Study Notes
Migraine - A Complex Disease
- Migraine is one of the most disabling and expensive chronic disorders, its etiology is still not fully understood.
- The functionality of neuronal systems (glutammatergic, dopaminergic, serotoninergic, and GABA-ergic) plays a significant role in migraine.
- Genetic predisposition plays a role in these neuronal system functionalities.
- Individual responses to migraine treatment vary due to different expressions of phase I enzymes (such as different isoforms of CYP P450), ** Phase II enzymes** (such as UDP-glucuronosyltransferases), receptors (such as OPRM1 for opioids) and transporters (such as ABCB1).
Treatment & Polytherapy
- Treating migraine involves multiple drug categories for both acute attacks and chronic forms of migraine.
- Polytherapies are frequently used to manage comorbidities that can interfere with the efficacy of anti-migraine drugs.
- Drug-drug interactions (DDIs) arise in polytherapy and are influenced by the individual's genetic traits.
- Personalized medicine aims to optimize therapies based on an individual's functional biochemistry and comorbidities.
Biomarkers for Personalized Treatment
- Neuropeptides, including CGRP (Calcitonin Gene-Related Peptide) substance P, PACAP (Pituitary Adenylate Cyclase-Activating Polypeptide), and nitric oxide play a role in migraine pathogenesis.
- CGRP's involvement in vasodilation of meningeal blood vessels and the subsequent stimulation of the parasympathetic system (via reflex) is a target for therapy.
- Novel therapeutic strategies for migraine include biotechnological drugs targeting CGRP and its receptor.
CGRP Antagonists for Effective Treatment
- Gepants are non-peptide CGRP antagonists that reduce the activity of the trigeminal-vascular system effectively.
- Olcegepant (BIBN4096BS) is the first CGRP receptor antagonist used successfully, binding to the RAMP1 portion of the receptor.
- Biotechnological drugs directed against CGRP offer promise for treating migraine effectively and selectively.
