No influence of antihypertensive agents on plasma free metanephrines.

CONCLUSIONS: The measurement of plasma free MN and NMN with LC-MS/MS is not affected by use of β-blockers, diuretics and ACE inhibitors. Withdrawal of these drugs prior to the quantification of plasma metanephrines is therefore not necessary. PMID: 27291837 [PubMed - as supplied by publisher]
