Solubility Improvement and Bioavailability Enhancement Services

Bioavailability refers to the degree and speed at which a drug is absorbed into the blood circulation. There are ongoing challenges with poorly water-soluble drugs and have failed to reach the market due to their poor water solubility. CD Formulation has developed a range of technologies and formulation expertise to improve the solubility and bioavailability of these drugs, helping customers find the right way to commercialize their drug products. This experience, along with a variety of techniques, enables CD Formulation to overcome many of the hurdles surrounding solubility and bioavailability, including physical, chemical, encapsulation techniques and so on.

Our Services

Every formulation is unique, just as every drug candidate is unique. We always keep in mind the target product profile and the final desired dosage form, so as the molecule progresses through the development process, the drug product strategy is robust with a scalable process to avoid any delays later in development. Our goal is to optimally match technologies that enhance drug solubility and bioavailability with our clients' corporate goals, timelines and budgets. Services we provide include:

• API Physical Modification Services
• API Chemical Modification Services
• Encapsulation Techniques Services
• Cyclodextrin (β-CD) Inclusion Complex Services
• Make Phospholipid Complex Services
• Self-emulsifying Drug Delivery System Services
• Bioavailability/Bioequivalence Detection

Our CD Formulation team is a leading expert in all aspects of pharmaceutical formulation development and dosage form optimization, providing you with a one-stop shop where we can improve drug bioavailability and solubility based on API characteristics and customer development goals. If you have poorly soluble or insoluble drugs, please contact our staff and we will determine the most appropriate way to assist your drug development.
