Gentamicin sulfate is a water soluble antibiotic of the aminoglycoside group. Gentamicin Sulfate Ophthalmic Solution is a sterile, aqueous solution buffered with dibasic sodium phosphate and monobasic sodium phosphate to approximately pH 7 (pH range 6.5 - 7.5) for ophthalmic use. Each mL contains gentamicin sulfate, USP (equivalent to 3 mg gentamicin base), sodium chloride; and benzalkonium chloride (0.1 mg) as a preservative. Gentamicin is obtained from cultures of Micromonospora purpurea. It is a mixture of the sulfate salts of gentamicin C1, C2, and C1A. All three components appear to have similar antimicrobial activities. Gentamicin Sulfate occurs as a white powder and is soluble in water and insoluble in alcohol.
Gentamicin Sulfate Ophthalmic Solution is indicated in the topical treatment of ocular bacterial infections, including conjunctivitis, keratitis, keratoconjunctivitis, corneal ulcers, blepharitis, blepharoconjunctivitis, acute meibomianitis, and dacryocystitis caused by susceptible strains of the following microorganisms:
Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, Streptococcus pneumoniae, Enterobacter aerogenes, Escherichia coli, Haemophilus influenzae, Klebsiella pneumoniae, Neisseria gonorrhoeae, Pseudomonas aeruginosa, and Serratia marcescens.
Published Studies Related to Gentamicin (Gentamicin Ophthalmic)
Intratympanic Treatment of Intractable Unilateral Meniere Disease: Gentamicin or Dexamethasone? A Randomized Controlled Trial. [2011.11.18]
Objective. To determine the efficacy and safety of low-dose intratympanic gentamicin (ITG) compared with intratympanic dexamethasone (ITD) in patients with intractable unilateral Meniere disease (MD).Study Design.ITD offers poorer vertigo control rate, and hearing preservation is achieved only in cases with no vertigo recurrences.
Effects of intracameral triamcinolone and gentamicin injections following cataract surgery. [2011.07]
CONCLUSION: Intracameral injections of triamcinolone acetonide and gentamicin appear to be a promising treatment option for the control of post-operative inflammation following cataract surgery.
A randomized controlled trial of nebulized gentamicin in non-cystic fibrosis bronchiectasis. [2011.02.15]
RATIONALE: Bronchiectasis is a chronic debilitating disease with few evidence-based long-term treatments. OBJECTIVES: A randomized controlled trial assessing the efficacy of nebulized gentamicin therapy over 1 year in patients with non-cystic fibrosis bronchiectasis...
Local administration of antibiotics by gentamicin-collagen sponge does not improve wound healing or reduce recurrence rate after pilonidal excision with primary suture: a prospective randomized controlled trial. [2010.12]
BACKGROUND: Excision and primary suture for pilonidal disease is associated with a high rate of wound infection and recurrences. This randomized, controlled study was designed to analyze the effect of local application of a gentamicin-containing collagen sponge (Collatamp((R))) in reducing the wound infection rate and recurrences after excision of pilonidal sinus and wound closure with primary midline suture... CONCLUSIONS: This randomized, controlled study showed no significant differences in the rates of wound infection, wound healing, and recurrences when a gentamicin-collagen sponge was added to the surgical treatment of pilonidal disease with excision and primary midline suture. This does not support the use of gentamicin-collagen sponge for the surgical treatment of pilonidal disease.
Gentamicin-collagen sponge for infection prophylaxis in colorectal surgery. [2010.09.09]
BACKGROUND: Despite the routine use of prophylactic systemic antibiotics, surgical-site infection continues to be associated with significant morbidity and cost after colorectal surgery. The gentamicin-collagen sponge, an implantable topical antibiotic agent, is approved for surgical implantation in 54 countries. Since 1985, more than 1 million patients have been treated with the sponges... CONCLUSIONS: Our large, multicenter trial shows that the gentamicin-collagen sponge is not effective at preventing surgical-site infection in patients who undergo colorectal surgery; paradoxically, it appears to result in significantly more surgical-site infections.

Clinical Trials Related to Gentamicin (Gentamicin Ophthalmic)
Gentamicin Treatment Prior to Schwannoma Surgery - Residual Function [Recruiting]
The purpose of the study is to determine whether vestibular and postural compensation
following schwannoma surgery is improved by ablating remaining vestibular function prior to
surgery, through gentamicin injections in the middle ear.
Local Gentamicin Application to Reduce Postoperative Infection Rate [Completed]
The majority of elderly patients with a displaced fracture of the proximal femur are now
treated with a hemiarthroplasty. Prosthetic joint infection is a devastating complication,
and the infection rate is high in this group of elderly patients. Local application of
gentamicin produces high antibiotic concentrations in the wound. The aim of this study is to
determine whether locally administered collagen-gentamicin in the joint perioperatively in
addition to routine IV prophylaxis with beta-lactam antibiotics can reduce the early
postoperative infection rate (< 4 weeks postoperative)after hemiarthroplasty in proximal
Pharmacokinetic (PK) and Pharmacodynamic (PD) Modeling of Ampicillin and Gentamicin in Peripartum Patients [Not yet recruiting]
This study proposes to compare the metabolism of Ampicillin and Gentamicin by pregnant women
to that of non-pregnant women; the placental transfer over time; and the subsequent
metabolism of the transferred drug(s) in the neonate.
Gentamicin Bladder Instillation Trial [Recruiting]
Recurrent UTIs are common among patients on IC. These create significant patient morbidity
and healthcare burden. In desperation, many physicians prescribe prophylactic oral or
intravesical antibiotics. This practice is common among our Gillette clinic patients.
However, the benefit is unclear and the risks are not insignificant. As such, practice
variation is significant. In order to better define the evidence for or against gentamicin
bladder irrigation and thus inform clinical practice both locally at our Gillette urology
clinic and for practitioners at large we will pursue the following specific aims:
1. Compare rates of symptomatic urinary tract infection and asymptomatic bacteriuria among
a population of Gillette patients on IC with and without gentamicin bladder
2. Compare antibiotic resistance rates among a population of Gillette patients on IC with
and without gentamicin bladder instillation.
Topical Gentamicin Cream Versus Alternating Gentamicin and Mupirocin Cream in Peritoneal Dialysis [Not yet recruiting]
Catheter-related infection, namely exit site infection and peritonitis, is the commonest
complication of peritoneal dialysis. This complication causes significant morbidity and
mortality in patients requiring peritoneal dialysis. Topical application of mupirocin 2%
cream was first proven to be effective in reduction of staphylococcus-related catheter
infection in 1990s. Subsequent randomized trial published in 2005 showed that gentamicin
cream was superior to mupirocin 2% cream in reducing both Gram's positive and Gram's
negative related catheter infection. However, a retrospective report published in 2007 puts
the use of prophylactic antibiotic cream into a question. It reported an emergency of
non-tuberculous mycobacterial infection in a dialysis center in Hong Kong after practising
prophylactic application of gentamicin cream at the catheter exit site. The following
prospective, randomized and open-label study aims to find out an optimal regimen of topical
antibiotic prophylaxis in patients requiring peritoneal dialysis.
