The median duration of response in study NDO-3, based on patient qualification for re-treatment was 362 days (52 weeks) for the BOTOX 100 Units dose group compared to 88 days (13 weeks) for placebo. To qualify for re-treatment, at least 12 weeks must have passed since the prior treatment, post-void residual urine volume must have been less than 200 mL and patients must have reported at least 2 urinary incontinence episodes over 3 days with no more than 1 incontinence -free day.
* LS mean change, treatment difference and p-value are based on an analysis using an ANCOVA model with baseline weekly endpoint as covariate and treatment group, etiology at study entry (spinal cord injury or multiple sclerosis), concurrent anticholinergic therapy at screening, and investigator as factors. LOCF values were used to analyze the primary efficacy variable.
The frontalis muscle attaches to the skin of the lower forehead and ascends to join the fronto-occipital aponeurosis. The action of the frontalis muscle involves elevation of the eyebrows to produce expressions such as surprise, and can cause deep transverse wrinkles on the forehead. The antagonists for brow depression are the corrugators, procerus, and orbicularis oculi muscles.
Botox, or onabotulinumtoxinA, is used for three main purposes: muscle spasm control, severe underarm sweating and cosmetic improvement. In this article we concentrate on the third use, achieved with the product called Botox Cosmetic, which contains botulinum toxin type A (the active ingredient), human albumin (a protein found in human blood plasma) and sodium chloride.
The range of prices for a single unit of Botox range between $10 and $20 per unit. But the total cost of Botox treatment depends on exactly what you're trying to achieve. For example, the cost of treating horizontal forehead lines may range anywhere from $300 to $700 depending on the factors mentioned above. For other facial areas you may need fewer units.
Food-borne botulism results, indirectly, from ingestion of food contaminated with Clostridium spores, where exposure to an anaerobic environment allows the spores to germinate, after which the bacteria can multiply and produce toxin. Critically, it is ingestion of toxin rather than spores or vegetative bacteria that causes botulism. Botulism is nevertheless known to be transmitted through canned foods not cooked correctly before canning or after can opening, and so is preventable. Infant botulism cases arise chiefly as a result of environmental exposure and are therefore more difficult to prevent. Infant botulism arising from consumption of honey can be prevented by eliminating honey from diets of children less than 12 months old.
Unlike some resurfacing or surgical procedures, after which there is possible pigmentation or scarring, when Botox is done correctly, it can be done on all skin tones. “This is a procedure [and] product that crosses all divides,” says Dr. Matarasso. “Men, women, Caucasian, African-American, Asian, Indian. I don’t think there is a demographic that has not enjoyed the benefit of this product.”
In the third study, 25 patients with chronic migraine were injected with 12.5 doses of botox into each trigger point twice, during a period of 3 months. Frequency (main variable), intensity and scales of migraine crises were recorded one month before and one month after the treatment to compare the changes experienced. In addition, side effects were also recorded during the experiment, and they were found to be mild and temporary.
Normally you would see improvement within a few days. Botox requires two to four days for it to attach to the nerve ending that would normally stimulate the muscle to contract. The maximum effect usually occurs at about 10-14 days. Therefore, whatever effect is obtained two weeks after the injections should be considered the maximum effect that is going to occur.
Some industry insiders say it's not unusual, if still legally murky, for drug-company representatives and doctors to share information with one another about the different ways an approved drug may be used. If a doctor notices that, say, a treatment for crossed eyes also "takes the lines out," he may mention it to the representative from whom he buys the drugs. That rep may share that with another of his clients, and so on.
Now, thanks in large part to off-label use, Botox--the wrinkle smoother that exploded as a cultural phenomenon and medical triumph--is increasingly being drafted for problems that go far beyond the cosmetic. The depression suffered by Rosenthal's patient is just one example on a list that includes everything from excessive sweating and neck spasms to leaky bladders, premature ejaculation, migraines, cold hands and even the dangerous cardiac condition of atrial fibrillation after heart surgery, among others. The range of conditions for which doctors are now using Botox is dizzying, reflecting the drug's unique characteristics as much as the drug industry's unique strategies for creating a blockbuster.
Other side effects of BOTOX® and BOTOX® Cosmetic include: dry mouth, discomfort or pain at injection site, tiredness, headache, neck pain, eye problems: double vision, blurred vision, decreased eyesight, drooping eyelids, swelling of eyelids, dry eyes, and drooping eyebrows. In people being treated for urinary incontinence other side effects include: urinary tract infection, painful urination, and/or inability to empty your bladder on your own. If you have difficulty fully emptying your bladder after receiving BOTOX®, you may need to use disposable self-catheters to empty your bladder up to a few times each day until your bladder is able to start emptying again.
This medication is given by injection by an experienced health care professional. It is injected into the affected muscles (intramuscularly) when treating eye disorders, muscle stiffness/spasms, and wrinkles. When used to prevent migraines, it is injected into the muscles of the head and neck. It is injected into the skin (intradermally) for the treatment of excessive sweating. For the treatment of drooling/excess saliva, this medication is injected into the salivary glands. When treating overactive bladder, it is injected into the bladder.
“ARMR is a longitudinal study. We’re collecting data over time, which will allow us to study changes in headache patterns, health care resource utilization, diagnostic and management strategies, development of co-morbidities and responses to therapies,” Dr. Schwedt says. The registry is comprised of multiple components: The first component is an online platform in which participants fill out a baseline and follow-up questionnaires and clinicians enter the participants’ headache diagnoses. There is also an ARMR headache diary mobile app in which participants share daily information about their migraine attacks, their level of function and their treatment, if any. The third component is a blood sample, which is processed and stored in the ARMR biobank and will be used for genetic analyses. Brain imaging data are collected in the ARMR Neuroimaging Repository, and electronic health record data are pulled and confidentially entered into a centralized ARMR database. “Oftentimes, research is done in silos,” Dr. Schwedt says. “So a group at one institution is doing their own work, collecting their own data, doing their own analysis. And a group at another institution is doing their own work. That isn’t the most efficient way to move forward in the field. We believe creating and sharing data from this large and comprehensive study is really going to improve the efficiency of research in the field.”
If going back for additional treatments three or four times a year sounds like a lot of treatments, the good news is that the more Botox treatments you get, the fewer Botox units you'll need. With each repeat Botox session, the frontalis muscle and other facial muscles surrounding Botox injection sites get a little weaker and become "trained" to not contract.
This product contains albumin, a derivative of human blood. Based on effective donor screening and product manufacturing processes, it carries an extremely remote risk for transmission of viral diseases and variant Creutzfeldt-Jakob disease (vCJD). There is a theoretical risk for transmission of Creutzfeldt-Jakob disease (CJD), but if that risk actually exists, the risk of transmission would also be considered extremely remote. No cases of transmission of viral diseases, CJD or vCJD have ever been identified for licensed albumin or albumin contained in other licensed products.
Migraine with visual aura involves visual effects that usually precede the headache and last at least 5 minutes. The visual aura is usually an expanding blinding spot or visual scintillations (shimmering objects in the visual field). Other aura features include reversible symptoms of speech and language difficulty such as word-finding problems and aphasia (inability to express words or comprehend words), sensory phenomena such as tingling in the extremities extending to the face, motor effects such as weakness, and brainstem problems such as unsteadiness and features of cranial nerve dysfunction. These aura symptoms usually last 5 to 60 minutes, can precede or start during the headache, and can also occur without a headache.
In overactive bladder patients with analyzed specimens from the two phase 3 studies and the open-label extension study, neutralizing antibodies developed in 0 of 954 patients (0.0%) while receiving BOTOX 100 Unit doses and 3 of 260 patients (1.2%) after subsequently receiving at least one 150 Unit dose. Response to subsequent BOTOX treatment was not different following seroconversion in these three patients.
In general, adverse reactions occur within the first week follo wing injection of BOTOX and while generally transient, may have a duration of several months or longer. Localized pain, infection, inflammation, tenderness, swelling, erythema, and/or bleeding/bruising may be associated with the injection. Needle-related pain and/or anxiety may result in vasovagal responses (including e.g., syncope, hypotension), which may require appropriate medical therapy.
Autonomic dysreflexia in patients treated for overactive bladder due to neurologic disease. Autonomic dysreflexia associated with intradetrusor injections of BOTOX® could occur in patients treated for detrusor overactivity associated with a neurologic condition and may require prompt medical therapy. In clinical trials, the incidence of autonomic dysreflexia was greater in patients treated with BOTOX® 200 Units compared with placebo (1.5% versus 0.4%, respectively).
