is metoprolol a narcotic
Fewer metoprolol-treated patients in the MIAMI trial were given narcotic analgesics (49% of the placebo patients vs 44% of the metoprolol patients, p less than 0.001), nitrates (55% vs 53%, p = 0.10) and calcium-channel blockers (12% vs 9%, p less than 0.001). multivariate analysis disclosed that site of suspected infarction, delay time, entry systolic blood pressure and metoprolol treatment all had a significant effect on the use of narcotic analgesics. There was a nonsignificant tendency for heart rate to be of importance.
