A revision guide for pharmaceutical rheology to help you score top marks (MPharm or PharmD)

Rheology is a difficult subject! So what should you know in order to answer a question on rheology in a pharmacy exam? Here we review the key things you need to know to pass your exam!
- How to define Newtonian and non-Newtonian materials
- Shear-thinning materials (plastic and pseudoplastic behaviour)
- Shear-thickening materials (dilatant behaviour)
- Time-dependency (thixotropy and rheopexy)
- Formulation aspects

Hey! Love your videos - they've been super helpful. Just wanted to point something out about this one. In my textbook (Martin's Physical Pharmacy), the graphs for plastic/pseudoplastic flow and dilatant flow seem to be swapped compared to what you showed. Could you double-check? It's possible I'm misunderstanding, but just wanted to flag it. Thanks a bunch!

Nevermind! I just realized that my book has the axis's swapped. LMAO.

Thank you for your kind words - I will indeed check but the most likely scenario is that the axes are plotted the other way round (I have shear rate on the x-axis and shear stress on the y-axis) and the graphs will look different if these are swapped round.

Ah ha! I should have read ALL the comments before starting to reply!
