Increased plasma concentration of cabergoline. Increased risk of severe pruritus and cholestatic jaundice with oral contraceptives and hormonal replacement therapy. Increased risk of cardiotoxicity with pimozide. Increased concentrations with sirolimus. Increased risk of respiratory depression with alfentanil. |
Lab Interference
May interfere with measurements of urinary catecholamines and 17-hydroxycorticosteroids. False elevation of serum aspartate aminotransferase (AST) values when measured colorimetrically.

Action
Description:
Mechanism of Action: Troleandomycin, a prodrug of oleandomycin, reversibly binds to 50S subunit of bacterial ribosome blocking the transpeptidation and inhibiting protein synthesis of susceptible bacteria thus inhibiting cell growth. It has general properties similar to erythromycin but is less effective in activity than erythromycin. 1.18g of troleandomycin is approximately equivalent to 1g of oleandomycin. Pharmacokinetics: Absorption: Rapid and complete absorption. Peak plasma concentration of oleandomycin: 2 hr. Excretion: Excreted in faeces and bile. |
