Document Summary
Pupils dilate, increases ocular pressure: respiratory rate increases, bronchial dilate, heart rate increases, blood pressure increases, gi/gu tract slows down. Pupils constrict, decreases ocular pressure: respiratory rate decreases, bronchial constrict, heart rate decreases, blood pressure decreases, gi/gu speeds up. In the parasympathetic system, acetylcholine is the neurotransmitter innervate cholinergic receptors in organs, tissues, and glands: cholinergic agonists stimulate the parasympathetic system, direct acting: stimulates post-synaptic nerve cell release of ach at receptor site. Management of urinary retention associated with neurogenic bladder. Side effects: n/v/d, cramps, increased salivation, increase sweating, frequent urination, blurred vision. Contraindications: urinary obstruction, severe bradycardia, hypotension, peptic ulcer, copd, Life threatening: heart block, cardiac arrest, acute asthma attacks, circulatory collapse. Constricts the pupils and decreases ocular pressure, treatment for glaucoma by relieving fluid pressure in the eye and to promote miosis in eye surgery and examination. Treatment for myasthenia gravis (pupillary constriction), reversal of anticholinergic drug effects of tca overdose.
