Two double-blind, placebo-controlled, randomized, multi-center clinical studies were conducted in patients with urinary incontinence due to detrusor overactivity associated with a neurologic condition who were either spontaneously voiding or using catheterization (Studies NDO-1 and NDO-2). A total of 691 spinal cord injury (T1 or below) or multiple sclerosis patients, who had an inadequate response to or were intolerant of at least one anticholinergic medication, were enrolled. These patients were randomized to receive either 200 Units of BOTOX (n=227), 300 Units of BOTOX (n=223), or placebo (n=241).
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.
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.
The recommended dose is 50 Units per axilla. The hyperhidrotic area to be injected should be defined using standard staining techniques, e.g., Minor's Iodine-Starch Test. The recommended dilution is 100 Units/4 mL with 0.9% preservative -free sterile saline (see Table 1). Using a sterile 30 gauge needle, 50 Units of BOTOX (2 mL) is injected intradermally in 0.1 to 0.2 mL aliquots to each axilla evenly distributed in multiple sites (10-15) approximately 1-2 cm apart.
Sunburn alert: The AHA/BHA Exfoliating Cleanser and AHA/BHA Cream in the Lytera® 2.0 Advanced Pigment Correcting System contain an alpha-hydroxy acid (AHA) that may increase the skin’s sensitivity to the sun and particularly the possibility of sunburn. Patients should use a sunscreen, wear protective clothing, and limit sun exposure while using these products (or this system) and for a week following.
In rare cases, Botox toxin can spread to areas beyond the injection site. If this happens, you may experience muscle weakness, vision changes, difficulty swallowing, and drooping eyelids. To reduce your risk of serious side effects and complications, always make sure Botox is prescribed and administered by a trained healthcare professional who has experience in using Botox.
Over the next three decades, 1895-1925, as food canning was approaching a billion-dollar-a-year industry, botulism was becoming a public health hazard. Karl Friedrich Meyer, a prodigiously productive Swiss-American veterinary scientist created a center at the Hooper Foundation in San Francisco, where he developed techniques for growing the organism and extracting the toxin, and conversely, for preventing organism growth and toxin production, and inactivating the toxin by heating. The California canning industry was thereby preserved.
It's safe to say that the mouth is the clearest giveaway of work done too early. Youthful lips tend to have substantial volume and turn up naturally at the corners, meaning the best strategy for flattering them often comes down to a good signature lip color. For women who remain self conscious about the size or symmetry of their lips—think a slightly lopsided appearance, for instance—Botox can be injected into the orbicularis oris muscle along the lip line as an alternative to lip fillers. "When certain individuals smile, the lip flips in and they lose that upper volume," says Dara Liotta, a New York City-based plastic and cosmetic surgeon. "This relaxes the outer layers of the circular muscle around the lips and looks much more natural than filler." Additionally, injections along the jawline—or more specifically, the masseter muscle—have risen in popularity to relieve stress-induced jaw clenching and have also been known to refine the area. "A lot of people hold tension in the jaw area and when you relax that muscle, the chin comes out of the shadow of your lower lip,” explains Liotta. But the best advice of all? Forget about those self-perceived imperfections and smile. You're only in your '20s once.
In clinical trials, 30.6% of patients (33/108) who were not using clean intermittent catheterization (CIC) prior to injection, required catheterization for urinary retention following treatment with BOTOX® 200 Units as compared to 6.7% of patients (7/104) treated with placebo. The median duration of post-injection catheterization for these patients treated with BOTOX® 200 Units (n = 33) was 289 days (minimum 1 day to maximum 530 days) as compared to a median duration of 358 days (minimum 2 days to maximum 379 days) for patients receiving placebo (n = 7).
