Ketamine HCl 2.3%/Lidocaine HCl 2% Topical Gel

The Ketamine HCl 2.3%/Lidocaine HCl 2% Topical Gel is a specialized semisolid formulation designed for targeted application on the skin. This unique preparation combines the analgesic properties of ketamine hydrochloride and the local anesthetic effects of lidocaine hydrochloride in a gel matrix. The product is dispensed through a pump mechanism, which ensures easy and precise dosing. The gel consistency allows for the active ingredients to be absorbed directly at the site of application, providing localized relief.

This formulation is primarily used in the management of neuropathic pain, a chronic pain condition resulting from nerve damage. It is also indicated for the treatment of localized pain syndromes, such as postherpetic neuralgia, complex regional pain syndrome (CRPS), and certain inflammatory skin conditions that involve pain and discomfort. The combination of ketamine and lidocaine in this topical gel offers a synergistic approach, potentially reducing the intensity of pain signals and offering patients a non-systemic treatment option with minimal systemic absorption.

Formula Information

A small arrow pointing down

The Ketamine HCl 2.3%/Lidocaine HCl 2% Topical Gel is a specialized semisolid formulation designed for targeted application on the skin. This gel is compounded at Bayview Pharmacy to ensure a high-quality product that meets the specific needs of patients. The combination of Ketamine, an NMDA receptor antagonist, and Lidocaine, a local anesthetic, provides a dual-action approach to pain management. Ketamine works by blocking certain pain receptors in the brain and spinal cord, while Lidocaine numbs the local area, leading to reduced pain perception.

This topical gel is particularly beneficial for patients suffering from neuropathic pain, a type of chronic pain caused by nerve damage, which is often resistant to standard pain medications. It may also be used for localized pain conditions such as postherpetic neuralgia or complex regional pain syndrome. The gel's consistency allows for easy application and absorption through the skin, delivering the active ingredients directly to the affected area, which can result in fewer systemic side effects compared to oral medications.

The pump mechanism of the container ensures that each dose is measured accurately, which is crucial for maintaining the consistency of treatment and minimizing the risk of overuse or underuse. Patients are advised to apply the gel as directed by their healthcare provider, and it is important to follow their guidance on the amount and frequency of application to achieve optimal results.

For prescribers, it is important to note that the use of this compounded formulation should be based on a thorough evaluation of the patient's condition and consideration of their medical history. Monitoring for potential side effects, such as skin irritation or systemic effects, is recommended. As with all compounded medications, this formulation is made to order and can be tailored to meet the unique needs of individual patients.

If you have any questions about the Ketamine HCl 2.3%/Lidocaine HCl 2% Topical Gel or its suitability for treating specific disease states, please do not hesitate to reach out to us at Bayview Pharmacy. Our team of knowledgeable compounding pharmacists is here to provide guidance and support to both patients and healthcare providers.

Drug Interactions

A small arrow pointing down

The Ketamine HCl 2.3%/Lidocaine HCl 2% Topical Gel is a compounded medication designed for topical application. It is important to consider potential drug interactions when using this formulation. Ketamine, an NMDA receptor antagonist, and lidocaine, a local anesthetic, both have systemic absorption potential, although it is generally low with topical administration. However, when absorbed, ketamine may interact with CNS depressants, such as benzodiazepines, opioids, and alcohol, potentially enhancing sedative, hypnotic, and respiratory depressant effects. Concurrent use of these substances should be approached with caution, and patients should be monitored for signs of excessive CNS depression.

Lidocaine, on the other hand, is a sodium channel blocker and may interact with other local anesthetics or antiarrhythmic drugs, such as mexiletine, leading to additive systemic effects, including CNS and cardiovascular symptoms. Caution is advised when this gel is used in conjunction with other medications that affect cardiac conduction or those that can increase lidocaine levels, such as cimetidine or beta-blockers. Patients with hepatic impairment may have an increased risk of lidocaine toxicity due to reduced clearance.

Additionally, both ketamine and lidocaine may interact with certain antidepressants, such as monoamine oxidase inhibitors (MAOIs) or selective serotonin reuptake inhibitors (SSRIs), potentially leading to increased blood pressure or heart rate. It is crucial to evaluate the patient's current medication regimen for any potential interactions before prescribing this topical gel.

Regarding the treatment of disease states, this topical gel formulation is primarily used for the management of localized pain, including neuropathic pain or pain associated with certain medical procedures. Ketamine's role in the gel is to provide analgesia through NMDA receptor antagonism, which can be beneficial in reducing chronic pain states. Lidocaine provides immediate relief by blocking sodium channels and nerve conduction, which diminishes pain signaling. The combination of these two agents in a topical formulation allows for targeted therapy with a reduced risk of systemic side effects compared to oral or parenteral administration.

It is essential for both patients and prescribers to be aware of the potential for systemic absorption and drug interactions with this formulation. Patients should be advised to inform their healthcare providers of all medications they are taking, including over-the-counter drugs and supplements. If you have any questions or require further information regarding drug interactions with the Ketamine HCl 2.3%/Lidocaine HCl 2% Topical Gel, please reach out to us at Bayview Pharmacy for assistance.

How Does it Work

A small arrow pointing down

The Ketamine HCl 2.3%/Lidocaine HCl 2% Topical Gel is a specialized medication designed for topical application. This semisolid formulation is dispensed through a pump mechanism, which allows for easy and precise dosing. The gel is intended to be applied directly to the skin where it can exert its therapeutic effects locally. The gel base facilitates the delivery of the active ingredients, ketamine and lidocaine, into the skin, providing targeted treatment.

Ketamine HCl, or ketamine hydrochloride, is a medication primarily known for its anesthetic properties. In this topical formulation, ketamine acts as a local anesthetic and analgesic. It works by blocking N-methyl-D-aspartate (NMDA) receptors in the nervous system, which are involved in pain sensation. By inhibiting these receptors, ketamine can effectively reduce the perception of pain in the area of application. Additionally, ketamine has been shown to have anti-inflammatory properties, which may contribute to its pain-relieving effects.

Lidocaine HCl, or lidocaine hydrochloride, is another well-established local anesthetic. It functions by blocking sodium channels in neuronal cell membranes. This action inhibits the initiation and conduction of nerve impulses, leading to a loss of sensation in the area where the gel is applied. When used in combination with ketamine, lidocaine can enhance the overall numbing effect and provide more comprehensive pain relief.

The combination of ketamine and lidocaine in this topical gel is particularly useful for treating localized pain conditions, such as neuropathic pain, which can be associated with conditions like postherpetic neuralgia or diabetic neuropathy. It may also be beneficial for managing pain from conditions like osteoarthritis or certain musculoskeletal injuries. The topical route of administration ensures that the medication acts primarily at the site of pain, minimizing systemic absorption and potential side effects that can occur with oral or injectable forms of these drugs.

It is important for both patients and prescribers to understand that while this topical gel can provide significant pain relief, it should be used as directed by a healthcare professional. The specific formulation of ketamine and lidocaine in this gel has been carefully compounded to ensure stability, efficacy, and safety. Patients should apply the gel as prescribed, and avoid using it on broken or irritated skin. Prescribers should consider the patient's overall medical condition, including any history of sensitivity to anesthetics, when recommending this treatment.

If you have any questions about the Ketamine HCl 2.3%/Lidocaine HCl 2% Topical Gel or its use in treating specific disease states, please reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is here to provide the information and support you need to effectively manage pain with this specialized medication.

Other Uses

A small arrow pointing down

While the primary indication for a Ketamine HCl 2.3%/Lidocaine HCl 2% Topical Gel is often for the management of localized pain, such as neuropathic pain or pain associated with certain dermatological conditions, it may have other therapeutic uses as well. Given the properties of the active ingredients, this formulation may occasionally be used off-label for the alleviation of pain stemming from chronic conditions like post-herpetic neuralgia or complex regional pain syndrome, where nerve dysfunction contributes to the pain experienced by the patient. Additionally, it may provide symptomatic relief for painful musculoskeletal injuries or disorders due to its localized analgesic effect.

Some patients with painful scars, such as keloids or hypertrophic scars, might also experience benefit from the analgesic properties of this gel. The ease of application through the pump mechanism allows for gentle administration to sensitive scar tissue. Moreover, due to the characteristics of the gel base, it could be employed as an adjuvant therapy in the treatment of certain inflammatory skin conditions where pain is a significant complication, following thorough evaluation by a healthcare professional.

It's important to consider that the use of Ketamine HCl 2.3%/Lidocaine HCl 2% Topical Gel for conditions other than those it is primarily indicated for should be under the supervision of a healthcare provider. The pharmacists at Bayview Pharmacy are equipped to discuss the potential benefits and risks associated with off-label uses of this formulation and to provide guidance on how to apply it correctly. If you have any questions or require further information about the potential other uses of this topical gel, please reach out to us for personalized advice and support.
