Postherpetic Neuralgia (PHN) is an inflammatory neuropathic pain condition characterized by pain persisting for more than 30 days after the onset of the herpes zoster rash caused by a byproduct of varicella zoster virus reactivation. Symptoms include dysethesia, spontaneous burning pain; shooting, tic-like pain. PHN treatment guidelines recommend antiepileptic drugs (namely, Lyrica and gabapentin), followed by tricyclic antidepressants (e.g., amitriptyline), and topical lidocaine patches (e.g., the 5% lidocaine patch). Given the substantial percentage of patients with inadequate pain relief, together it is important to understand use of current therapies in newly diagnosed and recently treated PHN patients thought the use of national patient-level claims data.
- What patient share do key therapies and brands garner by line of therapy in newly diagnosed PHN patients?
- What are the quarterly trends in prescribing among recently treated and new diagnosed PHN patients?
- How have Lyrica, gabapentin, the 5% lidocaine patch, and Qutenza been integrated into the treatment algorithm?
- What proportion of PHN patients receive drug therapy within a year of diagnosis, and how quickly?
- What percentage of patients progress to later lines of therapy within a year of diagnosis?
- What percentage of PHN patients are treated with monotherapy versus combination therapy?
- What are the most widely used combination therapies? · What are the product-level compliance and persistency rates among drug-treated patients with PHN?
