What Is Blocadren?Blocadren® (timolol maleate) is a prescription medication approved for the following uses:
- Treating high blood pressure (known medically as hypertension)
- Reducing the risk of future heart attacks and heart-related death in people who have had a heart attack
- Preventing migraine headaches.
Who Makes This Medication?Brand-name Blocadren was made by Merck & Co., Inc., but is no longer being manufactured. A generic version, which is still available, is made by Mylan Pharmaceuticals.
How Does It Work?Blocadren belongs to a group of drugs called beta-adrenergic blocking agents, more often known as beta blockers. As the name implies, these medications block beta receptors in the body. Beta receptors are located in a number of places, including the heart and blood vessels. Stress hormones such as adrenaline bind to these receptors and cause certain reactions in the body, such as:
- Increased heart rate
- Increased force with which the heart pumps blood
- Higher blood pressure (both systolic blood pressure and diastolic blood pressure)
- Constricted blood vessels.
