Abstract

     

Metered Door Inhaler and Dry powder inhaler are both used to treat the symptoms, such as: wheezing, coughs etc. of pulmonary disease in a Patient. The main objective of this study is to find out the comparative analysis of pMDI & DPI in asthma medication at rural area of Bangladesh. A cross sectional study including survey and interview was completed at in the outpatients department (OPD) of Patuakhali 250 Bed Sadar Hospital, Patuakhali. The sample was 120 Asthma patients studied over a period of six months from January 2019 to July 2019. The measurements of FEV1 & VC demonstrate airflow obstruction and following the administration of a bronchodilator, confirm the diagnosis when a 15% (and 200ml) improvement in FEV1 is noted. Subsequent follow-up were done by Peak Flow Meter. Medications were used as single maintenance & reliever therapy using Budesonide (ICS) & Formeterol (LABA). Devices that were used for the study are Pressurized Metered Dose Inhaler (pMDI) and Dry Powder inhaler (DPI) eg: Aerolizer. Proper inhalation techniques of the inhaler were demonstrated to the patients by the health care staffs from the hospital.

 pMDI and DPI (Aerolozer) have no significant differences in compliance issue in patient’s points of view in terms of rural Bangladesh perspective. DPIs are flow dependent and require minimal patient to device co-ordination. pMDI requires patient to device co-ordination.
