Chelsea midfielder Mihailo Mudric’s Meldonium ban lifted after four-year suspension

In October 2024, Chelsea FC player Mihailo Mudric tested positive for Meldonium, a substance classified under the S4 metabolic modulators list, resulting in a four‑year suspension. The player consistently asserted his innocence, and the disciplinary decision was recently overturned, permitting his return to professional football. Meldonium is not marketed in South Korea and is primarily used in Eastern European countries as a treatment for cardiovascular conditions. It acts on the enzyme γ‑butyrobetaine hydroxylase, which is involved in the synthesis of carnitine, a compound important for fatty‑acid metabolism.
