Nasal Delivery System Overview
Nasal spray delivery systems for peptides consist of a container (vial or cartridge), a pump actuator, and a nasal applicator tip. The system design determines fill volume, dose per actuation, and compatibility with the peptide formulation. ShiLai™ Healthcare supports OEM partners in selecting and developing appropriate nasal spray delivery systems for their research supply programmes.
All nasal spray delivery systems are provided in a research and OEM development context. No therapeutic claims are made regarding efficacy, absorption, or clinical outcomes.
Available Delivery Formats
Single-Chamber Nasal Spray
Standard single-chamber nasal spray format for stable aqueous peptide solutions. Compatible with conventional nasal pump actuators used in research supply contexts.
- Aqueous peptide solution
- Standard nasal pump actuator
- Multi-dose or unit-dose formats
- Custom fill volume on enquiry
Dual-Chamber Nasal Spray
Dual-chamber format separating lyophilized peptide from solvent until point of use. Suitable for peptides with limited aqueous stability.
- Lyophilized peptide + solvent
- Mixing at point of use
- Reduced degradation risk
- Custom chamber volumes on enquiry
Device Compatibility
Nasal spray device compatibility is assessed on a per-project basis. Key parameters include container neck finish, pump stroke volume, actuator orifice diameter, and formulation viscosity. We work with standard nasal spray device formats used in research supply and can advise on device selection during the OEM development process.
Formulation and Development Support
Formulation support for nasal spray peptide projects includes buffer system selection, pH range assessment, preservative considerations, and isotonicity adjustment. Stability assessment support is available as part of the OEM development workflow.
View OEM Development Programme →Prototype and Compatibility Testing
Prototype development for nasal spray delivery systems involves assembling the container, pump actuator, and nasal tip in the intended configuration and evaluating compatibility under defined test conditions. Compatibility testing covers container-closure integrity, spray pattern, dose uniformity, and formulation-device interaction. All testing is conducted in a development context; results are specific to the tested configuration and conditions.
B2B Development Workflow
Nasal spray delivery system development follows a structured B2B project workflow:
- Project brief and molecule review
- Device and cartridge format assessment
- Formulation-container compatibility evaluation
- Prototype assembly and initial testing
- Stability and performance evaluation
- Packaging and documentation finalisation
Workflow stages and timelines are defined per project. No guaranteed outcomes are implied.
