  • Antihistamine: Medicines that relieve or prevent symptoms of allergies by blocking histamine action in the body.

  • Antacid: Substances that neutralize stomach acidity and are used to relieve heartburn, indigestion, or an upset stomach.

  • Neurotransmitter: Chemicals in the nervous system that transmit signals across a synapse from one neuron to another target neuron, muscle cell, or gland cell.

  • Antidepressant: Medications used to treat depressive disorders by altering chemical actions in the brain, especially neurotransmitters like serotonin, norepinephrine, and dopamine.

Noradrenaline (also called norepinephrine) is:

  • A chemical produced naturally in the body.

  • Mainly functions as a neurotransmitter in the central and peripheral nervous systems.

  • Plays a key role in the fight-or-flight response by increasing heart rate, triggering the release of glucose from energy stores, and increasing blood flow to skeletal muscles.
