## **Core Concept**
Intractable hiccups refer to persistent hiccuping that lasts for more than 48 hours, often causing significant distress and disruption to a patient's quality of life. Pharmacological interventions are typically considered when hiccups are refractory to conservative treatments. The primary goal is to interrupt the hiccup reflex arc.

## **Why the Correct Answer is Right**
Baclofen, a **GABA receptor agonist**, is considered the drug of choice for intractable hiccups. It works by enhancing the inhibitory neurotransmission in the central nervous system, which helps in interrupting the hiccup reflex arc. Baclofen has been shown to be effective in treating hiccups due to its action on the brain and spinal cord, influencing the nerves involved in the hiccup reflex.

## **Why Each Wrong Option is Incorrect**
- **Option A:** While certain antipsychotics or antiemetics might have anecdotal reports of effectiveness, they are not considered first-line treatments for hiccups due to their side effect profiles and the availability of more targeted therapies like baclofen.
- **Option B:** This option is blank and cannot be evaluated.
- **Option D:** Similarly, this option is blank and does not provide a valid alternative.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that **baclofen** is not only used for muscle spasticity but also has a unique role in managing intractable hiccups. Its effectiveness in hiccups has been documented in various case reports and small-scale studies, making it a go-to option for this condition.

## **Correct Answer:** C. Baclofen.
