In addition, it is possible to view the therapeutic range individually for the patient's weight as guided by some medical bibliographies and the adjustment of this range by the user depending on the objective and clinical judgment. Thus, the application increases patient safety when prescribing these drugs reducing the risk of calculation errors by the professional. The application also has messages to warn about photosensitive solutions and medications that must be diluted in a specific medium such as physiological solution or glucose solution, thus preventing changes in their therapeutic properties. The application is available in english, portuguese and spanish.
