Important message from AB Science

Dear customer, 

Our laboratory has recently experienced a delay in the provision of starting materials used in the composition of Masivet tablets. These delays have forced us to change our supply and this change requires filing a variation of our marketing authorization with the EMA. This variation will of course have no impact on the efficiency and tolerance of our product. Nevertheless, the EMA imposes a 2-month delay to validate this change, so we will have to undergo a product rupture till mid-January 2023.
Of course we are aware of the problems that this shortage causes for your patients, and of your daily relationship difficulties with your clients. That is why we do everything we can to shorten the time frame imposed by regulatory authorities, and restore the availability of our product as quickly as possible.

In the meantime, it is possible to order contemporaneous preps from FRANCEPREP in Marseille:

  • Franceprep : 00 33

  • Address : 180 Rue Rabelais, 13016 Marseille.

Please accept our apologies and do not hesitate to contact me for more information.

Best regards.
