Dextrose therapeutic solutions

Polysorbate 80 is a surfactant commonly used in protein parenteral formulations to minimize denaturation at the air-water interface. Polysorbate 80 is also sometimes used in injectable solution formulations of small molecules for the purpose of solubility enhancement owing to micelle formation. Docetaxel, a first-line therapeutic to treat breast and small cell lung cancer, is practically insoluble in water and is solubilized in Taxotere to 40mg/ml in 100% polysorbate 80, and is diluted four-fold with the supplied diluent of 13% ethanol in water, then further diluted to 0.3-0.74mg/ml with saline or dextrose 5% prior to administration by rV infusion. The dose of Taxotere is up to 5 ml of polysorbate 80 per dose, representing the estimated maximum amount administered intravenously. 

Maltodextrin may also be used in pharmaceutical formulations to increase the viscosity of solutions and to prevent the crystallization of syrups. Therapeutically, maltodextrin is often used as a carbohydrate source in oral nutritional supplements because solutions with a lower osmolarity than isocaloric dextrose solutions can be prepared. At body osmolarity, maltodextrin solutions provide a higher caloric density than sugars. 

Sodium sulfadiazine and sulfafurazole diolamine in therapeutic doses (1 mg) added to 5% dextrose and 5% dextrose and saline solution have been found to be compatible, yet when added to commercial polyionic solutions (such as Abbott lonosol B, Baxter electrolyte No.2) both rapidly form heavy precipitates. pH and temperature are two vital parameters, but the pH effect is not simply a solubility-related phenomenon. Polyionic solutions of a lower initial pH (4.4-4.6) cause crystallisation of sulfafurazole at room temperature within 2.5 h, the pH values of the admixtures being 5.65 and 5.75 respectively. Other solutions with slightly higher initial pH levels (6.1-6.6) formed crystals only after preliminary cooling to 20°C at pH values from 4.25 to 4.90. If the temperature remains constant, the intensity of precipitation varies with the composition and initial pH of the solution used as a vehicle.
