Roxithromycin Medchem Uses


Roxithromycin Medchem indications

infoAn indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

Roxithromycin Medchem is indicated for the treatment of the following types of mild to

moderately severe infections caused by or likely to be caused by susceptible

micro-organisms: • upper respiratory tract infection - acute pharyngitis, tonsillitis and


• dental infections

• lower respiratory tract infection - acute bronchitis; acute exacerbations

of chronic bronchitis and community acquired pneumonia

• skin and skin structure infections

• non-gonococcal urethritis.

Uses of Roxithromycin Medchem in details

infoThere are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.

Roxithromycin Medchem is used to treat ear, nose and throat infections, pneumonia (lung infection), skin infections and infections of the genitalia.

Roxithromycin Medchem description

Roxithromycin Medchem is a semi-synthetic macrolide antibiotic. It is very similar in composition, chemical structure and mechanism of action to erythromycin, azithromycin, or clarithromycin. Roxithromycin Medchem prevents bacteria from growing, by interfering with their protein synthesis. Roxithromycin Medchem binds to the subunit 50S of the bacterial ribosome, and thus inhibits the translocation of peptides. Roxithromycin Medchem has similar antimicrobial spectrum as erythromycin, but is more effective against certain gram-negative bacteria, particularly Legionella pneumophila. It can treat respiratory tract, urinary and soft tissue infections. It is in the United States, but is available in Australia.

Roxithromycin Medchem dosage



Susceptible infections

Adult: 150 mg bid or 300 mg once daily for 5-10 days in susceptible infections.

Child: 6-40 kg: 5-8 mg/kg daily.

Renal impairment: Dosage adjustment may be required.

Hepatic impairment: Usual daily doses should be halved in hepatic impairment.

Roxithromycin Medchem interactions

Roxithromycin Medchem has a much lower affinity for cytochrome P450 than

erythromycin, and consequently has fewer interactions. Interactions may be

observed, however, with drugs that bind to alpha-1-acid glycoprotein, e.g.


Roxithromycin Medchem does not appear to interact with oral contraceptives,

prednisolone, carbamazepine, ranitidine or antacids.

Theophylline. A study in normal subjects concurrently administered

Roxithromycin Medchem and theophylline has shown some increase in the plasma

concentration of the latter. While a change in dosage is usually not required,

patients with high levels of theophylline at commencement of treatment

should have levels monitored.

Ergot alkaloids. Reactions of ergotism with possible peripheral necrosis have

been reported after concomitant therapy of macrolides with vasoconstrictive ergot alkaloids, particularly ergotamine and dihydroergotamine. Because a

clinical interaction with Roxithromycin Medchem cannot be excluded, administration of

Roxithromycin Medchem to patients taking ergot alkaloids is contraindicated.

Disopyramide. An in vitro study has shown that Roxithromycin Medchem can displace

protein bound disopyramide; such an effect in vivo could result in increased

serum levels of disopyramide. Consequently, ECG and, if possible,

disopyramide serum levels should be monitored.

Terfenadine. Some macrolide antibiotics (e.g. erythromycin) may increase

serum levels of terfenadine. This can result in severe cardiovascular adverse

events, including QT prolongation, torsades de pointes and other ventricular

arrhythmias. Such a reaction has not been documented with Roxithromycin Medchem,

which has a much lower affinity for cytochrome P450 than erythromycin.

However, in the absence of a systematic interaction study, concomitant

administration of Roxithromycin Medchem and terfenadine is not recommended.

Astemizole, cisapride, pimozide. Other drugs, such as astemizole, cisapride

or pimozide, which are metabolised by the hepatic isozyme CYP3A4, have

been associated with QT interval prolongation and/or cardiac arrhythmias

(typically torsades de pointes) as a result of an increase in their serum level

subsequent to interaction with significant inhibitors of this isozyme, including

some macrolide antibacterials. Although Roxithromycin Medchem has no or limited ability

to complex CYP3A4 and hence to inhibit the metabolism of other drugs

processed by this isozyme, a potential for clinical interaction of Roxithromycin Medchem

with the above mentioned drugs cannot be either ascertained or ruled out in

confidence. Thus, concomitant administration of Roxithromycin Medchem and such drugs

is not recommended.

Warfarin. While no interaction was observed in volunteer studies,

Roxithromycin Medchem appears to interact with warfarin. Increases in prothrombin time

(international normalised ratio (INR)) have been reported in patients treated

concomitantly with Roxithromycin Medchem and warfarin or the related vitamin K

antagonist phenprocoumon, and severe bleeding episodes have occurred as

a consequence.

Digoxin and other cardiac glycosides. A study in healthy volunteers has

shown that Roxithromycin Medchem may increase the absorption of digoxin. This effect,

common to other macrolides, may very rarely result in cardiac glycoside

toxicity. This may be manifested by symptoms such as nausea, vomiting,

diarrhoea, headache or dizziness. Cardiac glycoside toxicity may also elicit

heart conduction and/or rhythm disorders. Consequently, in patients treated

with Roxithromycin Medchem and digoxin or another cardiac glycoside, ECG and, if

possible, the serum level of the cardiac glycoside should be monitored. This is

mandatory if symptoms suggesting cardiac glycoside overdosage have


Midazolam. Roxithromycin Medchem, like other macrolides, may increase the area

under the midazolam concentration-time curve and the midazolam half-life.

Thus, the effects of midazolam may be enhanced and prolonged in patients treated with Roxithromycin Medchem. There is no conclusive evidence for an interaction

between Roxithromycin Medchem and triazolam.

Cyclosporin. A slight increase in plasma concentrations of cyclosporin A has

been observed. This does not generally necessitate altering the usual dosage.
