Coenzyme Q10 is an endogenous lipid soluble antioxidant that plays a crucial role in energy metabolism and cell protection as a key component of the mitochondrial electron transport chain. Japan classifies it as a metabolic stimulant, mainly used to improve abnormal myocardial energy metabolism and related diseases.

1. Mechanism of action

(1) Energy metabolism regulation: As an electron carrier in the mitochondrial respiratory chain, it promotes ATP synthesis and enhances energy supply to myocardial cells.

(2) Antioxidant effect: Clears free radicals, inhibits lipid peroxidation, and protects cell membrane integrity.

(3) Membrane stabilization function: maintains the stability of calcium ion channels, improves myocardial contractility and diastolic function.

2. Pharmacokinetic characteristics

(1) Absorption: Oral bioavailability is 2-3%, and micronized formulations can increase it to 5-10%.

(2) Distribution: Mainly enriched in mitochondrial membrane (10-20 times higher in heart concentration than in plasma).

(3) Metabolism: Reduced to the form of panthenol by the liver CYP450 system and reused.

3. Indications for Japanese metabolic stimulants

(1) Cardiovascular diseases, including chronic heart failure, angina pectoris, myocarditis, etc., can improve heart function grading and exercise tolerance.

(2) Neurodegenerative diseases: Adjuvant treatment for Parkinson's disease and Alzheimer's disease to delay the progression of neuronal damage.

(3) Metabolic diseases: auxiliary treatment of mitochondrial myopathy and diabetes complications to improve energy metabolism abnormalities.

4. Special applications of metabolic stimulants in Japan

(1) Chemotherapy protection: reduces the cardiac toxicity of drugs such as doxorubicin and lowers the risk of myocardial injury.

(2) Aging related symptoms: improve age-related energy metabolism disorders such as fatigue and cognitive decline.
