Summary
amlodipine/benazepril

Lotrel is a combination medicine that contains amlodipine and benazepril. It is used to treat high blood pressure.

lithium

Lithium is a mood stabilizer medicine. It helps to balance mood swings.

What It Treats
amlodipine/benazepril

Lotrel is used to treat high blood pressure. It is for people whose blood pressure is not controlled well enough with just one medicine (either amlodipine or benazepril alone). This medicine helps to lower blood pressure, which can reduce the risk of strokes and heart attacks.

lithium

Lithium is used to treat bipolar disorder. Bipolar disorder causes unusual shifts in mood, energy, activity levels, and concentration. Lithium helps to control the extreme highs (mania) and lows (depression) of this condition.

How It Works
amlodipine/benazepril

Lotrel contains two medicines that work in different ways to lower blood pressure. Amlodipine relaxes and widens blood vessels so blood can flow more easily. Benazepril lowers blood pressure by preventing your body from making a substance that narrows blood vessels.

lithium

Lithium affects the flow of sodium in nerve and muscle cells in the body. This helps to stabilize your mood. It may also affect other chemical messenger systems in the brain.

How to Read This amlodipine/benazepril vs lithium Comparison

amlodipine/benazepril is classified in the Calcium Channel Blocker / ACE Inhibitor Combination drug class, while lithium sits within the Mood Stabilizer class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.

Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, amlodipine/benazepril has 67,052 submissions while lithium has 7,665. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known major interaction flagged in FDA labeling, attributed to benazepril can make it harder for the kidneys to remove lithium from the body, causing lithium levels to rise. this increase can lead to lithium poisoning or other serious side effects.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.

A table cannot substitute for clinical judgment. Effectiveness, tolerability, drug-drug interactions with your other medications, kidney and liver function, pregnancy status, insurance formulary, and price all feed into a decision that only a licensed prescriber can make responsibly. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information.
