Formula Information

A small arrow pointing down

This formulation is a compounded transdermal gel containing Amitriptyline 10%, Ketamine 5%, Lidocaine 5%, and Prilocaine 5%. It is a semisolid formulation that is dispensed through a pump mechanism, allowing for easy and precise application on the skin. The gel-like consistency ensures that the active ingredients are absorbed effectively into the skin for targeted treatment.

Amitriptyline is a tricyclic antidepressant that is used in this formulation for its analgesic properties. It works by increasing the levels of certain chemicals in the brain that help elevate mood and reduce the sensation of pain. Ketamine, on the other hand, is a powerful anesthetic that provides rapid pain relief by blocking the NMDA receptors in the brain and spinal cord, which are involved in transmitting pain signals.

Lidocaine and Prilocaine are both local anesthetics that work by causing temporary numbness/loss of feeling in the skin and surrounding tissues. They are used in this formulation to provide immediate, localized pain relief. The combination of these four active ingredients provides both immediate and long-term pain relief, making this formulation particularly effective for managing chronic pain conditions.

This formulation can be used to treat a variety of disease states that involve chronic pain, including neuropathic pain, fibromyalgia, post-herpetic neuralgia, and certain types of arthritis. It can also be used to manage pain associated with certain types of cancer, as well as pain resulting from nerve damage due to diabetes (diabetic neuropathy).

It is important to note that this formulation should be used exactly as prescribed by your healthcare provider. The dose and frequency of use will depend on the individual patient's condition and response to treatment. Side effects may include skin irritation at the application site, dizziness, drowsiness, or changes in mood or behavior. If any of these side effects persist or worsen, contact your healthcare provider immediately.

As compounding pharmacists, we are committed to providing personalized medication solutions to meet the unique needs of each patient. If you have any questions about this formulation or how it can be used to manage your specific condition, please do not hesitate to reach out to us at Bayview Pharmacy. We are here to help.

Drug Interactions

A small arrow pointing down

This compounded formulation contains Amitriptyline, Ketamine, Lidocaine, and Prilocaine. These active ingredients work synergistically to provide pain relief, particularly for neuropathic pain conditions. Amitriptyline is a tricyclic antidepressant that has been shown to reduce pain signals in the central nervous system. Ketamine is an NMDA receptor antagonist that can help reduce neuropathic pain and potentiate the effects of opioids. Lidocaine and Prilocaine are local anesthetics that provide topical numbing to the application area, reducing pain signals at the site.

While this formulation is designed to minimize systemic absorption and focus treatment at the site of application, some drug interactions may still occur. Amitriptyline can interact with MAO inhibitors, SSRIs, anticholinergic drugs, and certain heart medications. It's important to inform your healthcare provider if you're taking any of these medications. Additionally, consuming alcohol or grapefruit juice while using this formulation may increase the concentration of Amitriptyline in your blood, potentially leading to increased side effects.

Ketamine may interact with CNS depressants, opioids, and certain psychiatric medications. It's crucial to inform your healthcare provider if you're taking any of these medications. Lidocaine and Prilocaine may interact with other local anesthetics or medications metabolized by the liver. If you're using other topical medications, it's important to apply them at different times to avoid potential interactions.

It's also important to note that this formulation should not be used in patients with a known allergy to any of the ingredients. Patients with certain heart conditions, liver disease, or a history of seizures should use this medication with caution. Pregnant or breastfeeding women should consult their healthcare provider before using this formulation.

As with any medication, it's important to use this formulation as directed by your healthcare provider. If you experience any unusual side effects, discontinue use and contact your healthcare provider immediately. Always inform your healthcare provider of all medications you're currently taking, including over-the-counter drugs, supplements, and herbal products, to avoid potential interactions.

If you have any questions about this formulation or its potential interactions, please don't hesitate to reach out to us at Bayview Pharmacy. Our knowledgeable team of compounding pharmacists is here to assist you.

How Does it Work

A small arrow pointing down

The Amitriptyline 10%/Ketamine 5%/Lidocaine 5%/Prilocaine 5% Transdermal Gel is a unique formulation that combines four active ingredients, each with its own mechanism of action, to provide targeted relief from various disease states. This formulation is designed to be applied topically, directly to the skin, where it can be absorbed into the body to exert its therapeutic effects.

Amitriptyline, a tricyclic antidepressant, works by increasing the levels of certain chemicals in the brain that help elevate mood and reduce pain perception. In this formulation, it is used for its analgesic properties, particularly in the management of neuropathic pain. It is believed to work by blocking the reuptake of serotonin and norepinephrine, two neurotransmitters involved in pain signaling.

Ketamine, an NMDA receptor antagonist, is used for its potent analgesic and anti-inflammatory properties. It works by blocking the NMDA receptors in the brain and spinal cord, which play a key role in transmitting pain signals. By blocking these receptors, ketamine can help reduce the perception of pain.

Lidocaine and Prilocaine are both local anesthetics that work by blocking sodium channels in the nerve cells, preventing the initiation and conduction of nerve impulses. This results in a loss of sensation in the area where the gel is applied, providing immediate relief from pain.

The combination of these four active ingredients in a transdermal gel formulation allows for targeted application and absorption, providing relief directly at the site of pain. The gel formulation also allows for a controlled release of the active ingredients, ensuring a sustained therapeutic effect.

This formulation is particularly useful in the management of conditions such as neuropathic pain, post-herpetic neuralgia, fibromyalgia, and other conditions where pain is a predominant symptom. It can also be used in the management of localized pain conditions such as osteoarthritis.

As with any medication, it is important to use this formulation as directed by your healthcare provider. If you have any questions about this formulation or its use, please do not hesitate to reach out to us at Bayview Pharmacy. Our team of knowledgeable compounding pharmacists is always here to help.

Other Uses

A small arrow pointing down

Aside from its primary use for pain management and nerve-related disorders, the Amitriptyline 10%/Ketamine 5%/Lidocaine 5%/Prilocaine 5% transdermal gel may also serve other therapeutic functions. Under the direction of a healthcare provider, this formulation can potentially be used to manage conditions such as certain types of chronic itch, post-herpetic neuralgia, and peripheral neuropathy.

By delivering analgesic, anesthetic, and antidepressant compounds directly through the skin into the area of concern, this formulation can potentially alleviate discomfort arising from these conditions. The inclusion of Amitriptyline, a tricyclic antidepressant, offers potential benefits for those suffering from persistent itch, often associated with conditions such as dermatitis or pruritus. Additionally, the combination of Lidocaine and Prilocaine, both local anesthetics, may help soothe neuralgia and neuropathy-associated pain by numbing the targeted area, thus reducing nerve signal transmission to the brain.

Moreover, Ketamine, an NMDA receptor antagonist, may play a crucial role in managing chronic pain and hastening the recovery of nerve function in patients with peripheral neuropathy. That said, the off-label use of this transdermal gel should be strictly supervised by a healthcare provider, as several factors such as the patient's overall health condition, severity and type of disease, drug interactions, and patient's response to treatment need to be considered.

Patients should also be made aware that while there are potentially beneficial other uses of this transdermal gel, its use for non-indicated conditions may not be covered by insurance. As with any medication, potential side-effects, interactions, and contraindications should be discussed prior to its use. As always, if there are any questions regarding this formulation and its use, we at Bayview Pharmacy are here to help, so please feel free to reach out to us.
