Local Anesthetics: Clinical Application as Epidural Anesthesia

926
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Summary

The intracanalicular dexamethasone insert (DEX) offers a novel approach to managing post-operative ocular pain and inflammation. This resorbable hydrogel insert provides sustained drug delivery, overcoming limitations of traditional topical therapies for ophthalmic surgery patients.

Area of Science:

  • Ophthalmology
  • Pharmacology
  • Drug Delivery Systems

Background:

  • Ophthalmic surgery frequently leads to transient pain and ocular inflammation, impacting patient satisfaction and visual outcomes.
  • Topical anti-inflammatory drops, while effective, present challenges like poor adherence and side effects (e.g., cataracts, elevated intraocular pressure).
  • A significant unmet need exists for improved therapies that combine anti-inflammatory and analgesic properties while mitigating topical treatment drawbacks.

Purpose of the Study:

  • To review the therapeutic landscape for managing postoperative pain and inflammation after ophthalmic procedures.
  • To evaluate the efficacy and limitations of the intracanalicular dexamethasone insert (DEX) as an alternative to topical therapies.
  • To summarize clinical trial data and literature supporting DEX for various ophthalmic conditions.

Main Methods:

  • Comprehensive literature review of current therapeutic strategies for postoperative ocular pain and inflammation.
  • Analysis of Phase 2 and 3 clinical trial data supporting DEX approval and label expansions.
  • Summary of studies investigating DEX for ophthalmic surgeries beyond cataract surgery and allergic conjunctivitis.

Main Results:

  • The intracanalicular dexamethasone insert (DEX) is a resorbable hydrogel delivering 0.4 mg of preservative-free dexamethasone over ~30 days.
  • DEX has received FDA approval for treating pain (2018) and inflammation (2019) post-ocular surgery, and ocular itching (2021).
  • Clinical data supports DEX's role in managing pain and inflammation across various ophthalmic surgeries and allergic conjunctivitis.

Conclusions:

  • The intracanalicular dexamethasone insert (DEX) presents a viable alternative to topical eye drops for managing ocular pain and inflammation.
  • DEX's sustained-release mechanism and resorbable nature address key limitations of conventional treatments.
  • Further research and application of DEX show promise for improving patient outcomes in ophthalmology.
