Final answer:
Cardiomyopathy is not a known adverse effect of amiodarone. The medication can cause pulmonary fibrosis, photosensitive rash, corneal microdeposits, and thyrotoxicosis, but cardiomyopathy is not associated with its use.
Step-by-step explanation:
The question 'Which one of the following is NOT an adverse effect of amiodarone?' relates to the known side effects of the drug amiodarone. Amiodarone is a medication used to treat certain types of irregular heartbeat. While it is effective, it has several potential adverse effects. These include pulmonary fibrosis, photosensitive rash, and corneal microdeposits. Thyrotoxicosis is also a well-documented adverse effect since amiodarone contains iodine and can affect the thyroid gland. However, cardiomyopathy is not typically associated with the use of amiodarone. Therefore, the correct answer is D. cardiomyopathy.
