How to use
Follow the directions for using this medicine provided by your doctor. Take this medicine with food or milk.
Drug Class and Mechanism
Trandate is a drug that is used for treating high blood pressure. It is related to carvedilol (Coreg). Nerves that are part of the adrenergic nervous system travel to most arteries where they release an adrenergic chemical norepinephrine. The norepinephrine attaches to receptors on the muscles of the arteries and causes the muscles to contract, narrowing the arteries, and increasing the blood pressure. Trandate blocks receptors of the adrenergic nervous system. When trandate attaches to and blocks the receptors, the arterial muscles relax, and the arteries expand, resulting in a fall in blood pressure.
Missed Dose
Take the missed dose as soon as you remember. Skip the missed dose if your next dose is less than 8 hours away. Do not take extra medicine to make up the missed dose.
Storage
Store Trandate at 77 degrees F (25 degrees C). Brief storage between 59 and 86 degrees F (15 and 30 degrees C) is permitted. Store away from heat, moisture, and light. Do not store in the bathroom. Keep Trandate out of the reach of children and away from pets.
