                     Corticosteroids should be discontinued gradually if used chronically
                     ******** baseline weight, BP, Pulse & temperature
                     Frequently take BP, monitor body weight - signs of Na+ & H2O retention

                      Digoxin

                      Trade name: Lanoxicaps, Lanoxin, Novo-Digoxin (CAN)

                      Dg classes
                      Cardiac glycoside
                      Cardiotonic agent
                      Pregnancy: (Category C)

                      Therapeutic actions
                      Increases intracellular calcium and allows more calcium to enter the myocardial cell during depolarization via a sodium---potassium pump mechanism; this increases force of contraction (positive inotropic effect), increases renal perfusion (seen as diuretic effect in patients with CHF),decreases heart rate (negative chronotropic effect), and decreases AV node conduction velocity

                      Indications
                      CHF
                      Atrial fibrillation
                      Atrial flutter
                      Paroxysmal atrial tachycardia

                      Dose

                      by mouth, rapid digitalization, 1–15 mg in divided doses over 24 hours; less urgent digitalization, 250–500 micrograms daily (higher dose may be divided), Maintenance, 625–500 micrograms daily (higher dose may be divided) according to renal function and, in atrial fibrillation, on heart-rate response; usual range, 125–250 micrograms daily (lower dose may be appropriate in elderly)
                      Emergency loading dose by intravenous infusion, 075–1 mg over at least 2 hours then maintenance dose by mouth on the following day

                      Contraindications
                      Contraindications: allergy to digitalis preparations, ventricular tachycardia, ventricular fibrillation, heart block, sick sinus syndrome, IHSS, acute MI, renal insufficiency and electrolyte abnormalities (decreased K+, decreased Mg++, increased Ca++)
                      Use cautiously with pregnancy and lactation

                      Side effects
                      CNS: Headache, weakness, drowsiness, visual disturbances
                      GI: GI upset, anorexia
                      CV: Arrhythmias

                      Nursing Considerations
                      Monitor apical pulse for 1 min before administering; hold dose if pulse <60 in adult or <90 in infant, retake pulse in 1 h If adult pulse remains <60 or infant <90, hold dg and notify prescriber Note any change from baseline rhythm or rate
                      Check dosage and preparation carefully
                      Avoid IM injections, which may be very painful
                      Follow diluting instctions carefully, and use diluted solution promptly
                      Avoid giving with meals; this will delay absorption
                      Have emergency equipment ready; have K+ salts, lidocaine, phenytoin, atropine, and cardiac monitor on standby in case toxicity develops
                      Monitor for therapeutic dg levels: 05---2 ng/mL

                        Therapeutic actions
                        Positive inotropic effects are mediated by β1- adrenergic receptors in the heart; increases the force of myocardial contraction with relatively minor effects on heart rate, arrhythmogenesis; has minor effects on blood vessels

                        Indications
                        For inotropic support in the short-term treatment of adults with cardiac decompensation due to depressed contractility, resulting from either organic heart disease or from cardiac surgical procedures
                        Investigational use in children with congenital heart disease undergoing diagnostic cardiac catheterization, to augment CV function

                        Dosage
                        Available Forms: Injection 125 mg/mL
                        Administer only by IV infusion
                        Titrate on the basis of the patient's homodynamic/renal response
                        Close monitoring is necessary

                        Adult
                        25---15 µg/kg/min IV is usual rate to increase cardiac output; rarely, rates up to 40 µg/kg per minute are needed

                        IV facts
                        Preparation: Reconstitute by adding 10 mL Sterile Water for Injection or 5% Dextrose Injection to 250-mg vial If material is not completely dissolved, add 10 mL of diluent Further dilute to at least 50 mL with 5% Dextrose Injection, 09% Sodium Chloride Injection, or Sodium Lactate Injection Store reconstituted solution under refrigeration for 48 h or at room temperature for 6 h Store final diluted solution in glass or via flex container at room temperature Stable for 24 h Do not freeze (Note: dg solutions may exhibit a color that increases with time; this indicates oxidation of the dg, not a loss of potency

                        Infusion: May be administered through common IV tubing with dopamine, lidocaine, tobramycin, nitropsside, potassium chloride, or protamine sulfate Titrate rate based on patient response--P, BP, rhythm; use of an infusion pump is suggested
                        Incompatibilities: Do not mix dg with alkaline solutions, such as 5% Sodium Bicarbonate Injection; do not mix with hydrocortisone sodium succinate, cefazolin, cefamandole, neutral cephalothin, penicillin, sodium ethacrynate; sodium heparin
                        Y-site Incompatibilities: Do not mix with acyclovir, alteplase, aminophylline, foscarnet

                        Adverse effects

                        CNS: Headache
                        GI: Nausea
                        CV: Increase in heart rate, increase in systolic blood pressure, increase in ventricular ectopic beats (PVCs), anginal pain, palpitations, shortness of breath

                        Clinically important interactions
                        Dg-dg
                        Increased effects with TCAs (eg, imipramine), furazolidone, methyldopa
                        Risk of severe hypertension with β-blockers
                        Decreased effects of guanethidine with dobutamine

                        Nursing Considerations
                        Arrange to digitalize patients who have atrial fibrillation with a rapid ventricular rate before giving dobutamine--dobutamine facilitates AV conduction
                        Monitor urine flow, cardiac output, pulmonary wedge pressure, ECG, and BP closely during infusion; adjust dose/rate accordingly
