MINGUEZ, A.  and  ANDRES, J. de. The magistral formulation in the WHO analgesic scale as a pharmaceutical care strategy. Rev. Soc. Esp. Dolor [online]. 2005, vol.12, n.4, pp.235-241. ISSN 1134-8046.

A magistral formulation (MF) is a drug prepared for a given patient by the pharmacist or under his/her supervision, specifically according to a detailed medical prescription of the medicinal substances that it contains and applying the technical and scientific standards of the pharmaceutical art, that is dispensed by the pharmacist providing the patient with adequate information. This is an possible cost-effective strategy that can fill in a safe and effective way some of the therapeutic gaps or deficiencies that are found in the analgesic arsenal available in the market. The participation of the hospital pharmacist in the MF is regulated by law in terms of manufacturing and production, but the integration of this professional in the clinical team that provides care to patients facilitates the identification of therapeutic deficiencies that can be overcame by the MF. In this paper we describe the preparations, elaborated as MF and classified according to their route of administration, that are provided by the assistant hospital pharmacist of the Pain Unit at the General University Hospital Trust of Valencia, as well as their position within the WHO analgesic scale. Morphine preparations in drop, syrup or lidocain gel are prepared for their oral administration; solutions of acetic acid, dexametasone and lidocaine with different strengths are prepared for their transdermal administration; morphine and capsaicine plus ketamine gels are prepared for their topical administration, as well as injectable preparations for their intraarticular or intraspinal administration.
