Mechanisms compared
Allegra: Fexofenadine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine on vasodilation, capillary permeability, sensory nerve endings and smooth muscle. Sertraline: Sertraline selectively blocks the reuptake of serotonin (5-HT) by the presynaptic neuron, increasing the concentration of serotonin in the synaptic cleft.
