Evaluation of PHR160 Spray Effect on Improvement of Lung Function, Asthma Severity and Exacerbation in Severe Asthmatic Patients

Abstract

Pinen Hydronoplacton Ribonucleic acid (PHR160) medicine contains compounds that can be useful in the recovery of respiratory patients. The aim of this study was to determine the effect of PHR spray on improving lung function, severity and asthma attacks in patients with severe asthma. This study is a pioneering interventional study (pilot study) conducted during the years 2021-2022 on patients with severe asthma resistant to treatment who referred to the lung clinic of Imam Khomeini, Golestan Hospitals and the private practice of lung specialists of this academic center. The study includes two groups of patients with asthma, both groups were given the usual treatment according to the stage of the disease, in addition, the intervention group was given two puffs of PHR spray every eight hours, and the control group was given a placebo spray with the same dose. Before and after the intervention, GSK 2002 questionnaire, six-minute walk distance (6MWD) and spirometry tests were completed. Among of 60 patients, 27 (45%) were male. The mean age of the patients was 44.33±6.94 years. Based on findings, the forced vital capacity (FVC) and forced expiratory flow between 25% and 75% (FEF 25-75%) were significantly better in the intervention group than the control group (P<0.001 and P=0.019, respectively), but there was a statistically remarkable difference between the two groups in terms of forced expiratory volume (FEV1) and FEV1/FVC (P=0.505, P=0.575, respectively). In addition, the GSK questionnaire score in the intervention group was higher than the control group (P<0.001), however there is no significant difference between the two intervention groups in terms of the 6MWD test and the number of exacerbation (P=0.114 and P=0.09, respectively). It is generally concluded that PHR160 spray can lead to improvement of spirometry parameters and severity of disease in severe asthma patients by affecting small airways.
