Which medication is associated with causing Pseudotumor cerebri (PTC) according to the PTC mnemonic?

Pseudotumor cerebri, also known as idiopathic intracranial hypertension, is a condition characterized by increased intracranial pressure without an identifiable cause. Certain medications have been associated with this condition, and one of the key ones is tetracyclines. These drugs are known to cause increased intracranial pressure, presumably due to various mechanisms such as affecting cerebrospinal fluid dynamics or inflammatory responses.

When recalling which medications are linked to PTC, the mnemonic "PTC" points toward specific drugs that have been reported to have this side effect. Tetracyclines are highlighted specifically because they are not only well-documented in clinical literature for this adverse effect, but they also fit neatly into the mnemonic framework, making them easier to remember for healthcare professionals.

While other medications may have associations with various neurological conditions, they do not have the same level of attribution to Pseudotumor cerebri as tetracyclines do. Understanding this association is crucial for healthcare providers, as recognizing the potential side effects of commonly prescribed medications can help in early diagnosis and management of PTC.
