Ophthalmic Drug Delivery Systems01:23

Ophthalmic Drug Delivery Systems

283
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...

Open Angle Glaucoma: Treatment

1.1K
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Angle Closure Glaucoma: Treatment

1.6K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Area of Science:

  • Ophthalmology
  • Pharmacology

Background:

  • Dry eye syndrome is a multifactorial ocular surface disease characterized by reduced tear quantity and sensitivity, leading to inflammation.
  • Current treatments include artificial tears, tear retention, tear secretion stimulation, and anti-inflammatory drugs.

Purpose of the Study:

  • To review novel and future pharmaceutical compounds for dry eye disease treatment.
  • To identify emerging therapeutic strategies targeting key inflammatory pathways.

Main Methods:

  • Literature and patent review of pharmaceutical compounds for dry eye disease.
  • Analysis of compounds targeting inflammatory pathways and tear film restoration.

Main Results:

  • Secretagogues and anti-inflammatory drugs are the most frequent categories of novel compounds.
  • These compounds represent new therapeutic strategies for dry eye disease.

Conclusions:

  • Novel pharmaceutical compounds show promise in managing dry eye disease.
  • Future treatments focus on reducing inflammation and restoring ocular surface health.
