<s>[INST] my grandmother is 65 yrs old and recently she had a sour throat which turned so severe that she could not even speak properly.doctor took x ray and the report says "LUNG FIELD REVEALS MILDLY PROMINENT BRONCHI O-VASCULAR MARKINGS". her ESR  is 20 mm.and the doctor says MILD BRONCHITIS. SHE IS GIVEN RABON-20,XYZOL,MONTELUKAST SODIUM,LEVOCYTRYZENE DYHYDROCHLORIDE, AND LYCO GEL since about a week with no improvement. PLEASE TELL YOUR OPINION [/INST] Thanks for your question on Chat Doctor. I can understand your concern. She is not improving because she is not taking appropriate treatment for bronchitis. Bronchitis needs inhaled treatment based on severity of the disease. So better to get done PFT (Pulmonary Function Test) first.PFT will not only diagnose bronchitis, but it will also tell you about severity of the disease and treatment is based on severity only. She will mostly improve with inhaled bronchodilators (formoterol or albuterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone).Don't worry, she will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wishing good health to your grandmother. Thanks. </s>
