A man suddenly fainted after breaking open his blood pressure medication. Recently, a man in Fujian reduced his medication dosage by breaking open his antihypertensive pills and taking them himself. As a result, his blood pressure dropped sharply to the point where it could not be measured within just 30 minutes, and he collapsed into a coma. He was rushed to the hospital for emergency treatment and was out of danger. Lin Jianzhen, associate chief physician of the cardiology department at the provincial-level hospital in Fujian, explained that the patient was taking a type of antihypertensive medication called controlled-release tablets. These tablets are specially designed to release medication evenly over 24 hours. Breaking or chewing the tablets destroys the controlled-release structure, causing the entire dose to be released rapidly in a short period, which can lead to a sudden and severe drop in blood pressure. Doctors warn that medications containing words like "sustained release," "controlled release," or "enteric-coated" in their names must never be broken or chewed before taking. It is also strictly forbidden to break adult medication to give to children, as this can seriously endanger life.
