorption, the product is exposed to a cold temperature and low pressure. This helps push any residual water molecules out.1. Freezing

Also known as pre-drying, during this step the product is mixed with an excipient before being frozen in vials or containers. The excipient helps to absorb moisture and stabilize the product during lyophilization.

2. Primary Drying

The frozen product is placed inside a vacuum chamber and sublimated, transforming the solid directly into a gas without passing through a liquid phase. This step is also known as sublimation.

3. Secondary Drying

During this stage, which is sometimes referred to as desorption, the product is exposed to a cold temperature and low pressure. This helps push any residual water molecules out. 

4. Analysis

The lyophilized drug is tested to ensure its stability, dose uniformity, sterility, and quality. This is accomplished through a variety of methods, including spectroscopy and chromatography.

 5. Packaging

Lyophilized drugs must be packaged in an air-tight aseptic container to prevent moisture from entering.

Benefits of Lyophilization

There are many reasons why lyophilization is being increasingly used in the development of drugs, including parenteral, and biologics. 

Reliability

Lyophilization is a reliable, efficient, and cost-effective method of manufacturing drugs. The process ensures that the product is stable, can be stored at room temperature, and has an extended shelf life. 

Storage

Lyophilized products last longer than liquid or air-dried versions because they are completely insulated in a vacuum-sealed environment, eliminating the risk of dehydration or contamination. Shelf life is optimized with lyophilization, improving the product's long-term stability and transportability.

Cost Savings

Lyophilization is much less expensive than many other drug production approaches, making it a cost-effective solution for many companies. By outsourcing lyophilization services to a contract manufacturer, companies can save money by avoiding costly equipment purchases and greatly reduce labor costs associated with manpower.

Ease

Additionally, lyophilization is a fast, easy process with minimal equipment required. Lyophilized products can be stored in ready-to-use form and reconstituted quickly when needed for use in medical or clinical settings. This eliminates the need for cold storage, making it an ideal option for shipping or storing drugs that are unstable in other forms.

Examples of Lyophilized Products

Pharmaceutical products that can be produced through lyophilization include:

 

  • Vaccines –  Vaccines are commonly lyophilized to preserve potency and extend shelf life.
  • Antibiotics – Lyophilization is often used for antibiotics, as it eliminates the need for preservatives and keeps them in a stable state.
  • Hormones – Hormonal drugs are easily stabilized with lyophilization, making them easier to transport.
  • Proteins –  Proteins can be preserved and released in a controlled manner using lyophilization methods. 
  • Peptides – Peptides are highly sensitive to their environment, so lyophilization is often used to ensure product stability and effectiveness. 
  • Enzymes –  Enzymes can be effectively stabilized and preserved through common lyophilization methods.

 

Lyophilized products are also used to produce drugs that are easier to store and administer. For example, injectable insulin has been freeze-dried for ease of use, enhanced pulmonary delivery, and improved storage.

Lyophilization Cycle Development

Once a product has been identified as requiring lyophilization, the next step is to develop the specific cycle that will be used in its production. This includes the temperature and pressure settings, as well as the duration of each stage.

 

The process of lyophilization can be optimized to improve the performance and stability of the end product. Lyophilization optimization involves testing different parameters, such as temperature, pressure, and duration, to find the ideal combination that results in the highest quality final productThe process of lyophilization can be optimized to improve the performance and stability of the end product. Lyophilization optimization involves testing different parameters, such as temperature, pressure, and duration, to find the ideal combination that results in the highest quality final product. The right lyophilization partner will have the necessary knowledge and expertise to develop a lyophilization cycle suitable for a particular drug, which is why it’s imperative to choose your outsourcing partner wisely.

 

An example of lyophilization optimization is increasing the temperature of the product during the process to reduce cycle time and improve product stability. (Note: As a provider of lyophilization services, Ascendia Pharmaceuticals can help optimization by testing different parameters, providing valuable insight into what works best for your particular product.)

 

In addition to developing the cycle, the right provider will also house the necessary equipment to perform the process. This includes freeze dryers, which use a combination of reduced temperature and pressure to remove moisture from the product. Other items, such as cold traps, vacuum pumps, and temperature controllers, may also be necessary for the lyophilization process.
