How does rapamycin move through the body in Alzheimer's patients?
Pharmacokinetic analysis of intermittent rapamycin administration in early-stage Alzheimer's Disease
Not medical advice. For informational purposes only. Always consult a healthcare professional. Terms
This study looked at how a drug called rapamycin behaves in the blood of people with early Alzheimer's when taken once a week.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.

Sirolimus stays in your body for a long time—about 2.5 days—so even if you take it just once a week, it might still be active when you work out again.
Taking a weekly 7 mg dose of rapamycin for early Alzheimer's doesn't vary too much from person to person, so doctors might not need to adjust doses or monitor blood levels in future studies.
For people with early Alzheimer’s taking a weekly 7 mg rapamycin pill, checking their blood 48 hours after the dose gives the most consistent results and best predicts their baseline levels—so that’s the best time to test it.
When people with early Alzheimer's take rapamycin once a week, the drug stays in their body about as long as it does in other groups — around 69 hours — which means it leaves the body at a similar rate even with weekly dosing.
People with early Alzheimer’s who take 7 mg of rapamycin every week seem to have low levels of the drug in their blood before their next dose—so low that it probably won’t weaken their immune system.
