The nose-brain route provides an alternative non-invasive route for delivering protein/peptide macromolecule drugs. With decades of experience in protein/peptide nasal formulations and expertise in delivery, CD Formulation can help you overcome the development challenges of any protein/peptide nasal solution, protein/peptide suspension, and protein/peptide dry powder formulations, providing the key performance and quality testing required for successful product development. Our scientists optimize the performance and quality of nasal drugs through formulation, stability, testing, and in vitro bioequivalence study services. We develop safe and reliable drugs through strategic formulation and comprehensive analytical testing.
The nasal route of administration has emerged as a promising strategy for protein/peptide delivery. Compared with other delivery routes, nasal administration has the following advantages:
With decades of experience supporting protein/peptide inhalation therapy development for clients around the world, our experts provide one-stop formulation development, product characterization studies, method development and validation, inhalation product analysis and testing, and preclinical manufacturing services.
Our comprehensive protein/peptide nasal inhalation product development services and unique project management approach enable you to achieve rapid success and help you accelerate product launches.
Protein/peptide nasal inhalation formulations The low permeability of the nasal mucosa and the clearance of nasal cilia hinder the absorption of protein/peptide drugs through the nasal cavity. Our formulation scientists deploy a series of formulation strategies to increase the residence time of proteins/peptides in the nasal cavity, thereby promoting the absorption of protein/peptide drugs, including:

Our formulation team will customize the above formulation development strategies to meet your product delivery needs - for example, designing and developing spray freeze-dried polymer liposomes to enhance nasal mucosal absorption.
All of our protein/peptide nasal delivery system development services are performed in Good Manufacturing Practice (GMP) compliant laboratories and include comprehensive formulation development and scale-up, device screening, accelerated stability studies, clinical supply manufacturing, and comprehensive CMC support to help you optimize the performance of your protein/peptide nasal drug in aqueous, powder or propellant-driven form.
Our expertise covers:
Nasal delivery is typically supplied as a nasal aerosol product that produces droplets in the 20-200 micron range when administered. Regulatory requirements necessitate the characterization of nasal biologics in accordance with ICH Q6B and EMA drug quality guidance for inhaled and nasal products.
We continually invest in cutting-edge nasal drug product equipment and use current industry-standard nasal drug product analytical testing techniques to support the characterization of protein/peptide nasal delivery systems with support in the following aspects:
A solution containing protein/peptide active drug molecules can be spray-dried in one step to obtain dry fine powder. This technology is suitable for organic and water-soluble drugs, but not for heat-sensitive proteins/peptides.
A solution containing protein/peptide active drug molecules is first atomized into a refrigerant (usually liquid nitrogen) and then freeze-dried. This technology is suitable for thermosensitive formulations that are not suitable for spray drying. SFD particles usually have a porous structure and good aerosol properties, making them particularly suitable for inhalation.
A solution containing protein/peptide active drug molecules is dissolved in a supercritical fluid (SF). The rapid expansion of the SF solution causes rapid nucleation of the solute, producing very fine micronized particles. SF powder is spherical, uniform in shape, and smooth in surface.

Results:
The authors developed a new nasal carrier, phospholipid magnets, for enhanced drug delivery to the brain. The system contained soft phospholipid vesicles composed of phospholipids, water, propylene glycol, magnesium salts, and the mucoadhesive polymer alginate. The ability of the carrier vesicles to capture various molecules was evaluated by CLSM and ultracentrifugation combined with HPLC. The mucoadhesiveness of the carrier was tested in vitro using porcine nasal mucosa. The delivery of rhodamine 6G, insulin, and epidermal growth factor was estimated by two methods, multiphoton microscopy and near-infrared (NIR) imaging. The results showed that the system, composed of soft multilayer nanovesicles, was able to capture both lipophilic and hydrophilic molecules. The contact time of the drug with the nasal mucosa was prolonged. This suggests that the phospholipid magnesium salt nasal carrier is able to enhance absorption by prolonging the mucosal contact time.
