TRANDATE- Consumer Medicine Information Page 1 of 4 TRANDATE TM _LABETALOL HYDROCHLORIDE_ CONSUMER MEDICINE INFORMATION (CMI) WHAT IS IN THIS LEAFLET This leaflet answers some common questions about TRANDATE tablets. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist. All medicines have risks and benefits. Your doctor has weighed the risks of you taking TRANDATE against the benefits he or she expects it will have. IF YOU HAVE ANY CONCERNS ABOUT TAKING THIS MEDICINE, ASK YOUR DOCTOR OR PHARMACIST. KEEP THIS LEAFLET WITH THE MEDICINE. You may need to read it again. WHAT TRANDATE IS USED FOR The name of your medicine is TRANDATE. The active ingredient is called _labetalol hydrochloride_. _Labetalol hydrochloride_ belongs to a group of medicines called the beta- blockers. The beta- blockers are used for the treatment of high blood pressure (hypertension). TRANDATE is used for the treatment of all degrees of hypertension. Hypertension is a condition marked by high blood pressure. TRANDATE is used to lower high blood pressure. It works by changing the body’s response to some nerve impulses. Therefore, it widens the blood vessels in the body, causing the blood pressure to fall. Your doctor may have prescribed this medicine for another condition. ASK YOUR DOCTOR IF YOU HAVE ANY QUESTIONS ABOUT WHY TRANDATE HAS BEEN PRESCRIBED FOR YOU. TRANDATE tablets are only available with a doctor’s prescription.

TRANDATE- Product Information Page 1 of 10 PRODUCT INFORMATION APPROVED NAME: Labetalol hydrochloride TRADE NAME: Trandate™ CHEMICAL FORMULA COMPOSITION: Labetalol hydrochloride is a dry powder. The chemical name is: 2-hydroxy-5[1-hydroxy-2(1- methyl-3-phenylpropyl amino) ethyl] benzamide hydrochloride. PHARMACOLOGY: Trandate antagonises alpha- and beta-adrenoceptors concurrently by competitive inhibition; it has no intrinsic sympathomimetic activity and less pronounced membrane stabilising activity than propranolol. The beta-blockade is non-selective. Trandate has two centres of chirality which means that four isomers are possible, each of the isomers having different relative alpha- and beta-blocking activities. MODE OF ACTION Trandate lowers blood pressure by blocking alpha-adrenoceptors in peripheral arterioles and thereby reducing peripheral resistance. Trandate also concurrently blocks beta-adrenoceptors, notably in the heart, from the reflexly mediated drive caused by the peripheral vasodilatation. Therefore, the reduction in blood pressure is achieved without cardiac stimulation. Trandate does not reduce cardiac output at rest, or after moderate exercise. Normally occurring increases in systolic pressure during exercise are, however, lessened by Trandate; corresponding changes in the diastolic pressure are not affected. The precise relationship between alpha- and beta-blocking effects in contributing to the antihypertensive action is unknown. At therapeutic doses, Trandate is less active at alpha- adrenoceptors than beta-adrenoceptors, and adequate vasodilatation is achieved with incomplete blockade of the a Read the complete document
