Adverse effects of Cholinergics are? | Bradycardia, hypotension, lacrimation, heart block, vomiting, diarrhea, increased GI activity, intestinal rupture, and increased bronchial secretions |
What are the 2 categories of cholinergics? | Direct acting and Indirect acting |
Direct acting cholinergics mimic the actions of _______________? | Acetylcholine |
Indirect acting cholinergics (anticholinerstase work how? | by inhibiting the break down of acetylcholine |
Bethanecol | (Urecholine)-tx GI and urinary tract atony Class: Autonomic Nervous System Drugs Category: Direct acting cholinergics |
