Digicitrin is used in the pharmaceutical industry as a starting material for producing cardiac drugs. It helps regulate heart muscle function and increase the heart's contractile force, making it useful in treating heart failure or cardiac arrhythmias. Additionally, studies indicate that digicitrin exhibits some antibacterial and antiviral activity, suggesting potential for development as an antimicrobial agent in the future. However, it must be used with caution due to its narrow therapeutic index, and overdose may lead to toxicity affecting the cardiovascular and nervous systems. Primarily utilized in pharmaceutical and biochemical research settings.
