Formula Information

A small arrow pointing down

This formulation is a compounded transdermal gel containing Amitriptyline 5%, Gabapentin 5%, Ketamine 5%, and Ketoprofen 10%. It is a semisolid formulation 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 directly into the targeted area, providing localized relief.

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. 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 affecting the way the nerves send messages to the brain.

Ketamine is a powerful anesthetic that provides pain relief by blocking certain receptors in the brain. It is used in this formulation for its potent analgesic effects. Ketoprofen is a nonsteroidal anti-inflammatory drug (NSAID) that reduces inflammation and pain in the body by reducing the production of certain substances that cause inflammation and pain.

This formulation is used to treat various disease states that involve chronic pain, such as neuropathic pain, fibromyalgia, and complex regional pain syndrome (CRPS). By combining these four active ingredients, this formulation provides a multi-modal approach to pain management, targeting different pain pathways to provide comprehensive relief.

Patients using this formulation should apply it as directed by their healthcare provider, typically to the affected area 1-3 times daily. It is important to wash hands before and after application and to avoid contact with eyes, mouth, and other mucous membranes. Side effects may include skin irritation at the application site, drowsiness, dizziness, and dry mouth. If these side effects persist or worsen, contact your healthcare provider immediately.

Prescribers should consider this formulation for patients who have not responded to traditional oral pain medications or who cannot tolerate them due to side effects. As this is a compounded medication, it can be customized to meet the specific needs of each patient, including adjusting the concentrations of the active ingredients or changing the base of the gel to accommodate patient preferences or allergies.

Drug Interactions

A small arrow pointing down

This compounded formulation contains Amitriptyline, Gabapentin, Ketamine, and Ketoprofen. These medications are often used together in a transdermal gel to manage chronic pain conditions, such as neuropathic pain, fibromyalgia, and complex regional pain syndrome. The gel is applied topically, allowing for targeted treatment and potentially reducing systemic side effects.

Amitriptyline is a tricyclic antidepressant that can help reduce chronic pain. Gabapentin is an anticonvulsant that can also help manage neuropathic pain. Ketamine is a NMDA receptor antagonist that can provide pain relief, and Ketoprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can reduce inflammation and pain.

It's important to be aware of potential drug interactions with this formulation. Amitriptyline can interact with other medications that affect serotonin levels, such as selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), and monoamine oxidase inhibitors (MAOIs). This can increase the risk of serotonin syndrome, a potentially life-threatening condition.

Gabapentin can interact with antacids containing magnesium or aluminum, as they can reduce the absorption of Gabapentin. It's recommended to take Gabapentin at least 2 hours after taking an antacid.

Ketamine can interact with other central nervous system depressants, including alcohol, 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 of Ketamine.

Ketoprofen can interact with other NSAIDs, increasing the risk of gastrointestinal bleeding. It can also interact with blood thinners, such as warfarin, and certain blood pressure medications, such as ACE inhibitors and diuretics.

It's important to inform your healthcare provider of all medications you're currently taking, including prescription drugs, over-the-counter medications, and dietary supplements. This will help your healthcare provider to manage potential drug interactions.

Patients should also be aware of potential side effects of this formulation, which can include skin irritation at the application site, drowsiness, dizziness, and gastrointestinal symptoms. If you experience any severe or persistent side effects, contact your healthcare provider immediately.

How Does it Work

A small arrow pointing down

This formulation combines four active ingredients: Amitriptyline, Gabapentin, Ketamine, and Ketoprofen, each with a unique mechanism of action to provide a comprehensive approach to pain management. The transdermal gel is designed to be applied directly to the skin, allowing for targeted treatment and absorption of these active ingredients.

Amitriptyline is a tricyclic antidepressant that works by increasing the levels of certain chemicals in the brain that help improve mood, pain, and sleep. While it's primarily used to treat depression, it's also found to be effective in managing certain types of pain, particularly neuropathic pain. It's thought to work by blocking the reuptake of serotonin and norepinephrine, two neurotransmitters in the brain, thereby increasing their levels and enhancing their pain-relieving effects.

Gabapentin is an anticonvulsant that's often used to treat seizures and nerve pain. It works by calming down nerve activity, thereby reducing pain sensation. It's particularly effective in treating neuropathic pain, such as that caused by shingles or diabetic neuropathy.

Ketamine is a powerful anesthetic that's used to induce and maintain anesthesia. It works by blocking the NMDA receptor, a type of glutamate receptor in the brain and spinal cord. This action inhibits the transmission of pain signals to the brain, providing potent analgesic effects. In this formulation, it's used in a much lower concentration than what's typically used for anesthesia, providing pain relief without causing a loss of consciousness.

Ketoprofen is a nonsteroidal anti-inflammatory drug (NSAID) that works by reducing hormones that cause inflammation and pain in the body. It's often used to relieve pain, reduce inflammation, and lower fever. In this formulation, it provides local anti-inflammatory and analgesic effects, helping to reduce pain and swelling in the area where the gel is applied.

The transdermal gel formulation allows for targeted application and absorption of these active ingredients. By applying the gel directly to the area of pain, it allows for a higher concentration of the medication to be delivered to the affected area, while minimizing systemic absorption and potential side effects. The pump mechanism facilitates easy and precise application, ensuring that the correct dose is applied each time.

This formulation is particularly useful in treating various disease states that involve pain, including neuropathic pain, inflammatory pain, and certain types of chronic pain. It provides a comprehensive approach to pain management, combining the unique mechanisms of action of four different medications to provide potent and targeted pain relief.

Other Uses

A small arrow pointing down

This formulation, including Amitriptyline, Gabapentin, Ketamine, and Ketoprofen, is commonly prescribed for a variety of pain conditions. The synergy of these ingredients allows for a multi-faceted approach to targeting neural pain signals, helping to reduce discomfort while minimizing systemic drug exposure.

In addition to its use for pain management, the transdermal gel format allows the potent ingredients to be directly applied to the targeted area, thus reducing the overall systemic exposure and potential side effects. This can be a more desirable option for patients who cannot tolerate oral forms of these medications or prefer a more targeted therapy. The tightening of the skin upon drying may also provide a secondary physical barrier that can reduce some types of pain or discomfort.

Another use for this compound might be refractory pruritus, or itching that doesn't respond to regular treatments. The Amitriptyline component has anti-itch properties that can be useful in managing this condition, while Gabapentin has been reported to help alleviate pruritus in some cases, especially if it's neuropathic in nature. Patients with chronic diseases such as liver disease, kidney disease, or cancer often experience persistent pruritus, and this compound may provide a novel option for these patients.

This complex formulation may also be used off-label in the management of trigeminal neuralgia or other neuropathic conditions where traditional oral medications have not had sufficient effectiveness, or where side effects have limited use. Please note that all off-label use should be discussed with a healthcare provider and weighed against the potential risks and benefits.

Please remember, this formulation is not suitable for use in all patients. It may not be advised for individuals with allergies or sensitivities to any of the components in the gel, as well as those with certain medical conditions. It should not be applied to damaged or broken skin, as the drug could enter the bloodstream at a higher rate. The gel should also be carefully handled to prevent contact with sensitive areas such as the eyes, nose, and mouth.
