Granisetron primarily functions as a serotonin 5-HT3 receptor antagonist, exerting its antiemetic effects by blocking the action of serotonin at these receptors. By antagonizing the 5-HT3 receptors, granisetron inhibits serotonin-mediated signaling that contributes to nausea and vomiting. Unlike some other antiemetic drugs, granisetron does not directly affect dopamine receptors (as seen with dopamine receptor antagonists like metoclopramide) or muscarinic receptors (as seen with anticholinergic drugs like scopolamine). Its specificity for serotonin receptors makes it a valuable option for managing chemotherapy-

Vitamin K2 (Menaquinone): K vitamins are a group of fat-soluble vitamins. The two most important forms found in food are vitamin K1 (Phylloquinone) and Vitamin K2 (Menaquinone). Supplemental Vitamin K2 exists in several forms, but the most common ones are the menaquinone-4 (MK-4) and menaquinone-7 (MK-7). MK-4 is normally synthesized from all types of vitamin K 1 in certain animal tissues. MK-7 and other long-chain Menaquinones are different from MK-4 in that they are not produced by human tissue, but are generated
