Final answer:
The property not associated with lidocaine is muscle relaxation. Lidocaine is effectively used for local and topical anesthesia as well as having antiarrhythmic properties, due to its sodium channel blocking effect on neurons.
Step-by-step explanation:
The property of lidocaine that is NOT correct is C. Muscle relaxation. Lidocaine is known for its ability to provide local anesthesia and topical anesthesia, as it functions by blocking voltage-gated sodium channels on neurons. This action prevents the transmission of nerve impulses that would usually signal pain, hence providing an anesthetic effect. Blocking these sodium channels impedes the propagation of action potentials, leading to numbness in the area where lidocaine is applied. Furthermore, lidocaine also has antiarrhythmic action, as it can suppress abnormal heart rhythms by reducing the excitability of cardiac cells.
Understanding that lidocaine inhibits the influx of Na+ ions into neurons is key to recognizing why it doesn't induce muscle relaxation as its primary function. Instead, drugs like d-tubocurarine are used for muscle relaxation since they block the action of acetylcholine at neuromuscular junctions.
