Study Notes
Botulism Symptoms
- Initial symptoms of botulism include weakness, dizziness, and blurred vision.
- Mr. F discovered the asparagus smelled funny and decided to discard it, suspecting it was spoiled.
Psychopharmacology
- Psychopharmacology focuses on the effects of drugs on the nervous system and behavior.
- The field studies how pharmaceuticals can be used to manage mental disorders like schizophrenia, depression, and anxiety.
Drug Administration Routes
- Common route for drug administration in laboratory animals is injection.
- Oral administration is often used for drugs that may irritate the stomach.
- Intravenous (IV) administration delivers drugs to the brain very rapidly.
- Sublingual administration (under the tongue) allows for quick absorption into the bloodstream.
- The route delivering drugs directly to the brain for antibiotic treatment is via intrathecal administration.
- Routes allowing for slow and prolonged absorption include transdermal patches.
Drug Definitions and Classifications
- A drug is defined in pharmacology as any substance that alters physiological processes.
- Generic substances not affecting physiological processes are not considered drugs.
Effects of Opiates
- Opiates like morphine and heroin produce analgesia and euphoria, strongly affecting the central nervous system.
Drug Absorption and Distribution
- The process of absorption, distribution, metabolism, and excretion of drugs is called pharmacokinetics.
- Drug distribution reflects how effectively a drug reaches its sites of action throughout the body.
- Rapid absorption rates to the brain are primarily influenced by lipid solubility.
- The therapeutic index indicates a drug's safety margin, comparing effective dosage to toxic dosage.
- A drug's effectiveness is best measured by its therapeutic response and patient outcomes.
Drug Affinity and Dosage
- Drug affinity indicates how well a drug binds to its target; higher affinity typically requires lower doses.
- Heroin is more lipid-soluble than morphine, contributing to its strong psychoactive effects.
- Repeated drug administration can lead to tolerance, necessitating higher doses for the same effect.
Safety and Effectiveness
- The margin of safety is a measure reflecting the safe dosage range of a drug relative to its therapeutic effect.
- Research by pharmaceutical companies aims to develop effective medications with favorable safety profiles.
Conclusion
- Differences in a drug's effectiveness may arise from molecular structure, affinity, and routes of administration.
- Understanding these concepts assists in comprehending the roles and impacts of drugs in both medical and psychological contexts.
