CD Formulation has revolutionized the process of microsphere stability testing, making quality control easier and more efficient. In the pharmaceutical industry, ensuring the stability of drug formulations is of paramount importance to guarantee their efficacy and safety. CD Formulation is a leading company in the field of drug formulation development and manufacturing.

Stability of microspheres is a critical factor

Microspheres, tiny spherical particles containing active pharmaceutical ingredients, have gained immense popularity in drug delivery systems. However, the stability of these microspheres is a critical factor in determining the efficacy and shelf life of formulated drugs. Recognizing the need for a reliable stability testing method, CD Formulation has developed state-of-the-art solutions.

‚ÄúTraditionally, stability testing methods often involve complex and time-consuming procedures, making the process cumbersome for pharmaceutical companies. Our microsphere stability testing, on the other hand, offers a streamlined and user-friendly approach that saves both time and resources,” said CD Formulation’s Marketing Director.

In general, items to be tested in a microsphere stability testing project are:

  • Organic solvent resistance
  • Acid resistance
  • Alkaline resistance
  • Accelerated experiment
  • Stability analysis of microspheres


One of the key advantages of CD Formulation’s stability analysis is its non-destructive nature. By utilizing state-of-the-art analytical techniques, such as high-performance liquid chromatography (HPLC), gas chromatography (GC), and mass spectrometry (MS), the company can study the stability of microspheres without altering or damaging the samples. This ensures that the integrity of drug formulations is maintained while providing accurate and reliable data.

In addition, CD Formulation’s stability testing process follows rigorous industry standards and guidelines. The company’s highly trained team of experts performs accelerated stability testing by exposing microspheres to various environmental conditions to simulate real-life scenarios. By exposing samples to stressors such as temperature, humidity and light, CD Formulation can accurately assess degradation and potential changes in formulations.

Precise and consistent monitoring of critical parameters

The company’s advanced stability testing equipment enables precise and consistent monitoring of critical parameters such as drug release, particle size and physical properties. This technology-driven approach ensures that pharmaceutical companies can confidently evaluate and optimize their drug formulations for improved stability and product performance.

Post-manufacturing stability analysis

CD Formulation not only offers stability testing for microspheres during development, but also provides post-manufacturing stability analysis. This comprehensive approach allows pharmaceutical companies to monitor the long-term stability of their products, ensuring consistent quality throughout their shelf life.

As the pharmaceutical industry continues to expand and evolve, CD Formulation’s microsphere stability testing has become an essential tool for quality control. “We can assess not only microspheres, but also microneedles. Based on the different types of microneedles, the corresponding experimental design will be different. Our solid microneedle technology also proves to be popular among our customers,” the director added.
