Goldenberg et al suggest that tramadol works via its serotonin and norepinephrine reuptake inhibition, rather than via its action as a weak opioid receptor agonist.A large study of US people with fibromyalgia found that between 2005 and 2007 37.4% were prescribed short-acting opioids and 8.3% were prescribed long-acting opioids, with around 10% of those prescribed short-acting opioids using tramadol; and a 2011 Canadian study of 457 people with FM found 32% used opioids and two-thirds of those used strong opioids. Topical treatment
Capsaicin has been suggested as a topical pain reliever. Preliminary results suggest that it may improve sleep quality and fatigue, but there are not enough studies to support this claim. Unapproved or unfounded
Sodium oxybate increases growth hormone production levels through increased slow-wave sleep patterns. However, this medication was not approved by the FDA for the indication for use in people with fibromyalgia due to the concern for abuse.The muscle relaxants cyclobenzaprine, carisoprodol with acetaminophen and caffeine, and tizanidine are sometimes used to treat fibromyalgia; however, as of 2015 they are not approved for this use in the United States. The use of NSAIDs is not recommended as first line therapy. Moreover, NSAIDs cannot be considered as useful in the management of fibromyalgia.Very low-quality evidence suggests quetiapine may be effective in fibromyalgia.No high-quality evidence exists that suggests synthetic THC (nabilone) helps with fibromyalgia. Others
A 2013 review found moderate-level evidence on the usage of acupuncture with electrical stimulation for improvement of the overall well-being.
Mucopolysaccharidoses are a group of metabolic disorders caused by the absence or malfunctioning of lysosomal enzymes needed to break down molecules called glycosaminoglycans (GAGs). These long chains of sugar carbohydrates occur within the cells that help build bone, cartilage, tendons, corneas, skin and connective tissue. GAGs (formerly called mucopolysaccharides) are also found in the fluids that lubricate joints. Individuals with mucopolysaccharidosis either do not produce enough of one of the eleven enzymes required to break down these sugar chains into simpler molecules, or they produce enzymes that do not work properly. Over time, these GAGs collect in the cells, blood and connective tissues. The result is permanent, progressive cellular damage which affects appearance, physical abilities, organ and system functioning. The mucopolysaccharidoses are part of the lysosomal storage disease family, a group of more than 40 genetic disorders that result when the lysosome organelle in animal cells malfunctions. The lysosome can be thought of as the cells recycling center because it processes unwanted material into other substances that the cell can utilize. Lysosomes break down this unwanted matter via enzymes, highly specialized proteins essential for survival. Lysosomal disorders like mucopolysaccharidosis are triggered when a particular enzyme exists in too small an amount or is missing altogether. Signs and symptoms
The mucopolysaccharidoses share many clinical features but have varying degrees of severity. These features may not be apparent at birth but progress as storage of GAGs affects bone, skeletal structure, connective tissues, and organs.
