Description
Technical field
The present invention relates to a kind of medicine and its production and use, particularly contains buccal lozenge of cefradine and its production and use.
Background technology
Pharyngitis is the modal disease of puzzlement modern life, is pharyngeal mucous membrane, submucous tissue and adenoid diffuse inflammation, often is the part of upper respiratory tract infection.Be divided into acute and chronic two kinds clinically.Acute pharyngitis is many in autumn and winter and morbidity at the end of winter and the beginning of spring.Pathological changes ordinary wave and whole pharyngeal cavity also can limit to a place.Can cause by virus, antibacterial and physical chemical factor and high temperature, dust, fumagine, irritative gas etc.Bacterial infection is based on gram-positive coccis such as streptococcus, staphylococcus and Diplococcus pneumoniaes.Wherein serious with A group group B streptococcus causer, antibacterial or toxin enter blood, can cause the purulent lesion of organ at a distance, are called acute septic pharyngitis.Treat with oral or injection antibiotics control infection.
The chronic pharyngitis course of disease is very long, and the symptom stubbornness is often by due to the local infection or general pathological changes secondary, with chronic pathological changes repeatedly acute attack be its characteristics, in many cases, acute attack is to be caused by bacterial infection, therefore, suitable antibacterial therapy helps to control acute symptom.
Acute tonsillitis is a kind of non-specific acute inflammation of very common palatine tonsil, often with to a certain degree pharyngeal mucous membrane and swallow adenoid acute inflammation.Main pathogenic bacterium are streptococcus, staphylococcus, Diplococcus pneumoniae.Adenovirus also can cause primary disease.Antibacterial and virus mixed infection are quite a few to be seen.Antibacterial may be extraneous the intrusion, also may be the antibacterial that is hidden in the tonsillar crypts, when Abwehrkraft des Koepers because of cold, humidity, overworked, have a delicate constitution, tobacco and wine are excessive, when factors such as harmful gas stimulation reduce suddenly, due to bacterial reproduction is strengthened.Acute tonsillitis is acute attack repeatedly on chronic tonsil basis often.Clinical manifestation aversion to cold, hyperpyrexia, pharyngalgia, aggravation etc. when swallowing can the concurrent rheumatic fever relevant with hemolytic streptococcal infection, multiple general diseases such as acute glome-rulonephritis, myocarditis, arthritis.Treatment adopts pain relieving to bring down a fever, oral or injection antibiotics control infection.
The oral cavity infection disease mainly comprises dental disease, periodontal and the disease of cari oris mucosa, as dental caries, pulpitis, periapical periodontitis, periodontitis, recurrent aphtha, oral ulcer, oral leukoplakia, monilial stomatitis, pericoronitis, necrotic stomatitis, thrush, gingivitis, membranous stomatitis, periodontal disease, herpetic stomatitis etc.Antibacterial is the important paathogenic factor that causes the oral cavity infection disease.Intraoral have a large amount of Gram-positives and a gram negative bacteria, and its value volume and range of product all occupies first of the whole body.According to the study, contain antibacterial in every milliliter of saliva and reach 1.5 hundred million.Under certain conditions, incorrect etc. when food debris accumulation, crowded dentition, method for brushing teeth, form dental plaque, tartar, when the kind of antibacterial changes, the amount of pathogenic bacterium increases or passive protective physical fitness descends, cause the generation of oral cavity infection disease.Therefore, oral cavity infection disease is caused by the various bacteria synergism.The patient often has symptoms such as toothache, gingival hemorrhage, redness, odontoseisis displacement, halitosis.Swelling and aching of gum, pyorrhea also can be used as infection focus, cause such as systemic diseases such as arthritis, the heart, cerebrovascular disease.
Treat pharyngitis, tonsillitis and oral cavity infection that bacterial infection causes, often select the antibiotics of resisting gram-positive bacteria for use, the antibiotics of the anti-gram negative bacteria of part also has therapeutical effect.Cefradine is a first generation cephalosporin, to not producing penicillinase and producing the good antibacterial action of part bacterial strain tool of penicillinase staphylococcus aureus, coagulase negative staphylococcus, gram positive coccus such as A group Hemolytic streptococcus, streptococcus pneumoniae and Streptococcus viridans.How responsive the anaerobism gram positive bacteria is to cefradine, and bacteroides fragilis presents drug resistance to cefradine.Methicillin-resistant staphylococcus, Enterococcus are to the cefradine drug resistance.Cefradine is similar to cefalexin to the effect of gram-negative bacteria to gram positive bacteria.Cefradine has certain effect to Diplococcus gonorrhoeae, also has an activity to producing the enzyme Diplococcus gonorrhoeae; Active relatively poor to hemophilus influenza.Mechanism of action is identical with other cephalosporins, for suppressing the synthetic of bacteria cell wall.Be applicable to respiratory tract infection such as acute pharyngitis, tonsillitis, otitis media, bronchitis and pneumonia, urogenital infections and skin soft-tissue infection etc. due to the sensitive organism.Cefradine has been developed into tablet, capsule, injection etc., all adopts whole body administrations such as oral or injection.Be easy to cause the local pain reaction when using inconvenience, administration in view of injection.Oral absorption such as tablet and capsule is slower, and entering behind the blood distributes by whole body dilutes medicine in blood, make medicine lower at the blood drug level of diseased region, and it is also longer to reach time of effective blood drug concentration at diseased region, influences its effective antibacterial efficacy.Therefore, the buccal lozenge of development cefradine by the oral cavity buccal, directly acts on diseased region with high concentration medicine, is used for pharyngitis, pharyngoamygdalitis and oral cavity infection treatment of diseases, can overcome above-mentioned shortcoming, and strong auxiliary treatment means is provided.
