QUESTION 2A The figure belоw illustrаtes the plаsmа cоncentratiоn vs time profile for memantine following two treatments: acidic urine (pH of 5.1, black circle), alkaline urine (pH of 8.1, red circle) after a single oral dose. Memantine has a pKa of 10.3 and in normal urine pH the fraction of the dose excreted unchanged in the urine is 0.9. At a urine pH of 8.1 the fraction of the dose excreted unchanged in the urine is reduced to 0.5. [From: Freudenthaler S, Meineke I, Schreeb KH et al. Influence of urine pH and urinary flow on the renal excretion of memantine. Br J Clin Pharmacol 1998;46:541–546.] Answer the following questions: 1. Is memantine a weak acid or a weak base? Provide a rationale. 2. Provide an explanation for the observed plots seen at the different pH values. Keep your answer very brief and utilize equations in your explanations as much as possible to justify your answers.
