This viva refers to Section A(i) and Section A(ii) of the 2017 CICM Primary Syllabus. Section A(i) reads cryptically "A more detailed knowledge would be expected for more commonly used drugs.", which is not a learning objective in any meaninful sense. But, something needed to be concocted to help prepare for possible future vivas.
Pharmaceutics is the study how to best present the pure drug molecule in order to achieve the therapeutic goal.
"Pharmaceutics... is the discipline of pharmacy that deals with the process of turning a new chemical entity (NCE) or old drugs into a medication to be used safely and effectively by patients. It is also called the science of dosage form design."
To determine how this could be happening, Shrank et al (2007) evaluated a pile of drug labels from pharmacy-dispensed preparations. The following issues were identified:
The Australian TGA has introduced new clearer labeling rules in 2016, as a legal act (Therapeutic Goods Order No. 91 - Standard for labels of prescription and related medicines.)
Excellent example of major packaging problems are drugs like sodium nitroprusside (which should not be exposed to light) and paraldehyde (which will happily dissolve its way out of any plastic container).
