I believe the answer is  Anticholinergic 

Activation of the cholinergic receptor will increase salivation, gastrointestinal motility and relax the muscle of the bladder. If the drug blocking the cholinergic receptor, it will cause the opposite effect. Decreased salivation will result in dry mouth, decreased GI motility will cause constipation and constriction of bladder sphincter muscle cause 
urinary retention.
