Custom Joint Carriers

The use of joint carriers can make up the deficiency of single carrier. For example, polyvinylpyrrolidone forms a gel when dissolved, which is not conducive to drug dissolution and utilization. When the carrier is used together, its dissolution behavior and stability will be improved. The combined support can be divided into binary solid dispersion and ternary solid dispersion.

CD Formulation has a professional team of chemists, pharmacists and highly qualified laboratory operators. They have expertise in drug formulation, pharmaceutical industry and contract service organizations. CD Formulation can be customized as a combined carrier to meet all customer needs. After receiving customers' orders, our experts will be at your service throughout the process to ensure that we provide customers with the most cost-effective and time-saving solutions.

Our Services

Most drugs have problems of poor solubility and low bioavailability before entering the market, and solid dispersion is a good solution to this problem. The carrier used in the solid dispersion is critical, where the combination carrier can combine the excellent performance of other carriers to improve drug bioavailability, solubility and stability. Our research team is dedicated to solving drug development problems for our clients, including customized combination vector services:

1. Make plans according to customer requirements. According to the basic efficacy of drugs, a series of suitable combination vectors were screened initially.

2. Layer upon layer screening, testing and selecting the most appropriate joint carrier, which can be binary, ternary or multivariate;

3. Repeat the experiment, optimize the material, finalize the final carrier, disperse the drug in the carrier, evaluate the effect of the drug, and send the test data to the customer.

We also have a very professional after-sales service, convenient for customers in any process of problems. If you have any questions about poorly soluble or insoluble drugs, please do not hesitate to contact us and we will provide you with the most professional service.
