| Pharmacological
Actions :
LIMARIN® has a potent hepatoprotective effect by various
mechanisms facilitating physiology and metabolism of hepatocytes. Free radical
scavenging (antioxidant) action is via the glutathione system and superoxide dismutase.
LIMARIN stimulates synthesis of polymerase l, enhances ribosomal protein synthesis
and exerts a membrane stabilising effect.
LIMARIN® also reduces prostaglandin
Synthesis. LIMARIN® is known for its hepatoprotective action against
hepatic glutathione depletion induced by ethyl alcohol and paracetamol in animal
studies. LIMARIN® reduces the turnover of membrane phospholipids and stabilises both extra and intracellular membranes inside hepatocytes. LIMARIN®
also increases the phagocytic activity of the Kupffer cells, contributing to hepatoprotective
and regenerative effects.
Pharmacokinetics : LIMARIN®is
absorbed to the extent of about 50% following an oral dose. The major ingredient,
Silibinin, is concentrated in the liver, reaches high concentration in the bile;
almost 30 times that in plasma; peak levels are attained 2-8 hrs. following oral
dose. Systemic half life is about 6.5 hrs. Main route of elimination is through
the bile. Drug Disease Interactions: None specific. Drug
Drug Interaction: None reported so far. Indications:
