Colchicine交互作用:
CNS depressants :Colchicine may increase sensitivity to the action of CNS depressants. Monitor the patient and adjust the CNS depressant dosage as needed.
| 減弱colchicine作用 | 增強colchicine作用 |
| Acidifying agents :The action of colchicine is inhibited by acidifying agents. Avoid coadministration. | 1.Alkalinizing agents:The action of colchicine is potentiated by alkalinizing agents. Avoid coadministration. 2.Grapefruit juice :Colchicine plasma concentrations may be elevated by grapefruit juice ingestion, increasing the risk of toxicity (eg, myopathy). Advise patients taking colchicine not to consume grapefruit juice. 3.Moderate CYP3A4 inhibitors (eg, aprepitant, diltiazem, erythromycin, fluconazole, fosamprenavir, verapamil) : Colchicine plasma concentrations may be elevated, increasing the risk of toxicity (eg, myopathy). Coadminister with caution, starting at reduced colchicine doses, and increase monitoring of creatine phosphokinase and for adverse reactions. If colchicine toxicity is suspected, discontinue colchicine. 4.Cyclosporine, digoxin, fibric acids (eg, fenofibrate, gemfibrozil), HMG-CoA reductase inhibitors (eg, atorvastatin, fluvastatin, pravastatin, simvastatin) : The risk of myopathy or rhabdomyolysis may be increased. If coadministration cannot be avoided, monitor the patient for signs of any unexplained muscle pain, tenderness, or weakness. If colchicine toxicity is suspected, discontinue colchicine. |

colchicine可用作痛風預防
通常成人一日Colchicine 3~4mg分6~8次口服,但依年齡、症狀得適量增減之。預防發病時,通常成人一日Colchicine 0.5~1mg,有發作之預感時,一次0.5mg口服。

(A)跟(C)基本上相反,先刪掉
秋水仙素是生物鹼,酸化尿液的話,會形成鹽類無法再吸收,濃度下降。
反之,制酸劑鹼化尿液,秋水仙素濃度上升。

慢性痛風也不太會用colchicine
colchicine主要用在急性痛風和預防痛風發作
因為他不能協助減少尿酸,只能抑制發炎
