Aqua-Mephytin

Aqua-Mephytin - General Information

Aqua-Mephytin is often called vitamin K1. It is a fat-soluble vitamin that is stable to air and moisture but decomposes in sunlight. It is found naturally in a wide variety of green plants. Phylloquinone is also an antidote for coumatetralyl. Vitamin K is needed for the posttranslational modification of certain proteins, mostly required for blood coagulation.

 

Pharmacology of Aqua-Mephytin

Aqua-Mephytin is a vitamin, indicated in the treatment of coagulation disorders which are due to faulty formation of factors II, VII, IX and X when caused by vitamin K deficiency or interference with vitamin K activity. Aqua-Mephytin aqueous colloidal solution of vitamin K1 for parenteral injection, possesses the same type and degree of activity as does naturally-occurring vitamin K, which is necessary for the production via the liver of active prothrombin (factor II), proconvertin (factor VII), plasma thromboplastin component (factor IX), and Stuart factor (factor X).

Aqua-Mephytin Interactions

Temporary resistance to prothrombin-depressing anticoagulants may result, especially when larger doses of phytonadione are used. If relatively large doses have been employed, it may be necessary when reinstituting anticoagulant therapy to use somewhat larger doses of the prothrombin-depressing anticoagulant, or to use one which acts on a different principle, such as heparin sodium.
Laboratory Tests
Prothrombin time should be checked regularly as clinical conditions indicate.

 

Aqua-Mephytin Contraindications

Hypersensitivity to any component of this medication.

 

Additional information about Aqua-Mephytin

Aqua-Mephytin Indication: For the treatment of haemorrhagic conditions in infants, antidote for coumarin anticoagulants in hypoprothrombinaemia
Mechanism Of Action: Vitamin K is an essential cofactor for the gamma-carboxylase enzymes which catalyze the posttranslational gamma-carboxylation of glutamic acid residues in inactive hepatic precursors of coagulation factors II, VII, IX and X. Gamma-carboxylation converts these inactive precursors into active coagulation factors which are secreted by hepatocytes into the blood. Supplementing with Aqua-Mephytin results in a relief of vitamin K deficiency symptoms which include easy bruisability, epistaxis, gastrointestinal bleeding, menorrhagia and hematuria.

Drug Type: Small Molecule; Approved
Other Brand Names containing Phytonadione: Aqua-Mephytin; AquaMEPHYTON; Combinal K1; K-Ject; Kativ N; Kephton; Kinadion; Konakion; Mephyton; Mono-Kay; Monodion; Synthex P;
Absorption: Oral phytonadione is adequately absorbed from the gastrointestinal tract only if bile salts are present. After absorption, phytonadione is initially concentrated in the liver, but the concentration declines rapidly. Very little vitamin K accumulates in tissues.
Toxicity (Overdose): The intravenous LD50 of phytonadione in the mouse is 41.5 and 52 mL/kg for the 0.2% and 1% concentrations, respectively.
