    The correct answer is 0.44ml

    For information, promethazine is a neuroleptic antihistamine inhibitor of H1 receptors of the phenothiazine family. It is a medicine used in the treatment of allergy (like rhinitis) and transient insomnia.

    To respond to this exercise, it is necessary to cross-multiply.

    In the antihistamine bottle solution:

    25 mg corresponds to 1 ml

    11 mg corresponds to: 11/25 = 0.44 ml of the solution.

    This 0.44ml is taken from the bottle and put to the syringe.
