Bacitracin Zinc and Polymyxin B (Bacitracin / Polymyxin B Sulfate Ophthalmic) - Summary




Bacitracin Zinc and Polymyxin B Sulfate Ophthalmic Ointment, USP, is a sterile antimicrobial ointment for ophthalmic use. Each gram contains: bacitracin zinc equivalent to 500 bacitracin units, polymyxin B sulfate equivalent to 10,000 polymyxin B units, mineral oil, and white petrolatum. Bacitracin zinc is the zinc salt of bacitracin, a mixture of related cyclic polypeptides (mainly bacitracin A) produced by the growth of an organism of the licheniformis group of Bacillus subtilis var Tracy. It has a potency of not less than 40 bacitracin units per mg.

Bacitracin Zinc and Polymyxin B Sulfate Ophthalmic Ointment is indicated for the topical treatment of superficial infections of the external eye and its adnexa caused by susceptible bacteria. Such infections encompass conjunctivitis, keratitis and keratoconjunctivitis, blepharitis and blepharoconjunctivitis.

Published Studies Related to Bacitracin Zinc and Polymyxin B (Bacitracin / Polymyxin B Ophthalmic)

Detection of IgE antibodies to bacitracin using a commercially available streptavidin-linked solid phase in a patient with anaphylaxis to triple antibiotic ointment. [2007.06]
BACKGROUND: Bacitracin is a commonly used topical antibiotic that has on occasion been reported to cause anaphylaxis. Evidence of the role of bacitracin specific IgE in such reactions has been demonstrated by skin testing. Because of the potential for provoking a systemic reaction by skin testing, it would be advantageous to develop an in vitro test for bacitracin specific IgE. OBJECTIVE: To report our experience coupling bacitracin to a solid phase and using it to detect specific IgE to bacitracin by fluorescent enzyme immunoassay... CONCLUSIONS: We demonstrate the presence of IgE antibodies to bacitracin in a patient with anaphylaxis to triple antibiotic ointment using a recently described procedure for producing custom allergen solid phases for immunoassay.

Clinical Trials Related to Bacitracin Zinc and Polymyxin B (Bacitracin / Polymyxin B Ophthalmic)

Clinical Evaluation of Bacitracin [Completed]

The Relationship of Hemoglobin A1c and Diabetic Wound Healing [Not yet recruiting]
The purpose of this study is to investigate the relationship of hemoglobin A1c in diabetic wound healing. Additionally, a comparison of two wound dressings, AmeriGel® (Amerx Health Care Corp., Clearwater, FL) and Bacitracin, with and without vitamin C supplementation, will be done to evaluate impact on time to wound closure.

Effectiveness of Antibiotic Delivery Via Bio-absorbable Sponge [Recruiting]
This study will evaluate the efficacy of a nasopore sponge dressing soaked in Bacitracin VS a sponge soaked in Saline / and the administration of oral antibiotics.

Polymem vs. Bacitracin/Xeroform in Treating Burn Wounds [Recruiting]
Patients will be screened at the initial visit to the burn center. If the patients are eligible according to the inclusion/exclusion criteria, consent for the study will be obtained. One of the investigators will identify two sites that appear to be the same depth on each patient [1 site Polymen and 1 site bacitracin/xeroform )]. The depth of injury will be verified as partial thickness using laser doppler. Each site will be at least 4cm x 4cm in size. One site will be identified for bacitracin/xeroform and one site for Polymen. All burns will be initially debrided and cleaned according to burn unit protocol. The dressing will then be applied. All dressings will be covered with cotton gauze and ace wraps. Laser Doppler will be utilized to determine burn depth at both the trial and control sites. On each subsequent visit, patients will rate the pain of the dressing change on a 1-10 pain intensity scale. It will be noted if the wound appears infected or if antibiotics are prescribed.

The study will end for each patient when the investigator determines that 95% of their burn has re-epithelized.

Nasospore Stent For Use in Enodscopic Sinus Surgery [Recruiting]
The purpose of this study is to evaluate a stenting material called Nasopore. This is a synthetic material approved by FDA for use as a stent in postoperative sinus surgery patients. This study will compare the Nasopore stent to other approved stenting materials.
