🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works in the thick ascending limb of the loop of Henle in the kidney. It blocks the sodium-potassium-chloride cotransporter, which reduces the reabsorption of sodium and chloride. This action increases the amount of water and salt excreted in the urine. It also reduces blood pressure by lowering fluid volume and may have some direct effects on blood vessels.

Dosage Information
| Adult Dosage | The usual adult dose of this medicine for edema is 20 mg to 80 mg taken once or twice daily, but the exact dose depends on your condition, kidney function, and response to treatment. For high blood pressure, the dose is often 40 mg twice daily, but it can be adjusted. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not change your dose without consulting your doctor. |

| Elderly Dosage | Elderly patients may be more sensitive to the effects of this medicine, especially dizziness and electrolyte loss. Treatment is usually started at a lower dose and adjusted carefully. Regular monitoring of kidney function and electrolytes is important. |
| Renal Impairment | In patients with kidney disease, higher doses may be needed to achieve the desired effect, but the risk of side effects is also higher. Close monitoring is required. Dose must be individualized by a qualified clinician. |
| Hepatic Impairment | In patients with liver disease, this medicine should be used with caution because it can cause electrolyte imbalances and worsen liver function. Dose adjustment may be needed. Close monitoring is required. |
| Maximum Daily Dose | The maximum daily dose varies depending on the condition and patient response. In adults, doses up to 600 mg per day have been used in some severe cases under close supervision, but the usual maximum is much lower. Dose must be individualized by a qualified clinician. |
