More than what you know about vitamins!

Hello! :)

These were the questions asked during my pharmacology vivas. And I found it fascinating after studying. I have never studied these points about vitamins before! 

Q. Which vitamin deficiency is related with lowering of seizure threshold?

Ans. Pyridoxine Vitamin B6. 

Why? As it is associated with synthesis of neurotransmitter GABA. Therefore, it is indicated during isoniazid induced convulsions. :)

Q. Why laropiprant (20mg) + Niacin (1g) is used in combination?

Ans. Nicotinic acid (a derivative) results in flushing of face.

Why? Vasodilation of cutaneous vessels.

Therefore, we combine it with specific anti-flushing drug called laropiprant.

Q. In hyperemesis gravidarum, what do you give for associated Wernicke's encephalopathy following hyperemesis? 

Ans. I thought of anti-emetics at first but the answer is vitamin B1. (Wernicke's encephalopathy doesn't always result from alcohol :P )

That's for today.
Take care. :)
