Too rapid entry into the circulation would lead to unwanted systemic reactions such as: blockade of inhibitory CNS neurons, manifested by restlessness and seizures (countermeasure: injection of a benzodiazepine); general paralysis with respiratory arrest after higher concentrations.
To empty the urinary bladder (micturition), wall tension is increased by detrusor activation with a concurrent relaxation of sphincter tonus. Activation of ocular parasympathetic fibers (see below) results in narrowing of the pupil and increased curvature of the lens, enabling near objects to be brought into focus (accommodation).

 

Intraocular pressure rises, which must be taken into account during eye surgery. In skeletal muscle fibers whose motor nerve has been severed, ACh receptors spread in a few days over the entire cell membrane. In this case, succinylcholine would evoke a persistent depolarization with contracture and hyperkalemia.
Even after inhalation, effective amounts can reach the systemic circulation and cause side effects (e. g. , palpitations, tremulousness, restlessness, hypokalemia). During chronic administration, the sensitivity of bronchial musculature is likely to decline. d) Theophylline belongs to the methylxanthines.
