Refer to the following diagram representing the shear stress-shear rate rheogram for an IM oily injection formulation and then answer the following questions:

a) Describe and explain the rheological behaviour seen at different shear rates. [2 marks]

b)If the formulation is to be injected through a hypodermic needle, comment on the possibility of the formulation experiencing any difficulty or the oily formulation becomes jammed during injection (the formulation syringeability and injectability) [2 marks]
