All of the following are features of metoprolol in comparison to propanolol EXCEPT
Metoprolol is a cardio-selective b-blocker and thus is safer than nonselective blockers ( propanolol) in diabetics, asthmatics and the patients of peripheral vascular disease (e.g. Raynaud's disease). Due to lack of b2-blocking action, it cannot suppress muscle tremors. Potential to cause bradycardia is similar to non-selective b-blockers. Drugs possessing ISA (like pindolol) are less likely to cause bradycardia.
