May assist in the management of osteoporosis by preventing urine calciu‫ ش‬loss c. ACE inhibitors and ARBs i. Contraindicated in pregnancy

ii. Contraindicated with bilateral renal artery stenosis iii. Monitor K closely, especially if renal insufficiency exists or another K-sparing drug is in use. iv. The presence of diabetic nephropathy should influence the choice of ACE inhibitor versus ARBs iiv cough with ACEIs stop ACEIs and initiate ARBs

Pregnant women
