Asthma bronchiale COPD Pharmaceutical care Timeline: 1. Asthma bronchiale (AB) 2. COPD (Chronic obstructive pulmonary disease) • Case reports • Etiology, symptoms, therapy, AB / COPD differences • Inhalation systems - types, theory, images • Inhalation systems - practical demonstrations, training CASE REPORTS 1. Case report – ASTHMA Patient: Kateřina, year of birth 1983 Personal history: bronchial asthma, non-smoker, not allergic to any drugs/medicines, she does not perform self-monitoring of asthma Previously used only inhalation salbutamol, she has worsening of the problem, salbutamol had to be used up to 6 times a week, started waking up at night once a week because of dyspnea (shortness of breath) attacks. That's why her treatment was changed today. Kateřina • Medical history: – Miflonid 400 inh. plv. 1-0-1 – Ventolin Inhaler N 1 to 2 breaths when needed Prescription analysis Miflonid 400 inh. plv. • 1-0-1 • active substance: budesonide • corticosteroid anti-inflammatory agent, high first pass effect of drug residues after absorption (local effect) • Mechanism of action: Reduction of cytokines that activate eosinophils, inhibition of induction of COX-2 inhibits the formation of vasodilating PGE2, PGI2 and spasmogenic leukotrienes, thus reducing the migration of inflammatory elements into the bronchial tissue Prescription analysis Ventolin inhaller N • 1 to 2 breaths when needed • active substance: salbutamol • Beta β2 sympathomimetic, short-acting (SABA), Dosage: • acute therapy: 100-200 μg (1-2 breaths) No more than 8 breaths per 24 hours (800μg), 4 times a day • chronic therapy: up to 200 μg 4 times a day, each 6 hours • the onset of action is within 5-10 minutes, duration of effect up to 6 hours • Dosage only when needed !! salbutamol had to be used up to 6 times a week, started waking up at night once a week Adverse reactions: (Miflonid) - especially oropharyngeal candidiasis (candidosis) to take before a meal and then rinse mouth with water ... and spit out - not to get a systemic effect • Hoarseness (chrapot), dry mouth, reddening in the throat, pharyngeal irritation Self-monitoring AB • By measuring the PEF (peak expiratory flow), by expirometer, monitoring asthma symptoms, • especially when introducing a new drug • PEF values ​​are recorded daily • For our patient, self-monitoring can be recommended due to the newly introduced drug 2. Case report - COPD • Patient: Martin, year of birth 1958 • Laboratory values: blood pressure 130/84, pulse 102, now temperature 37.8˚C • Personal history: COPD, arterial hypertension, hypercholesterolaemia; indicates that he smoked 25 cigarettes a day (since his 18 years of age), currently smokes 10-15 cigarettes a day • He says: he's cold, he starts coughing more often, coughing at night. Medical history • Spiriva 1 – 0 – 0 • Ventolin Every 4-6 hours as needed 1 breath • Indap 2,5mg 1 – 0 – 0 • Sortis 10mg 0 – 0 – 1 Medical history: Spiriva 1-0-0 - S: Tiotropium bromide, anticholinergic- bronchodilators; MA: selective antagonism of cholinergic M3 receptors prevention of bronchoconstriction → D: ok - inhalation once a day at the same time of day Ventolin (every 4-6 hours as needed) - S: Salbutamol IS: bronchodilators, antiasthmatic, betasympatomimetic MA: agonist activity on β2 receptors - induction of bronchodilation → D: ok - inhalation in an acute case Indap 2.5mg 1-0-0 S: Indapamide; IS: antihypertensive, diuretic MI: inhibition of transport Na + / Cl- in the distal renal tubule → D: ok: once a day in the morning (hypertension controlled) Sortis 10mg 0-0-1 - S: Atorvastatin; IS: hypolipidemic MU: inhibition of HMG-CoA reductase inhibition of cholesterol synthesis → D: ok - once a day, regardless of the time of day and food intake Differences from AB treatment • In the treatment of COPD, anticholinergics, β2 agonists, methylxanthines, inhaled corticosteroids, mucolytics, ATBs are used • Habit-breaking is important for smokers! • in the treatment of AB: • immunoprophylatics, anti-leukotrienes, H1-receptor antagonists (allergies) are used Acute exacerbation of COPD Basic Clinical Symptoms: • worsening of dyspnoea • sputum increase • the purulent character of sputum Additional clinical signs: • High temperature, fatigue (weariness) • chest pain, chest tightness • hemoptysis • fluid retention • Cold / or exacerbation? can hardly be recognized !! Therapy of acute exacerbation • Increased dose or frequency of bronchodilators administered • Bronchodilator inhalation: anticholinergics, beta 2 agonists (inh.), Methylxanthines • Systemic Corticosteroids: Prednisone, Prednisolone, Hydrocortisone • Antibiotics in symptomatic infections • Mucolytics • Oxygen therapy - monitoring of respiratory insufficiency • Healing bronchoscopy - suction of mucous plugs • Ventilation support, treatment of associated diseases Therapy of cold, elevated temperature and cough • Antitussics are contraindicated in COPD! (cough has a protective role in COPD) • neopioid analgesics (paracetamol) for colds and elevated temperature. • For cough - expectorancia (erdostein, ambroxol, bromhexin, N-acetylcysteine) • KI NSAID If we suspect acute COPD exacerbation, we will send to the doctor !!! To facilitate coughing, we recommend a suitable mucolytic agent Worsening can be caused by bacterial, viral infections or other factors whose diagnosis and causal treatment belongs to the doctor's hands! Erdostein – No.1 • a muco-modulating agent that acts through its active metabolites • The metabolites in the structure contain two bound sulfhydryl groups that are released in hepatic biotransformation and attack disulfide bridges that bind to each other glycoprotein fibers of bronchial secretion • increases the fluidity of the mucus and facilitates its expectoration from the upper and lower respiratory tract. • a mucolytic agent with antioxidant action and the ability to influence the rheological properties of mucus • an ancillary drug in the therapy of respiratory diseases with mucus formation or expectoration, acute and chronic bronchitis and chronic obstructive pulmonary disease (COPD) Cigarette cessation/substitution therapy OTC medicines with nicotine: NiQuitin, Nicorette ... etc. • in the form of chewing gums, lozenges (pastilles), patches, sublingual tablets, inhalers ADR: tachycardia, hypertension, dry mouth, nausea Drugs – prescription needed- do not contain nicotine: Bupropion (Zyban, Wellbutrin, Elontril) • selective inhibitor of neuronal reuptake of catecholamines (noradrenaline and dopamine) released by nicotine • supression of craving and withdrawal symptoms Vareniclin (Champix) • partial nicotinic receptor agonist • Risk of suicide? …. Cigarette cessation/habit-breaking therapy THEORY AB/COPD 1. Asthma bronchiale • Worldwide incidence of 1-18% of the population (unknown in the Czech Republic, children 8%) • Chronic inflammatory disease of the respiratory tract • Bronchial hyperreactivity • Complete / partially reversible airway obstruction = asthmatic attacks/episodes • mediators of inflammation are produced that increase the bronchial reactivity (eosinophils) • Most patients compensated by therapy • severe acute condition lasting several hours to days = status asthmaticus Triggering factors Allergens Infections (viruses) Environment Changes of the weather Physical activity Food Emotions Etiopathogenesis od AB Inflammation Activation of mast cells, macrophages eosinophils Release of mediators of inflammati on Histamin, PG, LT, bradykinin Bronchoconstric tion, mucus secretion, plasma exudate, bronchial hyperreactivity, DC change structure Predisposition to Asthma • A necessary combination of genetic predisposition and external influences • Polygenic heredity • Low birth weight • Mother - a smoker • Infection in childhood • Atopic terrain (x COPD) Division of AB by intensity / difficulty Asthma - therapy Indicator Asthma under control Asthma under partial control Asthma under insufficient control Symptoms during the day no more often than twice a week three or more indicators under partial control Restriction of activities no any Night symptoms, awakening no any Need for Relief Medication no more often than twice a week Pulmonary function (PEF, FEV1) no < 80 % Exacerbace no 1 or more / year one at a time Clinical manifestations of asthma • Cough (unproductive) (x COPD) • Dyspnoea (night,early morning) • Chest pressure • Wheezing during breathing • Prodromal symptoms before attack (itchy under the chin, anxiety) • Symptoms disappear after administration of β2-mimetics (dg .)

COPD • One of the most common causes of death • The incidence is about 7.7%, in the Czech Republic it is 700 - 800 thousand patients • !!!!! Smoking (20-25% of smokers will have COPD) • Environmental pollution (Si, Cd, oxidants ... bricks production, asbestos production, coal mines) • Infections (repeated in childhood ... most commonly viral) • nutrition, poverty • increased inflammatory response to risk factors • restricting airflow in the bronchi (bronchial obstruction) that is not completely reversible • imbalance between proteases and antiproteases in lungs pulmonary emphysema Symptoms • Chronic bronchitis • Long-term mucus expectoration (morning coughing) • Dyspnoea with a tendency to progression • Limitation of ability to increase physical activity • stadium III, IV. - cachexia, muscular atrophy • Dg: Forced expiratory volume (FEV1) - incomplete obstruction reversibility • Depending on the severity of the symptoms of stages GOLD I to IV Therapy • Regular aerobic physical activity - rehabilitation • Removal of chemicals • Smoking cessation, habit-breaking • Vaccination against influenza, pneumococcus = prevention of infection Pharmacotherapy - symptomatic • Oxygen - Long-term Home Oxygen Therapy • Surgery - bulectomy (removal of bullous emphysema, lung transplantation) • Causal COPD therapy does not exist Therapy • Long-term beta2mimetics from II. stage • formoterol, salmeterol (Twice a day) • indacaterol (Onbrez) (once a day) referred to as ULABA • olodaterol • Long-acting anticholinergics (LAMA) from II. stage • tiotropium (Spiriva) – improvement of VC of lungs, static functions – increasing tolerance of effort • aclidinium (Bretaris, Brimica komb.) • umeclidinium (Incruse, Anoro komb.) • glycopyrronium (Seebri, Ultibro komb) • Inhalation corticosteroids from III. stage • Long-term p.o. the theophylline derivatives (drugs of 3rd line..)

ICS General principles of correct inhalation (2) Candidiasis (IKS): • characteristic white coating that is painful and burning blisters may develop, • Occurrence: skin, mucous membrane • Local therapy (rinses - nystatin, clotrimazole) • Systemic therapy (ketoconazole, fluconazole, itraconazole) 1. Inhalers (MDI, metered dose inhalers) • Liquid vehicle • Freons are replaced by hydrofluoroalkane (HFA) – do not cause local mucus cooling • Shake before use • It is necessary to synchronize the breath (inhalation) with the pressing the inhaler • Patients (children) can use spacer, aerochamber • "N" water base, no need to shake • Ventolin N, Ecobec, Ecosal • Berodual N How do I know the empty pressure vessel at the inhaler? a) Dosing aerosol + Spacer Spacer is an inhalation extension that increases the effect of the metered aerosol because: • increases the amount of medicine that gets into your lungs • reduces the amount of drug stored in the mouth • co-ordination of breath and pressing is not required Disadvantages of the inhalation adapter: • is too big • necessary regular cleaning b) Inhalation extension with mask (aerochamber) Procedure: • Remove the cap, shake the inhaler, and insert it into the extension. • Put the mask on your face so that it covers your mouth and nose. • Breathing from the extension must be slow and quiet. • Press the dispenser container once and inhal several times and exhale. • Remove the attachment from the face. If you are taking another dose, • wait for at least 30 seconds. b) Aerochamber 2. Easi-breathe (BAI, breath-actuated inhalers) • The dose is released by inhaled air • Automatic application • eliminate the issue of hand-inhalation coordination, respectively handbrain coordination • Sufficient FEV1 is required (forced expiratory volume in 1 second) • Ecosal Easi-Breathe • Beclazone Easi-Breathe 3. Turbuhaler (DPI, dry powder inhalers) • Active substance in powder form • It is released from the container after turning • small inspiration (inspirium) needed • Pulmicort Turbuhaler, Symbicort Turbuhaler, Bricanyl Turbuhaler 4. Easyhaler • Applied substance in powder form • Simple operation • Shake before use • Dose release after pressing the dispenser • It is possible to inhale the dose several times • Buventol Easyhaler, Giona ... • Formoterol Easyhaler • Beclomet Easyhaler 5. Diskus • Less number of doses (60-28) • Doses pre-prepared in a blister (powder form) – compact shape – dry, never breathe in – dose counter to zero (last 5 red) Seretide Diskus, Flixotide Diskus 6. Aerolizer (spinhaler) • Patient inserts capsules filled with a dose of the drug • Spines in the applicator will disrupt the packaging and allow the inhalation of the powder • It is necessary to manipulate with each dose • Miflonid, Foradil • Onbrez, Seebri (Breezhaler) applicator included in the package • Spiriva (HandiHaler) applicator extra Aerolizer (spinhaler) Remove the applicator cover Hold the applicator base firmly and turn the mouthpiece Remove the capsule from the blister and put it in the basement Turn the mouthpiece back against direction of the arrow until it fits with a clear click Press both brown buttons. The capsule i opened. Take a deep breath, close your lips and inhale deeply. 7. Respimat • SMI - soft mist inhaler • The drug solution is transferred to the mist in the applicator head • Inhalation of mist formed • Synchronization with breath needed • Two doses should always be inhaled Spiriva Respimat, Spiolto respimat (tioptropium + olodaterol) New powder inhalers Genuair Bretaris (aclidinium bromid) • Powder for inhalation Genuair Bretaris (aclidinium bromid) • Powder for inhalation Ellipta (GSK) Ellipta (GSK) Relvar, Revinity, Anoro, Leventair, Incruse vilanterol, umeclidinium… Spiromax (Teva) Duoresp 160/320 (budesonid /formoterol) Forspiro (Sandoz) Airflusan (salmeterol/fluticason) Cleaning of applicators • Different depending on the type of construction • Remove everything you can • Rinse with lukewarm or hot water • Let it dry in the air • Dry by the hair dryer • Do not dry with a dry cloth - static electricity is generated but dry powder forms, e.g. Easyhaler • Clean mouthpiece at least once a week with dry cloth, do not use water, Easyhaler powder is sensitive to moisture • If the inhaler is accidentally pushed or pushed more than once, remove the powder from the mouthpiece by tapping against the table or palm Cases % He does not understand the instructions for use 33, 0 % He thinks another dose is better for him 24, 8 % He thinks another drug is better for him 13, 3 % He thinks he's already cured 10, 5 % He forgot to use the medicine 5, 7 % He thinks the cause of his illness is a cure 4,7 % He feels resistance to the drug 3, 8 % He thinks the medicine damages him at work 1, 0 % The patient has lost or is physically unavailable 1, 0 % Various other causes 2, 2 % Non-compliance of patients with AB - the role of pharmacist „Ten Commandments“ of asthma treatment (dle MUDr. Milan Teřl,PhD., FN Plzeň) 1. Each asthma patient should be informed about the chronic course of the disease and know the difference between the preventive and maintenance medication 2. Each should be equipped with both types of prevention and relief 3. Whenever possible, the inhalation form is preferred 4. Effect of preventive drugs is not immediate 5. The relief medication should be used exceptionally - except SMART (Single Maintenance and Reliever Therapy) - fixed combination 6. Type of drug to choose by type of patient - skill, age, vision, experience, intelligence, socio-economic status 7. All inhalation drugs should preferably be in the same or similar system 8. Prescription = presentation of the inhalation technique, dispensing in the pharmacy = verbal instructions 9. Do not drop off tretament/drugs without consulting your doctor (even during pregnancy) 10. Compliance and inhalation monitoring regularly
