Questions regarding change in medication

My husband recently switched from Fosinopril 20/12.5 to Toprol- xl. Could you explain the difference in the two medications which are used to treat high blood pressue. I have noticed my husband has been having more frequent hand tremors. He does have a history of alcoholism and was in in patient treatment 10 months ago and has been sober since.

Fosinopril is an angiotensin converting enzyme (ACE) inhibitor which lower blood pressure by reducing angiotensin levels.  It is a weak a blood pressure reduction medication.  Toprol is a beta receptor blocker which reduced blood pressure by blocking beta receptors.  Norepinephrine normally binds to Beta receptors and raises blood pressure, so beta blockers counteract that effect.  Typically beta blockers are a treatment for hand tremors so the fact that he's having more tremors while on the beta blockers is a bit surprising.
