Abstract

The invention relates to a slow-release drug with pseudoephedrine and dileitadin, and relative production, wherein it is formed by slow-releaser and quick-releaser; the pseudoephedrine is slow releaser which will release 30-60% in second hour, release 50-80% in fourth hour, and 80% in eighth hour; the dileitadin is quick releaser which will release 75% in 30min. The invention will release quickly after orally intake. The invention also provides relative external releaser character and preparation.

Description

technical field [0001] The invention relates to a compound pseudoephedrine deratadine slow-release preparation for alleviating symptoms of allergic rhinitis associated with cough with abnormal secretions, such as sneezing, runny nose, nasal itching, and tearing, and a preparation method thereof. Background technique [0002] Flu, commonly known as "cold", is a common respiratory disease caused by multiple viruses, 30%-50% of which is caused by a certain serotype of rhinovirus.
