Study Notes
Toxic Effects of Salicylic Acid
- Mild toxicity known as Salicylism characterized by symptoms such as tinnitus, headache, nausea, and dimness of vision.
- Severe toxic reactions require immediate hospital care and intravenous fluids to correct acidosis and electrolyte imbalances.
Treatment for Hypoglycemia and Hypokalemia
- Managed symptomatically with the administration of glucose and potassium, alongside analgesics if necessary.
Administration and Metabolism
- Salicylic acid is administered orally and is primarily absorbed in the small intestine.
- Metabolized mainly in the liver, producing salicyluric acid, ether phenolic glucuronide, and acyl or ester glucuronide.
- Small amounts are converted to gentistic acid and genitsuric acid.
Excretion
- Predominantly excreted through the kidneys, with minimal salicylate found in feces.
Uses of Salicylic Acid
- Acts as an analgesic for mild to moderate pain by inhibiting prostaglandin synthesis, lowering pain sensitivity.
- Important for anti-inflammatory effects by inhibiting prostaglandin production, enhancing vasodilation.
Analgesic Mechanism of Acetylsalicylic Acid (Aspirin)
- Provides analgesia through the inhibition of prostaglandin synthesis, decreasing pain-triggering substances.
- Antipyretic effects result from normalized body temperature through hypothalamus action.
Risks of Salicylism
- Symptoms typically subside upon withdrawal; however, lethal doses range from 10 to 30 gm in adults.
- Severe effects include psychological issues, circulatory and respiratory changes.
Adverse Reactions of NSAIDs
- Common side effects include gastrointestinal irritation, pain, and potential bleeding leading to tarry stools.
- Renal effects can lead to renal failure, cystitis, and urinary infections.
Central Nervous System Effects
- CNS side effects may include sedation, dizziness, confusion, mental depression, headache, vertigo, and seizures.
NSAID Mechanism of Action
- NSAIDs reversibly inhibit cyclooxygenase (COX) enzymes, reducing the formation of prostaglandins, which are mediators of inflammation and pain.
Common NSAIDs and Therapeutic Use
- Commonly used NSAIDs include ibuprofen and acetaminophen.
- Therapeutically indicated for osteoarthritis, rheumatoid arthritis, gouty arthritis, fever, dysmenorrhea, and general pain relief in both medical and dental contexts.
Oral Manifestations of NSAID Use
- Include ulcerative stomatitis and gingival ulceration as potential adverse effects from long-term use.
Other Side Effects of NSAIDs
- Potential effects: muscle weakness, ringing in the ears, and blurred vision related to the drugs' pharmacological properties.
