Further, as questions developed concerning reduced concentration of preservatives and the microbiological safety of these processed meats, additional advances have resulted in a wide variety of ingredients and processes designed to provide supplementary antimicrobial effects for improved product safety.
Activated charcoal (130 mls of ToxiBan® Lloyd, Inc, Shenandoah, IA 51601, USA) containing 104 mg of activated charcoal/ml and 62.5 mg kaolin/ml, with an unspecified concentration of preservatives, suspending agents and water was administered orally.
The typical concentrations of preservatives in consumer products were obtained by researching the Internet and by direct inquiries to manufacturing companies.
Its growth in orange juice is inhibited by high concentrations of preservatives, potassium sorbate (500 mg/L) and natrium benzoate (1000 mg/L).
A novel approach for determination of low concentrations of the preservative, benzalkonium chloride (BCCl), in pharmaceutical formulation constitutes is presented.
However, it is interesting to note that most of the commercial fluoroquinolone ophthalmic solutions contain very low concentrations of the preservatives benzalkonium chloride or edetate disodium (Ciloxan at 0.006%, Ocuflox at 0.05 mg and Quixin at 0.005%) in their formulations.
The MTT test revealed that the cytotoxicity of antiglaucoma eye-drops was primarily related to the concentration of their common BAC preservative (0.02% BAC-latanoprost>0.015 BAC-latanoprost>0.015% BAC-travoprost>0.005 BAC-travoprost>0.005
Thimerosal was added at the formulation step to reach a concentration of 100 μg/mL as a preservative to those batches to be filled into multidose vials.
Vaccine samples were removed under Biosafety Level-2 conditions and tested both undiluted and at a 10-fold dilution to reduce the concentrations of stabilizer and preservative.
Erbitux Merck (Darmstadt, Germany) (cetuximab) was supplied in single-use, 50 ml vials containing 100 mg of cetuximab at a concentration of 2 mg ml−1 in a preservative free solution.
The drug concentration, pH, and addition of preservatives and/or polymers in Voriconazole in situ gelling formulations did not show any corneal damage as the corneal hydration value for all corneas remained in the normal range of 75%to80%0% (Table 3).
