Hello! :) I have never studied vitamin in this way .These were the questions asked during my pharmacology vivas. And I found it fascinating after studying. Q. Which vitamin deficiency is related with lowering of seizure threshold? Ans. Pyridoxine Vit B6 . 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. We know that here the main reason is nicotinic acid (a derivative)  which results in flushing of face. Why? Vasodilation of  cutaneous vessels. So we combine it with specific anti-flushing drug called laropiprant. Q .In hyperemesis gravidarum,what you give for associated Wernicke's encephalopathy following hyperemesis ? Ans. Even I thought of anti-emetics but it came out to be "vitamin B1" . (Everytime Wernicke's encephalopathy doesn't result from alcohol:P) That's for today. Take care. :) -Upy...
