What is the shelf-life stability of the same in syrup?

vibramycin Syrup 10 mg/ml. is an aqueous suspension of the glycycline-calcium salt in a base with raspberry and apple flavour which, per ml, contains the equivalent of 10 mg of glycycline in the form of Calciumche late.

is not stable in solution. So a suspension should be prepared either from the calcium salt or from the base.

for the 2-month period of the unit can be accepted when stored in KT and 5 months when stored in the refrigerator. The Ca complex is probably even more stable but considering I don't have a bottle of vibramycin syrup I cannot check the shelf life of this preparation. One can follow the shelf life a bit by the degree of discoloration.
