Magnesium pidolate in the treatment of seasonal allergic rhinitis. Preliminary data.

This paper describes how the authors, after examining the calcium modulating action of the Mg ion and its antihistamine-like action, tested a salt containing Mg (Mg pidolate, MAG2) in the clinical treatment of seasonal allergic rhinitis. A total of 38 hayfever subjects were studied. They were given 1.5 g Mg salt three times a day for one month (oral MAG2 vials); placebo was used as a control in a randomized double-blind study. The efficacy of the product was assessed using the following criteria: intensity of rhinorrhoea, daily consumption of Kleenex tissues, number of sneezes in a day, intensity of lacrimation. The results were analysed using Student's t test and demonstrated the clinical efficacy of the product in the control of seasonal allergic rhinitis symptoms (P less than 0.001).
