概覽
比沙可啶是一種刺激性瀉藥,在獸醫學中主要用於治療便秘,或在手術、X光攝影或內視鏡檢查前排空腸道。
- 臨床要點:由於它是一種刺激性瀉藥,僅應作短期使用。長期使用可能導致依賴性、正常腸道功能喪失以及嚴重的電解質失衡。
作用機制
Bisacodyl acts directly on the enteric nervous system.
- Stimulates mucosal sensory nerve endings → increases parasympathetic reflexes → enhances peristaltic contractions.
- Alters fluid and electrolyte absorption → increases intestinal fluid accumulation, which helps soften the stool and facilitate evacuation.
安全性與警告
禁忌症
- Intestinal obstruction
- Ileus
- Gastrointestinal bleeding
- Severe dehydration
不良反應
- Abdominal cramping
- Diarrhea
- Nausea
- Electrolyte imbalances (with chronic use)
注意事項
Warning: Do not crush or chew enteric-coated tablets. Administer whole to prevent severe gastric irritation.
- Use with caution in dehydrated animals; ensure adequate hydration before and during therapy.
- Avoid concurrent administration with milk or dairy products.
藥物相互作用
Premature dissolution of the enteric coating, leading to severe gastric irritation and vomiting.
Increased gastric pH may cause premature release of the drug in the stomach.
監測
- Fecal output and consistency
- Hydration status
- Electrolytes (if used for prolonged periods)
