Motivation for starting
• April 2001: Regional course on Psoriasis with consultant dermatologist
• July 2001: Dermatologist meeting in Leiden academic medical centre
• July 2001: Inventory of interests among health care members
• December 2001: Start national projectgroup: multidisciplinary agreements dermatological pharmacy compounded medicines
• April 2002: Start regional project
BAK-Workshop 16-11-2007 4
Introduction• Dermatological preparation is 44-57% of the ‘Magistralrezeptur’.
• 50% is a non-standardized dermatological prescription.
• Prescriber is 20% dermatologist and 80% general practitioner.
• Both prescriber and compounder are responsible for rational and technical high quality pharmacy compounded medicines.

BAK-Workshop 16-11-2007 5
Problems• Diversity in prescribing behaviour • Difficult communication
– Dispensing irrational and low quality preparations– Pharmacists change prescriptions without consulting
the prescribing doctor– Miscellaneous or no protocols used– Inconsistent patient information– Patient has to wait for the preparation
BAK-Workshop 16-11-2007 6
Aims• To improve efficient pharmaceutical care to individual
patients using dermatological preparations• To increase quality and effectiveness of dermatological
preparations
– Promote rational prescribing behaviour – Enhance standardization (80% at dispensing)– Implementation of a regional formulary– Promote the use of protocols/ instructions – Improve the communication and exchange of
information between regional health care providers
BAK-Workshop 16-11-2007 7
Methods
• Create support: “soundboard group”
• Appoint working groups
• Base line measurement: Inventory of ‘Magistralrezeptur’
• Assessment of the rationality of dermatological pharmacy compounded medicines
• Formulary and agreements non-formulary preparations
• Implementation among health care members
• Effect-measurement
BAK-Workshop 16-11-2007 8
Assessment inventory of “Magistralreceptur
Reaching consensus is difficult because of
• Differences in knowledge level care members• Different therapy opinions among
dermatologists related to education region• Prescribing is tradition and empiry based • Different opinions on user friendly• Reimbursement difficulties

Do you believe the efficacy of the
preparations prescribed or
dispensed by yourself is
convincing?
BAK-Workshop 16-11-2007 10
Concentration of corticosteroids
• 0.025%, 0.1% and 0.5% triamcinolone acetonide in a topical preparation have the same biologic activity.
• 1.0% and 2.5% hydrocortisone acetate have equal therapeutic effectiveness
BAK-Workshop 16-11-2007 11
Do you prescribe or dispense
brand name products with an
extra component?
BAK-Workshop 16-11-2007 12
BAK-Workshop 16-11-2007 13
Adds to brand name products
Medical information manager:• “There are only few data known on clinical
efficacy and safety of combination preparations (components added to brand products). Therefore the Laboratory of Dutch Pharmacists (LNA) advises against.”
• ”The test results only prove physical stability of the combination preparation for 35 days. On efficacy of the preparation nothing can be said.”

Assessment criteria non-standardized products Approved by Klankbordgroep RADA project 13 april 2003
• Farmacotherapeutic rational
• efficacy is reasonable
• safety is reasonable
• no obsolete components and ex-FNA (Formulary Dutch Pharmacists)-preparations (Dermatica op Recept)
• Chemical stability components
• Physical stability of the combination (Avoid adding agents to brand name products)
• Stability of the preparation
• User friendly (preferable in one tube)
BAK-Workshop 16-11-2007 16
Regional standardized (RA) preparations
• RA’s to fulfill the wishes of dermatologists
• RA’s follow the assessment criteria of non-standardized products regional standardized products
• The stability of RA’s is 1 month untill research has proven a longer period of stability
• Compounding instructions for all RA’s on www.stevenshof.nl
