Nasal Inhalation Delivery – An Introduction Guide
An introduction to nasal delivery The delivery of APIs via nasal inhalation is of growing interest to companies looking to exploit the benefits of this delivery route. Delivery targets are typically broken down into three categories Local delivery to the nasal membranes (e.g. for vaccines, antivirals, prophylactics) Systemic delivery by absorption into the bloodstream (e.g. […]
Nasally Delivered Dry Powder Dosage Forms: Particle Size Analysis
Introduction to Nasal Delivery The delivery of APIs via nasal inhalation is of growing interest to companies looking to exploit the benefits of this delivery route. Delivery targets are typically broken down into three categories Local delivery to the nasal membranes (e.g. for vaccines, antivirals, prophylactics) Systemic delivery by absorption into the bloodstream (e.g. for […]
In Vitro Testing of Dry Powder Nasal Delivery Devices
Successful nasal drug delivery of dry powder formulations requires a delivered dose that can penetrate beyond the nasal entrance region and deposit in the peripheral nasal cavity, whilst avoiding deeper penetration to the airways of the lungs. This delivery, or deposition pattern, is determined by the aerodynamic particle size of the powder exiting the device, […]
Characterising the Physical Properties of Spray Dried Powders
The Benefits of Powder Characterisation When developing products containing spray dried powders it is vital that the physical properties of the powders produced are determined. The physical properties of spray dried powders provides important information that can assist during the pre-formulation screening and early process development phases since these properties will have a direct impact […]
Using Spray Drying to Develop Inhaled Dosage Forms
Pulmonary delivery is showing increased popularity as a viable dosage form for treating local airway diseases and offers additional potential for systemic drug delivery. Within this space there are a number of delivery approaches that can be undertaken. These include dry powder inhaled formulations (DPI) and pressurised metered Dose Inhalers (pMDIs). Each of these delivery […]
Selecting a Spray Dryer for Development Studies and Clinical Manufacture
Loading the Elevenlabs Text to Speech AudioNative Player… Talk to our experts Virtual Facility Tour When customers initiate discussions with Upperton, one of the first questions we are asked is “which spray dryer(s) do you have and how much material can they produce?” Whilst these are very pertinent questions, the answer is not a simple […]

19th March 2019 – Engineered Powder for Enhanced Pulmonary Delivery Upperton is continuing to invest in its combined spray drying and micronisation technology in order to meet increased demand. This emerging processing technology has been developed to enable the production of larger quantities of engineered powder formulations suitable for pulmonary delivery. The expansion of this service has been […]
Analytical Techniques for Biotherapeutics
Analysing Biotherapeutic Formulations There is growing interest in the use of spray drying to create biotherapeutic dry powder formulations. Spray drying is becoming increasingly viewed as a more cost-effective method for enhancing the stability of thermo-sensitive molecules (such as proteins, peptides, monoclonal antibodies and vaccines). A key aspect in the successful development of dry powder formulations […]
