Study Notes

Treatment Overview

NSAIDs: Ibuprofen, Naproxen, Diclofenac
- Mechanism: Decrease inflammation and pain by inhibiting COX enzymes.
- Benefits: Alleviate symptoms effectively.
- Side Effects: Gastrointestinal irritation and potential renal complications with long-term use.
Corticosteroid Injections
- Indication: For severe or persistent inflammation.
- Mechanism: Strong local anti-inflammatory effect by suppressing immune response.
- Benefits: Reduce swelling and intense pain effectively.
- Side Effects: Risk of local infections and tissue weakening at injection site.
Rest and Physical Therapy
- Benefits: Support healing and prevent recurrence of pain through reduced strain on affected areas.

Rhinitis

Symptoms: Include runny nose, nasal congestion, sneezing, itchy sensations in nose/eyes/throat, and postnasal drip.
Treatment Options:
- Antihistamines: Loratadine, Cetirizine
  - Benefits: Alleviate sneezing and itchy sensations.
  - Side Effects: Drowsiness varies by medication type.
- Corticosteroid Nasal Sprays: Fluticasone, Mometasone
  - Benefits: Decrease nasal congestion and reduce sneezing.
  - Side Effects: Nasal irritation and occasional nosebleeds.
- Decongestants: Pseudoephedrine, Phenylephrine
  - Benefits: Target and alleviate congestion.
  - Side Effects: May increase blood pressure and cause insomnia.

Sinusitis

Symptoms: Pain and swelling around sinuses, nasal congestion, thick discharge, headaches, reduced sense of smell/taste, fever, and cough.
Treatment Options:
- NSAIDs: Ibuprofen, Naproxen, Diclofenac
  - Benefits: Help relieve pain and symptoms.
- Corticosteroid Nasal Sprays: Fluticasone, Budesonide
  - Benefits: Reduce swelling and congestion.
- Antibiotics: Amoxicillin, Doxycycline
  - Benefits: Address bacterial infections effectively.
  - Side Effects: Potential GI upset and allergic reactions.
- Decongestants: Pseudoephedrine, Phenylephrine
  - Benefits: Provide symptomatic relief from congestion.
- Rest and Hydration
  - Benefits: Essential for effective recovery without side effects.

Postoperative Pain Management

NSAIDs: Ibuprofen, Naproxen, Diclofenac, Aspirin
- Mechanism: Inhibition of COX enzymes reduces prostaglandin production.
- Benefits: Effective for mild to moderate pain and inflammation.
- Considerations: Risk of GI irritation and bleeding; select carefully.
Opioids: Morphine, Oxycodone
- Mechanism: Bind to CNS opioid receptors, altering pain perception.
- Benefits: Effective for moderate to severe pain management.
- Side Effects: Sedation, constipation, and potential for dependence; administered intravenously or orally.
Multimodal Analgesia
- Strategy: Combines different pain medications to improve relief and minimize opioid use.
- Examples: NSAIDs or acetaminophen with opioids for better control.

Chronic Pain Conditions

Non-Opioid Analgesics: Acetaminophen, NSAIDs
- Usage: First-line treatments for osteoarthritis and chronic low back pain.
Vascular Response in Inflammation:
- Vasodilation: Enhances blood flow to affected areas.
- Increased Permeability: Facilitates entry of plasma proteins and leukocytes.
Cellular Response:
- Leukocyte Recruitment: Neutrophils and macrophages migrate to injury sites for cleanup.
- Phagocytosis: Leukocytes engulf and destroy pathogens and debris.

Outcomes of Inflammation

Resolution: Clearance of harmful stimuli and repair of tissues.
Chronic Inflammation: Ongoing damage and repair if stimulus persists.
Fibrosis: Excessive scar tissue formation from connective tissue deposition.
Abscess Formation: Localized pus collection due to infection.

Types of Anti-Inflammatory Agents

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): Reduces inflammation via COX enzyme inhibition.
Corticosteroids: Suppress inflammation and immune response.
Disease-Modifying Anti-Rheumatic Drugs (DMARDs): Target underlying inflammation in chronic diseases.

Detailed NSAID Information

Naproxen:
- Brand Names: Napreben, Nopain DS.
- Uses: Relieves arthritis and menstrual pain.
- Dosage: 250-500 mg every 8-12 hours; Side Effects: Increased cardiovascular risk.
Aspirin:
- Brand Names: Aspicor, Aspicot.
- Uses: Pain relief, anti-inflammatory, anti-platelet action.
- Dosage: 325-650 mg every 4-6 hours; Side Effects: GI bleeding, Reye's syndrome in children.
Diclofenac:
- Brand Names: Voltaren, Cataflam.
- Uses: Pain relief for various conditions.
- Dosage: Depends on indication; Side Effects: GI bleeding, cardiovascular risks.
Celecoxib:
- Brand Names: Celebrex.
- Uses: COX-2 selective, used for arthritis and pain relief.
- Dosage: 100-200 mg once or twice daily; Side Effects: CV risks and contraindicated for sulfa allergy.
Rofecoxib:
- Brand Names: Vioxx.
- Uses: COX-2 selective, similar to Celecoxib.
- Dosage: Varies by condition; Side Effects: Increased heart attack/stroke risk, GI bleeding.

Corticosteroids

Mechanism: Mimic cortisol effects, suppress inflammation and immune response.
Effects: Bind to glucocorticoid receptors, regulate gene expression to influence inflammation, improve cell membrane stability to reduce inflammatory mediator release.
