Pain can be managed through local, regional or systemic approaches depending on the type, intensity and duration of pain. Localized pain often responds well to topical treatments applied directly to the painful area. Common topical regimens include creams, gels and patches containing nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or lidocaine/prilocaine combinations.(1) These provide pain relief locally with few systemic side effects. Onset of relief is relatively quick, within 30-60 minutes, but duration is usually only 2-8 hours depending on the formulation.(1,2)
For regional pain, options include lidocaine patches, lidocaine/tetracaine combination patches or lidocaine/prilocaine cream, which are applied to broader painful areas like low back pain. Duration of relief with these regional patches ranges from 3-12 hours.(2) Systemic pain often requires oral or other routes of administration for treatments to take effect throughout the body. Acetaminophen and NSAIDs like ibuprofen are frequently used as short-acting oral options for mild to moderate acute pain, with onset within 30 minutes and duration of 4-6 hours.(3)
For more severe acute pain or chronic, around-the-clock pain, opioid analgesics play an important role. Immediate-release opioids like oxycodone provide pain relief within 30-60 minutes with a duration of action between 4-6 hours, making them suitable for intermittent or breakthrough pain.(4) However, their shorter duration necessitates more frequent dosing. Extended-release or long-acting opioid formulations like oxycodone ER, morphine sulfate ER or fentanyl patches mitigate peaks and troughs by providing continuous pain relief over 12 hours or longer with once or twice daily dosing.(5) This dosing regimen aims to better match the natural circadian rhythms for chronic pain.
While not directly relieving pain, adjuvant medications may complement pharmacological therapies. For instance, antidepressants and anticonvulsants help manage neuropathic pain by mechanisms independent of pain sensations alone.(6) Non-pharmacological options also contribute as adjunctive or stand-alone treatments. Cognitive-behavioral therapy aims to shift psychological perceptions of pain, reduce stress responses and encourage coping strategies.(7)
In conclusion, an optimal regimen considers acute versus chronic status, time of day, route of administration, onset, duration and side effect profiles to provide the most effective around-the-clock pain management with minimum disruptions to quality of life. Combining pharmacological and non-pharmacological modalities usually results in the best outcomes for both acute and chronic pain conditions.

Summary Notes
Crafting Cannabis Regimens for Varied Pain Types: Strategies and Insights
The development of cannabis regimens for managing different types of pain—ranging from chronic and neuropathic to inflammatory and acute pain—represents a tailored approach to leveraging the analgesic properties of cannabinoids. Understanding the nuances of dosing, cannabinoid ratios, and delivery methods is essential for optimizing pain relief while minimizing potential side effects.
Personalized treatment plans that consider the specific type of pain, patient preferences, and individual responses to cannabis are key to maximizing therapeutic outcomes. The balance between CBD and THC plays a critical role in addressing pain, with certain ratios offering more effective relief for specific conditions, such as neuropathic or inflammatory pain.
Patient experiences and clinical trials provide valuable insights into the efficacy of various cannabis strains and formulations for different pain scenarios, highlighting the importance of patient-centric approaches in cannabis therapy. The role of terpenes and the choice between topical and oral administration further customize the treatment experience, offering options tailored to the nature and location of the pain.
Safety and adherence to cannabis regimens are paramount, with ongoing education for both patients and healthcare providers necessary to navigate the complexities of cannabis-based pain management. Legal and regulatory considerations also influence the accessibility and use of medical cannabis for pain, underscoring the need for advocacy and informed policy-making.
As research continues to evolve, future directions in cannabis pain management promise to refine dosing strategies, develop innovative delivery systems, and further elucidate the mechanisms through which cannabinoids provide analgesia. The goal of enhancing quality of life for individuals experiencing pain drives the continuous exploration of cannabis regimens, aiming to offer effective, safe, and personalized therapeutic options.
