Tri-salt form of metformin
Provided herein are tri-salt compounds comprising a compound having two acidic functional groups and one basic functional groups (e.g., aspartate or glutamate), metformin, and polyunsaturated fatty acids, such as eicosapentaenoate or docosahexaenoate. The salts can be used in the treatment of diabetes, diabetes with concomitant dyslipidemia (e.g., high triglycerides) and diabetes exacerbated cardiovascular complications, such as cardiac arrhythmia, cardiac ischemia, myocardial infarction, cardiomyopathy, and stroke. The compounds of this invention are also useful in treating obesity.
