Adverse Effects

Endocrinologic Adverse Effects

Drug-Induced Hyporeninemic Hypoaldosteronism (see Hypoaldosteronism)

• Physiology
  • Class effect, common to all NSAID’s
  • Dose-dependent COX-inhibition -> decreased renal prostaglandin synthesis -> results in drug-induced hyporeninemic hypoaldosteronism
• Clinical
  • Hyperkalemia (see Hyperkalemia)
  • Type 4 Renal Tubular Acidosis (RTA) (see Type 4 Renal Tubular Acidosis)

Gastrointestinal Adverse Effects

Peptic Ulcer Disease (PUD) (see Peptic Ulcer Disease)

• Physiology: class effect, common to all NSAID’s

Pulmonary Adverse Effects

Aspirin-Intolerant Asthma (see Asthma,)

• Physiology: class effect, common to multiple NSAID’s

Drug-Induced Pulmonary Eosinophilia (see Drug-Induced Pulmonary Eosinophilia)

• Associated Agents
  • Acetylsalicylic Acid (Aspirin) (see Acetylsalicylic Acid)
  • Diclofenac (Aclonac, Cataflam, Voltaren) (see Diclofenac)
  • Diflunisal (Dolobid)
  • Fenbufen
  • Fenoprofen (see Fenoprofen): case reports
  • Ibuprofen (Advil, Brufen, Motrin, Nurofen) (see Ibuprofen): case reports
  • Indomethacin (Indocin) (see Indomethacin)
  • Loxoprofen
  • Meloxicam (see Meloxicam)
  • Naproxen (Naprosyn, Aleve) (see Naproxen): appears to be more frequent with naproxen than other NSAID’s
  • Nimesulide
  • Phenylbutazone
  • Piroxicam (Feldene) (see Piroxicam)
  • Pranoprofen
  • Sulindac (Clinoril) (see Sulindac): case reports
  • Tenidap
  • Tiaprofenic Acid
  • Tolfenamic Acid
• Diagnosis
  • Lung Biopsy: poorly defined granulomas with infiltrating eosinophils
• Clinical
  • Cough
  • Dyspnea
  • Fever
  • Peripheral Eosinophilia
  • Pulmonary Infiltrates

Renal Adverse Effects

Acute Kidney Injury (see Acute Kidney Injury)

• xxx

Acute Interstitial Nephritis (see Acute Interstitial Nephritis)

• Physiology: class effect, common to all NSAID’s

Hyperkalemia (see Hyperkalemia)

• Mechanism: due to drug-induced hyporeninemic hypoaldosteronism

Increased Renal Sodium Reabsorption with Peripheral Edema

• Risk Factors
  • Advanced Age
  • Diabetes Mellitus (see Diabetes Mellitus)
  • Volume Contraction
    • Cirrhosis (see End-Stage Liver Disease)
    • Congestive Heart Failure (CHF) (see Congestive Heart Failure)
    • Decreased Sodium Intake
    • Diuretics
• Physiology: decreased PGE2 -> increased renal sodium reabsorption
  • Class Effect: common to all NSAID’s
  • Dose-Dependent Effect
• Clinical: typically occurs during the first week of therapy
  • Exacerbation of Congestive Heart Failure (see Congestive Heart Failure)
  • Hypertension (see Hypertension): usually moderate
  • Peripheral Edema (see Peripheral Edema)
  • Weight Gain (see Weight Gain)

Type 4 Renal Tubular Acidosis (RTA) (see Type 4 Renal Tubular Acidosis)

• Physiology: due to NSAID-induced hyporeninemic hypoaldosteronism
