Glucophage belongs to Diabetes Treatment while Avodart belongs to Male and Female Pattern Hair Loss. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Glucophage: Metformin reduces hepatic glucose production through inhibition of mitochondrial complex I, which raises the cellular AMP/ATP ratio and activates AMP-activated protein kinase. Avodart: Avodart inhibits both isoforms of 5α-reductase, the enzyme that converts testosterone to dihydrotestosterone (DHT).
When Glucophage is preferred
The medication is indicated as first-line oral therapy in adults with type 2 diabetes mellitus, alone or in combination with other antidiabetic agents, including insulin.
When Avodart is preferred
Avodart is approved for the treatment of moderate to severe symptomatic benign prostatic hyperplasia, alone or in combination with the alpha-blocker tamsulosin.
