Levamlodipine besylate tablets (Shihuida) can be taken apart. Shihuida is the best-selling antihypertensive drug at the molecular level, not a sustained-release or controlled-release agent. It can be disassembled without affecting the absorption of drugs. For hypertensive patients who can't take drugs orally normally, such as consciousness disorder or coma, they can be ground into powder or given by nasal feeding, and the curative effect will not be affected. However, in order to ensure the antihypertensive effect, the patient's blood pressure is lower than 120/70mmHg after the antihypertensive treatment reaches the standard. Although it is possible, it is not recommended to bring Shihuida.

Occasionally, the antihypertensive effect will not be affected if Shihuida is missed once, but taking it every other day will lead to large fluctuations in blood concentration, or even forgetting to take the medicine because the interval is too long, which can not achieve a stable antihypertensive effect, so it can not be taken every other day.
