At Nanopharm, we specialize in developing liquid nasal spray products that can reliably deliver precise drug doses to patients.  We assess liquid formulation parameters such as pH, buffer selection and drug stabilizing excipients to create stable formulations suitable for intranasal drug delivery. Nanopharm scientists are also experienced in reformulating marketed drugs into a nasal spray format.  Such reformulations can require changes in pH, viscosity or the addition of formulation modifiers to become a stable liquid formulation that can meet the desired intranasal drug delivery performance parameters. Nanopharm’s experienced formulators control rheological properties, such as viscosity, as they can directly impact spray characteristics like droplet size and spray pattern. These parameters can be optimized for the specific nasal spray device, defining broad or targeted coverage impacting drug deposition in target regions.  Nanopharm scientists use different excipients and mucoadhesives to control residence time, ensuring the drug is delivered to the target location in the nasal cavity and that it is resident long enough to be absorbed. With our specialized analytical tools and formulation approaches, we are ideally positioned to develop robust nasal spray drug products.
