<prompt> All of the following are features of metoprolol in comparison to propanolol EXCEPT:It is ineffective in suppressing muscle tremorIt is relatively safer in diabeticsIt is less likely to cause bradycardiaIt is less likely to worsen Raynauds disease  <response>: Cardioselective b blockers metoprolol, atenolol, acebutolol, bisoprolol, nebivolol. More potent in blocking cardiac b1 than bronchial b2 receptors.Their features are: 1. Lower propensity to cause bronchoconstriction 2. Less interference with carbohydrate metabolism and less inhibition of glycogenolysis during hypoglycaemia--safer in diabetics. 3. Less chances of precipitating Raynauds phenomenon. 4. Noless deleterious effect on blood lipid profile. 5. Ineffective in suppressing essential tremor it occurs through b2 action on muscle fibres. 6. Less liable to impair exercise capacity.
