Bystolic is a beta-blocker, which means that it blocks the effects of epinephrine, a hormone. This causes the heart to beat with less force and at a slower rate, reducing the pressure of the blood. Cozaar is an angiotensin II receptor antagonist, a medication that prevents the narrowing of blood vessels. This improves the blood flow throughout the body and reduces blood pressure. Though these drugs have two different mechanisms, they are both used to treat hypertension, or high blood pressure. In particular, Cozaar is also sometimes used to reduce risk of stroke in people who have heart disease and to slow the long-term kidney damage in those who have type 2 diabetes.

Bystolic is available in tablet form in 2.5mg, 5mg, 10mg, or 20mg doses. Cozaar is available in 12.5mg, 25mg, 50mg, and 100mg tablets. Dosage depends on the individual case, but dosage of Bystolic is usually 5mg once a day at first, increasing over time to 40mg. Dosage for Cozaar is usually 25-100mg per day in 1 or 2 doses daily. Cost may vary depending on where the medicine is bought. Generic versions of these drugs will be cheaper than branded versions.
