What It Treats
lefamulin

Xenleta treats community-acquired bacterial pneumonia (CABP) in adults. This type of pneumonia is caused by germs like Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Legionella pneumophila, Mycoplasma pneumoniae, and Chlamydophila pneumoniae. This medicine should only be used to treat infections that are proven or very likely to be caused by bacteria.

verapamil

Verapamil is used to treat chest pain called angina. This includes angina that happens when you are resting or during normal activity. It is also used to control your heart rate if you have a fast or irregular heartbeat, such as atrial fibrillation or atrial flutter. Verapamil also treats high blood pressure.

How It Works
lefamulin

Xenleta is a pleuromutilin antibiotic. It works by stopping bacteria from growing. This helps your body fight off the infection.

verapamil

Verapamil belongs to a class of drugs called calcium channel blockers. It works by blocking calcium from entering heart and blood vessel cells. This relaxes and widens blood vessels, which lowers blood pressure and makes it easier for the heart to pump.

Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, lefamulin has 0 submissions while verapamil has 1,579.
