The mechanism of action of methyldopa has yet to be conclusively demonstrated, but probably it is due to the metabolism of this drug to alpha-methylnorepinephrine, which lowers arterial pressure by stimulation of central inhibitory alpha-adrenergic receptors. It gives false neurotransmission, and reduces plasma renin activity.
Metil dopa 250 mg tablets are indicated in the treatment of hypertension.
Solution for injection - ( 0.1%) 1 mg/1 ml
Adrenaline is an endogenous substance that is produced in the adrenal medulla and has important physiological effects. It is a potent agonist at both alpha and beta adrenoceptors, although the effect on beta adrenoceptors is more marked, particularly at lower doses.
The major effects of adrenaline are dose-related and include:
dilatation of the bronchi, narrowing of blood vessels, increased heart rate and contractility (positive chronotropic and inotropic effect) and stimulation at central level. Adrenaline is a histamine antagonist. It is used for the treatment of life emergencies.
Adrenaline is used in acute allergic reactions and anaphylactic shock.
It is also used in advanced cardiac life support.
