Session 7: Dispensing of Pharmaceutical Materials Total Session Time: 120 minutes Pre-requisites • None Learning Tasks By the end of this session students are expected to be able to: • Dispensing of raw materials • Describe dispensing area for raw materials • List equipment used in dispensing of raw materials • Explain the dispensing of raw materials Resources Needed: • Flip charts, marker pens, and masking tape • Black/white board and chalk/whiteboard markers • LCD projector and computer SESSION OVERVIEW |Step |Time |Activity/ |Content | | | |Method | | |1 |05 minutes |Presentation |Introduction, Learning Tasks | |2 |10 minutes |Presentation |Dispensing and Dispensing Area | |3 |20 minutes |Buzzing |Dispensing Equipments | | | |Presentation | | |4 |25 minutes |Presentation |Preparation for Dispensing Raw | | | | |Materials | |5 | |Small group |Dispensing Process for Pharmaceutical| | |40 minutes |discussion |Raw Materials | | | |Presentation | | |6 |05 minutes |Presentation |Key Points | |7 |05 minutes |Presentation |Evaluation | SESSION CONTENTS STEP 1: Presentation of Session Title and Learning Tasks (5 minutes) READ or ASK students to read the learning tasks and clarify ASK students if they have any questions before continuing STEP 2: Dispensing and Dispensing Area (20 minutes) • Dispensing of raw materials is the process whereby raw materials required for production are identified, weighed or measured and transferred to the production area • Every pharmaceutical manufacturing plant must have an area in which raw materials are weighed and transferred in clean containers to the production area • The area where dispensing takes place is known by various names including weighing bay, weighing area, weighing room, central weigh, pharmacy or dispensing room • Features of a weighing room include; o Unidirectional flow of materials and personnel o Segregation between hazardous and non-hazardous materials o Separation of storage and manufacturing items and space • The weighing room is the entry point to manufacturing and the transition point for materials coming from the warehouse and entering processing areas • The dispensing areas is commonly comprised of; o Weighing area ▪ Where actual weighing or measuring of raw materials is done o Raw material staging area ▪ When weighing is complete, there may still be material left in the containers received from the client ▪ Large quantities are usually returned to the warehouse, but small quantities, especially of those materials that will be used again soon, can be stored on pallets or on shelving in raw material staging areas (materials requiring special storage conditions not provided by the raw material staging area are returned to their appropriate storage locations in the warehouse) o Work-in-process STEP 3: Dispensing Equipments (20 minutes) |Activity: Buzzing (5 minutes) | | | |ASK students to pair up and buzz on the following question for 2 | |minutes | | | |Which equipments are used in dispensing of raw materials? | | | |ALLOW few pairs to respond and let other pairs to add on points not | |mentioned | | | |WRITE their response on the flip chart/board | | | |CLARIFY and SUMMARIZE by using the content below | • Dispensing equipment include the following; o Scales ▪ Size of scale used is determined by capacity of materials to be weighed ▪ Example is a pit-mounted floor scale o Pippetes o Calibrated measuring containers o Fume cabinets o Labels/printers and related instrumentation • All equipment must be calibrated and maintained regularly to minimize errors o Routine testing must be carried out for all the balances being used in the facility • All dispensing equipment must be documented properly • There should be SOP for using each equipment STEP 4: Preparation for Dispensing Raw Materials (25 minutes) • Before any dispensing activity is done, the warehouse, in-process quality control and production personnel must ensure that ; o The dispensing area and dispensing equipment are cleaned o Differential pressure, temperature and relative humidity of the dispensing area are within the specified limits o Documents related to previous products are removed from dispensing area o All the log books of the respective areas are updated o Approved materials are to be dispensed o The reverse laminar flow (RLAF) is switched on 15 minutes before dispensing activity starts • Production personnel is responsible for calculating the quantity of active pharmaceutical ingredients (APIs) and excipients (and adjustments according to standard batch size, if applicable) as outlined in the Batch Manufacturing Record (BMR) o The calculations are verified by in-process quality control personnel • Personnel enter the dispensing area through the personnel airlock with proper gowning • Dispensing is only done in controlled conditions under reverse laminar air flow STEP 5: Dispensing Process for Pharmaceutical Raw Materials (40 minutes) |Activity: Small Group Discussion (10 minutes) | | | |DIVIDE students into small manageable groups | | | |ASK students to discuss on the following question | |Explain the dispensing procedures for raw materials? | | | |ALLOW students to discuss for 10 minutes | | | |ALLOW few groups to present and the rest to add points not mentioned| | | | | |CLARIFY and SUMMARIZE by using the contents below | o Receipt of “Dispensing of Raw Material Sheet” ▪ The Batch Manufacturing Record (BMR) contains a list of raw materials to be dispensed known as Dispensing of Raw Material sheet ▪ All raw materials are dispensed as per quantities mentioned in the “dispensing of raw material” sheet of the BMR o Verification of Availability ▪ Warehouse personnel verifies the availability of the approval status of required raw materials ▪ A raw materials stock card of respective raw material is used to facilitate the verification process o Dispensing the raw material ▪ After verification of availability, warehouse
