Formula Information

A small arrow pointing down

This formulation is a compounded topical gel containing Amitriptyline HCl 7%, Gabapentin 10%, and Ketamine HCl 5%. It is a semisolid formulation that is dispensed through a pump mechanism, which allows for easy and precise application on the skin. The gel-like consistency of the formulation ensures targeted treatment or absorption of the active ingredients.

Amitriptyline HCl 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. Gabapentin is an anticonvulsant and nerve pain medication that is used to treat nerve pain conditions. It works by stabilizing electrical activity in the brain and affects the way the nerves send messages to the brain. Ketamine HCl is a powerful anesthetic that provides pain relief by blocking certain receptors in the brain.

This combination of medications in a topical gel form is designed to provide targeted relief from various disease states. The topical application allows for direct delivery of the medication to the affected area, reducing systemic side effects often associated with oral medications.

It is important for patients and prescribers to understand that this is a compounded medication, meaning it is made specifically for the patient based on a doctor's prescription. It is not a commercially available product and should be used under the supervision of a healthcare provider. As with any medication, it may cause side effects, and patients should report any unusual symptoms to their healthcare provider immediately.

Drug Interactions

A small arrow pointing down

This topical gel formulation contains Amitriptyline HCl, Gabapentin, and Ketamine HCl. These active ingredients are used in combination to manage various pain conditions, including neuropathic pain, post-herpetic neuralgia, and fibromyalgia. Amitriptyline is a tricyclic antidepressant that works by increasing the levels of certain chemicals in the brain that help improve mood, sleep, and the body's response to pain. Gabapentin is an anticonvulsant that is also used to treat nerve pain. It works by decreasing abnormal excitement in the brain. Ketamine is a general anesthetic that works by blocking certain receptors in the brain to maintain a state of anesthesia and reduce pain.

It's important to be aware of potential drug interactions when using this formulation. Amitriptyline can interact with MAO inhibitors, leading to serious, potentially fatal side effects. If you are currently taking or have taken MAO inhibitors within the last 14 days, inform your healthcare provider. Additionally, the sedative effects of Amitriptyline can be enhanced when used in combination with other CNS depressants such as alcohol, barbiturates, or benzodiazepines.

Gabapentin can interact with antacids containing aluminum or magnesium, as they can decrease the absorption of Gabapentin. It is recommended to take Gabapentin at least 2 hours after taking an antacid. Also, Gabapentin's side effects such as drowsiness or dizziness may increase if taken with alcohol or other CNS depressants.

Ketamine can interact with a number of medications, including barbiturates, benzodiazepines, and opioids, potentially leading to increased sedation and respiratory depression. It can also interact with medications that affect liver enzymes, potentially altering the metabolism and effectiveness of Ketamine.

It's crucial to inform your healthcare provider of all medications, supplements, and herbal products you are currently taking before starting this treatment. This includes over-the-counter medications and recreational drug use. Also, inform your healthcare provider if you have any history of liver or kidney disease, heart conditions, or mental health disorders, as these may affect the safety and effectiveness of this formulation.

Remember, this formulation is for topical use only and should not be ingested or applied to open wounds or damaged skin. If you experience any unusual side effects or if your condition does not improve or worsens, contact your healthcare provider immediately.

How Does it Work

A small arrow pointing down

The Amitriptyline HCl 7%/Gabapentin 10%/Ketamine HCl 5% Topical Gel is a unique formulation that combines three active ingredients, each with its own mechanism of action, to provide targeted relief from various disease states. This semisolid formulation is dispensed through a pump mechanism, which allows 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 HCl is a tricyclic antidepressant that works by increasing the levels of certain chemicals in the brain that help elevate mood. In this formulation, it is used for its analgesic properties to help relieve pain. It is believed to work by blocking the reuptake of serotonin and norepinephrine in the brain, thereby increasing their availability. This can help to alter the perception of pain.

Gabapentin is an anticonvulsant that is used in this formulation for its ability to relieve nerve pain. It works by stabilizing electrical activity in the brain which prevents the pain signals from reaching the nervous system. This can help to reduce the sensation of pain in areas of the body where the gel is applied.

Ketamine HCl is a powerful anesthetic that is used in this formulation for its ability to provide rapid pain relief. 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 HCl can help to reduce the sensation of pain.

This combination of Amitriptyline HCl, Gabapentin, and Ketamine HCl in a topical gel formulation allows for targeted treatment of various disease states. The topical application allows for the active ingredients to be absorbed directly into the affected area, providing targeted relief from pain.

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 if you are experiencing any side effects, please reach out to us at Bayview Pharmacy. Our team of knowledgeable compounding pharmacists is here to help.

Other Uses

A small arrow pointing down

This unique compounded formulation of Amitriptyline HCl 7%, Gabapentin 10%, and Ketamine HCl 5% is primarily known for its utility in managing pain related conditions including neuropathic pain, postherpetic neuralgia, and fibromyalgia. However, it can also be employed for other therapeutic purposes.

Being a topical gel formulation, it is capable of providing localized treatment, which can be beneficial for other forms of chronic and migraine headaches, by applying it to the nape of the neck or temples. Some patients and prescribers have found success using this as an adjunct treatment for complex regional pain syndrome (CRPS) due to its combination of neuropathic pain-targeting ingredients.

This compound could also be used for targeted pain relief in specific body locations such as for musculoskeletal pain, arthritis, and painful diabetic peripheral neuropathy. The non-systemic nature of this formulation results in fewer systemic side effects, making it a good alternative for patients who may have contraindications or intolerances to oral medication.

Because of Amitriptyline's sedative effects, the compound may find use in managing some symptoms of insomnia. However, this indication should be used with caution as the drug could have other systemic effects despite its topical application. Therefore, this use would be off-label and at the discretion of the prescribing provider.

Finally, since Ketamine has shown promise in the treatment of depressive symptoms, there is potential for this formulation to be explored in managing select cases of refractory depression, although it is important to note that the evidence is sparse, and this use will be very off-label.

As every medical condition is unique, it is vital to understand that this formulation may not be beneficial for every patient. Proper consultation with a healthcare provider is necessary before starting any new treatment. If you have any questions about this compounded formulation, reach out to the expert team of compounding pharmacists at Bayview Pharmacy. We are here to provide in-depth knowledge and personalized advice for both patients and prescribers.

Enter the formula as a compound

Compounded preparations have no NDC, so this formula will not appear in your EHR's drug search. Use your system's compound, non-formulary, or free-text prescription entry and name the preparation exactly as written in step 3. If your EHR forces you to pick a listed drug, pick the closest entry for the active ingredient and put the full formula in the prescription body (the Sig or directions field), not in Notes to Pharmacy.

Compounded preparations have no NDC and will not appear in your drug search. For EPCS to validate, select a drug entry your EHR recognizes as controlled, usually the bulk powder entry for the active ingredient (for example Ketamine (bulk) powder, not a branded product), then put the full formula from step 3 in the prescription body. A free-text entry that does not validate as controlled will be rejected by your EPCS module.
