Coenzyme Q10 is a naturally occurring benzoquinone important in electron transport in mitochondrial membranes. Coenzyme Q10 functions as an endogenous antioxidant; deficiencies of this enzyme have been observed in patients with many different types of cancer and limited studies have suggested that coenzyme Q10 may induce tumor regression in patients with breast cancer. This agent may have immunostimulatory effects. (NCI04)

4 Drug and Medication Information
4.1 Drug Indication

The diet supplements containing ubidecarenone are indicated, as stated in the product label, to assist individuals with cardiovascular complaints including congestive heart failure and systolic hypertension. In the product, ubidecarenone is used to increase the cardiac input as well as for the prevention of several other diseases like Parkinson, fibromyalgia, migraine, periodontal disease and diabetes, based on preclinical studies. It is important to highlight that these products are not FDA approved and it is recommended to use under discretion.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Ubidecarenon has roles in many prysiological process including sulfide oxidation, regulation of mitochondrial permeability transition pore and translocation of protons and calcium ions accross biological membranes. Studies have shown its benefitial effect in treating cancer, statin myopathy, congestive heart failure and hypertension.


5.2 MeSH Pharmacological Classification

Vitamins

Organic substances that are required in small amounts for maintenance and growth, but which cannot be manufactured by the human body. (See all compounds classified as Vitamins.)


5.3 ATC Code

C - Cardiovascular system

C01 - Cardiac therapy

C01E - Other cardiac preparations

C01EB - Other cardiac preparations

C01EB09 - Ubidecarenone


5.4 Absorption, Distribution and Excretion

Absorption

Ubidecarenone is absorbed from the small intestine into the lymphatics and then it can enter the blood. The hydrophobicity and large molecular weight limit its absorption making it very poor and variable depending on the food intake and the number of lipids presented in the food. The absorption is lower in the presence of an empty stomach and greater in presence of high lipid food diet. The daily dosage of ubidecarenone presents the reach of maximal serum concentration by reaching a plateau after three weeks. The pharmacokinetic properties may vary between different brands but studies have reported an AUC of 11.51 mcg h/ml and a Cmax of 0.32 mcg/ml at a time of 7.9 h.


Route of Elimination

The main elimination route of ubidecarenone is through the bile. After its oral administration, over 60% of the dose is excreted in the feces in the form of unchanged ubidecarenone and a small fraction of the metabolites. In the urine, ubidecarenone is bound to saposin B protein and represents only 8.3% of the total administered dose.


Volume of Distribution

Ubidecarenone is distributed to the various tissues of the body and it is able to enter the brain. In preclinical studies with intravenous administration of ubidecarenone, it is reported a volume of distribution of 20.4 L/kg which reflects its ability to penetrate extensively into organs and tissues. AS a general rule, tissues with high-energy requirements or metabolic activity tend to presents higher amounts of ubidecarenone, these organs can be heart, kidney, liver and muscle.


Clearance

In preclinical studies with intravenous administration of ubidecarenone, it is reported a total clearance of 1.18 ml h/kg which was indicative of a prolonged elimination.


5.5 Metabolism/Metabolites

Studies indicate that there is no saturation process during the metabolism of ubidecarenone. It is metabolized in all tissues by the phosphorylation in the cells and transportation to the kidneys for further excretion by the urine. After exerting its action, ubidecarenone is reduced and forms hydroquinone which is capable of recycling and regenerates other antioxidants such as tocopherol and ascorbate. The later metabolism of hydroquinone generates the formation of Q acid I and Q acid II in free and conjugated forms.


5.6 Biological Half-Life

The pharmacokinetic properties may vary between different brands but studies have reported a half-life of ubidecarenone of 21.7 h.


5.7 Mechanism of Action

Ubidecarenone is an essential cofactor in the mitochondrial electron transport chain. Its functions are the acceptance of electrons from the complex I and II and this activity is vital for the production of ATP. It acts as a mobile redox agent shuttling electrons and protons in the electron transport chain. Ubidecarenone also presents antioxidant activity in mitochondria and cellular membranes, protecting against peroxidation of lipid membranes as well as inhibiting oxidation of LDL-cholesterol.
