Ophthalmic Drug Delivery Systems

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...

Summary
This summary is machine-generated.

Ophthalmology self-medication is common, with 37.2% using prescription eye drops like steroids. Many users are unaware of serious steroid-related ocular complications, increasing risks.

Area of Science:

  • Ophthalmology
  • Public Health

Background:

  • Self-medication with ophthalmic drugs is a growing concern globally.
  • Limited data exists on self-medication patterns and awareness of side effects in Saudi Arabia.

Purpose of the Study:

  • To investigate the prevalence of self-medication practices in ophthalmology within the Riyadh region.
  • To assess awareness of potential side effects associated with commonly used ophthalmic medications.

Main Methods:

  • An electronic, cross-sectional, descriptive survey was conducted.
  • 1354 participants from the Riyadh regional population were included in the study.

Main Results:

  • 37.2% of participants reported self-medicating with prescription eye drops (topical antibiotics and steroids).
  • Steroid-containing eye drops were the most frequently used after lubricants (32.6%).
  • A significant majority (86.6%) of steroid users were unaware of steroid-related ocular complications.

Conclusions:

  • High rates of self-medication with ophthalmic drugs, particularly steroids, were observed.
  • A concerning lack of awareness regarding the side effects of topical ophthalmic medications exists.
  • This combination of high self-medication and low awareness poses a risk for preventable adverse ocular events.
