Travel Destination Syndromes and Schizophrenia

Antipsychotic levels clarify adherence, guide dose escalation up to a point of futility, and offer more than pharmacogenetic testing, says Jonathan Meyer, MD.

How to interpret antipsychotic drug levels in schizophrenia: when labs mislead, when levels help adherence and toxicity checks, and why serial monitoring matters.

Therapeutic drug monitoring takes guesswork out of antipsychotic care—spotting nonadherence, guiding dose targets, and defining response thresholds and the “point of futility” in schizophrenia.

FDA approves monthly subcutaneous olanzapine LAI Weltruza, expanding schizophrenia treatment options and renewing debate on making long-acting injectables routine.

Once-monthly subcutaneous olanzapine LAI requires no loading doses, oral supplementation, or post-injection monitoring, based on phase 3 SOLARIS data.

Neurosterix advances NTX-253, an oral M4 PAM, into phase 2 for schizophrenia after phase 1 shows promising safety and pharmacokinetics.

Once-monthly subcutaneous olanzapine TEV-749 shows sustained stabilization and remission in schizophrenia, supports direct switching, and avoids post-injection monitoring.

Real-world data links once-monthly Uzedy to fewer ER visits, better adherence, and lower costs—plus fewer bipolar I relapses when switching from pills.
