Erothin 200
- Erythromycin is a macrolide antibiotic with a broad bacteriostatic
action against many Gram-positive and to a lesser extent some
Gram-negative bacteria, as well as other organisms including
Mycoplasmas, Spirochaetes, Chlamydias, Rickettsias Actinomyces
and some Opportunistic Mycobacteria .
- Orally administered Erythromycin Ethylsuccinate suspension is
readily and reliably absorbed under both fasting and non fasting
conditions.
- The stearate salt for Erythromycin is poorly soluble in water, food
may reduce the absorption of the stearate, although this depends to
some extent on the formulation so the optimal blood level are
achieved when it’s taken on an empty stomach.
- The peak plasma concentrations generally occur between 1 -4 hours
after administration, and have been reported to range between
about 0.3 - 0.5µg /ml after administration of 250mg of
Erythromycin base, and about 0.3 - 1.9 µg/ml after administration
of 500mg .
- The half life of Erythromycin is usually reported to be roughly in
the range 1.5 - 2.5 hours .
- Erythromycin diffuses readily into most body fluids.
- In the presence of normal hepatic function Erythromycin
concentration is increased in the liver and excreted in the bile.
- Erythromycin crosses the placental barrier and excreted in breast
milk.
