Adverse effects
Mechanism of action
- prevents precipitation of calcium in urine
- makes urine less acidic, thus also reduces risk uric acid stones & cystine stones[5]
- increases bone mineral density*[3], citrate contributes (KCl does not show same effect)
- diminishes systolic & diastolic blood pressure* due to K+[3]
* in postmenopausal women
