In the United States, botulinum toxin products are manufactured by a variety of companies, for both therapeutic and cosmetic use. A U.S. supplier reported in its company materials in 2011 that it could "supply the world's requirements for 25 indications approved by Government agencies around the world" with less than one gram of raw botulinum toxin.[66] Myobloc or Neurobloc, a botulinum toxin type B product, is produced by Solstice Neurosciences, a subsidiary of US WorldMeds. AbobotulinumtoxinA), a therapeutic formulation of the type A toxin manufactured by Galderma in the United Kingdom, is licensed for the treatment of focal dystonias and certain cosmetic uses in the U.S. and other countries.[30]
Currently, there are several anti-CGRP treatments undergoing clinical trials. Some of these treatments involve monoclonal antibodies, which reduce the activity of CGRP, potentially leading to fewer migraine attacks. One of these anti-CGRP monoclonal antibodies, erenumab (Aimovig™), has been approved by the Federal Drug Administration (FDA) and is now available for patients. A second agent, fremanezumab (Ajovy™), was approved in September 2018. A week later, the FDA approved galcanezumab (Emgality™), making it the third anti-CGRP treatment currently on the market. Results from the clinical trials involving anti-CGRP antibodies have shown that about 50 percent of patients will have at least a 50 percent reduction in migraine days. “If you think about someone who has 20 migraine days per month, they have a 50 percent chance of having 10 or less migraine days,” Dr. Starling says. “We think that there are even these super-responders who have a 75 percent response rate, as well as super-super-responders who actually go into remission.” The results from these clinical trials are very promising, Dr. Starling adds. “The adverse events have been very minimal and the efficacy has been very good. It’s all looking up.” Dr. Starling says that although these medications are available, what really needs to be looked at is how to make them truly accessible for patients. Erenumab can cost about $7,000 per year without insurance coverage. “Insurance coverage is very, very key for the majority of our patient population,” she says. “Because the medications just came out on the market, there are still a lot of unknowns about insurance coverage.”
Focal Spasticity is a condition in which certain muscles in your body become stiff or tight. It is caused by damage to parts of the central nervous system that control voluntary movements. When this happens, your nerves send continuous messages to your muscles telling them to contract, or tighten. If you or someone you care for has stiffness in the muscles of the elbow, wrist, fingers, thumb, ankle, or toes, it could be Focal Spasticity.1
Of 1242 overactive bladder patients in placebo-controlled clinical studies of BOTOX, 41.4% (n=514) were 65 years of age or older, and 14.7% (n=182) were 75 years of age or older. Adverse reactions of UTI and urinary retention were more common in patients 65 years of age or older in both placebo and BOTOX groups compared to younger patients (see Table 18). Otherwise, there were no overall differences in the safety profile following BOTOX treatment between patients aged 65 years and older compared to youn ger patients in these studies.
The recommended dilution is 200 Units/4 mL or 100 Units/2 mL with preservative -free 0.9% Sodium Chloride Injection, USP (see Table 1). The lowest recommended starting dose should be used, and no more than 50 Units p er site should generally be administered. An appropriately sized needle (e.g., 25-30 gauge) may be used for superficial muscles, and a longer 22 gauge needle may be used for deeper musculature. Localization of the involved muscles with techniques such as needle electromyographic guidance or nerve stimulation is recommended.
Allergan Plc engages in the research, development, and manufacture of pharmaceutical products. It operates through the following business segments: US Specialized Therapeutics; US General Medicine, and International. The US Specialized Therapeutics segment includes sales and expenses relating to branded products within the United States. The US General Medicine segment involves Central Nervous System; Gastrointestinal; Women's Health; Anti-Infectives; and Diversified brands. The International segment comprises of products sold outside the United States. The company was founded on in 1984 and is headquartered in Dublin, Ireland.
When moving a spastic limb through its range of motion, one feels a resistance to movement that increases with the speed at which one moves the limb. This is the definition of spasticity, but other terms such as increased muscle tone, hypertonicity, spastic dystonia, or flexor / extensor spasms are used to describe this resistance. In clinic the term "muscle spasticity" will be used to reduce confusion of terms.
Formation of neutralizing antibodies to botulinum toxin type A may reduce the effectiveness of BOTOX treatment by inactivating the biological activity of the toxin. The critical factors for neutralizing antibody formation have not been well characterized. The results from some studies suggest that BOTOX injections at more frequent intervals or at higher doses may lead to greater incidence of antibody formation. The potential for antibody formation may be minimized by injecting with the lowest effective dose given at the longest feasible intervals between injections.
In the mid-1990s, people who received BOTOX for other conditions reported improvement in their chronic migraine pain. A two-phase study was conducted, treating patients who averaged 20 headache days a month. They received BOTOX injections every twelve weeks for 56 weeks. At the end of that period, 70% of the patients had fewer than half the number of headaches they had before treatment. The FDA officially approved BOTOX to treat chronic migraine in October of 2010. Since then, more than 100,000 patients have been treated.
