Botox is mostly performed in a medical setting and is known to be a quick and painless medical procedure.The skin is cleansed with alcohol or another antiseptic and a topical anesthetic ointment is applied to the skin. After ten minutes the physician or nurse injects Botox or disport with a very fine needle. The procedure should be almost painless and takes only takes about 15 minutes to perform. You can easily walk out of the office and resume your daily activities.The effect of Botox or Dysport will usually take 48 to72 hours before you see the results.
In May, hedge fund Appaloosa Management, run by David Tepper, received antitrust clearance from the Federal Trade Commission to potentially increase its stake in the Botox-maker. This means that Appaloosa now has more flexibility to push for further changes at Allergan. It remains to be seen if that happens, but if so, it could mean more changes are ahead for the drugmaker.
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).
There are many physicians who encourage their patients to either work the area several times during the next several days or, alternatively, to not use the affected muscles during the next several days. Many practitioners do not tell the patients to do anything in particular other than to avoid strenuous activity for several hours afterward because of an increased risk of bruising.
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.
Significant improvements compared to placebo in the primary efficacy variable of change from baseline in daily frequency of incontinence episodes were observed for BOTOX® (100 Units) at the primary efficacy time point at week 6. Increases in maximum cystometric capacity and reductions in maximum detrusor pressure during the first involuntary detrusor contraction were also observed. These primary and secondary endpoints are shown in Table 23.
Each vial of BOTOX contains either 50 Units of Clostridium botulinum type A neurotoxin complex, 0.25 mg of Albumin Human, and 0.45 mg of sodium chloride; 100 Units of Clostridium botulinum type A neurotoxin complex, 0.5 mg of Albumin Human, and 0.9 mg of sodium chloride; or 200 Units of Clostridium botulinum type A neurotoxin complex, 1 mg of Albumin Human, and 1.8 mg of sodium chloride in a sterile, vacuum-dried form without a preservative.
The needle should be inserted approximately 2 mm into the detrusor, and 30 injections of 1 mL (~6.7 Units) each (total volume of 30 mL) should be spaced approximately 1 cm apart (see Figure 1). For the final injection, approximately 1 mL of sterile normal s aline should be injected so that the remaining BOTOX in the needle is delivered to the bladder. After the injections are given, the saline used for bladder wall visualization should be drained. The patient should be observed for at least 30 minutes post -injection.
The patient is placed in a somewhat raised position on the exam table, and the areas to be injected are cleansed with a nonalcohol cleanser, such as Hibiclens or Betadine. Some physicians will apply a topical anesthetic, such as EMLA cream or some alternative, at this time. The Botox is then injected into the desired areas. Typical injection patterns include about four or five areas on each side of the forehead and two or three areas on either eye area. More areas can be injected by skilled physicians, depending on the type of wrinkles and the desired effect for the patient. It is common for pressure to be applied if an area seems to be bleeding after the injection. While ice is sometimes applied beforehand for comfort reasons, direct pressure is much more effective than ice for control of bleeding and bruising.
Botox should only be injected with sterile instruments in a doctor's office or a medical spa — not at Botox parties at your local nail salon or neighbor's living room. Botox injection is usually performed with some local anesthesia or a numbing cream. You may feel some minimal discomfort from the shot, but today's needles are so thin and fine that the procedure is often painless. Depending on the extent of treatment, the procedure can take anywhere from a few minutes to 20 minutes.
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.
