High blood pressure caused by the after-effects of methamphetamine is effective in taking antihypertensive drugs. The main component of methamphetamine is methamphetamine, which excites the central nervous system, activates the peripheral sympathetic nerves, and releases 5 hydroxytryptamine, which excites the body and increases the heart rate, leading to an increase in blood pressure. This blood pressure is a transient and transient increase, and the blood pressure will return to normal after the drug is metabolized. Abnormally high blood pressure after methamphetamine use has the risk of causing cerebral infarction and cerebral hemorrhage, so you can take antihypertensive drugs to lower your blood pressure. After the drug is metabolized, the blood pressure still cannot return to normal, considering that there is still primary hypertension, and long-term oral antihypertensive drugs are needed to control the blood pressure level. Methamphetamine is harmful to health, to the blood pressure, heart rate, nervous system are damaged, it is recommended to be detoxification.
