Answer:
Drug Y is a more potent drug than drug X, while drug X is more efficacious than drug Y.
Explanation:
The efficacy of a drug has to do with the therapeutic effectiveness of the drug. It is the maximum effect a drug has irrespective of the dosage or concentration.
Drug X has a higher effect as it lowers cholesterol by 65mg/dL (maximum effect), than drug Y which lowers by 55mg/dL, thus making drug X more efficacious than drug Y.
Potency on the other hand, has to do with drug concentration and is the amount of drug needed to produce a required effect. Drug X is required in 10mg before it has a lowering effect of 50mg/dL while drug Y is required in 5mg to produce the same effect. This makes drug Y more potent than X because a lower dose is required.
