Mr Johnson was suffering from urinary retention secondary to a hypoactive bladder. Bethanecol (chloride) is a parasympathomimetic agent that binds to muscarinic ACH receptors. It mimics the action of ACH in causing the bladder muscles to constrict (contract) and increases the expulsion of urine and the degree of emptying of the urinary bladder.

Work Step by Step

Bethanecol increases the force of contraction of muscles of the urinary bladder. This action causes more thorough emptying of the bladder. some Averse effects that the patient might experience are increased sweating, cramping/pain, decreased blood pressure, dizziness, diarrhea, possible inappropriate penile erection, and sweating.
