Study Notes
Glaucoma and Drug Contraindications
- Certain drugs are contraindicated for glaucoma patients due to their potential to increase intraocular pressure.
Hyoscyamus Niger
- The shrub Hyoscyamus niger is chiefly associated with the drug atropine.
Atropine Mechanism of Action
- Atropine functions as a competitive antagonist of acetylcholine at muscarinic receptors.
Cycloplegic Refraction
- Cycloplegic refraction was scientifically established by Sir William H. Bates.
Cycloplegic Agents
- Homatropine, a cycloplegic agent, has a greater molecular weight compared to atropine.
Clinical Use of Cycloplegic Drugs
- Cyclopentolate, introduced into clinical practice in 1951, is an important cycloplegic agent.
NSAIDs Classification
- The largest class of NSAIDs includes non-steroidal anti-inflammatory drugs providing both anti-inflammatory and analgesic effects.
Non-Salicylate NSAIDs
- The generic name of a common non-salicylate NSAID designed for rapid absorption is ibuprofen.
Pain Management Drugs
- Acetaminophen is often the first choice for managing mild to moderate pain and enhances the effects of narcotic analgesics in severe pain.
Traditional Adjuvant Analgesics
- Caffeine is a traditional adjuvant commonly included in analgesic combinations, beneficial for certain vascular headache syndromes.
Opioid Standards
- Morphine is considered the standard opioid but is not suitable for outpatient use due to side effects, abuse, and addiction risks.
Pain Reliever Classification
- Pain relievers classified as analgesics work by blocking specific substances responsible for pain and inflammation in the body.
Severe Acute Pain Treatment
- Opioids are the primary choice for treating severe acute pain.
Opioid Combinations
- Codeine is often combined with acetaminophen or aspirin for enhanced analgesic effects.
Aspirin Alternatives
- Non-steroidal anti-inflammatory medications like ibuprofen serve as appropriate alternatives to aspirin for treating mild to moderate pain.
Pain Relief Drug Class
- Analgesics primarily work to relieve pain.
Enhancing Opioid Effects
- Adjuvant medications like gabapentin can enhance the pain-relieving effects of opioids.
Tear Film Composition
- The lipid layer of the tear film is a thin polar portion that reduces evaporation of the tear film.
Aqueous Layer Function
- The aqueous layer of the tear film provides moisture and protection to the ocular surface.
Dry Eye Definition
- Dry eye is defined by the Tear Film & Ocular Surface Society as a disorder caused by tear deficiency or excessive evaporation, leading to ocular surface damage and discomfort.
Artificial Tear Polymers
- Commonly used polymers in artificial tears include cellulose derivatives and synthetic lubricants.
Cellulose-Based Polymers
- Cellulose or vegetable gums are part of the group of polymers used in artificial tears.
Parasympathomimetic Medications
- Pilocarpine is classified as a parasympathomimetic agent with muscarinic secretagogue effects.
Hyperpurulent Conjunctivitis Causative Agent
- Neisseria gonorrhoeae can cause hyperpurulent conjunctivitis, rapidly invading the cornea.
Bacterial Cell Wall Inhibition
- Bacitracin inhibits bacterial cell wall synthesis by interfering with the movement of peptidoglycan precursors.
Transpeptidase Inhibition
- Penicillin acts by inhibiting transpeptidases, enzymes responsible for peptide cross-linkages in bacterial cell walls.
Cationic Detergents in Bactericidal Activity
- Polymyxin B is classified as a cationic detergent that disrupts bacterial cell membrane integrity through surfactant action.
Killing Mechanism of Polymyxin B
- Polymyxin B kills bacteria by disrupting osmotic integrity, leading to cell lysis.
