Nasal Delivery

Nasal drug delivery has been in use for many years, primarily for the delivery of small molecules for use in respiratory and allergic rhinitis. Nasal drug delivery offers an alternative route of administration over injection.

Solutions for Nasal Delivery:

METHOCEL™ Cellulose Ethers have unique capabilities to control solution viscosity, direct drug spray pattern and retain drug on the mucosa to allow for permeation. These are key requirements for the deposition and delivery of small molecules & biologics.

POLYOX™ resins offers a number of important properties for mucoadhesion, including water solubility, hydrophilicity, high molecular weight, hydrogen bonding functionality, and good biocompatibility. Their long linear chain structure helps them to form a strong interpenetrating network with mucus. The polymer can be used in nasal solution applications.

Immediate Release - Liquids and Suspensions

Suspensions are pharmaceutically stable dispersions of an insoluble or sparingly-soluble drug in a liquid vehicle, usually an aqueous solution. They can be ready-to-use or reconstitutable, where the drug is mixed with other ingredients in the dry state and reconstituted with water at the time of dispensing to the patient.
