Q

Succinylcholine

A

Depolarizing neuromuscular blocker. Blocks ganglionic nicotinic receptors by desensitizing (overstimulating?) - fast acting, get initial twitching before paralysis -rapid onset (30sec) but very short duration of action (5–10 min); agonist at nicotinic ACh receptors, depolarizes the muscle fiber (similar to ACh), but in a biphasic manner: – Phase I (depolarizing phase) muscle twitches occur while depolarizing the muscle fibers. – Phase II (desensitizing phase) aqer sufficient depolarization has occurred the muscle is no longer responsive to ACh released by the motor neurons. At this point, full neuromuscular block (paralysis) has been achieved. • Effects are sustained under the influence of AChE inhibitor.(not reverse by administering the AChE inhibitor) • Adverse effects: Postoperative myalgia and fatigue, arrhythmia, hyperkalemia (burn patients), increased ocular pressure, increased risk of regurgitation/aspiration (obese patients, diabetic patients). – Rare, inheritable risk for interaction with volatile anesthetics causing malignant hyperthermia (abnormal release of Ca2+ from skeletal muscle stores.) – Treated with dantrolene.

Q

A

Antibiotics for Acne Vulgaris.
