Mechanisms compared
Doxycycline: Doxycycline binds reversibly to the 30S ribosomal subunit of bacteria, preventing the binding of aminoacyl-tRNA and inhibiting protein synthesis. 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.

Comparing Doxycycline 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.
