Compare and contrast the mechanism of action, pharmacokinetics and central nervous system
effects of morphine and tramadol.
In general candidates either lacked a depth of knowledge, or a deep enough understanding of the drugs so as to apply their knowledge specifically to the central nervous system (CNS). Mechanism of action and pharmacokinetics for morphine was better understood, in comparison to tramadol. Mention of the non-CNS effects of morphine and tramadol, was not expected, did not score marks, and would have wasted valuable exam time.
