Botox (Botulinum Toxin Type A) - Summary



BOTOX® (Botulinum Toxin Type A) Purified Neurotoxin Complex is a sterile, vacuum-dried purified botulinum toxin type A, produced from fermentation of Hall strain Clostridium botulinum type A grown in a medium containing casein hydrolysate, glucose and yeast extract. It is purified from the culture solution by dialysis and a series of acid precipitations to a complex consisting of the neurotoxin, and several accessory proteins. The complex is dissolved in sterile sodium chloride solution containing Albumin (Human) and is sterile filtered (0.2 microns) prior to filling and vacuum-drying.

BOTOX® is indicated for the treatment of cervical dystonia in adults to decrease the severity of abnormal head position and neck pain associated with cervical dystonia.

BOTOX® is indicated for the treatment of severe primary axillary hyperhidrosis that is inadequately managed with topical agents.

BOTOX® is indicated for the treatment of strabismus and blepharospasm associated with dystonia, including benign essential blepharospasm or VII nerve disorders in patients 12 years of age and above.

The efficacy of BOTOX® treatment in deviations over 50 prism diopters, in restrictive strabismus, in Duane's syndrome with lateral rectus weakness, and in secondary strabismus caused by prior surgical over-recession of the antagonist has not been established. BOTOX® is ineffective in chronic paralytic strabismus except when used in conjunction with surgical repair to reduce antagonist contracture.

Published Studies Related to Botox (Botulinum Toxin Type A)

The early use of botulinum toxin in post-stroke spasticity: study protocol for a randomised controlled trial. [2014]
BACKGROUND: Patients surviving stroke but who have significant impairment of function in the affected arm are at more risk of developing pain, stiffness and contractures. The abnormal muscle activity, associated with post-stroke spasticity, is thought to be causally associated with the development of these complications...

Correlation of botulinum toxin dose with neurophysiological parameters of efficacy and safety in the glabellar muscles: a double-blind, placebo-controlled, randomized study. [2014]
Despite the extensive use of botulinum toxin type A (BoNT-A) in treatments for glabellar frown lines, the dose-response effect in the glabellar muscles remains unknown. The aim of this randomized, double-blind, placebo-controlled prospective study was to characterize the neurophysiological parameters that correlate with the effect of BoNT-A in the glabellar muscles and its diffusion to surrounding ocular muscles...

OnabotulinumtoxinA for treatment of chronic migraine: PREEMPT 24-week pooled subgroup analysis of patients who had acute headache medication overuse at baseline. [2013]
Acute headache medication overuse (MO) is common in patients with chronic migraine (CM). We evaluated safety and efficacy of onabotulinumtoxinA as preventive treatment of headache in CM patients with baseline MO (CM+MO) in a planned secondary analysis from two similarly designed, randomized, placebo-controlled, parallel, Phase III trials.

Clinical Trials Related to Botox (Botulinum Toxin Type A)

Comparison of Korean Botulinum Toxin Type A Versus Botox in the Treatment of Essential Blepharospasm [Completed]
To compare the efficacy and safety of Korean botulinum toxin A (KbtxA, Pacific Pharmaceuticals, Korea) against Botox in the treatment of essential blepharospasm, we performed a double-blinded, randomized, comparative trial comparing KbtxA and Botox for treatment of blepharospasm in 60 patients of the intention to treat population and 52 patients (26 patients from each group) of the per protocol population. The improvement of severity of spasm (SS) at 4 weeks post-injection as a primary efficacy outcome, qualifying non inferiority to the control group, Changes in eyelid closure force (CF) and functional visual status (FVS) after injection for secondary efficacy outcomes, and adverse effects for safety evaluation. Improvement of SS was noted in 90. 3% of the KbtxA group and 86. 2% of the Botox group. There were no significant differences between treatment groups in the changes of CF and FVS after injection (p>0. 05). Adverse effects developed in 16. 1% of the KbtxA group and 27. 6% of the Botox group, but no serious adverse events were found in either group. KbtxA was not inferior to Botox in treatment efficacy and was clinically safe with no serious adverse effects when used to treat essential blepharospasm.

Comparative Study of the Effect of Dysport and Botox [Completed]
The purpose of this study is to test the effect of Dysport and Botox on forehead wrinkles and EMG activity.

Over Active Bladder Instillation Study - Botox [Recruiting]
The purpose of this study is to determine whether women with overactive bladder (OAB) who receive direct instillation via a catheter of a Botulinum-A Toxin (Botox) with Dimethyl Sulfoxide (DMSO) solution experience significantly better improvement of their OAB symptoms when compared to a similar group of women with OAB who receive instillation of DMSO only.

Study to Determine If the Volume Used to Dilute BOTOX Cosmeticâ„¢ for Injection Affects Its Overall Effect and Duration. [Completed]
It is thought that the amount of fluid used to dilute Botox for injection has an effect on the quality of the result and the duration of effect on the treatment of upper face rhytides, even though the dose remains the same.

The study was designed to test this thinking, using the crow's feet wrinkles as the treatment area.

Botulinum Toxin Type A (Dysport) Associated With Rehabilitation Treatment in Patients With Primary Myofascial Pain Syndrome [Completed]
The main purpose of this study is to determine the effectiveness and safety of one dose of botulinum toxin type A (Dysport) associated with rehabilitation treatment on pain control in patients with a type of back pain called primary myofascial pain syndrome.

Botox review by 51 year old female patient

Overall rating:  
Effectiveness:   Highly Effective
Side effects:   Mild Side Effects
Treatment Info
Condition / reason:   migraines
Dosage & duration:   1 vial (dosage frequency: every 3-6 months) for the period of five plus years
Other conditions:   none
Other drugs taken:   none
Reported Results
Benefits:   I used to have near-daily migraines. I tried every migraine medication on the market. Either they didn't have any effect, or I was unable to tolerate them due to side-effects. With Botox injections administered by a very knowledgable neurologist who is also a pain specialist, I am virtually migraine-free for months.
Side effects:   Sometimes I had some minor swelling at an injection site. It went away within days.
Comments:   My neurologist injects the tiny cranial muscles as well as muscles along my neck and upper shoulder. He uses a tiny needle and injects very little at each site. He determines where the trigger points are before administering the Botox. PLEASE NOTE: If using Botox for migraines, do go to a neurologist who is experienced with migraine pain. DO NOT have this done by a cosmetic surgeon!
