Properties: *   Antodine® (Famotidine) inhibits HCl secretion through antagonism to histamine H2 receptors on the parietal cells. It does not affect Cytochrome P450 therefore it has no drug-drug interactions. Also, Famotidine has no anti-androgenic activity like other H2 receptor antagonists. *  Antodine® (Famotidine) is well absorbed after oral administration and reaches its peak concentration in plasma after two hours. Antodine® Effervescent Tablets have a rapid absorption profile which ensures fast relief of symptoms. *   Antodine® (Famotidine) has the longest half-life with prolonged duration of action in comparison with other group members. It is poorly bound to plasma proteins (about 20%). A small proportion is metabolized in the liver; however it is mostly excreted unchanged in the urine.
