Phenytoin is an extremely weak acid, pKa 8.3, with very poor water solubility. Solubility of the sodium salt in water is 15 g/L, and in ethanol it is 95 g/L. It is freely soluble in warm propylene glycol and it has a molecular weight of 274.3. We are going to prepare five 5 mL vials of this product. With its poor water solubility, how would you propose that the required concentration of 50 mg/mL be achieved and which and how...
