Which class of drugs is indicated by the suffix "-pine"?

• A. Diuretics
• B. Beta blockers
• C. Calcium channel blockers (CCBs)
• D. Beta agonists

Answer: (C)

The suffix "-pine" is commonly associated with a specific class of medications known as calcium channel blockers (CCBs). These drugs work by inhibiting the influx of calcium ions through voltage-gated calcium channels in the heart and vascular smooth muscle. This action leads to vasodilation, decreased myocardial contractility, and ultimately results in lower blood pressure and reduced cardiac workload.

Calcium channel blockers are often prescribed for conditions such as hypertension, angina, and certain types of arrhythmias. The "-pine" suffix is particularly found in the names of several common CCBs, including amlodipine, nifedipine, and felodipine. Recognizing this characteristic can help healthcare professionals identify these medications and their therapeutic uses effectively.

Understanding the pharmacological mechanisms and the naming conventions of drug classes is essential in pharmacology, especially in clinical settings where accurate medication management is crucial.
