Digoxin can be used to treat heart failure when symptoms remain despite the use of other drugs. Select one or more newsletters to continue. F = Bioavailability factor.
The parameters are found in the drug model database and are fully user-editable. * 0.25 mg tablets with 80% bioavailability or 0.2 mg LANOXICAPS ® Capsules with 100% bioavailability..
Bioavailability was determined from area under the eighthour serum concentration curve and six-day cumulative urinary excretion of digoxin. Calculations Based on Steady-State Serum Digoxin Concentrations. Introduction. When taken with
You can tailor each drug model to fit your patient population, or you can create your own models.
For digoxin tablets Variability in the bioavailability of digoxin tablets was recognized as a clinical problem in the early 1970s.
It is also used for atrial fibrillation to reduce the ventricular rate. • Dosage calculations are based on a steady state volume of distribution of approximately 5 L/kg for digoxin, which is used to convert serum. 1 For heart failure, the recommended range for the serum digoxin concentration has been reduced over the past decade from 0.8–2.0 nanogram/mL to 0.5–0.9 nanogram/mL. See the 1.

Absorption of digoxin from LANOXIN Tablets has been 48 demonstrated to be 60% to 80% complete compared to an identical intravenous dose of digoxin 49 (absolute bioavailability).
There was no significant difference in bioavailability among elixir and rapid-dissolution tablets.
Available for Android and iOS devices.
The digoxin model is not hard-coded into the program. {66} {67} {68} These differences in bioavailability were reported among different brands of digoxin tablets as well as among different lots of digoxin tablets produced by the same manufacturer. Estimate Volume of Distribution (Jusko Equation - see above)Cp = Steady-state serum digoxin concentration (mcg/l) When LANOXIN Tablets are taken after meals, the rate of absorption 50 is slowed, but the total amount of digoxin absorbed is usually unchanged.
The great variability in serum digoxin concentrations in patients given the same dose has led to the development of nomograms and equations designed to estimate the optimal digoxin dosage. Slow-dissolution tablets … MD = (Cl x Cp x tau) / F. where Cl = Digoxin clearance (l/hr) Cp = target serum level (mcg/l) tau = dosing interval (hours) F = bioavailability …
Calculate Maintenance Dose .
These methods include factors such as age, weight, sex, renal function, disease state, and concurrent drug therapy to calculate the dose and corresponding serum concentration.
Estimate Volume of Distribution (Jusko Equation)Vd = 226 + [(298 x CrCl) / (29.1 + CrCl)] x (BSA / 1.73)where A = 0.88, for patient with Acute CHF, otherwise=11. Table 2 gives dosage estimates in number of vials for adult patients for whom a steady-state serum digoxin concentration is known. digoxin concentrations to total body burden of digoxin in milligrams.
Cp = Steady-state serum digoxin concentration (mcg/l) tau = Dosing interval (hours) 3. The volume of distribution is a population average and may vary among individuals.
