Mechanisms compared
Lexapro: Lexapro acts by selectively inhibiting the serotonin reuptake transporter (SERT) at the synapse, increasing serotonin availability for postsynaptic receptors. Metformin: Metformin's principal effect is to suppress hepatic glucose production by inhibiting mitochondrial complex I, which raises the cellular AMP/ATP ratio and activates AMP-activated protein kinase.
When the comparison makes sense
Comparing Lexapro with Metformin makes sense when both are in the same clinical decision: the prescriber has weighed both for different but related conditions. If the question is between two options for the same need, the prescriber decides based on prior response, comorbidities and tolerance.
