How Does It Work?

Kerlone is a beta-adrenergic blocking agent, more often known as a beta blocker. As you might guess, these medications work by blocking beta receptors in the body. Beta receptors are located in a number of places within the body, including the heart and blood vessels. Stress hormones (such as adrenaline) bind to these receptors and cause certain reactions in the body, such as:
By blocking beta receptors, Kerlone causes the reverse effect of stress hormones and reduces blood pressure. It is important to note that Kerlone is more likely to block beta-1 receptors (such as those in the heart and blood vessels), opposed to beta-2 receptors (such as those found in the lungs), which can theoretically make the medication safer than other beta blockers for people with breathing problems such as asthma.
