Durasalyn-Cr Capsule is a combination of respiratory-related medicine containing Salbutamol (bronchodilator) and Theophylline (xanthine and phosphodiesterase inhibitor). Together it helps in the management of chronic conditions of the respiratory system including asthma and chronic obstructive pulmonary disease (COPD). Asthma is a breathing problem in which airways narrow, swell, and produce extra mucus, leading to difficulty in breathing. On the other hand, COPD is a group of progressive lung diseases, with emphysema (shortness of breath) and chronic bronchitis (inflammation of bronchial tubes). Initially, it may be mild, but it can lead to total blockage of airways and damage the lungs in severe cases.

Durasalyn-Cr Capsule helps in the management of asthma and chronic obstructive pulmonary disease (COPD) by relaxing and widening the narrowed or blocked airways (bronchial tubes) of the lungs making it easier to breathe in. Durasalyn-Cr Capsule is given to treat an asthma attack when it first starts (an acute attack) and for wheezing (a whistling sound during breath) induced by factors like cold or exercise.

Durasalyn-Cr Capsule should be taken as prescribed by the doctor. You may experience nausea, vomiting, restlessness, tremor, headache, muscle cramp, and increased heart rate in some cases. Most of these side effects of Durasalyn-Cr Capsule do not require medical attention and gradually resolve over time. However, if the side effects are persistent, reach out to your doctor.

Try not to stop taking this medicine of your own. Let your doctor know about this, as it may cause withdrawal symptoms. Do not take this medicine if you have any lung disease, muscle weakness (myasthenia gravis), sleeping disorder or difficulty sleeping (sleep apnoea), severe liver disease, or problem with alcohol or other prescription recreational drugs. Durasalyn-Cr Capsule is a habit-forming drug, and, hence there is a risk of dependence on this medicine. Before stopping this medicine, contact a doctor as it may cause withdrawal symptoms like anxiety, increased heart rate, tremors, or general unwell feeling.

Theophylline belongs to the class of xanthines and Salbutamol is an adrenergic agent (selective beta-2-adrenoreceptor agonist) used in the systemic treatment of obstructive airway diseases like asthma and COPD. Both Salbutamol and Theophylline work by relaxing the airway in the lungs and making it easier to breathe in. Durasalyn-Cr Capsule is given to treat an asthma attack when it first starts (an acute attack) and for wheezing (a whistling sound during breath) induced by factors like cold or exercise in all the age groups from children to the elderly.

Durasalyn-Cr Capsule should be taken with caution if you are taking blood pressure-lowering medicines like propranolol. Consumption of alcohol should be avoided as it may worsen your condition. Do not abruptly stop taking Durasalyn-Cr Capsule as it may lead to withdrawal syndrome and unwanted side effects. Durasalyn-Cr Capsule may cause an increase in the uric acid, so close monitoring of uric acid is required. Durasalyn-Cr Capsule should not be given in the conditions of hypersensitivity (allergic reactions), thyrotoxicosis (excess thyroid hormone), fever, liver impairment, heart failure, high blood pressure (hypertension), irregular heart rhythm (arrhythmia), pulmonary oedema, diabetes, history of peptic ulcer and seizures (fits). Patients using medicines for depression should use Durasalyn-Cr Capsule only after consulting a doctor. Durasalyn-Cr Capsule is not recommended for use in neonates or infants, pregnancy, and lactation.

Drug-Drug Interactions: This medicine may interact with non-selective beta-blocking drugs (propranolol), antidepressants (clomipramine), anti-anxiety drugs (diazepam, flurazepam, lorazepam, midazolam), blood clot drugs (pentoxifylline, ticlopidine), gout drugs (allopurinol), heart rhythm drugs (mexiletine, propafenone, verapamil), birth control drugs (estrogen), immune disorder drugs, seizure drugs (phenobarbital, phenytoin), quinolone antibiotics (levofloxacin, gatifloxacin, moxifloxacin, sparfloxacin), muscle relaxant (pancuronium bromide and acid-lowering drugs (cimetidine). So, they should not usually be prescribed together.

Drug-Food Interactions: Durasalyn-Cr Capsule can interact with other medications, vitamins, or herbs you may be taking.

Drug-Disease Interactions: Please tell your doctor before taking Durasalyn-Cr Capsule if you have a gastric or peptic ulcer, a serious infection called sepsis, liver disease (especially cirrhosis or hepatitis), fluid in your lungs, heart problems, a thyroid disorder, seizures, kidney disease.

• Eat a healthy diet, especially green leafy vegetables, and strictly do not consume alcohol and caffeine (coffee, tea, cola drinks, and chocolate). Caffeine is a stimulant and can decrease $ name's calming effects, and alcohol can enhance $ name's effects.
• Smoking should be avoided while taking Durasalyn-Cr Capsule as it can alter theophylline's blood levels, which may affect the dosing.
• Maintaining hygiene like washing hands after coming from outside is essential, as people with asthma/COPD are at a greater risk of infections.
• Stay active and exercise regularly to improve quality of life and increase tolerance to shortness of breath.
• Talk with a family member if you feel low or stressed, as it improves symptoms of COPD and keeps it under control.
• Shortness of breath can be eased by doing pursed-lip breathing exercises. In this, relax your neck and shoulder muscles, breathe in with your nose for two seconds and breathe out through pursed lips for four seconds. Breathing techniques and such exercises will help you to improve your breathing capacity and lung health.

• Tell your doctor if your using beta-blocker eg (propranolol).

Asthma: It is a breathing problem in which airways narrow, swell, and may produce extra mucus, leading to breathing difficulty with a whistling sound (wheezing) in laboured breathing conditions.

Chronic obstructive pulmonary disease (COPD): It is a group of progressive lung diseases, with emphysema (shortness of breath) and chronic bronchitis (inflammation of bronchial tubes). Initially, it may be mild, but it can lead to total blockage of airways and damage the lungs in severe cases.
