Bchol Uses, Dosage, Side Effects, Food Interaction and all others data.
Bchol is a synthetic ester that was initially synthesized in 1935. As a cholinergic agent, bethanechol is similar in structure and pharmacological function to acetylcholine and is used in specific cases when stimulation of the parasympathetic nervous system is necessary. For example, bethanechol is readily used to treat postoperative or postpartum urinary retention. An advantage of bethanechol is that in contrast to acetylcholine, bethanechol is not degraded by cholinesterase allowing its effects to be longer-lasting.
Bchol is selective for muscarinic receptors and has little to no impact on nicotinic receptors. The charged quaternary amine in the structure of bethanechol prevents it from crossing the blood-brain barrier which minimizes central nervous system related adverse effects.

Uses
Bchol is a muscarinic agonist used to treat postoperative and postpartum nonobstructive functional urinary retention and neurogenic atony of the bladder with retention.
Bchol is indicated for the treatment of acute, functional postpartum and postoperative urinary retention. It is also indicated for the treatment of neurogenic atony of the bladder with retention.
Bchol is also used to associated treatment for these conditions: Acute post-operative Urinary retention, Neurogenic atony of the urinary bladder, Non-obstructive postpartum urinary retention
How Bchol works
Bchol is a direct muscarinic agonist and stimulates the parasympathetic nervous system by binding to postganglionic muscarinic receptors.
Though there are 5 types of muscarinic receptors (M1, M2, M3, M4, M5), binding of bethanechol to M3 is most clinically significant since M3 receptors are present in intestinal smooth muscle and the bladder. The cholinergic effects of bethanechol lead to increased detrusor muscle tone to promote bladder emptying and increased smooth muscle tone which restores gastrointestinal peristalsis and motility.
As a result of selectivity for muscarinic receptors, bethanechol produces minimal to no nicotinic effects.
Toxicity
Symptoms of bethanechol overdose include nausea, vomiting, abdominal discomfort, salivation, sweating, and flushing of the skin.
In case of overdose, atropine sulfate is available as an antidote and although subcutaneous administration is preferred, it may be given intravenously in emergencies. In adults, the recommended dose of atropine is 0.6 mg and may be repeated every 2 hours based on the patient’s response. In infants and children up to 12 years of age, the recommended dose of atropine is 0.01 mg/kg (maximum single dose = 0.04 mg) and may be repeated every 2 hours until the desired response is achieved or until adverse effects of atropine limit usage.
In mice, the oral LD50 of bethanechol is 1510 mg/kg.
Food Interaction
- Take on an empty stomach. Nausea and vomiting may occur if taken after food.
Bchol Hypertension interaction
[Major] The use of cholinergic agonists, such as bethanechol and pilocarpine, is contraindicated in patients with pronounced bradycardia, hypotension

Bchol Disease Interaction
Major: bronchospasm, cardiac dysfunction, GI/bladder neck obstruction, hyperthyroidism, parkinsonism, seizure disorders
Elimination Route
After oral administration of bethanechol, maximum effectiveness of the drug on the bladder and GI tract typically occur after 60-90 minutes; however, effects may present as early as 30 minutes after administration. The duration of action of a typical oral dose of bethanechol is around 1 hour while higher doses (300-400 mg) may be effective for up to 6 hours.
Subcutaneously administered bethanechol produces effects more rapidly after 5-15 minutes with maximum effectiveness achieved after 15-30 minutes. The effects of subcutaneous bethanechol subside within 2 hours of administration.
