Brief Summary:

The main objective of this protocol is to determine the effectiveness of using compounded topical pain creams for treating neuropathic, nociceptive, or mixed-pain syndromes. Since these compounded pain creams may be associated with burning or irritation at the application site, and possible systemic effects may present, the secondary objective is to determine the relative satisfaction with the creams. The investigators hypothesis is that the active pain creams may provide significant benefit compared to placebo cream.

3.1 Specific Aims

  1. Specific Aim 1 will determine pain relief following treatment with the appropriate (based on specified pain) compounded topical pain cream or a placebo cream. The investigators hypothesis is that the compounded topical pain creams will provide greater pain relief than placebo creams.
  2. Specific Aim 2 will measure the patient satisfaction with the cream (compound or placebo). The investigators hypothesis is that the compounded topical pain creams will improve patient satisfaction, while the placebo cream will not result in a change in patient satisfaction with their pain treatment.

Detailed Description:
In this study, the investigators are attempting to determine whether compounded topical pain creams are more effective than placebo; as well as measuring the subjects' satisfaction with the compounded pain creams. Three different compounded pain creams (specific to the type of pain being treated) will be used to examine effectiveness and satisfaction in treating neuropathic, nociceptive, or mixed pain syndromes. Up to 399 subjects will be randomized to receive a compounded pain cream or placebo. The type of pain cream to be used will be based on the subjects' pain diagnosis. Pain relief will be measured by a 0-10 Numeric Rating Scale and satisfaction by a 1-5 Likert Satisfaction Scale. The outcome measures will include a 'positive outcome' defined as a two point or greater reduction in average pain (as measured by a NRS) and a score of greater than 3 (on a 1-5 Likert scale measuring satisfaction) at 1-month. The investigators will use the Rand Corporation SF-36 to measure changes in health status during enrollment. Subjects who obtain benefit at 1-month will be followed at 3-months, while those who fail to obtain benefit (i.e., ≥ 2 point reduction in NRS with a greater than 3 Likert satisfaction score) will exit the study to receive alternative care. Patients will be given a pain diary so that their NRS can be calculated at follow up visits.

Arm Intervention/treatment
Placebo Comparator: Neuropathic Pain
Subjects with neuropathic pain will receive a neuropathic pain cream combined of Ketamine 10%/Gabapentin 6%/Clonidine 0.2% and Lidocaine 2% or placebo. They will be told to use the pain cream 3 times per day. Each will receive cream in identical dispensers. Cream is dispensed by rotating the base of the device and each rotation also produces a clicking sound. The number of clicks will be standardized so that all doctors utilize the same prescription depending on the size of the patient's pain location.
Other: Neuropathic pain cream
Subjects will apply the cream to the painful area.

Placebo Comparator: Nociceptive pain
Subjects with nociceptive pain will receive a nociceptive pain cream combined of Ketoprofen 10%/Baclofen 2%/Cyclobenzaprine 2% and Lidocaine 2% or placebo. They will be told to use the pain cream 3 times per day. Each will receive cream in identical dispensers. Cream is dispensed by rotating the base of the device and each rotation also produces a clicking sound. The number of clicks will be standardized so that all doctors utilize the same prescription depending on the size of the patient's pain location.
Other: Nociceptive pain cream
Subjects will apply the cream to the painful area.

Placebo Comparator: Mixed pain
Subjects who have a mixed (nociceptive and neuropathic) pain conditions will receive a mixed pain cream combined of Ketamine 10%/Gabapentin 6%/Diclofenac 3%/baclofen 2%/Cyclobenzaprine 2% and Lidocaine 2% or placebo. They will be told to use the pain cream 3 times per day. Each will receive cream in identical dispensers. Cream is dispensed by rotating the base of the device and each rotation also produces a clicking sound. The number of clicks will be standardized so that all doctors utilize the same prescription depending on the size of the patient's pain location.
Other: Mixed pain cream
Subjects will apply the cream to the painful area.




Primary Outcome Measures :
  1. Numerical Pain Rating Scale (NPRS) 0-10 [ Time Frame: 1 month ]
    The Numerical Pain Rating Scale is a unidimensional measure of pain intensity. It is an 11 point numerical scale (with 0 meaning no pain; and 10 meaning the worst possible pain imaginable) used to assess pain intensity for persons able to self-report.


Secondary Outcome Measures :
  1. Change in Health Status via Rand Corporation SF-36 [ Time Frame: 1 month ]
    The SF-36 is a 36 item Short Form Health Survey that is used to measure changes in health status. It is a set of generic, coherent, and easily administered quality-of-life measures. It is a validated measure of 8 domains including emotional health and physical function, with lower scores translating to greater disability.

  2. 5-point Likert Satisfaction Scale (1-5) [ Time Frame: 1 month ]
    The 5-point Likert Satisfaction Scale is a 5 point scale that is used to measure the subjects opinion/perception of their satisfaction with the compounded product. The scale ranges from 1-5; with 1 denoting "very unsatisfied" and 5 signifying "very satisfied."

  3. Composite outcome determined by combining the subjects average change in pain score measured by the Numerical Pain Rating Scale and their score on the 5-point Likert Satisfaction Scale. [ Time Frame: 1 month ]
    A positive composite outcome was defined as a decrease in average pain of 2 points or greater and a satisfaction score greater than 3.

  4. Numerical Pain Rating Scale (NPRS) 0-10 [ Time Frame: 3 months ]
    The Numerical Pain Rating Scale is a unidimensional measure of pain intensity. It is an 11 point numerical scale (with 0 meaning no pain; and 10 meaning the worst possible pain imaginable) used to assess pain intensity for persons able to self-report.

  5. Change in Health Status via Rand Corporation SF-36 [ Time Frame: 3 Months ]
    The SF-36 is a 36 item Short Form Health Survey that is used to measure changes in health status. It is a set of generic, coherent, and easily administered quality-of-life measures. It is a validated measure of 8 domains including emotional health and physical function, with lower scores translating to greater disability.

  6. 5-point Likert Satisfaction Scale (1-5) [ Time Frame: 3 months ]
    The 5-point Likert Satisfaction Scale is a 5 point scale that is used to measure the subjects opinion/perception of their satisfaction with the compounded product. The scale ranges from 1-5; with 1 denoting "very unsatisfied" and 5 signifying "very satisfied."
