Ephedrine can directly act on the α, β two receptors, play the role of adrenaline, but also to promote the release of adrenergic nerve endings of chemical neurotransmitters, play an indirect role of adrenaline. Compared with epinephrine, ephedrine is characterized by stable, orally active, the role of the weak and long-lasting, more significant role in excitability. With relaxation of bronchial smooth muscle, stimulate the heart, contraction of blood vessels, increase blood pressure and so on. Clinical use of bronchial asthma, spinal anesthesia or epidural anesthesia-induced hypotension and the lifting of nasal congestion and edema. The main side effects are anxiety, insomnia, tremor, palpitations, headache, dizziness, nausea, vomiting, loss of appetite, high blood pressure, urine retention, sweating and skin rash.
