Distribution- decreased circulation-less resources- need to start low and go slow from there
metabolism-lower metabolism, drugs don’t break down as fast and can sit in system for longer, more cause for adverse reactions due to drugs going where they aren’t supposed to be
excretion- decreased extraction, drugs might stay in system for longer then they should be and can cause problems
