Pancuronium (Pavulon) is a competitive acetylcholine antagonist with an IC50 of 5.5 ?0.5 nM.It is a typical non-depolarizing curare-mimetic muscle relaxant. It acts as a competitive acetylcholine antagonist on neuromuscular junctions, displacing acetylcholine (hence competitive) from its post-synaptic nicotinic acetylcholine receptors. It is (unlike suxamethonium) a non-depolarizing agent, which means that it causes no spontaneous depolarizations upon association with the nicotinic receptor in neuromuscular junction, thus producing no muscle fasciculations upon administration.

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
