Drug interactions can have a significant clinical impact on patients and can be extremely dangerous or even harmful. A common antiarrhythmic medication for treating cardiac arrhythmia is amiodarone. Amiodarone has a potent inhibitory effect on the CYP2C9 and CYP3A4 isoenzymes. Similar to this, the isoenzymes CYP2C9 and CYP3A4 metabolise anti-diabetic medications such rosiglitazone, pioglitazone, repaglinide, and nateglinide. CYP3A4breaks down sitagliptin and teneligliptin. Glibenclamide and glimepiride are bothmetabolised by CYP2C9 and CYP3A4, respectively. A pharmacological interaction between amiodarone and antidiabetic drugs is therefore entirely possible. Therefore, the goal of the current investigation is to comprehend any potential interactions between amiodarone and antidiabetic drugs.
