In cell biology, ion trapping is the build-up of a higher concentration of a chemical across a cell membrane due to the pKa value of the chemical and difference of pH across the cell membrane. This results in basic chemicals accumulating in acidic bodily fluids such as the cytosol, and acidic chemicals … See more Many cells have other mechanisms to pump a molecule inside or outside the cell against the concentration gradient, but these processes are active ones, meaning that they require enzymes and consume cellular See more Ion trapping is the reason why basic (alkaline) drugs are secreted into the stomach (for example morphine), where pH is acidic, and acidic drugs are excreted in urine where the … See more • Osmosis • Biophysics • Forced diuresis • Henderson-Hasselbalch equation See more

WebDec 2, 2016 · In the absence of other equilibria than those considered previously, this diagram would help to known the concentration of ammonia from the pH initial of the sample to be titrated, that is, a pH of about 7 for a 2% boric acid trapping solutions corresponds to a p[NH 3] of about 2. However, in numerous cases, things are not an easy … WebDepending on the urine pH, a weak acid or base can be more or less ionised in the urine and therefore for more or less reabsorbed (urine ion trapping). Active reabsorption occurs mainly for endogenous products such as vitamins, glucose and amino acids and similar substances. Clinical implications cub scout pack 90
What is ion trapping in pharmacology give an example?
WebMay 12, 2010 · pH differences can also cause trapping or altered absorption in the stomach & small intestine. Drug Interactions: Drugs that alkalinize ... only ~1% of the dose appears in the urine. In contrast, when the urine is acidified to 4.9-5.3 pH by repetitive ingestion of ammonium chloride, ~70% of the dose is recovered in the urine. (From Beckett ... WebWhen pH of a solution is equal to pKa of dissolved drug, then 50% of the drug is ionized, another 50% is unionized. Ion trapping is the reason why basic (alkaline) drugs are … WebOct 10, 2011 · For example, The non ionised form of weakly acidic drug (eg Aspirin ; pKa 3.5) which crosses the gastric mucosa (pH 2) reverts to ionised form within the cell (pH 7) and hence slowly passes to the extracellular fluid. This type of ion trapping possibly contributes to gastric mucosal cell damage caused by Aspirin. easter 2026 date
