3 COPD, or C hronic O bstructive P ulmonary D isease, is a progressive disease that makes it hard to breathe . Definition (GOLD-2020) GOLD ( G lobal Initiative for Chronic O bstructive L ung D isease) has defined COPD as a common , preventable and treatable disease that is characterized by - Persistent Respiratory Symptoms Due to airway and/or alveolar abnormalities usually caused by significant exposure to noxious particles or gases Airflow limitation (many factors cause this airflow limitation) GOLD-2020

6 Causes/Risk Factors for COPD Smoking is the largest contributor to the COPD burden [SDI=69.4] in developed countries. However, COPD burden [SDI=58.1] due to environmental exposures is highest in developing countries 80% of COPD in India is due to non-smoking (only 20% cases are smoking). Out of 80% COPD cases, 35% are because of household pollution ( BIOMASS ) 35% are because of air pollution outside 10% are because of occupational exposure . [ rediff article 2018; GBD data 2016]

8 Why use bronchodilator therapy in COPD? Lancet Respir Med. 2017 Jul;5(7):540-542 COPD Cause Symptoms Persistent Airflow Limitation is the principle pathology of COPD ! Caused by multiple factors, 1. Bronchoconstriction 2. Mucus hypersecretion 3. Airway remodelling 4. Reduced elastic recoil & alveolar attachments - Emphysema Bronchodilator therapy is the cornerstone in COPD Management Bronchodilators work by relaxing the smooth muscles around the airways allowing them to dilate & become larger to facilitate easier breathing Relieves the trapped air. Provides Symptomatic Relief Inflammation, Oxidative stress and Protease
Reflex Cholinergic tone Appears to be major reversible component of airways Obstruction In COPD Eur Respir Rev 2006; 15: 99, 32–36 9 Drug of Choice Inhaled Anti Cholinergic Agents
10 Why to use Glycopyrrolate as a bronchodilator in COPD Management Lately, various clinical trails have shown that – Glycopyrrolate, a long acting muscarinic antagonists [LAMA] DEFLATES the lungs, Glycopyrrolate binds to M3 muscarinic receptors & produces prolonged bronchodilation. Expert Rev Respir Med. 2018 Jun;12(6):447-459 Reduces breathlessness, Reduces exacerbation risk & improves quality of life in moderate to severe COPD patients . Deflation Air flow
11 Following an acute exacerbation, what are the majority of your COPD patients prescribed at discharge? LABA + LAMA ICS + LABA ICS + LABA + LAMA
12 What influences your drug prescription for AECOPD patients post discharge?
Which device is prescribed at discharge to the majority of patients post acute exacerbation of COPD? 13 pMDI with Spacer DPI BAI Nebulizer

Selecting Inhalation Device should be Based on Quality Of Actuation-inhalation Coordination & PIFR ERS Annual Congress London 2016 15 It is also recommended that patient preferences for devices should be considered when prescribing an inhaler, but physicians must be cognizant that patients often overestimate their ability to handle a device correctly
<10% 10-20% 21-30% 31-40% >40% Don’t know In your opinion, what percentage of your AE-COPD patients would have a low PIFR (<60L/min)
17 Important message: PIFR is reduced even in stable COPD patients (in outpatient settings) Discordance with prescribed inhalers was seen in 40% of COPD patients , suggesting that many COPD patients do not generate required inspiratory force to overcome prescribed DPIs resistance in the course of normal use. 2019
18 Should PIFR be checked for both in- and outpatients for assessing suitability of delivery devices including nebulized therapies? Yes No
Role of nebulizers as an alternative in the long-term management of COPD at home
20 In your opinion, what are the factors that determine the selection of COPD patients for home maintenance nebulization? Patients must be carefully screened before prescription of maintenance nebulization. More importantly, the screening should focus on the ability to use handheld inhaler devices and every effort should be made to introduce/re-introduce drug administration through handheld inhalers J Assoc Physicians India. 2017 May;65(5):60-73
21 Clinical Scenarios where Maintenance Therapy with Nebulizer is Preferred in Patients with COPD Patients with inspiratory flow rates as low as 30 L/min Patients who are unwilling or find it difficult to use pMDI or DPI Patients having breath hold capacity of < 5-10 sec Patients who have cognitive impairment, muscle weakness due to age or co-morbidity COPD. 2012 Feb;9(1):58-72, J Allergy Clin Immunol Pract . 2018 May - Jun;6(3):987-995 Patients with poor hand-eye coordination

The term "night-time symptoms" in COPD has not been distinctly defined in an objective sense but epidemiological data suggests that the prevalence of nocturnal symptoms and symptomatic sleep disturbance may exceed 75% in patients with COPD . The panel concluded that Night-time symptoms in COPD are prevalent and bothersome; their cause(s) are multiple and include demographic factors, such as age and obesity, pharmacotherapy, disease-specific symptoms and the presence of comorbid sleep disorders, and other medical conditions; potential long-term consequences can include lung function changes, increased exacerbation frequency, emergence or worsening of cardiovascular disease, cognitive effects, depression, impaired quality of life and increased mortality.

46 On what aspects of nebulization do you think the patients should be educated?
Advise patients to have their full supply of medication at home 1 Perform nebulization in a well ventilated room Prevent your caretaker/family member from staying inside the room during nebulization DON’T let the caretaker get too close while Nebulization is being conducted. Maintain distance of at least 6 feet from the patient . Close the door while nebulization is being undertaken. 2 DON’T share nebulizers between family members . Every nebulizer should be a single-use nebulizer 2 . Avoid air-conditioning in the room altogether 5 . DO leave the room vacant with the door closed for 30 minutes after the patient has vacated the room post-nebulization. 4 Wash the accessories as per the guide and use disinfectants like Isopropanol (70%) or Hydrogen Peroxide (3%) 4. 1 WHO Interim guidelines 2019; 2 CDC guidelines www.health.state.mn.us ; 3 https://www.cdc.gov/coronavirus/2019-ncov/hcp/hand-hygiene.html ; 4 https://www.health.qld.gov.au/data/assets/pdf_file/0038/939656/qh-covid-19-Infection-control-guidelines.pdf ; 5 www.ncdc.gov Good Nebulization Practice at HOME Setting
48 All inhalation devices are equally efficacious in all types of patients provided they are used correctly Not all patients can use handheld inhalers. Hence Nebulization can be an alternative treatment modality Patients on maintenance nebulization should undergo regular review to ascertain long-term safety Selection of an appropriate inhalation device should have individualized and patient-specific approach Patients should strictly follow cleaning and maintenance recommendations Take Home Points to Remember
