Study Notes
Addiction Treatment
- Untreated drug dependence can be dangerous and even fatal if not treated properly
- Treatment may involve hospitalization and the use of substances that mimic the effects of the addicting drug to reduce withdrawal symptoms
- Relapse is common, and treatment may not be successful on the first attempt
Tolerance, Dependence, and Addiction
- Tolerance refers to the decrease in drug response, requiring higher doses
- Dependence refers to physical or psychological symptoms that occur when the body becomes dependent on a substance
- Addiction is characterized by an inability to stop or control substance use despite negative consequences
- Tolerance and dependence can lead to addiction
Dealing with Tolerance
- Approaches to overcome tolerance include:
- Increasing the dose of the drug (although this may lead to more toxicity)
- Stopping drug administration for a period of time (drug holiday)
- Shifting to another drug with the same effect and using the originally used doses
Types of Tolerance
- Pharmacokinetic tolerance: occurs due to increased rate of drug disposition, resulting in decreased drug concentration at the site of action
- Pharmacodynamic tolerance: adaptation of body cells to the drug, resulting in decreased response
Drug Resistance
- Definition: decrease in drug response on repeated administration during the course of therapy
- Types of drug resistance:
- Due to body-drug interaction (tolerance)
- Due to microorganisms or cancer cells (resistance)
Key Differences
- Tolerance: decrease in drug response due to body-drug interaction
- Resistance: ability of microorganisms or cancer cells to resist the effects of a drug
