Mechanisms compared
Valtrex: Valacyclovir is rapidly and almost completely converted to acyclovir during first-pass intestinal and hepatic metabolism by valacyclovir hydrolase. Clopidogrel: Clopidogrel itself is inactive; the active metabolite, formed in the liver by CYP2C19 and other cytochromes, irreversibly binds the P2Y12 ADP receptor on platelets.
When the comparison makes sense
Comparing Valtrex with Clopidogrel 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.
