How long is gentamicin stable?

After dilution: when diluted with 0.9% sodium chloride or 5% glucose solution, gentamicin is stable for 24 h at 25°C. Chemical and physical in-use stability has been demonstrated for 24 hours at 25°C.

How should gentamicin be stored?

Sterile solutions of gentamicin sulfate should be stored at 2-8 °C. Solutions of gentamicin have been shown to be stable when stored at room temperature, and in boiling aqueous buffers of pH 2-14. 2 A solution at 1 mg/ml in 0.1 M potassium phosphate buffer (pH 8.0), stored at 2-8 °C, should be used within 30 days.

Can gentamicin be frozen?

The results of the study indicated that minibag admixtures of carbenicillin disodium, cephalothin sodium, cloxacillin sodium, gentamicin sulfate, penicillin G potassium, erythromycin gluceptate, cefazolin sodium and rolitetracycline base in the concentrations tested can be frozen for 30 days without a significant loss …

What happens if you freeze liquid antibiotics?

Although many antibiotics are chemically stable when stored as frozen aqueous solutions,^ some antibiotics (including ampicillin) degrade substantially in aqueous solution below 0 °C. Lynn^ found that a concentrated solution of ampicillin in water (approximately 330 mg/mL) lost 10% potency in 20 hours at -20 °C.

How long is gentamicin sulfate good for?

Gentamicin 0.3% (ophthalmic solution): Instill 1 or 2 drops into affected eye(s) every 4 hours. For severe infections, up to 2 drops may be instilled every hour.

Several antibiotics are Food and Drug Administration–approved for IV push administration, including many beta-lactams. In addition, cefepime, ceftriaxone, ertapenem, gentamicin, and tobramycin have primary literature data to support IV push administration.

What happens if medication gets too cold?

How does the temperature affect medications? When medication is stored at an extremely hot or cold temperature, it can become compromised or degrade more quickly. Each medication is different. The impact of temperatures outside of the range recommended by the manufacturer varies by each drug and dosage form.

Does gentamicin sulfate burn?
