1. Botulinum Toxin A injections, Botox, Dysport, Xeomin, MyoBloc


Botulinum toxin is a protein and neurotoxin produced by the bacterium Clostridium botulinum. It is the most acutely lethal toxin known, with an estimated human median lethal dose (LD-50) of 1.3–2.1 ng/kg intravenously or intramuscularly and 10–13 ng/kg when inhaled. Botulinum toxin (BTX) can cause botulism, a serious and life-threatening illness in humans and animals. Three forms of botulinum toxin type A (Botox, Dysport and Xeomin) and one form of botulinum toxin type B (MyoBloc) are available commercially for various cosmetic and medical procedures. The toxin works only on each muscle injected, so it may not be the best option for multiple muscles. The injections must be repeated at frequent intervals. The body can create antibodies against the medication which can neutralize the effects.  Drugs.com.

Diazepam and Lioresal offered partial pain relief. Paraspinal muscle administration of botulinum toxin A reduced the tone of paraspinal and thigh muscles significantly and resulted in marked improvement of ambulation and cessation of pain.

BTA administration significantly reduced rigidity and stopped the spasms in all limbs. Following BTA injection on one side, the spasm frequency decreased bilaterally possibly because of the spread of hematogenous toxin.

Preliminary data have been obtained in patients with cervical or thoracolumbar myofascial pain syndrome, chronic low back pain, piriformis muscle syndrome, tennis elbow, and stiff person syndrome. At present, the effects of botulinum toxin and its use for pain relief. remain controversial.

   

2. Cannabinoids, Sativex, Nabilone, Cesamet, Dronabinol, Epidiolex


The term ‘endocannabinoid’ – originally coined in the mid-1990s after the discovery of membrane receptors for the psychoactive principle in cannabis, Delta9-tetrahydrocannabinol and their endogenous ligands – now indicates a whole signalling system that comprises cannabinoid receptors, endogenous ligands, and enzymes for ligand biosynthesis and inactivation. This system seems to be involved in an ever-increasing number of pathological conditions. With novel products already being aimed at the pharmaceutical market little more than a decade since the discovery of cannabinoid receptors, the endocannabinoid system seems to hold even more promise for the future development of therapeutic drugs.


The most psychoactive cannabinoid found in the cannabis plant is tetrahydrocannabinol (or delta-9-tetrahydrocannabinol, commonly known as THC). Other cannabinoids include delta-8-tetrahydrocannabinol, cannabidiol (CBD), cannabinol (CBN), cannabicyclol (CBL), cannabichromene (CBC) and cannabigerol (CBG); they have less psychotropic effects than THC, but may play a role in the overall effect of cannabis. The most studied are THC, CBD and CBN. CBD is considered to have a wider scope of medical applications than tetrahydrocannabinol (THC). An orally-administered liquid containing CBD has received orphan drug status in the US, for use as a treatment for dravet syndrome. Drugs.com.

“Clinical experience with cannabis derivatives in patients with multiple sclerosis is accumulating steadily, but there is no current literature about its efficacy for SPS. Because MS and SPS share some neurological symptoms such as spasticity and rigidity, it is thought that THC-CBC can be an option for SPS patient. Our case report suggests that THC-CBD oromucosal spray is an alternative treatment for patients with refractory SPS, and further validation is appropriate.”

3. Clomipramine (SSRI),  Anafranil


Clomipramine is a tricyclic antidepressant (TCA). Clomipramine withdrawal can be severe. Clomipramine is a highly selective (200x over norepinephrine) inhibitor of serotonin reuptake. It is also an antagonist/inverse agonist at the histamine H1 receptor, the muscarinic acetylcholine receptors and the α1 adrenergic receptor. These last three actions likely contribute to its adverse effects. Drugs.com.

Link to article


“Clomipramine injection severely aggravated the clinical symptoms whereas diazepam, clonidine, and tizanidine decreased both muscular stiffness and abnormal exteroceptive reflexes. The hypothesis is put forward that the stiff-man syndrome is a disorder of descending brain-stem systems which exert a net inhibitory control on axial and limb girdle muscle tone as well as on exteroceptive reflex transmission.”


4. Clonidine, Catapres, Kapvay, Nexiclon, Clophelin


Clonidine is a sympatholytic medication used to treat high blood pressure, attention-deficit/hyperactivity disorder, anxiety disorders, withdrawal (from either alcohol, opioids, or smoking), migraine, menopausal flushing, diarrhea, and certain pain conditions. It is classified as a centrally acting α2 adrenergic agonist and imidazoline receptor agonist. Drugs.com.

5. Interferon


Interferons (IFNs) are proteins made and released by host cells in response to the presence of pathogens such as viruses, bacteria, parasites, or tumor cells. In a typical scenario, a virus-infected cell will release interferons causing nearby cells to ramp up their anti-viral defenses. IFNs belong to the large class of glycoproteins known as cytokines, molecules used for communication between cells to trigger the protective defenses of the immune system that help eradicate pathogens. Interferons are named for their ability to "interfere" with viral replication by protecting cells from virus infection. IFNs also have other functions: they activate immune cells, such as natural killer cells and macrophages; they increase host defenses by up-regulating antigen presentation by virtue of increasing the expression of major histocompatibility complex (MHC) antigens.


Interferon beta-1a and interferon beta-1b are used to treat and control multiple sclerosis. This treatment is effective for reducing attacks in relapsing-remitting multiple sclerosis and slowing disease progression and activity in secondary progressive multiple sclerosis. Interferon therapy is used (in combination with chemotherapy and radiation) as a treatment for some cancers. Drugs.com

We describe the case of a 66-year-old man with chronic hepatitis C who developed type 1 diabetes mellitus (T1DM) and thyroid autoimmunity during Interferon α (INFα) therapy and then stiff-person syndrome (SPS). This is the first reported case in which SPS has appeared as complication of IFNα therapy.


6. L-Dopa, Sinemet, Parcopa, Atamet, Stalevo, Madopar, Prolopa.


L-3,4-dihydroxyphenylalanine) is a chemical that is made and used as part of the normal biology of humans, some animals and plants. Some animals and humans make it via biosynthesis from the amino acid L-tyrosine. L-DOPA is the precursor to the neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline) collectively known as catecholamines. L-DOPA can be manufactured and in its pure form is sold as a psychoactive drug with the INN levodopa;  As a drug it is used in the clinical treatment of Parkinson's disease and dopamine-responsive dystonia. Drugs.com.

“ A case of Stiffman syndrome was followed for several years. A trial with L-dopa was performed after diazepam withdrawal. All-night polygraphic monitorings of the patient’s sleep under diazepam, under no drugs, and under L-dopa were performed. An analysis of sleep stages and electromyographic changes was obtained. A new benzodiazepine (Ro 054023) was tried after L-dopa.”


7. Milacemide


Milacemide is a MAO-B inhibitor and glycine prodrug. It has been studied for its effects on human memory and as a potential treatment for the symptoms of Alzheimer's disease. Early clinical trials, however, showed no positive results. The drug research now is abandoned.

“We investigated the therapeutic effects of milacemide in seven patients with myoclonus and three patients with the stiff-person syndrome in an open-label trial. Milacemide was initiated at 800 mg/day and was gradually increased to a maximum dosage of 2,400 mg/day. No significant improvement occurred in the 10 patients.”

We performed a therapeutic trial with the glycine precursor, milacemide, on 10 patients with intractable movement disorders. Six had myoclonus of various etiologies and one each had progressive supranuclear palsy, Filipino X-linked dystonia with parkinsonism, painful legs and moving toes, and stiff-person syndrome. Milacemide was initiated at a dose of 2,400 mg/day, orally, and increased gradually to a maximum of 4,800 mg/day. No clear-cut observable improvement occurred. There were no serious adverse effects.
