Final answer:
Beta-blocking medications such as metoprolol and propranolol are prescribed to treat cardiovascular diseases by blocking β-receptors and improving cardiac function. Care must be taken in their use to avoid adverse effects.
Step-by-step explanation:
Beta-blocking medications, also known as β-blockers, are a class of drugs commonly prescribed to treat cardiovascular conditions by inhibiting the action of certain neurotransmitters on the heart. These medications work by blocking the β-receptors, which can lead to vasoconstriction and increased heart rate. Some examples of β-blockers include metoprolol, which is selective for the β1-receptor, and propranolol, a non-selective β-blocker that blocks multiple β-receptors. These drugs can be essential in improving cardiac function in patients with conditions like congestive heart failure or post-heart attack management.
It is important to note that while β-blockers are beneficial in treating hypertension and other heart-related issues, oversight in prescribing these medications can lead to adverse effects such as bradycardia or even cardiac arrest.
