Summary
Barbiturates can lower exposure to many beta-blockers by inducing hepatic metabolism. Nadolol is mostly renally excreted and unmetabolized, so any effect is likely small.
What this interaction means in plain words
Amobarbital and Nadolol have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Amobarbital belongs to Central Nervous System; Nadolol belongs to Cardiovascular.
Why it happens
Barbiturate hepatic enzyme induction, which has limited relevance for renally cleared nadolol.
What to do
Monitor heart rate and blood pressure when starting or stopping amobarbital. Adjust nadolol only if response changes.
