The applications of Synephrine in the field of medicine mainly include the following aspects:
Bronchial asthma: Synephrine has strong dilatation of trachea and bronchus and can counteract histamine-induced bronchoconstriction, so it is commonly used in the treatment of bronchial asthma.
Hypotension and related conditions: Synephrine acts as an adrenergic alpha receptor stimulant, which can constrict blood vessels and increase peripheral resistance, thus elevating blood pressure. It is used in the treatment of hypotension during surgery and anesthesia, collapse, shock, and postural hypotension.
Adjuvant therapy for cardiovascular diseases: Synephrine enhances myocardial contractility, increases cardiac output, and increases total peripheral vascular resistance, thereby elevating left ventricular pressure and arterial blood pressure. It has been used to resuscitate various types of shock and heart failure.
Digestive system diseases: Synephrine can inhibit the contraction of gastrointestinal smooth muscle, increase the secretion of gastric juice, and promote digestion, which is used to treat digestive system diseases such as oesophagus and gastroptosis.
Benign memory disorders and cognitive disorders: Synephrine improves attention, memory and cognitive function by acting on the central nervous system, and can be used to assist in the treatment of benign memory disorders and significantly improve cognitive function in patients with dementia.
