The Vital Role of Freeze Drying in Advancing Pharmaceutical Research

 

The pharmaceutical industry depends on the accuracy of information related to all those structures that are to be targeted for research. When studying an organism or sample that is to be prepared for analysis, retaining its integrity is one of the most vital steps. Moreover, the industry also requires drugs that are relatively easy in terms of storage and transportation and reduce the risk of degradation. One of the most suitable methods that play a crucial role in advancing pharmaceutical research and storage of drugs is freeze drying.

Understanding the freeze drying process

The freeze dryer equipment conducts the freezing and drying process in three different steps:

• Freezing

In this stage, the pharmaceutical product undergoes freezing only to convert water into ice.

• Sublimation

During sublimation, the ice is removed by converting solid ice into vapor under reduced pressure conditions.

• Desorption

In the final stage, traces of residual moisture undergo removal, thereby making the product stable and long-lasting.

By using the freeze dryer, you can make the final product porous that can be easily reconstituted with a solvent, usually water prior to use. This technology is especially useful for those drugs that are heat-sensitive and tend to degrade under the impact of conventional drying or other methods of storage.

Significance of freeze drying for pharmaceutical research

Here are the reasons why freeze drying is important for pharmaceutical research:

1. Increases stability of vaccines and biologics

Several of the modern-day drugs are made using complex molecules that are derived from living organisms like antibodies, nucleic acids, and proteins. Now, these molecules are extremely sensitive to humidity, temperature, as well as light, making it challenging for researchers to preserve the products.

Fortunately, the freeze drying techniques helps stabilize these substances without compromising their structural integrity. The freeze dryer also assists in the preservation of vaccines at ambient temperatures inside the refrigerator, making them more accessible in low-resource settings.

2. Retaining the efficacy and potency of drugs

If you have been researching in the pharmaceutical laboratory, you must be familiar that several of the active pharmaceutical ingredients or APIs tend to lose their potency and efficacy when the moisture and temperature levels are high. Freeze drying helps preserve the therapeutic content of the sensitive compounds like enzymes, peptides, and the monoclonal antibodies. That way, administering effective treatment becomes easy even when the drugs remain in the storage for longer hours.

3. Increases shelf-life of drugs

One of the most noted benefits of using a freeze dryer in the pharmaceutical laboratory is boosting the shelf life of various drugs. The absence of water prevents degradation reactions like hydrolysis and oxidation. Due to this, the freeze-dried pharmaceutical products remain intact and stable for many years when stored properly. That way the efficiency of pharmaceutical supply chains improve radically.

4. Aids delivery and reconstitution of drugs

Freeze-dried products are compact and lightweight. Therefore, it helps prevent the hassles of transportation and storage. Moreover, the reconstitution is easy and simple during the time of administering the drugs. This technique is especially useful for handling medical situations in areas where healthcare infrastructure is limited.

Applications of freeze drying process in drug development

What are the applications of freeze drying process in drug development? Here is what you need to know:

• Pace up research timelines

During the initial stage of drug discovery, researchers tend to work with extremely little quantities of valuable compounds that are also rare. With freeze drying, sample preparation becomes safe and effective, reducing the chances of loss and degradation. It helps in expediting pre-clinical studies and helps in spotting candidates for trial.

• Improve drug stability

The freeze dryer equipment allows researchers to experiment with multiple formulations, thereby enhancing stability and delivery. Researchers can optimize characteristics of various products like the rate of dissolution, solubility, and mechanical integrity by understanding the behavior of products during the freeze-drying cycle.

• Assist in clinical trials

During the procedure of clinical trials ensuring the stability of drugs that are to undergo investigation is important. With freeze-dried formulations, you will come across a reliable way to ensure consistency in the trial sites.

With continued efforts of innovation, the demand for freeze dryer is likely to grow. It is not just another technique of preservation but a milestone technique that is going to enable pharmaceutical research and innovation. As research procedures push ahead of restrictions, freeze-drying or lypholization is one of the trustworthy procedures that will expectedly enhance good health.
