GP14 [Apr01] [Jul04] (A Basic drug with a pKa of 8.7)A. ?B. ?C. Will be predominantly ionised at plasma pH CommentsA basic drug will be predominantly ionised at a pH below its pKa For a drug with a pKa of 8.7 undegoing the reaction: B + H+ <-> BH+:

• At pH = pKa we can calculate the following: pH = pKa + log([B]/[BH+]) (Henderson-Hasselbalch equation) If pH = pKa then this simplifies to pKa = pKa + log([B]/[BH+]) log([B]/[BH+]) = 0

Thus, taking anti-logs (easy as log 1 = 0): ([B]/[BH+]) = 1 so [B] = [BH+] -> 50% ionised & 50% unionised

By doing similar calculations using the Henderson-Hasselbalch equation, the ratio B/BH+ can be determined at any pH value. For example:

• For pH = pKa + 1 -> 10% ionised & 90% unionised (approx)

• For pH = pKa -> 50% ionised & 50% unionised

• For pH = pKa - 1 -> 90% ionised & 10% unionised

• For pH = pKa - 2 -> 99% ionised & 1% unionised

LA12 [Jul98] The site of action of benzocaine is: A. Same site as saxitoxin (alt option: At the channel mouth )B. Inside Na+ channel C. At axoplasmic end of Na+ channel D. At Ca++ channel E. In the cell membrane CommentsOption "E In the cell membrane" would be the best answer. Benzocaine is an ester local anaesthetic which is a secondary amine. It is unique among clinically useful LA's. As a weak base with a low pKa (3.5) - therefore at physiological pH exists primarily in an unionized form rendering it lipid soluble (& water-insoluble). Because of this it is suitable for topical anaesthesia of mucus membranes (in concentrations up to 20%). Its systemic toxicity is also diminished because of rapid hydrolysis. It has a very rapid onset Mechanism of action"Certain local anaesthetics (eg benzocaine) are only present in the body as

uncharged, tertiary bases, and must therefore act in a different way. Theyare believed to cause conduction blockade by "membrane expansion" (ie bycausing swelling of the lipoprotein matrix of the Na+ channel. To some extent,other local anaesthetics, which are partly present in the neurilemma as theuncharged base may act in this manner."

- from Calvey & Williams "Principles and Practice of Pharmacology for Anaesthetists" 4th ed 2001, p152-3So option "E In the cell membrane" would be the best answer. Benzocaine is a weak base Potential problems with benzocaine1. Allergic reactions Metabolism to produce para-amino benzoic acid (PABA) so potential for allergic reactions (like other ester LAs) 2. Methaemoglobinaemia Benzocaine can cause methaemoglobinaemia [1] (http://www.jaoa.org/cgi/content/full/105/8/381)(so dose is limited to 200-300mg in adults). Babies are at higher risk [2] (http://www.tiaft.org/tiaft98/thu/p/t_p_29.html) because of their smaller weight (easier to give a high dose) and because of lower levels of the enzymes which convert met-HbF back to Hb. Treatment of symptomatic methaemoglobinaemia is IV 1% methylene blue at a dose of 1-2mg/kg over 20 minutes. Note that with concentrations of 20%, one ml will contain 200mg! Regarding methaemoglobinaemia"Of 198 reported adverse events of all types reported with benzocaine, 132 cases (66.7%)involved definite or probable methemoglobinemia, including 107 serious adverse events (81.1%) and two deaths (1.5%). The formulation implicated was a spray in 123 cases(93.2%), a benzocaine-containing lozenge in two cases (1.5%), and a gel in one case. Ofthe 69 cases that specified a dose, 37 (53.6%) indicated that a single spray was applied,which is approximately the recommended amount.

"Health professionals involved in endoscopy, intubation, bronchoscopy, or similar invasive

Page 52: Mc qs in pharmacology

procedures using benzocaine-containing sprays should know that (1) administration may causeMHb with potentially serious consequences, (2) identifying the reaction to benzocaineusually requires cooximetry (although it can be implied by symptoms), and (3) treatmentinvolves immediate intravenous administration of 1 to 2 mg/kg of methylene blue."
