<prompt> All of the following are features of metoprolol in comparison to propanolol EXCEPTIt is ineffective in suppressing muscle tremorIt is safer in diabeticsIt is less likely to cause bradycardiaIt is less likely to worsen Raynauds disease  <response>: 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. Raynauds 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.
