How do pharmacokinetics of ivermectin differ between oral tablet, paste, topical and injectable formulations across species?

Ivermectin’s pharmacokinetics are dominated by slow absorption, wide tissue distribution, low metabolic clearance and slow excretion, but those broad traits are heavily modulated by route and formulat...

Are there published human case reports with numeric CSF or brain tissue ivermectin concentrations, and where can the raw data be accessed?

Published human case reports do include numeric measurements of ivermectin in cerebrospinal fluid (CSF): at least one peer‑reviewed case reported a CSF ivermectin concentration of 0.14 ng/mL with an a...

What are pharmacokinetic differences of ivermectin in low body weight versus obese patients?

Ivermectin’s pharmacokinetics are shaped by its high lipophilicity, producing clear differences between low‑body‑weight (including undernourished children) and obese subjects: obese individuals tend t...

How does a high-fat meal change the pharmacokinetics of oral ivermectin?

A high‑fat meal can increase systemic exposure to oral ivermectin by improving solubilization and absorption of this lipophilic drug, but the magnitude of that effect is inconsistent across studies an...

How do single-dose versus repeated-dose ivermectin regimens change plasma Cmax and half-life?

Single oral doses of ivermectin produce a dose-proportional peak plasma concentration (Cmax) with a terminal half-life around 18–20 hours after typical human doses, while repeated or multi-day regimen...
