概覽

車前子殼（通常稱為洋車前子）是一種容積性瀉藥，提取自車前草種子的外殼。在獸醫學中用於管理便秘、改善糞便性狀並增加膳食纖維攝取。

​臨床提示：​ 因為它會吸收大量水分形成黏稠的凝膠，必須確保動物能自由飲水，以防止腸道阻塞。

作用機轉

Acts as a bulk-forming agent that absorbs water in the gastrointestinal tract → increases faecal mass → mechanically stimulates peristalsis. It is moderately fermentable in the colon, and the resultant volatile fatty acids exert an osmotic laxative effect.

飼主須知

車前子是一種天然纖維補充劑，有助於調節寵物的排便。它透過使糞便性狀正常化，對便秘和某些類型的腹瀉都有幫助。

​重要提示：​ 請務必將粉末或顆粒與大量水或濕食混合。切勿直接餵食乾粉，因為它會在喉嚨中膨脹並導致窒息。請確保您的寵物隨時可以喝到新鮮的飲用水。
