Abstrakt: Background: Chronic pruritus poses a significant challenge to treating physicians due to multitude of underlying causes and varying treatment strategies. Several topical, systemic, and physical modalities have been tried with variable success. Prescription practices in chronic pruritus are influenced by differential knowledge and experience of physicians, patient-related factors, and resource availability.
Aim: The purpose of this survey was to observe the current pattern of practice in Indian dermatologists in the management of chronic pruritus and to identify practice gaps particularly regarding the use of various systemic agents as antipruritics.
Materials and Methods: A previously validated questionnaire was sent to consultant dermatologists across India between January 2020 and July 2020. The questionnaire was comprised of six questions (multiple-choice questions as well as open-ended questions) regarding the use of antidepressants, cyclic gamma-aminobutyric acid (GABA) analogues, opioid antagonists, antihistamines, and alternate therapies in the management of chronic pruritus.
Results: A total of 700 dermatologists completed the questionnaire (response rate 70%). Overall, antihistamines were the most common drug prescribed in chronic pruritus (more than 95% respondents). Other systemic agents such as opioid antagonists, gabapentinoids, and antidepressants were prescribed by 22.42%, 71.85%, and 75.29% respondents, respectively, in chronic pruritus as either monotherapy or in combination with antihistamines in specific types of itches. Among antidepressants, tricyclic antidepressants (TCAs) (69.29%) were prescribed most often, followed by selective serotonin reuptake inhibitors (SSRIs) (32.29%) and serotonin and norepinephrine reuptake inhibitors (SNRIs) (9.14%). Other treatment options such as omalizumab, thalidomide, ondansetron, ursodeoxycholic acid (UDCA), and rifampicin were used by 10% respondents to alleviate pruritus in special situations.
Conclusion: This survey revealed the redundant practice of prescribing antihistamines in chronic pruritus irrespective of etiology among Indian dermatologists. It also revealed a differential approach regarding use of systemic agents such as gabapentinoids, opioid antagonists, and antidepressants, in academic and non-academic institutions. The survey emphasized a barrier in writing prescription of systemic agents such as opioid antagonist and SNRIs due to lack of knowledge and experience, fear of side effects, and inadequate available evidence.
