Which of the following is a class of drugs that includes "olol"?

The class of drugs that includes "olol" is known as beta blockers. This designation stems from the common naming convention in pharmacology, where many beta blockers have names ending in "olol," such as atenolol, propranolol, and metoprolol. Beta blockers are primarily used to manage cardiovascular conditions such as hypertension, heart rhythm disorders, and heart failure by blocking the effects of adrenaline on the beta-adrenergic receptors in the heart, leading to a decrease in heart rate and blood pressure.

Understanding this naming convention is important for pharmacy technicians, as it helps in identifying medication classes quickly and effectively, ensuring safe and accurate dispensing of prescriptions. This familiarity with drug classes and their respective suffixes is crucial for recognizing potential side effects and interactions, as well as providing appropriate counseling to patients regarding their medications.
