Pharmacology of Lignocaine and Bupivacaine

This topic offers an in-depth comparative study of two cornerstone amide local anaesthetics: Lignocaine (Lidocaine) and Bupivacaine. As a tertiary student in Zambia, you will learn their pharmacokinetic properties (onset, duration, protein binding), maximum safe doses (with and without adrenaline), clinical preparations, and specific uses in spinal anaesthesia. Understanding the differences—such as Lignocaine's faster onset and Bupivacaine's longer duration and higher cardiotoxicity—is vital for drug selection in various surgical and procedural contexts. This knowledge is directly tested in medical, pharmacy, and nursing degree examinations across Zambian universities and is fundamental for safe prescription and administration. Mastery of this topic ensures you can optimize anaesthetic plans, minimize toxicity risks, and provide effective analgesia, contributing to improved patient outcomes in operating theatres and clinics throughout Zambia.
