Furosemide/Digoxin Topical Gel CLS003

**Semantic type:** Pharmacologic Substance

**Definition:** A topical ionic contra-viral therapy (ICVT) gel-based formulation that combines furosemide, a sulfamoylanthranilic acid derivative and loop diuretic, and digoxin, a cardiac glycoside, with potential antiviral activity. Upon topical administration, furosemide interacts with the cell membrane ion co-transporter, Na+-K+-2Cl-co-transporter-1(NKCC1; SLC12A2) and digoxin reversibly inhibits the sodium/potassium-transporting ATPase, leading to a decrease in potassium influx. This may prevent the replication of certain DNA viruses including human papillomavirus (HPV), that rely on potassium for replication.
