Explanation / Answer
Answer: A) Drugs are being developed that affect only one subclass of receptor without upsetting the entire system
Explanation: Specific drugs are being developed to obtain the desired blocking of stimulatory effects on selected target organs. For example; the adrenergic blockers that attach specifically to the beta receptors of cardiac muscle (beta-blockers) like atenolol are used when the goal is to reduce heart rate and prevent arrhythmias in patients without interfering with other sympathetic effects in the human body.
