NCT04617600 ↗ Survival Rate After TheraCal PT Pulpotomy Versus MTA Pulpotomy in Children With Vital Primary Molars. Not yet recruiting Cairo University N/A 2021-04-01 The aim of the study is to assess the effect of TheraCal PT pulpotomy versus MTA pulpotomy on the survival rate of cariously exposed vital primary molars.
NCT02603198 ↗ 2%-Mepivacaine With Two Different Vasoconstrictors Solutions in Third Molar Surgery a Comparative Study Unknown status University of Sao Paulo N/A 2014-08-01 Dental treatments, particularly third molars extraction, can become extremely uncomfortable and painful. They are associated to anxiety, fear and many other unpleasant sensations. During surgery, patients can present cardiorespiratory repercussions of these sensations. This fact generally justifies the employment of methods of monitoring and appliance of safer therapeutic alternatives. Local anesthetics are the most frequently drugs used in dentistry. Vasoconstrictors, particularly epinephrine, are important components of anesthetic solutions to increased time for anesthetic absorption and consequently increasing the duration of anesthesia. The use of smaller amounts of anesthetic solution can reduce the risk of systemic toxicity, however decrease the total surgical time. It is well known that the amount of epinephrine injected into patients during anesthetic procedures can produce adverse hemodynamic effects. Levonordefrin was adding to dental cartridges promising to reduce cardiac stimulation due it less β activity, and maintain the same clinical and systemic effects. But some studies for maxillary or intraosseous infiltrations showed no difference in heart rate and any anesthetic success over epinephrine. Thus, this study aims to compare the clinical efficacy and safety of anesthetic mepivacaine 2% with epinephrine 1:100,000 or 1:20,000 levonordefrin employing a clinical trial model of third molars extractions in healthy adults.

Levonordefrin and Mepivacaine Hydrochloride: Clinical Trials, Market Analysis, and Projections

Overview of Levonordefrin and Mepivacaine Hydrochloride

Levonordefrin, also known as Corbadrine or BA 2818, is a sympathomimetic amine used as a vasoconstrictor in local anesthetic solutions. It is often combined with local anesthetics like mepivacaine hydrochloride to enhance the efficacy and duration of anesthesia during dental procedures.

Mechanism of Action

Levonordefrin acts by binding to alpha-adrenergic receptors, particularly the alpha-2 adrenergic receptors, causing vasoconstriction. This mechanism is similar to that of epinephrine but is more stable and less potent in raising blood pressure[5].

Clinical Trials Update

Ongoing and Recent Trials

Several clinical trials have been conducted or are ongoing to evaluate the efficacy and safety of levonordefrin when combined with mepivacaine hydrochloride.

  • Evaluation of Healing Process and Blood Sugar Level: A double-blind randomized clinical trial (NCT05875519) is evaluating the healing of extraction sockets and glycemic levels in diabetic patients after local anesthetic infiltration with and without vasoconstrictor. This trial started in May 2023 and is currently active but not recruiting participants[2].

  • Anesthetic Efficacy Comparison: A prospective, randomized, double-blind crossover study compared the anesthetic efficacy of 2% mepivacaine with 1:20,000 levonordefrin versus 2% lidocaine with 1:100,000 epinephrine in maxillary central incisors and first molars. The study found that both formulations were similar in terms of anesthetic success and duration of pulpal anesthesia[3].

Key Findings

  • Anesthetic Success: Studies have shown that 2% mepivacaine with 1:20,000 levonordefrin has a high success rate for pulpal anesthesia, comparable to 2% lidocaine with 1:100,000 epinephrine. The success rates were 87% for central incisors and 90% for first molars[3].

  • Duration of Anesthesia: The duration of pulpal anesthesia for both formulations was similar, with approximately 87% of subjects having pulpal anesthesia at 30 minutes, 67% at 45 minutes, and around 50% at 60 minutes[3].

  • Safety and Efficacy: The combination of mepivacaine with levonordefrin has been found to be safe and effective, with superior pain control during the injection phase compared to lidocaine with epinephrine in some studies[2][3].

Market Analysis

Current Market Status

Levonordefrin, particularly when combined with mepivacaine hydrochloride, is a significant player in the dental anesthesia market. The global market for dental anesthetics is driven by the increasing demand for dental procedures and the need for effective and safe anesthetic solutions.

Market Projections

While specific market projections for levonordefrin and mepivacaine hydrochloride are not readily available, the overall dental anesthesia market is expected to grow due to several factors:

  • Increasing Dental Procedures: The rise in dental procedures, including cosmetic and restorative dentistry, is expected to drive the demand for local anesthetics.
  • Advancements in Dental Care: Improvements in dental care and the introduction of new anesthetic formulations are likely to contribute to market growth.
  • Global Health Trends: The global focus on healthcare and the increasing awareness of oral health will also play a role in the market's expansion.

Competitive Landscape

The market for dental anesthetics is competitive, with several key players offering various formulations. Levonordefrin, due to its stability and efficacy, remains a viable option for dental practitioners. However, it competes with other vasoconstrictors like epinephrine and phenylephrine, which are also widely used in dental procedures[2][3].

Therapeutic Areas and Indications

Dental Anesthesia

Levonordefrin is primarily used as a vasoconstrictor in local anesthetic solutions for dental procedures. It helps in reducing bleeding at the surgical site and prolonging the duration of anesthesia.

Active Indications

  • Anesthesia: Levonordefrin is indicated for use in dental anesthesia to provide effective pain relief and reduce bleeding during procedures[2].

Potential Future Indications

While currently focused on dental anesthesia, research into the pharmacological properties of levonordefrin could potentially expand its therapeutic areas. However, any new indications would require extensive clinical trials and regulatory approvals.

Safety and Adverse Effects

Drug Interactions

Levonordefrin can interact with various medications, including beta-adrenergic blocking agents, which can lead to significant hypertension and reflex bradycardia. It is also known to increase the risk of hypertension when combined with certain NSAIDs and other medications[5].

Contraindications and Blackbox Warnings

Patients with significant cardiovascular disease are particularly vulnerable to the adverse effects of levonordefrin, such as pressor reactions. Inadvertent intravascular injections of local anesthetic plus vasoconstrictor can result in severe reactions[2][5].

Pharmacology and Pharmacodynamics

Mechanism of Action

Levonordefrin mimics the molecular shape of adrenaline and binds to alpha-adrenergic receptors, causing vasoconstriction. This action is crucial in reducing bleeding and prolonging the duration of local anesthesia[5].

Absorption, Distribution, and Elimination

Detailed information on the absorption, volume of distribution, protein binding, metabolism, and route of elimination of levonordefrin is not readily available. However, its pharmacodynamic effects are well-documented, highlighting its role as a vasoconstrictor[5].

Regulatory Status

R&D Status

Levonordefrin is currently in the clinical phase of development, with ongoing trials evaluating its efficacy and safety in various dental procedures. It was initially developed by The Ohio State University and is now being researched globally[1].

Approval Status

While levonordefrin is used in clinical settings, specific approval dates and regulatory statuses may vary by region. It is essential to check with local health authorities for the most current information.

Key Takeaways

  • Clinical Trials: Ongoing trials are evaluating the efficacy and safety of levonordefrin combined with mepivacaine hydrochloride, showing promising results in dental anesthesia.
  • Market Analysis: The dental anesthesia market is expected to grow, driven by increasing dental procedures and advancements in dental care.
  • Therapeutic Areas: Levonordefrin is primarily used in dental anesthesia but may have potential future indications.
  • Safety and Adverse Effects: It is crucial to be aware of drug interactions and contraindications, especially in patients with cardiovascular disease.
  • Pharmacology: Levonordefrin acts as a vasoconstrictor by binding to alpha-adrenergic receptors, mimicking the action of adrenaline.
