Drugs

Pharmacology

• Pharmacokinetics: the study of how the body absorbs, distributes, metabolizes, and eliminates drugs
  • Absorption: the process by which the body takes in a drug
  • Distribution: the movement of the drug throughout the body
  • Metabolism: the process by which the body breaks down the drug
  • Elimination: the process by which the body removes the drug
• Pharmacodynamics: the study of how drugs interact with the body
  • Mechanism of action: the way a drug produces its effects
  • Receptor binding: the attachment of a drug to a specific receptor in the body
  • Dose-response relationship: the relationship between the dose of a drug and its effect

Drug Interactions

• Types of interactions:
  • Drug-drug interactions: the interaction between two or more drugs
  • Drug-food interactions: the interaction between a drug and a food or nutrient
  • Drug-disease interactions: the interaction between a drug and a disease or condition
• Consequences of interactions:
  • Increased risk of adverse effects
  • Decreased efficacy of one or more drugs
  • Increased risk of toxicity
• Factors influencing interactions:
  • Pharmacokinetic factors: absorption, distribution, metabolism, and elimination
  • Pharmacodynamic factors: mechanism of action, receptor binding, and dose-response relationship

Prescription Management

• Prescription components:
  • Patient information: name, date of birth, address, etc.
  • Prescriber information: name, contact information, etc.
  • Medication information: medication name, dose, frequency, duration, etc.
  • Instructions: specific instructions for taking the medication
• Prescription filling and management:
  • Dispensing: the act of providing a patient with a medication
  • Labeling: the attachment of a label to a medication with instructions for use
  • Counseling: the provision of information and guidance to a patient about a medication
• Medication adherence:
  • Importance: taking medications as directed is crucial for effective treatment
  • Factors influencing adherence: patient education, medication complexity, side effects, etc.

Prescription Drugs

• Definition: Prescription drugs are medications prescribed by a licensed medical professional to treat a specific medical condition.
• Types of prescription drugs:
  • Opioids (e.g., oxycodone, hydrocodone)
  • Stimulants (e.g., Adderall, Ritalin)
  • Depressants (e.g., benzodiazepines, sleep medications)
  • Antidepressants (e.g., SSRIs, MAOIs)
• Misuse and abuse: Taking prescription drugs without a valid prescription, taking more than the prescribed dose, or using someone else's prescription.

Pharmacology

• Definition: Pharmacology is the study of the effects of drugs on living organisms.
• Pharmacokinetics: The study of how the body absorbs, distributes, metabolizes, and eliminates drugs.
• Pharmacodynamics: The study of how drugs interact with the body to produce a response.
• Drug interactions: The effect of combining multiple drugs, which can lead to adverse effects or reduced efficacy.

Rehabilitation

• Definition: Rehabilitation is the process of helping individuals overcome addiction to drugs or other substances.
• Types of rehabilitation programs:
  • Inpatient programs (residential treatment)
  • Outpatient programs (counseling, therapy)
  • Support groups (e.g., NA, AA)
• Rehabilitation stages:
  • Detoxification: Medically supervised withdrawal from the drug.
  • Counseling and therapy: Individual and group sessions to address underlying issues.
  • Relapse prevention: Developing strategies to maintain sobriety.
• Challenges in rehabilitation: Co-occurring mental health disorders, poly-substance abuse, and social and environmental factors.
