Pharmacology
Galcanezumab-gnlm is a humanized monoclonal antibody that binds to calcitonin gene-related peptide (CGRP) ligand and blocks its binding to the receptor; it is not metabolized by cytochrome P450 enzymes, making interactions with CYP substrates, inducers, or inhibitors unlikely.
Topiramate blocks voltage-dependent sodium channels, augments GABA-A receptor activity, antagonizes the AMPA/kainate subtype of the glutamate receptor, and inhibits carbonic anhydrase isozymes II and IV; the precise mechanisms underlying its anticonvulsant and preventive migraine effects are unknown.
