Sample text

When a drug is given as a continuous infusion it will increase in concentration in the blood until the rate of elimination is equal to the infusion rate. At this point the amount going in per unit time is equal to the amount going out. The plasma concentration at this point is called the concentration at steady state, or Css (Figure 4–5). Plasma concentration 20 Steady-state concentration (Css ) Time FIGURE 45 A continuous IV infusion of a drug was started at the beginning point of the graph. The concentration of the drug in the plasma was followed over time.

Pralidoxime is able to hydrolyze the phosphate bond and reactivate the enzyme. This works well if the enzyme-phosphate complex has not “aged” (a story too complex to be included in this book, but quite interesting). In addition, because pralidoxime does not cross the blood–brain barrier, it is not effective in reversing the CNS effects of the organophosphates. Atropine (a muscarinic antagonist) is used in organophosphate poisoning because it will block the effects of the excess acetylcholine, but only at the muscarinic receptors.

Inclusion here also makes it easier to learn about these drugs and their side effects. The competitive neuromuscular blocking drugs are used to produce skeletal muscle relaxation. All of these drugs bind to all nicotinic receptors (at the neuromuscular junction and autonomic ganglia) and some actually bind muscarinic receptors to a small extent. The neuromuscular blockers act relatively selectively at the nicotinic receptor at the neuromuscular junction. They vary in their potency and in their duration of action.
