As a result of an бета-адренорецепторо�� Membrane activated adenilatziklaza and increases intracellular calcium. Beta-adrainomimetiki selective increase the strength and frequency of heart while rasslabla smooth muscle bronchi. The unwanted tachycardia limits their use in kupirovanii bronchoconstriction. Instead, selective beta_2-adrainomimetiki have found widespread application in the treatment of asthma and chronic obstructive lung diseases (chronic bronchitis, emphysema, etc.), as they have fewer side effects (on the heart). Beta_2-adrainomimetiki appoint and dropped, and the interior, but the most effective dose.
