Metabolic agents (local classification). Russian and Latvian development.
ATC code: C01EB-MELDONIUM (Meldonium (Mildronate) – local code)
Brand names
Mildronate, Quaterine
Meldonium (3-(2,2,2-trimethylhydrazinium) propionate, trade name Mildronate) is a structural analogue of gamma-butyrobetaine and an inhibitor of gamma-butyrobetaine hydroxylase. It reduces endogenous carnitine biosynthesis and shifts myocardial energy metabolism from long-chain fatty acid oxidation toward glucose oxidation, which is theoretically more oxygen-efficient under ischaemia. The molecule was developed at the Latvian Institute of Organic Synthesis in the 1970s. Meldonium is registered as a prescription drug only in Russia, Latvia and several other former Soviet states. It is not approved by the , or MHRA. The World Anti-Doping Agency added meldonium to the Prohibited List effective 1 January 2016 after surveillance data documented widespread use among elite athletes for ergogenic purposes.
The drug is promoted for these uses outside international guidelines. Each entry below is analyzed against AEMPS, FDA, EMA, Cochrane and major RCTs.
Not recommended
Evidence tier F (and prohibited). WADA added meldonium to the Prohibited List on 1 January 2016 after pre-listing surveillance found the drug in samples from more than 180 athletes at the 2015 European Games and in numerous post-Soviet competitors across endurance sports. A high-profile sanction followed: tennis player Maria Sharapova received a provisional ban in March 2016. The drug is not approved as an ergogenic aid by any regulator. Independent RCTs in healthy athletes are absent. Use of meldonium by competitive athletes triggers anti-doping sanctions regardless of intent.
Not recommended
Evidence tier F. The diagnostic category "chronic cerebrovascular insufficiency" used to justify meldonium prescribing in Russian outpatient care is absent from ICD-11 and from international neurology. Meldonium is not listed in any international vascular cognitive impairment or stroke prevention guideline. In patients with prior stroke or TIA, evidence-based secondary prevention is antiplatelet therapy (or anticoagulation for atrial fibrillation), high-intensity statin, blood pressure control to under 130/80 mmHg in most adults and diabetes management.
Not recommended
Evidence tier D. International cardiology guidelines ( 2024 chronic coronary syndromes, 2023 chronic CAD) do not list meldonium. Available trials are predominantly Russian-language, single-centre, with surrogate endpoints (exercise tolerance, anginal frequency by diary) rather than hard outcomes (cardiovascular mortality, myocardial infarction). Independent meta-analysis with low risk of bias has not been published. Evidence-based stable angina therapy is beta-blockers or calcium channel blockers for symptom control, antiplatelet therapy and high-intensity statin for prognosis, plus revascularisation in selected anatomy.
