Sample text

The physician may write a prescription for hydrocortisone cream 1% as 1 : 100. This ratio strength of 1 : 100 means that there should be 1 g of hydrocortisone in 100 g of cream. A solution labeled as 1 : 50 for sucrose means that there are 1 g of sucrose in every 50 mL of the preparation. Thus, the definition of ratio strength is the number of grams or milliliters of the solute to the number of grams or milliliters of the preparation. 20. Find the ratio strength of a solution containing 300 mL of propylene glycol in 1 L of the preparation.

It should be noted, however, that each heat of solution varies depending on the solvent being used. For exothermic reactions, the more negative the heat of solution, the higher is the solubility of the active pharmaceutical ingredient (API) form in the solvent. Unlike DSC, SC does not require the sample to be heated through the phase transition, which may result in degradation of the API. Another method that is widely acceptable for polymorphic measurement is x-ray diffraction. This method is useful for initial determination of different morphology patterns; however, these differences may be due to variations in orientation rather than being related directly to crystal structure (Lindenbaum and McGraw, 1985).

2 mL of water at 25◦ C. 78 g of calcium chloride should dissolve easily in 1 L of the aqueous solution. By definition, the solubility of any substance is the concentration of the substance in a saturated solution at a given temperature and pressure. Unless otherwise stated, the pressure is assumed to be 1 atmosphere. 7 mL an endothermic process; the solubility increases with increasing temperature of the solution). It is always a good idea to check the solubility of compounds in the vehicle to be used for the preparation prior to compounding.
