This is the extract or extrait of a fragrance and represents the scent in its purest form. This often creates a smooth and round texture, which is hard to achieve with the dilution represented in the other concentrations of fragrance. Some drugs may have Authority Required (Streamlined) status which does not require an explicit approval from Medicare, instead the doctor can use the Authority code found in the published Schedule for a given drug/indication. Authority to prescribe an Authority medicine is granted for specific indications and/or for certain patient circumstances. Authority may be obtained by telephone to Medicare Australia (known as "phone approval") or in writing from an authorised delegate of the Minister for Health. EDT’s are not as highly concentrated in oils and elixirs as an EDP or Perfume would be and contain one to three per cent of fragrance oils. This impacts the ability of the fragrance to last and around eighty percent of the oils in an EDT fragrance will evaporate within three hours of application. Prescriptions must be written on an Authority Prescription Form, and the approval number must be noted on the prescription. Pharmacists cannot dispense the item as a pharmaceutical benefit unless it has been approved by Medicare Australia (indicated by the presence of the approval number).

Eau de Parfum or EDP is one of the most popular forms of fragrance. Eau de Parfum contains between seven to fourteen per cent of fragrance oils and perfume elixirs and is the second strongest, and longest lasting means of wearing a fine fragrance. Some PBS medications are restricted and require prior approval from Medicare before a doctor is able to prescribe them on the PBS. This prior approval to prescribe grants the doctor the Authority to prescribe the desired medicine and have it funded under the PBS.
