We use the highest quality and FDA approved ingredients when formulating our compounded medications. Our skillfully trained pharmacists will work directly with your healthcare provider to ensure the active ingredients selected for your custom compounded medication are most suitable for your specific needs. Due to the complex nature of pain, the use of multiple agents with complimentary modes of action is often key to the success of transdermal therapy. The ultimate goal is to pick the combination of ingredients that result in the best therapeutic outcome, by working closely with the patient, prescriber, and compounding pharmacist.
1. Acyclovir – For patients with shingles or postherpetic pain, the addition of the antiviral drug acyclovir (in concentrations of 5%) can be very effective. Combine with gabapentin and ketamine for postherpetic pain.
2. Amitriptyline – Amitriptyline is a tricyclic antidepressant agent. It is has been used extensively as an analgesic agent for management of neuropathic pain. Unfortunately, the higher oral doses needed to achieve an analgesic effect cause somnolence and dry mouth, thus limiting patient tolerance and compliance. Side effects are eliminated following topical administration. Amitriptyline is used topically in concentrations of 2-5%.
3. Baclofen – Baclofen is a GABA β receptor agonist. GABA receptor agonists primarily cause muscle relaxation. Baclofen is commercially available as an oral tablet and an intrathecal injection. Baclofen helps reduce painful muscle spasms and clonus in patients with multiple sclerosis and other musculoskeletal conditions. Baclofen is used topically in concentrations of 1-2%. Baclofen is effective but expensive.
4. Gabapentin – Gabapentin (trade name Neurontin® ) is an antiepileptic medication used to control seizures. There have long been recognized similarities with neuronal misfiring in epilepsy and neuropathic pain. Phenytoin, a commonly prescribed anticonvulsant medication, was shown to have analgesic effect in neuropathic pain in 1942. In neuropathic pain, injured nerve fibers may discharge spontaneously – usually at regular intervals – causing significant pain. Gabapentin is a glutamate antagonist. Glutamate is the chemical that stimulates the NMDA pain receptors (see ketamine section below). Blocking glutamate blocks pain transmission. When administered orally (dosage range of 2400-3600mg/day), Gabapentin has shown results in managing pain caused by diabetic neuropathy and postherpetic neuralgia. Topically, the concentrations used are around 5-6%. Gabapentin is very effective and is well tolerated. It should be considered as a mainstay ingredient for all neuropathic pain creams.
5. Ketamine – Ketamine is an N-methyl-D-aspartate (NMDA) receptor antagonist and is topically used in concentrations of 6%. When the pain receptors in the dermatomes start sending signals there is a release of glutamate, which in turn acts on the NMDA receptors in the spinal cord. Activation of NMDA receptors causes the spinal cord neurons to become even more sensitive and responsive to painful stimuli. Ketamine works on receptors in the both the periphery and in the spinal cord. There is also new evidence that blocking NMDA receptors with drugs such as ketamine decreases the development of tolerance to opioids such as morphine, hydrocodone (Vicodin® ), and fentanyl (Duragesic® ). Ketamine is another one of the core drugs used in our topical pain cream formulations.
6. Ketoprofen – Concentrations of 5-10% are commonly prescribed. Ketoprofen is a NSAID and provides excellent relief for acute inflammation and swelling resulting from soft-tissue and skeletal muscle injuries. It should be included as an ingredient whenever inflammation is suspected. Ketoprofen cream is particularly effective for treating arthritis inflammation in the back, hands, knees, or other joints. Ketoprofen cream is also effective for patients with gouty arthritis.
7. Orphenadrine – Orphenadrine is a muscle relaxant with NMDA antagonist activity. Topical concentrations used are 5-10%. It is reported to block pain transmission and cause muscle relaxant effects.
8. Pentoxifylline – Pentoxifylline is a Tumor Necrosis Factor antagonist (TNF-1α). Tumor necrosis factor is a substance produced primarily by monocytes and macrophages in response to inflammatory processes such as arthritis. Topical pentoxifylline reduces inflammation by inhibiting TNF at the cellular level. It is a useful ingredient whenever inflammation is present. Sciatica and neuropathic pain also respond well to pentoxifylline administration. Concentrations used are 5-10%.
9. Tetracaine & Lidocaine – Both of these drugs are local anesthetics that have neuron membrane stabilizing effects. Lidocaine is currently available as a 5% transdermal patch (Lidoderm® ) approved for management of postherpetic neuralgia. Tetracaine concentrations used in the pain formulations are 1-2%. Lidocaine concentrations used are 2-5%.
10. Diclofenac - A commonly used topical NSAID used under the trade name Voltaren™ Gel. Concentrations of 1-3% are commonly prescribed. Diclofenac is a NSAID and provides excellent relief for acute inflammation and swelling resulting from soft-tissue and skeletal muscle injuries. Diclofenac is particularly effective for treating arthritis inflammation in the back, hands, knees, feet, or other joints. Diclofenac cream is also effective for patients with gouty arthritis.
