Anesthetic Cream Import | Safe Methods to Obtain High-Concentration Lidocaine Cream | TASAKI PHAMA

Current Status and Needs for Importing Anesthetic Creams

In recent years, with the increasing demand for aesthetic medicine, there has been a growing need for anesthetic creams to alleviate pain during procedures such as laser treatment, microneedling (Dermapen), and injection therapies. Specifically, there is a demand for products containing higher concentrations of lidocaine than those available domestically, leading to increased interest in importing them from overseas.

Achieving sufficient anesthetic effect in these procedures is essential not only for improving patient satisfaction but also for the smooth progression of the treatment. If the pain is severe, patients may become anxious, potentially affecting the practitioner’s technique. Therefore, the demand for more effective anesthetic creams is an inevitable necessity in clinical practice.

However, importing anesthetic creams involves various considerations, including legal regulations and quality control. This article provides a detailed explanation of the characteristics and effects of high-concentration lidocaine creams, precautions during import, and proper usage and risk management.

Characteristics and Effects of High-Concentration Lidocaine Cream (10.56%)

Lidocaine is an amide-type compound widely used as a local anesthetic. It works by blocking sodium channels in nerve cells, thereby inhibiting the transmission of pain signals. The concentration of lidocaine in anesthetic creams varies by product and affects the duration and intensity of its effect.

Generally, lidocaine creams available domestically have a concentration of around 5%, but higher concentration products exceeding 10% exist overseas. For example, a 10.56% lidocaine cream can provide a more potent anesthetic effect and is suitable for procedures involving severe pain. In microneedling (Dermapen) treatments, it can effectively alleviate pain caused by needle stimulation, offering a more comfortable treatment experience.

However, when using high-concentration lidocaine cream, the risk of side effects must also be considered. It is crucial to properly manage the application area and duration, and to closely monitor the patient’s condition. Particularly, cautious administration is required for patients with allergies to lidocaine or those with cardiovascular diseases.

Mechanism of Action of Lidocaine Cream

Lidocaine reversibly blocks sodium channels located in the cell membranes of nerve cells. By inhibiting the influx of sodium ions, depolarization of nerve cells is suppressed, making it difficult for action potentials to be generated. As a result, pain signals are not transmitted to the brain, and an anesthetic effect is achieved.

Advantages and Disadvantages of High-Concentration Lidocaine Cream

• Advantages
  • Potent anesthetic effect
  • Suitable for procedures involving severe pain
  • Reduced patient stress during treatment
• Disadvantages
  • Higher risk of side effects
  • Careful management of application area and duration is crucial
  • Attention to allergic reactions is necessary

Precautions for Importing Anesthetic Creams from Overseas

When importing anesthetic creams from overseas, it is necessary to comply with legal regulations such as the Pharmaceuticals and Medical Devices Act (PMD Act) and the Customs Act. Even for personal use, there are restrictions on the quantity that can be imported, and permission from the Ministry of Health, Labour and Welfare may be required in some cases. Furthermore, the quality and safety of the imported products must be confirmed.

Specifically, the following points require attention:

• PMD Act Regulations: Anesthetic creams are classified as pharmaceuticals, so there are restrictions on the quantity that can be personally imported. Typically, the limit is set to a one-month supply per single import.
• Customs Duties: Customs duties may apply to imported anesthetic creams. The duty rate varies depending on the product type and quantity.
• Quality and Safety: Some overseas products may not have guaranteed quality or safety. It is crucial to purchase from reliable suppliers and verify product ingredient lists and manufacturer information.
• Import Agents: If personal import is difficult, using an import agent is an option. However, it is necessary to choose a trustworthy agent and thoroughly compare fees and services.

Choosing products approved by public authorities such as the U.S. Food and Drug Administration (FDA) or the European Medicines Agency (EMA) is also effective for ensuring safety.

Examples of Import-Related Troubles

• Import blocked by customs
• Counterfeit or substandard products received
• Complicated procedures to obtain import permits

Proper Usage and Risk Management of Anesthetic Creams

When using anesthetic creams, it is crucial to follow the package insert and physician’s instructions for proper application. Adhering to the recommended application area and duration is necessary to minimize the risk of side effects. Furthermore, after the procedure, it is important to observe the skin condition and consult a doctor promptly if any abnormalities are noted.

Specific usage instructions include the following:

• Application Area: Apply thinly and evenly only to the treatment area.
• Application Time: Typically, apply for about 30 minutes to 1 hour. The application time varies depending on the product type and treatment content.
• Occlusion: After application, sealing with plastic wrap or film can enhance the anesthetic effect.
• Wipe-off: Before the procedure, completely wipe off the anesthetic cream.

Reported side effects include skin itching, redness, and swelling. Severe side effects, such as allergic reactions and respiratory distress, are extremely rare. In the unlikely event of experiencing any abnormalities, seek immediate medical attention.

Key Points for Risk Management

• Thoroughly confirm the patient’s medical history and allergy history.
• For first-time use, start with a small amount and check for allergic reactions.
• Use high-concentration lidocaine cream under the guidance of a physician.
• Fully explain the risks of side effects to the patient.

Conclusion

Importing anesthetic creams can be an option for obtaining high-concentration lidocaine creams, but various considerations exist, including legal regulations, quality control, and the risk of side effects. To use anesthetic creams safely and effectively, it is essential to thoroughly understand the information explained in this article and to make appropriate judgments and actions. In the field of aesthetic medicine, prioritizing patient safety and providing evidence-based medical care are paramount.
