Pharmacotherapy of Demodex-Associated Blepharitis: Current Trends and Future Perspectives

Demodex-associated blepharitis (DAB) is a common condition in our society. Patients report not only uncomfortable and bothersome symptoms but also decreased self-esteem and confidence. Because of its nonspecific signs, pharmacists are often the first healthcare professionals patients consult. What is most concerning is that DAB can cause serious complications within the eye, such as dry eye syndrome, corneal scarring, or recurrent styes and chalazia. Therefore, we aimed to compile both standard and innovative therapies and compare their effectiveness and safety. As shown, standard methods remain the recommended approach. Alongside antiparasitic agents such as metronidazole or ivermectin, education and improved eyelid hygiene are crucial. However, in recent years, promising new treatments for Demodex blepharitis have emerged, such as Lotilaner Ophthalmic Solution 0.25%, which has shown positive results in clinical trials. Mechanical techniques, including Intense Pulsed Light (IPL) therapy and eyelid peeling procedures such as Blepharoexfoliation, have also demonstrated promise. Due to the notable effects of tea tree oil, studies have explored the lethal effects of other essential oils, such as sage, peppermint, and bergamot oils. These are just a few of the interesting examples discussed in this paper.
