Study Notes
Ear Disorders
- Otitis externa (external otitis): Inflammation of the outer ear, often associated with water exposure (swimmer's ear).
- Otitis media (middle ear infection): Inflammation of the middle ear, often associated with upper respiratory infections, allergies, or auditory tube dysfunction.
- Impacted cerumen (earwax): A blockage of the ear canal by earwax.
- Otic administration: Used to treat ear conditions, including infections and ear canal blockages.
-
Otic drug types:
- Anti-infectives: Treat ear infections. Common examples include amoxicillin, azithromycin, clarithromycin, neomycin, polymyxin B, hydrocortisone, chloramphenicol, and fluoroquinolones.
- Cerumenolytics: Soften earwax for easier removal.
-
Ear drop application:
- Adults and older children: Pull ear back and up.
- Children under 3: Pull ear down and back.
- Ear drops for middle ear infections: May cause allergic reactions, leading to hives.
- Severe ear infections: Often require systemic (oral or intravenous) antibiotics in addition to ear drops.
Eye Disorders
-
Glaucoma drops: Used to lower intraocular pressure (IOP) and prevent optic nerve damage.
- Cycloplegics: Paralyze eye muscles, dilate the pupil, and allow for procedures like cataract surgery.
- Mydriatics: Dilate the pupil for better visualization of the eye's internal structures.
- Prostaglandin analogues: Reduce IOP by decreasing fluid production.
- Beta-adrenergic blockers: Decrease IOP by reducing aqueous humor production (medications ending in “-olol”).
- Glaucoma pharmacotherapy: Often requires combination therapy to achieve desired IOP reduction.
- Nasal administration: Used for both local and systemic effects.
-
Nasal decongestants:
- Actions: Constrict blood vessels, shrinking swollen nasal membranes.
- Use: Limited to 3-5 days due to rebound congestion.
- Forms: Over-the-counter sprays and drops.
-
Nasal corticosteroids:
- Actions: Suppress the immune/inflammatory response.
- Use: Not for long-term use. Take several weeks for full effectiveness. Best to use before the peak allergy season.
