Impact of topical 5% lidocaine-medicated plasters on sleep and quality of life in patients with post herpetic neuralgia
Key Take-Away: 

Lidocaine is tropically used to relieve pain. The overall benefits of lidocaine- medicated plasters were drawn out from this research article with the help of study based on a pain questionnaire.

To determine the impact of 5% lidocaine-medicated plasters on sleep, quality of life and pain in 265 patients with post herpetic neuralgia (PHN).

ABSTRACT: 
Background: 

To determine the impact of 5% lidocaine-medicated plasters on sleep, quality of life and pain in 265 patients with post herpetic neuralgia (PHN).

Methods: 

An 8-week, open-label arm of a double-blind controlled withdrawal study.

Results: 

Patients treated with 5% lidocaine had less trouble falling asleep, used less sleep medication, had fewer awakenings due to pain at night or in the morning and their perception of quality of life was improved.

The 15 pain descriptors in the Short-Form McGill Pain Questionnaire were improved from baseline to week 8, with a decrease in the proportion of patients reporting ‘severe’ pain and an increase in the number reporting ‘none/mild’ pain.

Conclusion: 

5% lidocaine-medicated plasters provide benefits beyond pain relief for patients with post herpetic neuralgia.
