2-adrenergicheskih Receptors Antagonists And Stimulate , Influencing On

2-adrenergicheskih receptors antagonists and stimulate , influencing on 2-adrenergicheskie receptors, Located in smooth muscles mucous air lines. Excitation of these receptors increases production of the cyclic (AMP) which in turn forbid Bronchospasm. Recommendations about inhalation forms of preparations 2 -adrenergicheskih receptors are cautious, because Forms of preparations have slower beginning of action and, as a rule, Are connected with the big range of action (and complications!). Short Actions beta2-adrenergicheskie antagonists (=SABAs), type terbutalin'a And albuterol'a, it is often used as necessity to reduce Signs COPD because they operate faster and reach a maximum Effect soon after appointment also provide Effective approximately at 4-6 o'clock. Application terbutalin'a In high doses also have shown that is possible seriously To improve ventilation of lungs even at patients with late stages and Serious forms COPD.
