Different Insulin Preparations  Short Acting  Regular : Rapid acting with 0.5 - 1 hour Duration of Action Lispro : Rapid Acting with 6 - 8 hrs DOA. Insulin Zinc : Insulin Suspension having 6 - 8 DOA  Intermediate Acting Isophane (NPH) : Also Called protamine Hagedorn (NPH) insulin, 18 -24 hrs DOA. Long Acting: Protamine Zinc: DOA in upto 36 hrs Insulin detemir: DOA upto 24 hrs  Insulin degludec: DOA upto 24 hrs  MOA of Insulin  Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood glucose levels.  Here’s how it works: Glucose Absorption:  When carbohydrates are consumed, body breaks them down into glucose, a simple sugar that serves as a vital energy source.  (a) Insulin attaches to insulin receptors of the target cell. (b) Activates a  cascade of signaling leading to the formation of certain protein called GLUT4 which is a glucose transporter protein,   (c) GLUT4 is then  translocated t...

ALKYLATING AGENT  Introduction  Alkylating agents are named because they can add an alkyl group to a molecule. Alkylating agents can add alkyl groups to molecules in a variety of ways. One common way is through a process called nucleophilic substitution . In nucleophilic substitution, an alkylating agent reacts with a molecule that has a nucleophilic atom, such as a nitrogen atom or an oxygen atom. The nucleophilic atom attacks the alkylating agent, and the alkyl group is transferred to the molecule. Definition: An alkylating agent is a substance that causes replacement of hydrogen by an alkyl group especially in a biologically important molecule; specifically : one with mutagenic activity that inhibits cell division and growth and is used to treat some cancers. Mode of Action of Alkylating Agents:  Alkylating agents are a type of anticancer drugs that work by damaging the DNA of cancer cells and preventing them from replicating .  They have a chemical structur...

ANTIMETABOLITES  Antimetabolites are a type of chemotherapy drug that work by interfering with the DNA replication process in cancer cells. They mimic the structure of essential molecules that cancer cells need to replicate their genetic information and prevent them from creating the enzymes they need to divide.  These compounds are known as Antimetabolites because they inhibits the metabolic conversion of certain Chemicals (i.e. Folic Acid) to compounds which are essential for synthesis of DNA (Replication).
