You are a medical pharmacology expert. Using the medical library database (query_library_db) and read_file tools, research the following anesthetic drugs in depth: **Propofol, Fospropofol, and Thiopental**. Focus on Katzung, Lippincott, and any other pharmacology textbooks available. For EACH drug, provide: 1. Drug class and chemical nature 2. Mechanism of action (detailed - WHY it works, not just what receptor) 3. Pharmacokinetics (absorption, distribution, metabolism, elimination - with WHY, e.g., why is onset fast? why is duration short?) 4. Pharmacodynamics / clinical effects (CNS, cardiovascular, respiratory) 5. Clinical uses / indications 6. Adverse effects (with mechanistic explanations for WHY each occurs) 7. Contraindications 8. Drug interactions 9. Unique/special features that distinguish it from others in its class 10. Comparison points between the three drugs Search the database first: - SELECT title, speciality, file_path FROM v_book_overview to see available books - Use paragraphs_fts to search for 'propofol', 'fospropofol', 'thiopental' - Use headings_fts to find relevant chapters - Read the actual file content for detailed information Return COMPREHENSIVE, DETAILED notes suitable for medical students. Include the "why" behind every mechanism and effect. Cite book titles in your answer.

You are a medical pharmacology expert. Using the medical library database (query_library_db) and read_file tools, research the following drugs in depth: **Etomidate, Nitrous Oxide, and Dantrolene**. Focus on Katzung, Lippincott, and any other pharmacology textbooks available. For EACH drug, provide: 1. Drug class and chemical nature 2. Mechanism of action (detailed - WHY it works, not just what receptor) 3. Pharmacokinetics (absorption, distribution, metabolism, elimination - with WHY) 4. Pharmacodynamics / clinical effects 5. Clinical uses / indications 6. Adverse effects (with mechanistic explanations for WHY each occurs) 7. Contraindications 8. Drug interactions 9. Unique/special features 10. For Dantrolene: special note on malignant hyperthermia mechanism and treatment Search the database: - SELECT title, speciality, file_path FROM v_book_overview - Use paragraphs_fts to search for 'etomidate', 'nitrous oxide', 'dantrolene', 'malignant hyperthermia' - Use headings_fts to find relevant chapters - Read actual file content Return COMPREHENSIVE, DETAILED notes suitable for medical students. Include the "why" behind every mechanism and effect. Cite book titles.

You are a medical pharmacology expert. Using the medical library database (query_library_db) and read_file tools, research the following drugs/compounds in depth: **Warfarin, Clopidogrel, and Aminocaproic Acid**. Focus on Katzung, Lippincott, and any other pharmacology textbooks available. For EACH drug, provide: 1. Drug class and chemical nature 2. Mechanism of action (very detailed - WHY it works at molecular level) 3. Pharmacokinetics (with reasons WHY for each property) 4. Clinical uses / indications 5. Adverse effects (with WHY mechanistically) 6. Contraindications 7. Drug interactions (especially for warfarin - very important clinically) 8. Monitoring parameters 9. Reversal agents 10. Unique features For Warfarin specifically: explain the vitamin K cycle, why it has a delayed onset, why INR is used for monitoring, why it has so many drug interactions, genetic factors (CYP2C9, VKORC1). For Clopidogrel: explain the prodrug activation, P2Y12 receptor, irreversibility, and why loading doses are used. For Aminocaproic acid: explain fibrinolysis mechanism, how it inhibits it, and clinical uses. Search the database: - SELECT title, speciality, file_path FROM v_book_overview - Use paragraphs_fts to search for 'warfarin', 'clopidogrel', 'aminocaproic' - Read actual file content Return COMPREHENSIVE, DETAILED notes. Include all "whys". Cite book titles.

You are a medical pharmacology expert. Using the medical library database (query_library_db) and read_file tools, research the following GI peptides/hormones and one Parkinson's drug in depth: **Cholecystokinin (CCK), Somatostatin, GLP-2 (Glucagon-Like Peptide-2), VIP (Vasoactive Intestinal Peptide), and Entacapone**. Focus on Katzung, Lippincott, Ganong's physiology, and any other textbooks available. For EACH compound, provide: 1. Chemical nature / classification 2. Source/where it is produced (for peptides: which cells, which organs) 3. Mechanism of action (receptor type, signal transduction - WHY it produces its effects) 4. Physiological/pharmacological effects (detailed - all organ systems affected) 5. Clinical uses / therapeutic applications 6. Adverse effects 7. Regulation (what stimulates/inhibits release) 8. Clinical significance / disease associations For Entacapone specifically: - COMT inhibition mechanism (WHY this prolongs levodopa effect) - Role in Parkinson's treatment - Comparison with tolcapone - Side effects (especially diarrhea, urine discoloration) - Drug interactions Search the database: - SELECT title, speciality, file_path FROM v_book_overview - Use paragraphs_fts to search for 'cholecystokinin', 'somatostatin', 'GLP-2', 'vasoactive intestinal', 'entacapone', 'COMT' - Use headings_fts to find relevant GI physiology and pharmacology chapters - Read actual file content Return COMPREHENSIVE, DETAILED notes. Include all "whys". Cite book titles.
