์์ฉ ๊ธฐ์ : - **Synthesis Pathway**: Synthesized *in vivo* from **methionine** and **cysteine** via the enzyme **cysteinesulfinic acid decarboxylase (CSAD)** (a process requiring **Vitamin B6**). - **Bile Acid Conjugation**: Crucial for fat digestion. Cats use taurine almost exclusively for this process, leading to obligate loss in feces. - **Cardiac Function**: Modulates **calcium flux** across cell membranes โ provides positive inotropic activity without altering the resting membrane potential, and modulates ionic currents. - **Neuromodulation**: Stabilizes neuronal membranes and exerts a **GABA-like inhibitory effect** in the CNS, which may help raise the seizure threshold and reduce seizure activity. - **Platelet Function**: Reduces platelet aggregation via calcium modulation.

- For taurine-deficiency related cardiomyopathy ยท 250 mg (per cat) PO q12-24h ยท PO ยท q12-24h ยท Because taurine is safe and inexpensive, recommend using for any case of myocardial failure.
- Complementary therapy for seizures ยท 500 mg per cat PO twice daily ยท PO ยท q12h ยท 'May' help decrease seizure activity
- For adjunctive treatment of hepatic lipidosis ยท 250-500 mg/day ยท PO ยท q24h ยท Taurine may be hepatoprotective and is required for bile conjugation. Cats with hepatic lipidosis waste taurine in their urine.
- For taurine-deficiency related cardiomyopathy in American Cocker Spaniels ยท 500 mg PO q12h (with 1 gram of carnitine PO q12h) ยท PO ยท q12h
- Complementary therapy for seizures ยท 400 mg/40 lbs of body weight PO twice daily ยท PO ยท q12h ยท 'May' help decrease seizure activity
- For taurine-related cardiomyopathy ยท 500-1500 mg (total dose) PO per day ยท PO ยท q24h
- Dilated cardiomyopathy ยท 500-1000 mg PO q8-12h for dogs weighing under 25 kg and 1-2 grams PO q8-12h for dogs weighing > 25 kg ยท PO ยท q8-12h ยท Recommended for all American Cocker spaniels; consider in animals with DCM and cysteine/urate urolithiasis (e.g., English Bulldogs, Dalmatians); consider in golden retrievers, Newfoundlands, Portuguese water dogs.

- Clinical efficacy (improvement in cardiac function, seizure frequency, or hepatic markers)
- Taurine levels (whole blood levels preferable to plasma/serum levels; avoid hemolysis or collection of the buffy coat as it will negate the results)

Toxic potential appears to be very low. No specific acute toxicity information is available, but massive overdoses are likely to be excreted renally without significant harm.
