Brief summary
The effect of sodium bicarbonate (NaHCO3) administered by gavage on the formation of gastrointestinal stasis and urinary indican excretion was studied in a rat model of myeloablative cytostatic therapy with intravenous cyclophosphamide (CP). The introduction of CP at a dose of 390 mg/kg led to the development of gastrointestinal stasis within 24 hours with a predominance of gastrostasis and an increase in indican excretion. The introduction of NaHCO3 into the stomach of rats 30 minutes before and immediately after CP at a dose equivalent to 350 ml of its 4% solution for humans alleviated the manifestations of gastrostasis and overgrowth of indole-producing gastrointestinal microflora. The presented approach to emergency pharmaceutical prevention of gastrointestinal complications of myeloablative cytostatic pharmacotherapy is promising for testing when using not only CP as a cytostatic agent, but also other alkylating drugs.
