Resumo
Anticholinergic drugs slow gastrointestinal transit, so solid potassium chloride tablets stay in contact with the mucosa for longer. This raises the risk of local ulceration, bleeding, stricture or perforation.
O que esta interação significa em palavras simples
Oxybutynin and Potassium chloride can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Oxybutynin belongs to Genitourinary; Potassium chloride belongs to Gastrointestinal Tract.
Por que acontece
Reduced GI motility from anticholinergic action prolongs mucosal exposure to the high local potassium concentration released by solid dosage forms.
O que fazer
Use a liquid or effervescent potassium formulation instead of solid oral tablets in patients taking oxybutynin. Report any abdominal pain, vomiting or GI bleeding promptly.
