貓糖尿病新口服治療選擇
SGLT2抑制劑為糖尿病貓提供新的口服治療選擇。了解其作用方式及預期效果。
一种治疗猫糖尿病的革命性新疗法已经问世：SGLT2 抑制剂（钠-葡萄糖协同转运蛋白 2 抑制剂）。与必须每天注射两次的传统胰岛素注射不同，SGLT2 抑制剂是每天一次随食物服用的口服药物。它们的作用是防止肾脏重新吸收葡萄糖，从而使多余的血糖通过尿液排出体外。这代表了几十年来猫糖尿病治疗的最大进步。资料来源：临床医生简介，2026 年 5 月。
要点
- SGLT2 inhibitors (bexagliflozin, velagliflozin) are oral once-daily medications — no injections needed
- They work differently from insulin: instead of replacing insulin, they help the body remove excess glucose through urine
- Studies show 70-76% of newly-diagnosed diabetic cats achieve normal blood sugar within 30 days
- The most significant risk is diabetic ketoacidosis (5-6% of cats), usually within the first 2 weeks
- Not suitable for cats with severe diabetes, significant weight loss, or ketosis — these cats need insulin
- Requires careful patient selection and monitoring, especially during the first month of treatment
How SGLT2 Inhibitors Work
Normally, the kidneys filter glucose from the blood and reabsorb most of it back into circulation. SGLT2 inhibitors block this reabsorption process, causing excess glucose to be excreted in urine instead of building up in the bloodstream. Unlike insulin, SGLT2 inhibitors don't replace the hormone — they work with the body's existing insulin production. This means cats must still have some functional insulin production for the medication to work safely.
Effectiveness
Clinical studies show impressive results: polydipsia (excessive thirst) and polyuria (excessive urination) improved in over 50% of cats within one week. Serum fructosamine (a measure of average blood sugar) returned to normal within 30 days in approximately 70% of newly-diagnosed diabetic cats. Peripheral neuropathy (nerve damage causing flat-footed walking) resolved in 75% of affected cats after 6 months. One study showed velagliflozin was actually more effective than twice-daily insulin injections.
Important Risks and Monitoring
The most serious risk is diabetic ketoacidosis (DKA), which occurs in approximately 5-6% of cats, usually within the first 2 weeks of treatment. DKA can occur even when blood sugar appears normal (euglycemic DKA). This is why close monitoring during the first month is critical — your vet will check blood glucose, ketones, and overall health frequently. Mild diarrhea occurs in 30-50% of cats but is usually self-limiting. Cats that don't respond adequately should be transitioned to insulin.
Is Your Cat a Candidate?
SGLT2 inhibitors are appropriate for most newly-diagnosed diabetic cats that still have viable pancreatic beta cells (produce some insulin). They are NOT suitable for: cats with ketosis (elevated blood ketones), severe weight loss, dehydration, or significant comorbidities. A thorough evaluation including physical exam, bloodwork, urinalysis, and ketone testing is required before starting treatment. Cats with pre-existing kidney or liver disease require extra caution.
何时立即去看兽医
- Your cat is showing signs of diabetes — increased thirst, urination, appetite, and weight loss
- Your diabetic cat on insulin is struggling with twice-daily injections
- You want to discuss whether SGLT2 inhibitors are appropriate for your cat
- Your cat on SGLT2 inhibitors shows decreased appetite, vomiting, or lethargy (possible DKA)
- Your cat's diabetes is not well-controlled on current treatment
- Your cat has developed flat-footed walking (plantigrade stance) — a sign of diabetic neuropathy
