Description
Ryth is a macrolide with antibacterial properties similar to erythromycin. It is active against Gram-positive bacteria like staphylococci, streptococci, listeria, and corynebacteria; Gram-negative bacteria such as gonococci, Haemophilus influenzae, Haemophilus ducreyi, Legionella, and campylobacter; atypical pathogens like Mycoplasma and Chlamydia. Ryth has been found useful in the treatment of upper and lower respiratory tract infection, otorhinolaryngological, skin, dental, and genital infections. It is well tolerated by adults and children.
Pharmacology
Roxithromycin inhibits protein synthesis by irreversibly binding to the 50s ribosomal subunits, thus blocking the transpeptidation or translocation reactions of susceptible organisms, resulting in stunted cell growth.
Dosage & Administration
- Adult dose: The usual dose for adults is one 300 mg tablet once daily or one 150 mg tablet twice a day for at least two days after resolution of symptoms, a normal course of therapy is between 5 and 10 days. Roxithromycin is best administered on an empty stomach. In severe hepatic impairment, the dose is 150 mg once daily.
- Pediatric dose: The dose for children is 2.5 to 5 mg/kg body weight twice a day.
Interaction
Ryth does not have any affinity for cytochrome P-450 binding sites and thus is unlikely to produce drug interaction mediated by this enzymatic system. Ryth shows mild interaction with theophylline, though this has not been found to produce clinically relevant effects. Alteration in the pharmacokinetics of carbamazepine or warfarin has not been found. Antacids, H2-receptor antagonists, and food have no effect on the absorption of Ryth.
Contraindications
Roxithromycin should not be administered simultaneously with ergotamine or its derivatives as it may provoke arterial spasm and severe ischemia.
