    Coffee and Pain

    How Caffeine May Help (and Cause) Headaches
    WebMD
    October 23, 2017

    Everyone gets headaches from time to time. And most of us have caffeine in what we drink and eat every day. Have you considered whether there's a connection? It's possible for caffeine to both cause and cure a headache.

    How Caffeine Helps
    When your head hurts, you want relief fast. Whether it's a run-of-the-mill tension headache or a migraine, caffeine can help. That's why it's an ingredient in a lot of popular pain relievers. It can make them as much as 40% more effective. Sometimes you can stop the pain in its tracks just by having caffeine alone.

    Caffeine helps reduce inflammation, and that can bring relief. It also gives a boost to common headache remedies. Whether you use aspirin, ibuprofen, or acetaminophen, they work faster and better and keep the pain away for longer when combined with caffeine.

    A very rare condition called hypnic headaches responds especially well to caffeine. These strike older people, waking them in the middle of the night with severe pain. Doctors typically tell people who get these to have a cup of coffee before bed.

    How Caffeine Hurts
    Oddly enough, what makes caffeine effective in pain relief can also cause headaches.

    Since caffeine narrows the blood vessels that surround your brain, when you stop taking it they expand again, and that can cause pain.

    Withdrawal: It's easy for your body to get so used to the effects of caffeine that when you don't have it in your system, you have withdrawal. A headache is one of the symptoms. This can happen when you have caffeine regularly, even as little as a cup of coffee a day.

    Too Much Medication: Caffeine can also a factor in what's known as a medication overuse, or rebound headache. This can happen when you take too much of any kind of pain reliever or take it too often. When the medicine wears off, the pain comes back worse than before. When you combine caffeine with pain relievers this condition is more likely.

    Re: Coffee and Pain

    Why coffee might ease your pain (especially if you're a sleepy mouse)
    Robert H. Shmerling, MD, Faculty Editor, Harvard Health Publishing
    June 12, 2017

    An intriguing new study caught my eye for two reasons. First, there are the fascinating findings of the researchers that could dramatically change our understanding of certain types of pain and how it's treated. More on the research in a moment.

    The other reason this story grabbed my attention is that most of the headlines I read about this research failed to include two important words: "in mice." One article didn't mention the fact that this was an animal study until a full 248 words into the story! Regardless of how interesting the findings are, they deserve a giant asterisk since their relevance to humans is uncertain.

    Sleep-deprived and in pain? Caffeine may work better than ibuprofen
    Researchers studied mice that were either well-rested or sleep-deprived and subjected them to unpleasant stimulation, including contact with a hot plate, cold, or pressure. The intensity and speed of their reaction was measured.

    Here's what the researchers found:

    • Sleep deprivation seemed to increase sensitivity to pain.
    • Restoration of normal sleep reversed the exaggerated pain response.
    • "Wake-promoting agents" (including caffeine and the drug modafinil) also reversed the exaggerated pain response.
    • Ibuprofen and morphine did not have a similar effect as the wake-promoting agents.

    The suggestion here is that sleep deprivation may heighten the perception of pain, and restoration of normal sleep or taking stimulants that increase alertness (as one might experience after drinking coffee) may reduce pain sensitivity in this setting better than common and powerful pain relievers.

    From mice to men… and women
    As mentioned, the relevance of animal studies to humans is not always clear. In fact, it's common that findings in medical studies performed in mice or other animals cannot be replicated in humans. This may be particularly true for something as complicated and subjective as pain.

    The sleep-pain connection
    That said, there is precedent in human disease for a potential connection between pain and sleep deprivation. Fibromyalgia is common in the (human) population and it's marked by chronic, body-wide pain. The cause is unknown, but a leading theory suggests that poor sleep quality may play a role. Treatments that improve sleep quality may help symptoms of fibromyalgia as well.

    What's next?
    The obvious next step is studies in humans. That may not be easy. This trial described continuous monitoring of brain waves in mice by attaching electrodes to their scalps, depriving them of sleep, inflicting pain, and closely observing their response. A similar trial in humans would likely be impossible. And, of course, there are ethical concerns for any study that intentionally inflicts pain on its subjects, whether animal or human.

    This study reminded me of something I learned in medical school. I was taught that one of the most common causes of headache was caffeine withdrawal. An effective "treatment" includes coffee, another caffeine-containing drink or food, or a headache medicine that contains caffeine. But now I'm wondering if the pain-relieving properties of coffee might be less related to caffeine withdrawal and more related to the findings of this study. Maybe wake-promoting agents reverse pain sensitivity in sleep-deprived people, as this study found among mice.

    This novel observation could change how we understand and treat certain types of pain - or it may apply only to mice. Either way the findings are interesting. The big question is: are they important?

    Re: Coffee and Pain

    The Role of Caffeine in Pain Management: A Brief Literature Review
    Alireza Baratloo, Alaleh Rouhipour, Mohammad Mehdi Forouzanfar, Saeed Safari, Marzieh Amiri, and Ahmed Negida, NIH
    June 2016

    Abstract
    Caffeine is the most commonly used psychoactive legal drug in the world. Caffeine's role in controlling pain has received less attention in the past, yet is being increasingly considered. This article briefly reviewed the literature to clarify the role of caffeine as a drug for pain control and attract investigators to this topic.

    Evidence Acquisition:
    The data on Caffeine as an adjuvant therapy or as a main component for pain modulation has been narratively reviewed.

    Results:
    Caffeine plays an important role in pain modulation through their action on adenosine receptors which are involved in nociception. The use of caffeine as adjuvant treatment was well-established in the literature and caffeine is currently available in some over the counter medications. Studies showed controversial results about the interaction between caffeine and morphine for pain relief in patients with terminal stage cancer. As a main component for pain modulation, Caffeine can be used for hypnic headache and postdural puncture headache.

    Conclusions:
    Caffeine has a potential role for pain modulation. Current evidence on caffeine use for migraine and terminal stage cancer is not well-established. Future studies should address the use of caffeine alone for different types of pain with dose escalation and standardization of outcome measurement.

    1.1. Brief History of Caffeine
    Caffeine is an alkaloid named "3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione", with its chemical structure presented in Figure 1. Caffeine is a psychoactive and central nervous system stimulant of the methylxanthine class, that unlike many other psychoactives, is legal all around the world (1). Based on some historical documents, caffeine effects were noticed by a goat herder named Khaldi in southern Abyssinia in the year 850, yet it was extracted for the first time by a German chemist named "Friedlieb Ferdinand Runge" in 1819 (2, 3). Drinks containing caffeine such as tea and coffee became widespread in the 15th and 16th centuries in Arabian countries and in the 18th and 19th centuries in Europe. Nowadays, many people start their day with a cup of coffee. It seems that caffeine's medical effects had been known long before it became a part of regular daily drinks (4). Based on the available scientific evidence, caffeine seems to have minor health risks yet its long-term benefits outweigh the potentially negative short-term health effects. On the other hand, there has not been a lot of research on caffeine, so the risks could be underestimated (5, 6). Consumption of moderate amounts of caffeine is safe for healthy non-pregnant adults. It increases energy, alertness, wakefulness, the accuracy of reactions, and the ability to concentrate and focus attention and decreases fatigue. It also enhances physical performance, short-term memory and cognitive performance (6). Caffeine's role in controlling pain is one of the aspects, which has been less considered in the past yet is being increasingly considered. This article briefly reviewed the literature to clarify the role of caffeine as a drug for pain control and attract investigators to this topic.

    2. Evidence Acquisition
    In this review, we searched PubMed using this query "Caffeine AND Pain". Relevant studies were identified and data on caffeine role as an adjuvant therapy and as a main component for pain modulation was narratively reviewed. Experts from emergency department at Shahid Beheshti University of Medical Sciences were consulted about relevant studies on caffeine and pain management.

    2.1. Caffeine for Pain Management
    Pain management has been studied with various scenarios, and it is still being investigated (7-10). Caffeine's role in pain management is among questionable yet attractive subjects in this regard. The effects of caffeine on pain control are somewhat complex yet understanding such effects is valuable (11). Before addressing the role of caffeine in pain control, first we must be familiar with a substance called adenosine. Adenosine is an inhibitor of neuronal activity in the central nervous system (CNS) and peripheral nervous system (PNS). There are four subtypes of adenosine receptors in human bodies including A1, A2A, A2B, and A3, which are expressed in different parts of the CNS and PNS. The endogenous compound adenosine has various modulatory effects in the central and peripheral nervous systems and its receptors have been known to be involved in antinociception. Enhancing these receptors could lead to arousal, concentration and vigilance. It was discovered that activation of A1 and A2A receptors leads to antinociception in neuropathic pain, nociceptive and inflammatory models (12-14). The structure of caffeine is similar to adenosine and therefore Caffeine compete with adenosine for A2a receptors causing their inhibition. Despite this, caffeine does not alter dopamine release and therefore does not have abuse potential like other adenosine blocking agents, such as cocaine. Understanding these effects, leads to renewed interest as a novel option for pain control. Caffeine could reduce pain sensation through its effects on adenosine receptors (14-18). Caffeine seems to express its direct effect via central blocking of adenosine receptors that influence pain signaling or by blocking of peripheral adenosine receptors on sensory afferents. Antagonism of adenosine receptors, as well as inhibition of cyclooxygenase activity at some sites, may explain caffeine antinociceptive effects and its adjuvant actions (11, 14, 18-20). Interestingly, some researchers claim that genetics can influence the response of individuals to caffeine consumption (21).

    3. Results

    3.1. Role of Caffeine as an Adjuvant Component in Pain Management
    An adjuvant component is something that is added to a medicine to enhance its effectiveness (22). Low doses of caffeine are present as an adjuvant in combination with antidepressant, acetaminophen and non-steroidal anti-inflammatory drugs in many over the counter (OTC) analgesics. Clinical studies have tested and demonstrated its adjuvant analgesic effects since decades ago (23, 24). Its inhibitory effects on A2A and A2B receptors, as well as inhibition of cyclooxygenase activity, have been raised to explain these effects (11). Some reviews found that adding low doses of caffeine to a standard dose of common analgesics enhances pain relief in a small yet important proportion of patients, compared to the analgesic alone. Following a systematic review performed by Derry et al. it was demonstrated that the mentioned effect was small yet statistically significant (22, 25). Derry et al. found 19 eligible studies (involving 7238 participants), which added 100 - 130 mg of caffeine to the main drug such as ibuprofen or paracetamol. Headache, postoperative dental pain and postpartum pain were more prevalent conditions that have been evaluated. No serious adverse event was reported in these studies and their authors claimed that adding 100 mg of caffeine or more to an analgesic could be useful (22, 25).

    Despite what has been said, caffeine in combination with morphine, results in complex outcomes including inhibition or augmentation depending on the disease and the amount and route of administration (11). Researchers in South Korea ran a double-blind randomized, placebo-controlled trial to assess the efficacy of 200 mg of caffeine intravenous infusion once a day for two days as an adjuvant to opioid for pain management in patients with advanced cancer. They assigned 20 patients to the caffeine group and 21 to the placebo group. They concluded that caffeine infusion significantly reduced pain and drowsiness, yet the reduction did not reach clinical significance in patients with advanced cancer undergoing opioid therapy (26).

    It should be noted that based on the current evidence, use of analgesics containing caffeine may be associated with overuse headache, physical dependence, or withdrawal symptoms upon abrupt discontinuation. Therefore, it is generally recommended to use these compounds on a temporary basis for acute pain control (24).

    3.2. Role of Caffeine as the Main Component in Pain Management
    Hypnic headache is a rare benign primary headache disorder, commonly affecting middle-aged patients at night. It was first described in 1988 by Raskin, and adopted by the international classification of headache disorders in 2004 within the "other primary headache" group (code 4.5) (27, 28). Based on a literature review that only consisted of case reports or smaller open case series, it seems that caffeine can be used as a first line agent for acute treatment in this type of headache, and also as a prophylactic agent as well. It was reported that caffeine, even in a cup of strong black coffee or using OTC analgesics containing caffeine, could be an effective treatment option for this type of headache. Some authors even believe that dramatic response to caffeine can be considered as pathognomonic clinical feature in diagnosis of hypnic headache. An appropriate randomized clinical trial is still needed to confirm such claims (29-33).
    Postdural puncture headache (PDPH) is frequently reported as a complication of lumbar puncture and relatively common after spinal anesthesia. Postdural puncture headache pathogenesis is still doubtful, yet it has been assumed to be a consequence of CSF leakage into the epidural space. The hallmark of PDPH is decreased pain score in the supine position and its increase in the upright position (34, 35). Caffeine was first prescribed as a treatment agent for PDPH in 1949 and some investigators have orally used it at different doses, intramuscularly and intravenously (36). Most investigators recommend caffeine as a therapeutic option for treatment of this type of headache. Many studies have been conducted with different roots of administration and dosage, and varying success rates (37, 38). Yucel et al. performed a double-blind randomized clinical trial on this topic. The investigators randomly administered 1000 mL of normal saline with 500 mg of caffeine sodium benzoate or 1000 mL of normal saline during the first 90 minutes after spinal anesthesia administration. They claimed that administrating intravenous caffeine sodium benzoate during and after spinal anesthesia could minimize the rate of PDPH (39). Camann et al. also conducted a double-blind, placebo-controlled trial in this regard. They administered 300 mg of oral caffeine to forty postpartum patients with PDPH and assessed the pain scale immediately before drug administration and four and 24 hours later. They concluded that oral caffeine could be considered for pain relief in PDPH (38). By blocking adenosine receptors, caffeine increases cerebral arterial vasoconstriction, and leads to a decrease in cerebral blood inflow and brain blood volume. On the other hand, caffeine leads to augmentation of cerebrospinal fluid production by stimulating sodium-potassium pumps (35, 40). It seems that caffeine administration is a noninvasive and safe option that may prevent the use of invasive methods such as epidural blood patching, or epidural injection of NaCl 0.9% (35, 41).

    Caffeine is frequently used as an adjuvant therapeutic agent for migraine headache. After new findings about migraine pathophysiology, caffeine landed a more prominent role as a treatment option. Caffeine has the ability to cross the blood-brain barrier, and act as a vasoconstrictor on cerebral vessels. In a pilot study performed in 2014, intravenous administration of 60 mg of caffeine citrate for 61 patients affected by acute migraine attack, was reported as a safe and well-tolerated abortive option at the emergency department (42).

    4. Conclusions
    Caffeine's role in pain control is a subject that has received less attention in the past, yet is being increasingly considered. The current article briefly reviewed the literature to clarify the role of caffeine as a drug for pain control and attract investigators to this topic. For instance, the difference between short and long acting analgesics, when caffeine is added as an adjuvant, has not been considered. Therefore, there are many topics in this regard that willing investigators could explore.
