Outrageously Funny Word Dictionary :: Phenylephrine

👉 Phenylephrine is a non-selective beta-adrenergic agonist, meaning it does not specifically target beta-adrenergic receptors. It acts by increasing heart rate and blood pressure in response to elevated levels of adrenaline or noradrenaline. This effect can be seen as an anticholinergic effect. The mechanism of action is thought to involve the stimulation of alpha-1 adrenergic receptors, which are located in the smooth muscle cells of the gastrointestinal tract.
