What is Meldonium hydrate used for?

Meldonium hydrate, also known as Mildronate or by its chemical name 3-(2,2,2-Trimethylhydraziniumyl)propionate dihydrate, is a pharmaceutical agent that has garnered attention in both medical and athletic circles. Initially developed in the 1970s by the Latvian Institute of Organic Synthesis, this compound has primarily been marketed in the Baltic countries and Russia. Meldonium hydrate is often prescribed under trade names such as Mildronate and THP.

This drug functions as an anti-ischemic agent and is primarily used to treat chronic heart conditions, including angina and heart failure. Additionally, it has shown promise in improving physical performance and endurance, making it popular among athletes – albeit controversially. Current research is exploring its potential in treating various conditions like diabetes and neurodegenerative diseases due to its metabolic-modulating properties. Despite its benefits, Meldonium hydrate was thrust into the spotlight when it was added to the World Anti-Doping Agency's (WADA) list of banned substances in 2016, following reports of its performance-enhancing use in sports.

Meldonium hydrate Mechanism of Action

Understanding the mechanism of action of Meldonium hydrate involves delving into its effect on cellular metabolism. The drug acts by inhibiting the enzyme gamma-butyrobetaine hydroxylase, which is involved in the biosynthesis of carnitine. Carnitine plays a crucial role in the transport of fatty acids into the mitochondria for beta-oxidation, a key step in energy production within cells.

By reducing carnitine levels, Meldonium hydrate effectively shifts cellular energy production from fatty acid oxidation to glycolysis, a process that is less oxygen-intensive. This shift is particularly beneficial in ischemic conditions where oxygen supply is limited. The drug also exhibits properties that protect cells from oxidative stress and apoptosis, making it not only cardioprotective but also potentially neuroprotective. Its ability to regulate energy metabolism is what lends Meldonium hydrate its versatility in treating various conditions beyond cardiovascular diseases.

How to Use Meldonium hydrate

Administering Meldonium hydrate can be done via oral capsules, intravenous injections, or intramuscular injections. The method of administration often depends on the severity of the condition being treated. For chronic conditions like heart failure, oral capsules are commonly prescribed, typically in doses ranging from 500 mg to 1000 mg per day.

For acute conditions, such as an angina attack, intravenous or intramuscular injections are preferred due to their rapid onset of action. In such cases, the drug can begin to exert its effects within minutes, offering quick relief from symptoms. It's worth noting that the dosage and administration schedule should always be determined by a healthcare professional, tailored to the specific needs and health status of the patient.

What is Meldonium hydrate Side Effects

Like any pharmaceutical agent, Meldonium hydrate comes with its share of potential side effects and contraindications. Common side effects include gastrointestinal disturbances such as indigestion, nausea, and diarrhea. Some patients have reported experiencing headaches, dizziness, and an overall sense of weakness. Although these side effects are generally mild, they can be more pronounced in individuals with pre-existing health conditions.

More severe but less common side effects include allergic reactions, characterized by itching, rash, and swelling, particularly of the face and throat. Cardiovascular side effects, although rare, can also occur and may manifest as an irregular heartbeat or alterations in blood pressure.

It's crucial to note that Meldonium hydrate is contraindicated in patients with severely impaired kidney or liver function. Pregnant and breastfeeding women should avoid the drug due to the lack of sufficient safety data in these populations. Furthermore, given its inclusion on WADA's list of banned substances, athletes should steer clear of Meldonium unless they have an approved therapeutic use exemption.

What Other Drugs Will Affect Meldonium hydrate

Drug interactions are an important consideration when prescribing Meldonium hydrate. Since the drug alters cellular metabolism and has cardiovascular effects, it can interact with various other medications. For instance, Meldonium hydrate may potentiate the effects of other anti-ischemic drugs like nitrates, beta-blockers, and calcium channel blockers. This could lead to an increased risk of side effects such as hypotension and bradycardia.

In addition, Meldonium hydrate may interact with anticoagulant and antiplatelet medications, potentially altering their efficacy and increasing the risk of bleeding complications. Care should also be taken when combining Meldonium with medications that are metabolized by the liver, as this could affect the drug's pharmacokinetics and lead to either increased toxicity or decreased effectiveness.

Patients on medications for chronic conditions, such as diabetes, hypertension, or epilepsy, should consult their healthcare providers before starting Meldonium hydrate to ensure there are no adverse interactions. Regular monitoring and adjustments in dosages may be necessary to mitigate any potential risks.

In summary, Meldonium hydrate is a versatile pharmaceutical agent with a range of therapeutic applications, particularly in cardiovascular diseases. Its mechanism of action, focusing on altering cellular energy metabolism, offers benefits in ischemic conditions and beyond. However, its use is not without risks, including potential side effects and drug interactions, necessitating careful medical supervision. As ongoing research continues to elucidate its full range of effects and potential new applications, Meldonium hydrate remains a topic of significant interest within the medical community.
