Why was it done?
Hospital Pharmacy Services staff may be exposed to hazardous substances, involving a risk to health. For this reason, is important to identify these substances and measures must be taken to ensure maximum safety for the staff at work. We decided to review the topic when we saw in the Technical Document on Prevention Measures for the Preparation and Administration of Dangerous Drugs, published by the National Institute for Safety and Hygiene at Work (INSHT) there are no specific recommendations for protection of raw materials used in magistral formulas; it only refers to dangerous drugs.
What was done?
Identify health problems involved in handling raw materials that we use in the preparation of magistral formulations. Define personal protective equipment and installations necessary for handling.
Improve work safety of area’s staff.
How was it done?
We have to update raw materials discharged in 2018 in the Pharmacy Service.
The safety data sheets were reviewed in the National Institute for Occupational Safety and Health, paying special attention to dangerous identification and exposure controls/individual protection sections. In this database there is not all the information, so we have to use data sheets of our supplier.
We studied Regulation (EU) Nº 1272/2008 on classification, labelling and packaging of substances and mixtures to determined 3 variables: health dangerous, using hazard class like REPR B, MUTA 2 and STORE RE 1; personal protective equipment and installations must be used in handling of our raw materials.
What has been achieved?
We obtained a list of 20 raw materials. 40% of raw materials aren´t considered hazardous.
Of 60% that are classified as hazardous, they were divided into 2 levels: the first, with categories such as serious eye injuries, skin disorders, respiratory tract irritation or toxicity if swallowed; it includes 75% of raw materials. The second level, which includes the rest of products considered hazardous (25%), is associated with 3 categories: REPR B or possible carcinogenicity, that influence the fertility and development of the fetus; MUTA 2 or genetic defects, that are associated with germ cell or mutations; and STORE RE 1 that can cause damage to organs after prolonged or repeated exposure. For 40% of raw materials there are no specific recommendations about using personal protective equipment. With 60% it is recommended to use self-filtering masks for particles, protective gloves and glasses. For 16% of materials, protective clothing against chemicals is required too. In 65% of raw materials, no specific installation is required to handle them. However, for 25% it is recommended to have well-ventilated areas and with 10% a chemical smoke cabin.
What next?
Most of raw materials we use to make magistral formulations are considered hazardous according to Regulation (EU) nª1272/2008. For this reason, we developed a protocol that included individual protection measures and laboratory equipment necessary to handle such raw materials. So it is possible to normalise the preparation of magistral formulations guaranteeing the safety of the area’s staff. We have devised a plan for review and update of the protocol, following current regulations.
HOW TO HANDLE ACTIVE AND PLACEBO DRUGS FOR A CLINICAL TRIAL IN THE PRODUCTION SYSTEM CATO IN ORDER TO SECURE THE BLIND AND TO ENSURE THE EXACT SAME PREPARATION OF ACTIVE AND PLACEBO PRODUCTS

Why was it done?
When preparing treatments for blinded clinical trials it is very important to make sure that it is not possible to distinguish between the active and the placebo dose, as this may lead to unblinding of the treatment and thus jeopardise the results of the trial.
What was done?
The purpose was to find solutions for how to handle active and placebo drugs in the production system CATO to ensure they would end up being identical when prepared.
How was it done?
Before preparing a drug using CATO the drug must be registered in the system with all of its data. It is not possible to have two different sets of data for one drug. CATO records detailed documentation of what is being done during preparation and it is not possible to pretend to pick one drug and then grab another instead. Also, the label is printed automatically so it will show exactly what was prepared. We decide on a common name for the active/placebo and register both of these in the system under that name so that they will be prepared in exactly the same way and appear identical on the label but are still distinguishable in the batch documentation. We name the drug ‘Protocol name Active substance/placebo’ and register the stock of both active drug and the sodium chloride solution that is used as placebo under that name. We will also stock vials of NaCl for this purpose next to the drug it is being placebo for, and NaCl can be prepared pretending it has the density of the drug. CATO will think they are the same drug but they have been registered with their very different batch numbers, maybe with a NaCl after the number of that, so it is always possible to see what was actually being prepared.
What has been achieved?
Our doses of active and placebo are indistinguishable. Labels are the same and, for example, withdrawal into a syringe and insertion of a needle into the port of the infusion bag will be done in the same way.
What next?
These very simple routines can be used anywhere for the preparation with CATO and possibly also with other systems.
