Dosage Forms

Is your viscometer approaching the end of its life? Are you starting to feel that your trial and error, ‘rheology-light’ approach to formulation is becoming dated? Or are there longstanding product performance issues that you’re failing to gain traction with, where you suspect rheology may hold the answer? 

Dry powder inhalers are accepted as being complex drug products due to the interactions which occur between the active pharmaceutical ingredients (APIs) and excipients within the formulation and the way this then affects the efficiency of drug delivery by the inhaler device. Obtaining component specific particle size and particle shape distribution data can help with understanding the properties of the formulation as part of formulation or deformulation studies. This application note describes how the combination of automated image analysis with Raman spectroscopy in the Morphologi G3-ID allows the individual components present within a dry powder inhaler formulations to be independently characterized and compared.

Tablets are the most common dosage form, but have you considered all of your options?

This article explains how an inline probe was used to monitor a granulation at three different scales to confirm that, in each case, the granules produced were the same size, and more importantly produced tablets of identical quality as quantified by hardness.

Sitting Down With… Akm Khairuzzaman, a 3D printing expert from the FDA.

In this article, triple detection SEC and MDRS are considered within the context of characterizing complex drug formulations, with specific case studies and results illustrating their application.

This article explains how dynamic light scattering (DLS) can be used to gather particle size distribution data for the successful use of nanosized colloidal gold in drug delivery applications.

Nominations for the 2017 Power List are now open and will close on February 1, 2017.

Automated image analysis has been combined with Raman spectroscopy to achieve component-specific size and shape analysis of active ingredients, supporting and accelerating the commercialization of both innovator and generic pharmaceutical products.
