According to the manufacturer which of the following medications remains stable for a maximum of four months after the original bottle is opened?

Lunesta (eszopiclone) tablets do not have a defined stability period of four months after opening. Generally, they are stable for a longer duration if stored properly, but specific guidelines for post-opening stability are not provided by the manufacturer in the same way as Pradaxa.

Latuda (lurasidone) tablets also do not have a stability period of four months once the bottle is opened. The manufacturer recommends using the medication within a certain timeframe, but it typically exceeds four months, making it less relevant in comparison to Pradaxa's specific guideline.

Prozac (fluoxetine) capsules are known to have a longer shelf life once opened. The manufacturer indicates that they remain stable for a significantly longer duration than four months, which does not align with the stability requirement specified for Pradaxa.
