Other conditions such as reduced cardiac output and hypertension can result in arrythmias as well. In the treatment of CHF, Lanoxin increases the contractility of the heart by allowing more sodium-calcium exchange, thus more intracellular calcium in the heart muscle. Lanoxin is also used to treat supraventricular arrythmias. It suppresses the conduction in the A-V node to allow a longer refractory period and decrease conduction velocity. This in turn will slow the ventricular rate.
Digoxin is also is associated with an increased incidence of Xerostomia.
Patients taking Digoxin may benefit from saliva substitution products and fluoride treatments. There is also an increased gag reflex related to Digoxin and impression taking may be difficult. There are many drug interactions with Digoxin including OTC preparations such as antacids which reduce the effectiveness of the Digoxin.
