100mg Corvental-D Capsule - per Capsule

Description

Corvental-D 100mg Capsules contain theophylline, a medicine licensed for the treatment of bronchitis and Congestive Heart Failure in dogs. Theophylline is a bronchodilator, meaning that it helps widen the airways by relaxing the smooth muscle around them. This is useful when airway narrowing contributes to coughing, wheezing or difficulty moving air through the lungs. Corvental-D 100mg is an oral, slow-release capsule formulation with a once-daily administration schedule. Each capsule contains 100mg of theophylline and is supplied individually on this listing. The medicine acts on the function of the respiratory system, rather than simply suppressing the outward sign of coughing. Its effect on airway muscle can reduce bronchospasm, allowing air to pass more freely where reversible narrowing is contributing to a dog’s respiratory discomfort.

Bronchitis is inflammation of the bronchi, the passages that carry air into the lungs. Inflammation can make these airways sensitive, increase mucus and trigger coughing. Some dogs develop ongoing bronchial disease, with coughing that recurs over time or becomes more noticeable during excitement or activity. Corvental-D 100mg is used when theophylline is appropriate for the dog’s respiratory condition, particularly where airway constriction contributes to the signs. A dog may also tire more easily or take longer to settle after exercise when breathing is less efficient. Corvental-D 100mg relaxes airway muscle but does not remove every cause of bronchitis. Airway inflammation, infection and environmental irritation may each require a different part of the treatment plan. The purpose of the bronchodilator is to improve airflow within that broader management of respiratory disease.

Theophylline belongs to a group of medicines called methylxanthines. Corvental-D 100mg has several pharmacological effects, including smooth muscle relaxation and stimulation of respiration. By relieving bronchospasm, it reduces the muscular tightening that can narrow the air passages. Theophylline also affects the heart, increasing the strength of contraction of the myocardium, and can increase urine production through an action on the kidneys. These effects help explain why Corvental-D 100mg has a licensed indication for Congestive Heart Failure as well as bronchitis. They also explain why its suitability depends on the dog’s overall clinical condition. A cough caused by airway disease is different from breathing difficulty caused by fluid accumulation, even though both can occur in dogs with heart or respiratory problems. The same outward symptom does not always call for the same medicine.

The slow-release design of Corvental-D 100mg allows theophylline to be delivered over a longer period than an immediate-release preparation. This supports the authorised once-daily schedule and reduces the need for repeated administration throughout the day. The licensed dose is 20mg per kilogram of bodyweight once daily, with particular emphasis in the product information on accurate weighing and not exceeding that amount. Corvental-D 100mg contains a fixed quantity in each capsule; the capsule count therefore depends on the dog’s treatment directions. Different theophylline formulations can release the active ingredient at different rates, so the formulation is an essential part of the medicine’s identity. The capsule contents should not be crushed or chewed, as damaging a modified-release preparation may alter how the active ingredient is delivered. Administration should preserve the intended release characteristics of the product.

For a dog with chronic airway disease, treatment is often combined with measures that reduce respiratory irritation. Keeping the sleeping area free of smoke, strong sprays and excessive dust can help make the environment more comfortable. Exercise may need to be paced to the dog’s tolerance, especially during hot weather or periods when coughing is more troublesome. Corvental-D 100mg can improve airflow where bronchospasm is present, but it does not make strenuous exercise appropriate during a respiratory flare-up. Theophylline treatment may also be part of a cardiac plan when congestive heart failure is diagnosed, alongside medicines with other actions. Corvental-D 100mg is not an emergency remedy for a dog that is struggling to breathe. Laboured breathing at rest, blue or grey gums, collapse or a rapidly deteriorating breathing pattern requires immediate veterinary attention.

Corvental-D 100mg can cause restlessness, agitation, vomiting, diarrhoea, increased thirst or urination, and reduced appetite. Theophylline also stimulates the nervous system, and twitching, marked excitement or convulsions require treatment to be stopped and urgent veterinary advice. The medicine must not be used in dogs with a history of epileptiform seizures, or alongside beta-sympathomimetic medicines because their effects may be additive. Liver disease needs particular care, and some antibiotics and anticonvulsants can change the amount of theophylline in the bloodstream. Corvental-D 100mg capsules are blue and white, with “Th100” printed on each half. Keep them in their dispensing packaging, in a dry place below 30°C, and away from children and other animals. Prompt advice is needed after suspected accidental extra dosing, even if obvious symptoms have not yet appeared.

What is Corvental-D 100mg used for in dogs?

Corvental-D 100mg is licensed for bronchitis and congestive heart failure in dogs. It contains theophylline, which relaxes airway smooth muscle and relieves bronchospasm. This can improve airflow where narrowed airways contribute to respiratory signs. The oral capsule formulation is administered once daily under its licensed schedule.

How does Corvental-D help a dog breathe?

Theophylline relaxes the smooth muscle around the bronchi, helping widen narrowed air passages. This bronchodilator effect can make movement of air easier when bronchospasm is present. It also stimulates respiration, although inflammation, infection or fluid accumulation may require additional treatments with different actions alongside theophylline.

Is Corvental-D a cough suppressant?

Its main respiratory role is bronchodilation, rather than directly suppressing the cough reflex. Improving airflow may help a dog whose cough accompanies bronchitis, but coughing has many causes. A heart-related cough or another respiratory disorder needs the correct diagnosis and treatment for the underlying problem.

How often is Corvental-D 100mg given?

The licensed schedule is once daily, at 20mg of theophylline per kilogram of bodyweight. The product information emphasises accurate weighing and not exceeding that amount. Each capsule contains 100mg, so the number of capsules depends on the dog’s weight and the individual administration directions.

Is Corvental-D a slow-release medicine?

Yes. Corvental-D uses a slow-release theophylline formulation suited to its once-daily schedule. Release characteristics differ between theophylline products, so another formulation is not automatically interchangeable. Crushing or chewing the capsule contents can interfere with the intended release and should be avoided during administration to the dog.

Can Corvental-D be used for heart failure?

Congestive heart failure is included in its licensed indications for dogs. Theophylline has effects on breathing, heart muscle contraction and urine production. Its role depends on the dog’s condition and wider treatment plan; it should not be assumed to replace other established cardiac medicines automatically.
