Which side effect could potentially occur with the use of anti-anginals?

• A. Drowsiness
• B. Flushing
• C. Insomnia
• D. Constipation

Answer: (B)

The selection of flushing as a potential side effect of anti-anginals is valid due to the pharmacological action of these medications. Anti-anginals, which are often nitrates or other related compounds, work to dilate blood vessels and improve blood flow to the heart. This vasodilation can cause an increase in blood flow to the skin, resulting in flushing, which is characterized by redness or warmth of the skin. Flushing specifically relates to the ability of these medications to relax vascular smooth muscle, leading to peripheral dilation. As blood vessels expand, more blood is directed toward the skin surface, causing the flushed appearance. Understanding the mechanism of action behind anti-anginals is essential, as it elucidates why flushing is a common and anticipated side effect. While drowsiness, insomnia, and constipation can occur with various medications, they are not typically associated with the use of anti-anginal drugs in the same manner as flushing. Drowsiness and insomnia are more closely linked to medications affecting the central nervous system rather than those focused on cardiovascular function. Constipation is often associated with medications that have anticholinergic effects or with opioids, neither of which are common in anti-anginal therapy.
