    RCT NEJM (459 femmes hyperprolactinémiques) : cabergoline 0,5-1 mg ×2/sem supérieure à bromocriptine — normalisation de la prolactine chez 83 % vs 59 %, meilleure tolérance (moins de nausées). Demi-vie longue de la cabergoline (~65 h) permet une administration 2× / sem.

    Étude de cohorte multicentrique (455 patients hyperprolactinémiques traités jusqu'à 8 ans par cabergoline 0,25-3 mg/sem) : normalisation prolactine chez 86 %, réduction du volume tumoral des prolactinomes, profil de tolérance favorable à long terme.

    Étude NEJM chez patients parkinsoniens sous cabergoline à fortes doses (>3 mg/j chronique) : augmentation significative de la fréquence de régurgitations valvulaires (cardiopathie valvulaire) — effet dose-dépendant via agonisme 5-HT2B sérotoninergique.

    Étude chez 50 patients sous cabergoline pour prolactinome (dose médiane 1 mg/sem, durée moyenne 8 ans) : prévalence accrue de régurgitation tricuspide modérée à sévère vs contrôles — signal de sécurité même à doses « endocrinologiques » plus modestes.

    Énoncé Endocrine Society : la cabergoline est utilisée hors AMM par les bodybuilders pour gérer l'hyperprolactinémie induite par les cures progestatives (nandrolone, trenbolone) — mécanisme valide, doses bas-modérées généralement sûres, mais usage prolongé non encadré déconseillé.
