Two preparations of botulinum antitoxins are available for treatment of botulism. Trivalent (A,B,E) botulinum antitoxin is derived from equine sources using whole antibodies. The second antitoxin is Heptavalent (A,B,C,D,E,F,G) botulinum antitoxin, which is derived from equine antibodies which have been altered to make them less immunogenic. This antitoxin is effective against all known strains of botulism.
Onabotulinumtoxin A (trade name Botox) received FDA approval for treatment of chronic migraines on October 15, 2010. The toxin is injected into the head and neck to treat these chronic headaches. Approval followed evidence presented to the agency from two studies funded by Allergan showing a very slight improvement in incidence of chronic migraines for migraine sufferers undergoing the Botox treatment.
BOTOX® Cosmetic targets one of the underlying causes of frown lines, crow’s feet and forehead lines — the repeated muscle contractions from frowning, squinting, smiling and raising the eyebrows over the years. Your specialist will inject these muscles with BOTOX® Cosmetic to temporarily reduce muscle activity. You will begin to notice a visible smoothing of the frown lines between your brows, your crow’s feet lines and your forehead lines.
The co-primary endpoints were the average of the change from baseline in modified Ashworth Scale (MAS) ankle score at Week 4 and Week 6, and the average of the Physician Global Assessment of Response (CGI) at Week 4 and Week 6. The CGI evaluated the response to treatment in terms of how the patient was doing in his/her life using a 9-point scale from -4=very marked worsening to +4=very marked improvement).
BOTOX is administered about every three months, and must be injected at the site of each nerve trigger, relaxing the surrounding muscles so that they won’t compress the nerve and trigger a migraine. It is a potent drug, and we only recommend using it if other preventative treatment options haven’t helped you. It is generally only administered to patients who have at least 14 headaches a month, or don’t respond to other treatments.
I tell my patients that it is not the total price that is important, but how many units are used. For instance, if a patient goes to a spa and pays $150 per area, that may sound like a great deal. However, when the patient ask how long the treatment is supposed to last, the spa responds "2 months". I have seen that many of those less expensive treatments often consist of around 10 units (and therefore carrying a "non-deal" $15 cost per unit!). So, what initially looks like a great bargain, is in fact just a treatment with an inadequate amount of Botox. Always ask your injector how many units they are using, so you can determine what price/unit you are getting. Experienced injectors know that there is no such thing as a standard amount of units, as everyone's facial anatomy and muscular strengths are variable, even from one side of the face to the other.
The toxin itself is released from the bacterium as a single chain, then becomes activated when cleaved by its own proteases. The active form consists of a two-chain protein composed of a 100-kDa heavy chain polypeptide joined via disulfide bond to a 50-kDa light chain polypeptide. The heavy chain contains domains with several functions: it has the domain responsible for binding specifically to presynaptic nerve terminals, as well as the domain responsible for mediating translocation of the light chain into the cell cytoplasm as the vacuole acidifies. The light chain is a zinc metalloprotease and is the active part of the toxin. It is translocated into the host cell cytoplasm where it cleaves the host protein SNAP-25, a member of the SNARE protein family which is responsible for fusion. The cleaved SNAP-25 is unable to mediate fusion of vesicles with the host cell membrane, thus preventing the release of the neurotransmitter acetylcholine from axon endings. This blockage is slowly reversed as the toxin loses activity and the SNARE proteins are slowly regenerated by the affected cell.
Ray Chester, an attorney in Austin who has represented several plaintiffs in lawsuits against Allergan, says that just about all the cases he has handled involved off-label use of the drug. In 2014 a New York couple argued that Botox, which they chose to try off-label to treat their son's cerebral-palsy symptoms, caused life-threatening complications. The family was awarded $6.75 million by a jury. Allergan, which initially planned to appeal, ended up privately settling the case with the family, and the terms of the settlement have been kept confidential.
Above all, I try to be gentle with myself and my children. It’s easier said than done. Mom guilt and migraine guilt weigh heavy on my heart, and I continue to remind myself that I’m doing my best. I give myself a break as I do with my children when they’re having a bad day. I’m patient with them and try to give myself the same respect. As a mom, it seems like my job is never done and that I can always do better. The reality is, no one is perfect, and we all have our flaws. We don’t expect our children to be perfect, and we should not expect ourselves to be. We do what we can when we can and take each day as it comes. I find joy in the smallest things and find that being grateful and mindful remind me off all the blessings I have, despite my unpredictable and chronic migraine attacks.
Sharona Hoffman, professor of law and bioethics at Case Western Reserve University School of Law, says that step therapy is driven by a single motivator: saving costs. Hoffman, who’s written about the legal and ethical implications of step therapy, says that sometimes step therapy can have sensible outcomes, like pushing patients to take generics instead of brand-name drugs. But these policies can also keep doctors from prescribing the more expensive drugs of choice, forcing patients to take medications that are less effective or have worse side effects.

BOTOX blocks neuromuscular transmission by binding to acceptor sites on motor or sympathetic nerve terminals, entering the nerve terminals, and inhibiting the release of acetylcholine. This inhibition occurs as the neurotoxin cleaves SNAP -25, a protein integral to the successful docking and release of acetylcholine from vesicles situated within nerve endings. When injected intramuscularly at therapeutic doses, BOTOX produces partial chemical denervation of the muscle resulting in a localized reduction in muscle act ivity. In addition, the muscle may atrophy, axonal sprouting may occur, and extrajunctional acetylcholine receptors may develop. There is evidence that reinnervation of the muscle may occur, thus slowly reversing muscle denervation produced by BOTOX.
