Final answer:
The question seems to be incomplete, but I can provide some information related to dosing of medications based on weight and age.
Step-by-step explanation:
The question seems to be incomplete or has some typing errors. However, I can provide some information related to dosing of medications. IBW usually stands for Ideal Body Weight, which is used to calculate appropriate drug dosages based on a patient's weight. TBW might refer to Total Body Weight, which is another method for calculating drug dosages. Sux, on the other hand, might refer to Succinylcholine, a medication used in anesthesia. The dosing of Succinylcholine is based on factors like weight and age.
