Vit B1

About Vit B1

Physiological functions: Thiamine pyrophosphate is a coenzyme and the active form of vitamin B. It functions as coenzyme in decarboxylation of a-keto acid and in Hexose Monophosphate shunt.
Deficiency symptoms: In severe vitamin B1 deficiency beriberi develops. It is of two types:
a) Wet beriberi
b) Dry beriberi
Wet beriberi: In this the symptoms are related to the cardiovascular system and they are palpitations, tachycardia, dyspnoea, ECG changes, oedema, and high output cardiac failure.
Dry beriberi: The symptoms and signs are related to the Nervous system. The main features are peripheral neuritis, hyperaesthesia (localized areas) or anaesthesia, there is gradual loss in muscle strength, wrist drop, poor memory, depression, lack of initiative and anorexia.

Mechanism of Action of Vit B1

Thiamine exerts it`s action by influencing carbohydrate metabolism. It combines with ATP to form thiamine pyrophosphate in the body. Thiamine pyrophosphate acts as a coenzyme for carbohydrate metabolism, decarboxylation of ketoacids, and hexose monophosphate shunt. It also have plays some role in neuromuscular transmission.

Vitamin B12 is an essential constituent for growth, cell reproduction, hematopoiesis, and nucleoprotein and myelin synthesis. Vitamin B12 is converted in to coenzyme B12 in the tissues which is essential for conversion of methyl-malonate to succinate and synthesis of methionine from homocystine. It is also associated with fat and carbohydrate metabolism and protein synthesis. Cells characterized by rapid division such as epithelial cells, bone marrow, and myeloid cells appear to have greatest requirement of Cyanocobalamin.

Pharmacokinets of Vit B12

Absorption: Absorbed irregularly after oral administration and absorption depends on Ca and intrinsic factor. It is also administered subcutaneously and intramuscularly.
Distribution: Distributed in to liver, bone marrow, and other tissues. It crosses the placenta and appears in breast milk.
