DRUGS USED IN ASTHMA AND OTHER BRONCHODILATORS Prof. Dr. Zeliha Yazıcı REGULATION OF THE AIRWAY Drugs affect the respiratory system in a number of ways Airway smooth muscle tone depends on the balance between the: Parasympathetic input Inhibitory influence of circulating epinephrine NANC inhibitory nerves Sympathetic innervation of the parasympathetic ganglia Efferent pathways o Parasympathetic innervation Airway & vascular smooth muscles, glands M3 rec. bronchial smooth&glands, bronchoconstriction&muc us secretion M1 rec. ganglia&postsynaptic cells, nicotinic neurotransmission M2 rec. inhibitory autoreceptors, negative feedback on ach release o Sympathetic innervation Tracheobronchial blood vessels & glands β2-rec. airway smooth muscle, mast cells, epithelium, glands, alveoli o NANC nerves Inhibitory: VIP, NO; bronchodilation Excitatory: substance P, neurokinin A; neuroinflammation Afferent pathways o Slowly adapting strech rec. control respiration via respiratory center o Rapidly adapting irritant rec. o Unmyelinated sensory C fibres Inhalated irritants: May trigger the release of mediators from mast cells May stimulate afferent receptors to initiate reflex bronchoconstriction or to release tachykinins that directly stimulate smooth muscle contraction ASTHMA Inflammation of the airway Bronchial hyper-reactivity Reversible air way obstruction o Allergic (extrinsic) o Idiosyncratic (intrinsic) Occupational asthma aspirin-induced asthma exercise-induced asthma Exposure to allergen causes synthesis of IgE On reexposure to allergen, antigen-antibody interaction triggers release of mediators of anaphylaxis which cause bronchospasm (Early reaction) Reexposure to allergen causes the synthesis and release of cytokines Cytokines activate eosinophils (ECP, eosinophil cationic protein; MBP, major basic protein) and neutrophils (Proteases, PAF) These mediators cause the edema, smooth muscle contraction, mucus hypersecretion (Late reaction). Bronchial hyperreactivity quantitated by measuring the fall in forced expiratory volume in 1 second (FEV1) Aspirin-sensitive asthma <10% of asthmatic subjects associated with nasal polyps usually sensitive to other chemicals (paracetamol) abnormal LT production & sensitivity directly activate eosinophils and mast cells CHRONIC OBSTRUCTIVE PULMONARY DISEASE Inflammation of the airway with a pattern that differs from that of asthma Neutrophils, macrophages, and cytotoxic Tlymphocytes are predominance Progressive small airway narrowing and fibrosis (chronic obstructive bronchiolitis) Destruction of the lung parenchyma and alveolar walls (emphysema) These pathological changes result in airway closure on expiration, leading to air trapping and hyperinflation particularly on exercise (dynamic hyperinflation) Bronchodilators are mainstay of treatment in COPD Inflammation is largely corticosteroid resistant Patient have systemic manifestation (skeletal muscle wasting, weight loss, depression, osteoporosis, anaemia) and comorbid disease (ischemic heart disease, hypertension, congestive heart failure, diabetes) ROUTES OF DRUG DELİVERY TO THE LUNG Inhaled route ~ 10-20% of drug enters the lower airways Optimum particle size 2-5 μm, ~ 1 μm in COPD and severe asthma o Pressurized metered-dose inhalers o Spacer chambers o Dry powder inhalers o Nebulizers Oral Dose is higher than the inhaled dose Systemic side effects are more common Parenteral Preferred in severely ill patients Systemic side effects are generally frequent DRUGS Bronchodilators β-receptor agonist Antimuscarinics Xanthines (theophylline) LOX inhibitors and cysteinyl lekotriene receptor antagonists Anti-inflammatory agents Glucocorticoids Mast cell stabilizer (Cromolyn, nedocromil) β-receptor agonists β2-selective drugs are the most widely used (non selective sympathomimetics cause more cardiac stimulation) stimulate adenylyl cyclase-cAMP system and relax airway smooth Molecular mechanisms: Lowering Ca+2 concentration by active removal of Ca+2 from the cytosol into intracellular stores and out of cell Acute inhibition of the PLC-IP3 pathway and its mobilization of cellular Ca+2 (prolonged use can upregulate expression of PLCβ1) Inhibition of myosin light chain kinase activation Activation of myosin light chain phosphatase Opening of a large conductance Ca+2 activated K+ channel which repolarizes the smooth muscle cell β2 receptors may couple to KCa via Gs so that smooth muscle relaxation may occur independently of an increase in cAMP Indirect effects of β2-agonists Prevention of mediator release from lung mast cells (via β2-receptor) Prevention of microvascular leakage and thus the development of bronchial mucosal edema after exposure to the mediators Increase in mucus secretion from submucosal glands and ion transport across airway epithelium Reduction in neurotransmission in cholinergic nerves by an action at presynaptic β2-receptors to inhibit ach release Side effects: Skeletal muscle tremor, tachycardia, tolerance, decrease in PaO2 (reduced when inhalers are used), hypokalemia, hypoxemia, death with cardiac arrest in excessive amounts Causes of the tolerance: 1) desensitising of receptors 2) receptor down-regulation 3) decrease in the binding of β2-receptor synthesis coding gene to CREB (cAMP response element binder) 4) induction of PDE Chemical structure Non-selective betamimetics Adrenaline β1 and β2 agonist Bronchodilator and vasoconstrictor For acute asthma attack: 0.25-0.5 mg sc or im; for child: 0.01mg/kg/4 h Side effects: Tachycardia, arrhythmias and worsening of angina pectoris Izoproterenol A potent bronchodilator 80-120 µg causes maximal bronchodilation within 5 mins when inhaled Inhalation (aerosol and solution) Ephedrine (Ephedra equisetina) Has a longer duration, oral activity, more pronounced central effect and much lower potency, compared with adrenaline Selective β2-agonists Albuterol (Salbutamol), metaproterenol, terbutaline Short-acting β2 –selective agonists inhalers and also in tablet form, terbutaline is available for sc injection Side effects: Skeletal muscle tremor, nervousness, occasional weakness Salmeterol, Formoterol Long-acting β2 –selective agonists (12 hrs or more) Salmeterol also binds to an exo-receptor in the vicinity of the β2 –receptor on airway smooth muscle Inhaler Useful for treating nocturnal asthma Interact with inhaleted corticosteroids (bronchial hyperactivity ↓↑, CREB-GR protein-protein complex) They are not recommended as the sole therapy for asthma, should only be used as adjuvant therapy in patient not adequately controlled on inhaled corticosteroids or whose disease require two maintenance therapies. Side effects: Tremor, dizziness, headache, tolerance, an increase in asthma mortality Antimuscarinics They cause bronchodilation by binding to muscarinic receptors on airway smooth muscle Do not prevent all type of bronchospasm Are effective against irritant-induced changes in respiratory function Increase FEV1 Decrease mucus secretion Available muscarinic antagonists do not discriminate between M2 and M3 receptors Atropine causes bronchodilation at a lower dose than that needed to cause an increase in heart rate Ipratropium and oxitropium are used by the inhaled route to reduce systemic adverse effects; poorly absorbed into the circulation; do not cross the blood-brain barrier Their efficacy in asthma is modest compared with in chronic obstructive pulmonary disease (COPD) Xanthines Theophylline Bronchodilator (inhibit phosphodiesterase 3 and 4 and block adenosine A2B receptors) anti-inflammatory (IL-10↑, cytokines↓, release of mediators from mast cell↓) Tolerans dose not develop The major problem is that they have a very narrow therapeutic window Plasma concentration over 10µg/ml are required for effective bronchodilation, but over 20µg/ml are associated with an increased likelihood of adverse effects (nausea, arrhythmias, convulsions) Inhibition of airway smooth muscle relaxation Change in FEV1 Inhibition of phosphodiesterase activity The dose should be adjusted to give a serum concentration of 5-15µg/ml Metabolised by CYP1A2 Factors affecting clearance of Theophylline Increased: barbiturates, ethanol, smoking via CYP1A2 induction, high protein diet, lowcarbohydrate diet, barbecued meat, childhood Decreased: cimetidine, erythromycin, ciprofloxacin, allopurinol via CYP inhibition, congestive heart failure, liver disease, pneumonia, viral infection and vaccination, highcarbohydrate diet, old age Adverse effects: anorexia, nausea, vomiting, abdominal discomfort, headache, anxiety, seizures, arrhytmias, insomnia Aminophylline (theophylline-ethylenediamine complex) Dyphylline (synthetic analog of theophylline) Less potent and shorter acting than theophylline LOX inhibitors and cysteinyl lekotriene receptor antagonists Montelukast LTD4 and LTE4 (cisLT1) receptor inhibitor Metabolised by CYP3A4 Are effective in aspirin-induced asthma and exerciseinduced asthma Orally active Zafirlukast LTD4 and LTE4 (cisLT1) receptor inhibitor Metabolised by CYP3A4 Orally active Zileuton 5-LOX inhibitor Orally active Corticosteroids Broad anti-inflammatory efficacy (inhibit PLA2 activity, the expressions of COX-2, 5-LOX, NO-synthase, and endothelin-1 synthase cytokines) Reduce edema formation potentiate the effects of beta-receptor agonists do not relax airway smooth muscle reduce bronchial reactivity and the frequency of asthma exacerbation increase airway caliber effective in improving all indices of asthma first-line therapy for moderate to severe asthma Urgent treatment: oral 30-60 mg/day prednisone or iv 1 mg/kg/6 hrs methylprednisolone; daily doses is decreased gradually Administered early in the morning after endogenous ACTH secretion has peaked; inhaled corticosteroids (lipidsoluble) are more effective in the late afternoon in nocturnal asthma Lipid-soluble corticosteroids (Beclomethasone, Fluticasone, Budesonide, mometasone, flunisolide, triamcinolone) are relatively safe.

She reported having had asthma since childhood, with a period of frequent childhood hospitalization. Typical asthma symptoms had reappeared when she was in her late twenties and persisted. She had been using inhaled salbutamol (albuterol) on an as needed basis for many years and for 8 years had used inhaled fluticasone 250 µg twice daily a week. When stable, she resorted to salbutamol once or twice daily and awoke with asthma symptoms once or twice a week. She avoided aerobic exercise because it typically triggered episodes of wheezing. Exacerbations characterized by increased cough, wheeze, and breathlessness occurred at the rate of one to three episodes a year and typically responded to therapy with a short course of oral prednisone at a dosage of 40 mg daily for 7 days. She was a non-smoker and kept no pets. On assessment in the clinic, her physical examination was unremarkable, with no finding in the chest. However spirometry showed moderate airflow obstruction with a brisk but incomplete response to inhaled bronchodilator. Her metereddose inhaler technique was found to be suboptimal. She was advised to replace inhaled corticosteroid monotherapy with a combination of inhaled fluticasone 500 µg and salbutamol 50 µg to be inhaled via dry powder devise twice daily. At a follow-up visit 3 months later, her nocturnal asthma symptoms had disappeared and her need for quick relief bronchodilator had decreased to one administration every 2 or 3 weeks, but her spirometry test showed that mild airflow limitation was still present. No exacerbation had occurred in this interval. PREPARATIONS (In Turkey) Non-selective betamimetics EPHEDRIN (Palmer) (Merck Sharp & Dohme) Tablet - Efedrin 0.05 g/Amb. 20 adet.
