Metaraminol tartrate is an α-adrenergic agonist and a sympathomimetic amine. It directly and indirectly affects adrenergic receptors, with a predominant alpha effect, and acts as a vasopressor agent.
- Stimulation of α-adrenoceptors by metaraminol has been shown to accelerate cell proliferation in colonie crypts.
- Lethal endotoxin shock was prevented in a study involving dogs.
- It has been investigated in clinical trials for conditions such as preeclampsia, cesarean section complications, and hypotension.
