Drug X is a weakly acidic drug that has a pKa of 7.2 a) Calculate the percentage of the ionized form of this drug in the duodenum which has a pH of 5.0? explain the concept and the scientific rationale behind your answer. b)if the pH in the stomach is 2 and that in the intestine is 8, in a new line write which of these two GIT parts drug X is maximally absorbed from; the stomach or the intestine?...
I need to know the % output when : weak acid( pKa=6) is in pH of urine at 6 and pH or urine at 8. Also the weak base (pKa 7) in pH of urine at 6 and pH or urine at 8. Effect of urine pH on delivery route: Weak organic acids and bases can reach the luminal fluid (the filtrate, the primary urine) either by glomerular filtration in Bowman's capsule or by secretion in the proximal tubule. In...
1. Part A.Acetaminophen is a weak organic acid with a pKa of 9.5. What percentage of a given dose will be in the lipid soluble form at an intestinal pH of 7.5%? Part B.Psueduoephedrine is a weak organic base with a pKa of 9.8. What will be the ratio of non-lipid soluble drug to lipid soluble drug at a stomach pH of 2.8? As the dose of psudoephedrine which you have just take moves from your stomach with a pH...
