A pharmacopeia is an officially recognized and legally binding compendium of standards, specifications, and quality control tests for medicines, drug substances (active pharmaceutical ingredients - APIs), excipients, and other pharmaceutical articles. It serves as a public standard to ensure the quality, safety, and efficacy of medicinal products. Key aspects: official recognition public standards. General tests and Assays. Reagents and reference standard. Packaging and labeling Quality control. EX: United States Pharmacopeia (USP), British Pharmacopoeia (BP), Indian Pharmacopoeia (IP) and Japanese Pharmacopoeia (JP). Importance of Pharmacopeia: Ensuring Drug Quality. Promoting Public Health. Facilitating Trade. Guiding Manufacturers. Supporting Regulatory Agencies. Providing Information to Healthcare Professionals. Indian Pharmacopeia: The Indian Pharmacopoeia (IP) is the official book of standards for the quality of drugs manufactured and/or marketed in India. It is published by the...

 Properties of chemotherapeutic agents:  Spectrum of Activity: Broad-spectrum: Effective against a wide range of microorganisms. Narrow-spectrum: Effective against a limited number of microorganisms. 2. Mechanism of Action: Cell wall synthesis inhibition: Disrupting the formation of the microbial cell wall, leading to cell lysis. Protein synthesis inhibition: Interfering with the microbial protein production, halting growth. DNA/RNA synthesis inhibition: Blocking the replication or transcription of microbial genetic material. Metabolic pathway disruption: Interfering with essential metabolic processes in the microorganism. 3. Potency: Minimum Inhibitory Concentration (MIC): The lowest concentration of a chemotherapeutic agent that inhibits the growth of a microorganism. Minimum Bactericidal Concentration (MBC): The lowest concentration of a chemotherapeutic agent that kills the microorganism. 4. Pharmacokinetics: Absorption: How well the chemotherapeutic a...

 History of chemotherapy: The concept of using chemicals to treat disease was emerging at 19th century but initiated at 20th century. World war I was the base for finding that Exposure to mustard gas was found to suppress bone marrow function, leading researchers to investigate its potential in treating leukemia, a cancer of the blood. 1940s: The first true chemotherapy drug, nitrogen mustard, was developed and used to treat lymphoma. 1950s: Folic acid antagonists, like methotrexate, were developed. 1980s and 1990s: New classes of chemotherapy drugs, such as topoisomerase inhibitors and taxanes, were introduced. 21st century: personalized  medicine, tailoring chemotherapy regimens to individual patients based on their genetic makeup and tumor characteristics. Chemotherapeutic agents are drugs used to treat cancer. They work by targeting and killing rapidly dividing cells, a hallmark of cancer. Types of mechanism:   Alkylating agents: These drugs damage DNA, preventing...
