Mechanism of action: Due to structural noradrenaline through its presynaptic membrane transport mechanisms ephedrine enters the neuron, displaces norepinephrine from landfills and releases it into the presynaptic cleft without the involvement of calcium ions. The released neurotransmitter binding is a postsynaptic adrenergic receptors and causes increased sympathomimetic activity. Although less postsianptichnite interact with alpha 1, alpha 2 beta 1 and beta 2 - receptor (more pronounced with beta 2 - receptors). Inhibit MAO activity. This complex mechanism of action as it determines simpatikomimetik mixed (direct and indirect) mechanism of action and determines its various clinical effects. Causes peripheral vasospasm, increased heart rate, increases blood pressure, causes bronchodilation, inhibits intestinal motility and causes dilation of the pupil. Increases in blood sugar occurs stimulatory effect on the central nervous system (mental and motor disorders, insomnia) and increases the excitability of the respiratory center.
