CD Formulation is one of the leaders in developing innovative drug delivery systems for proteins/peptides. We excel in encapsulating proteins/peptides in various excellent drug carriers to improve their stability, solubility, and bioavailability. With advanced technology and a professional team, we provide customers with customized solutions, including but not limited to nanoparticles, liposomes, microcapsules, hydrogels and other delivery systems.
Therapeutic proteins and peptides have become a hot topic in recent years due to their high efficacy and few side effects. However, these active drug molecules are relatively unstable and have limited permeability to the epithelium and gastrointestinal tract. The most commonly used method of administering protein/peptide compounds is parenteral delivery in liquid form. However, protein drugs administered by these routes have low bioavailability because they are rapidly eliminated from circulation through renal filtration and enzymatic degradation. Therefore, designing new drug delivery systems has become critical to the success of such active drug molecules, which can help:
Encapsulation of proteins/peptides into micro- or nano-carriers is a promising approach to enhance the stability of therapeutic peptides and proteins, which can protect drugs from the harsh environment in the body, deliver protein/peptide drugs to specific target sites, and release from particles by diffusion, swelling, erosion, or degradation.
At CD Formulation, our formulation scientists are adept at using a variety of innovative drug carriers, such as nanoparticles, polymer nanoparticles, liposomes, hydrogels, microemulsions, etc. to deliver your proteins and peptides. These drug carriers have different properties that can help enhance the solubility, stability, and bioavailability of your therapeutic proteins/peptides, thereby improving drug efficacy and reducing dosage.
Importantly, our formulation scientists can also customize specific drug carriers according to your needs to ensure optimal drug delivery and stability.
In addition to drug carrier selection, our team of formulation scientists focuses on continuous innovation and optimization of formulation technology to improve the stability and bioavailability of proteins and peptides. The best delivery effect is achieved by systematically optimizing different formulation parameters, including the ratio of drug and carrier, solvent selection, pH value, temperature, etc. Rigorous stability testing is performed to ensure that the formulation does not lose activity during long-term storage and use.
We offer the following innovative drug delivery system development services for your proteins and peptides:

Results:
The authors developed a chitosan (CS)-coated cationic liposome for oral administration of insulin. The performance of CS-coated liposomes and uncoated liposomes was examined by in vitro, ex vivo, and in vivo studies in streptozotocin-induced diabetic mice. The results showed that the nanosize of CS-coated liposomes was 439.0±12.3 nm, the Zeta potential ( +60.5 ± 1.9 mV) was significantly reduced, and it had a high encapsulation efficiency. The tissue residence time of CS-coated liposomes was increased. The blood glucose of mice orally administered with CS-coated liposomes was significantly reduced and maintained for up to 8 hours. This indicates that CS-coated insulin-loaded cationic liposomes improve drug loading efficiency and are expected to prolong the hypoglycemic pharmacological effect.
