Myocholine (Bethanechol Chloride)

Bethanechol chloride, the active ingredient in Myocholine, is a cholinergic agonist presented as an oral tablet for oral use. It is used to treat urinary retention, postoperative ileus, and neurogenic bladder by stimulating smooth‑muscle contraction in the urinary and gastrointestinal tracts.

GNH USA supplies Myocholine as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Myocholine (bethanechol) acts on muscarinic receptors to improve smooth‑muscle activity in the urinary and gastrointestinal systems.

- Urinary retention: enhances bladder emptying by stimulating detrusor muscle contraction. - Postoperative ileus: promotes gastrointestinal motility to restore normal bowel function after surgery. - Neurogenic bladder: improves voiding efficiency in patients with neurologic bladder dysfunction.

Myocholine may cause a range of adverse reactions, most of which are related to its cholinergic activity.

Common Side Effects: - Abdominal cramping: discomfort due to increased gastrointestinal motility. - Diarrhea: loose stools resulting from enhanced intestinal activity. - Increased salivation: excess saliva production. - Sweating: heightened sudoriferous gland activity. - Flushing: transient skin redness. - Nausea: mild stomach upset.

Serious or Rare Side Effects: - Bronchospasm: narrowing of airways, especially in patients with asthma. - Severe hypotension: marked drop in blood pressure. - Bradycardia: abnormally slow heart rate. - Seizures: rare neurologic events. - Allergic reactions: rash, itching, or anaphylaxis. - Cardiac arrhythmia: irregular heart rhythm.

Before prescribing Myocholine, clinicians should evaluate patient‑specific factors and monitor for cholinergic excess.

- Renal or hepatic impairment: adjust therapy and monitor function. - Pre‑existing asthma or COPD: use with caution due to risk of bronchospasm. - Mechanical urinary obstruction: avoid as it may worsen obstruction. - Elderly patients: start at lower doses and observe tolerance. - Concomitant anticholinergic drugs: assess for antagonistic effects. - Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Myocholine can interact with several drug classes, requiring careful management.

Major Interactions (Avoid): - Anticholinergic agents (e.g., atropine, scopolamine): block therapeutic effect. - Muscarinic antagonists (e.g., ipratropium): reduce efficacy. - Drugs causing bradycardia (e.g., digoxin): may exacerbate heart‑rate slowing.

Moderate Interactions (Monitor Closely): - General anesthetics: may potentiate cholinergic responses. - Opioids: additive constipation may mask gastrointestinal effects. - Antihypertensives: possible additive hypotensive effect. - Diuretics: monitor electrolytes and blood pressure. - NSAIDs: watch for gastrointestinal irritation.
