ALLOW few students to respond? WRITE their responses on the flip chart/ board CLARIFY and SUMMARISE by using the content below • The term “Powder” when used in the context of dosage form, describes a formulation in which a drug powder has normally been mixed with other powdered excipients to produce a final product. o Therefore Powders for oral Preparations are mixtures of finely divided solids intended for oral administration and comprise of the active ingredients plus excipients (such as diluents, sweeteners, and dispersing agents) where necessary. o They are usually mixed with water or other suitable liquid before administration. • Granules that are used as a dosage form comprise powder particles that have been aggregated to form larger particles sufficiently robust to withstand handling. • Granules are obtained by granulation, where by dry primary powder particles are (i.e. single, discrete powder particles) are processed to adhere to form larger multi-particle entities. CMT 04101 Dispensing NTA L 4 Semester 1 Facilitator Guide Session X: ———— -(Title)———————- 73 STEP 3: Reconstitution of Powders/ Granules for Oral Preparations (10 Minutes) Activity: Buzzing (5 minutes) ASK students to pair up and buzz on the following question for 2 minutes • What is medicine reconstitution? 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 • Reconstitution refers to the process of adding a diluent to a dry ingredient to make it a liquid. o Therefore medicine reconstitution refers to use the given directions, or recipe, on a prescription label to mix the powder contained inside to a specific concentration as indicated. • Diluent is the liquid used to mix a medication during reconstitution, different medications use different diluents so be sure to read the medication label or package insert correctly so that you use the proper diluent and volume needed to reconstitute the medication. o If the correct diluent is not used, the medication may clump or crystallize making it unusable for administration o Examples of common diluent used in reconstitution of oral powders/granules are, purified water, syrup, normal saline (NS 0.9%), dextrose 5% in water (D5W). • The volume of diluents that should be added to a powder or granules to produce a specific volume of a final product with the required concentration varies between formulations. • Therefore before reconstituting any powdered/granulated medication it is important to read manufacturer‟s instructions (package inset), so as to know exactly which diluent to be used and the amount of diluent to be added in order to produce the required concentration. • If a large amount of diluent is to be added to the bottle, a portion of the diluent (usually half) should be added to medication and then mixed. Once the medication as started to dissolve, the second portion of diluent is added and mixed. Be sure the medication has dissolved completely before administering to the patient. • Example of the instruction for reconstitution are shown on figure 11.1 and figure 11.2 CMT 04101 Dispensing NTA L 4 Semester 1 Facilitator Guide Session X: ———— -(Title)———————- 74 • Figure 11.1: Instruction for Reconstitution of Amoxicillin Suspension • Source: Reconstituting medicine handout (2013).

STEP 2: Labelling of Prepared Preparations (35 minutes) • Label means any tag, brand, mark, pictorial or other descriptive matter, written, printed, stencilled, marked, embossed or impressed on or attached to a container of any food, drug, cosmetics or medical devices o A label is an important, integral part of a drug preparation o A label gives clear instructions on how and when to take or use the medication o The label contributes a good appearance of dispensed medicine, thus increasing the confidence of the patient o The label should be written in a legible, neat, and well balanced way o The size of the label should be appropriate to that of the container • The main label should clearly state the following: o The name (underlined) and quantity of the preparation o The patient‟s name o The date of dispensing (preparation date) o Dose and instruction for use. o The expiry date, where applicable and/ or manufacturing date o Storage condition o The name of the dispenser (initial) o The name and address of the dispensing institution. o Required dispensing information, such as Shake well before use. • Preparations intended for application to the skin should be labelled “for External Use Only” in red; those to be used in the mouth but not to be swallowed, get an auxiliary label “Not to be Swallowed”. “Not to be Taken” is used for liquid preparations which are not administered orally and which are not applied to skin surfaces such as ear drops, eye- drops, nasal drops, enemas and for solid dosage forms which might, by error, be administered orally such as inhalation capsules, pessaries and solution tablets. Alternatively, such preparations can be labelled with instructions on the restricted use e.g. “For Use in the Eye Only” or “Rectal Use only” or “For Vaginal Use Only”. All heterogeneous liquid preparations such as emulsion and suspensions, must carry the instruction “Shake before use”. Special storage conditions are also given on the auxiliary label such as “Store at a Cool Place” or more precise instructions like “Store between 20 C and 80C”. Preparations containing easily inflammable liquids are labelled “Highly Inflammable” or “Keep away from Open Flames” • All dispensed medicines should have the instruction: “Keep out of Reach of Children”. • A label have the following important characteristics o Neat (orderly and in a clean condition) o Clear (easily deliver a well-defined message in a simple language) CMT 04101 Dispensing NTA L 4 Semester 1 Facilitator Guide Session X: ———— -(Title)———————- 83 o Fit the container (not too large or too small) o Attractive (pleasing or appealing to the senses) Activity: Demonstration (25 minutes) DIVIDE students in small manageable groups.

DEMONSTRATE on how to write a good label ALLOW one student from each group to do a return demonstration and let others comment on it CLARIFY and SUMMARIZE by using the content below INFORM the students that “every student will practice in the skills laboratory under supervision until is competent” • Example of labels: For External Use Only CALAMINE LOTION PCx 100 mL Apply to the affected parts at night until cured. The name of the dispenser and the name and address of the dispensing Institution Preparation date Expiry date SHAKE THE BOTTLE BEFORE USE Keep Out of Reach of Children CMT 04101 Dispensing NTA L 4 Semester 1 Facilitator Guide Session X: ———— -(Title)———————- 84 STEP 3: Dispensing of Prepared Preparations into Suitable Containers (10 minutes) • Selection of a suitable container is more crucial, because container forms an integral part of dispensed medicines and should maintain the quality, safety and stability of its contents. Therefore it should comply with the following requirement: o Be strong enough to protect the contents from normal mechanical hazards of handling and transport. o Prevent leakage o Provide protection from environmental conditions, such as moisture, microorganisms, oxygen, carbon dioxide and light. o Be sufficiently transparent to inspect liquid preparation. o Do not react with the contents. • Some general guidelines on selection of container for preparations made in small scale compounding are: o Liquid medicines. Preparations for external use, for application to the mouth and throat, and for instillation into body cavities should be dispensed in fluted bottles, whereas those for internal use should be dispensed in plain bottles, as officially recommended. o This difference gives warning to user of the medicine. When someone touches a bottle which is fluted will be cautioned that the medicine should not be swallowed. Even though this is not more practicable now a days. o Medicines which

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 • Mixture refers to a combination of two or more substances with or without chemical union. (Synonym: Mistura ) • Mixtures is often referred both oral solutions and suspension. • A solution is a homogeneous liquid preparation that contains one or more dissolved medicaments. Since, by definition, active ingredients are dissolved within the vehicle, uniform doses by volume may be obtained without any need to shake the formulation. • A suspension is a heterogeneous mixture of a solid and a liquid in which the solid does not dissolve. OR • A suspension is a two-phase system comprising solid particles (the disperse phase) dispersed in a liquid (the continuous phase or dispersion medium) • General procedures for preparation of solutions: o Write out the formula either from the prescription (unofficial) or from an official text (official). o Calculate the quantities required for each ingredient in the formula to produce the required final volume. o Prepare a suitable label. o Weigh all solids in case of liquid to liquid solution measure the accurate volumes required. o Identify the soluble solids and calculate the quantity of vehicle required to dissolve the solids fully. If more than one solid is to be dissolved, they are dissolved one by one, in order of solubility (i.e. the least soluble first). CMT 04101 Dispensing NTA L 4 Semester 1 Facilitator Guide Session X: ———— -(Title)———————- 90 o Transfer the appropriate amount of vehicle to a glass beaker. o If necessary, transfer the solid to a mortar and use the pestle to reduce particle size to aid dissolution o Transfer the solid to the beaker and stir to aid dissolution. If a mortar and pestle have been used to reduce particle size, ensure that the mortar is rinsed with a little vehicle to ensure complete transfer of the powders. o When all the solid(s) has/have dissolved, transfer the solution to the conical measure that will be used to hold the final solution. o Rinse out the beaker in which the solution was made with a portion of the vehicle and transfer the rinsing to the conical measure. o Add any remaining liquid ingredients to the conical measure and stir. o Make up to final volume with remaining vehicle. o Transfer to a suitable container, label and dispense to the patient. • General procedure for preparation of solid in liquid mixtures (Suspensions) o Write out the formula either from the prescription (unofficial) or from an official text (official). o Calculate the quantities required for each ingredient in the formula to produce the required final volume. o Prepare a suitable label. o Weigh all solids and measure the accurate volumes of the liquids required. o The solids, if necessary, are reduced to a fine powder in a mortar and mixed thoroughly mixed with any included suspending agents. o The small proportion of the vehicle is added and triturated until a smooth creamy paste free from lumps is formed. o If there are soluble solids, they are dissolved in the vehicle and the solution is added in portions to the mortar and the mixture is triturated to a smooth consistency after each addition. o Then the mixture is transferred to conical measure. o The vehicle is used to rinse the mortar and make up to final volume. o Then transferred to suitable container, label and ready for dispensing to a patient.

Session 16: Procedures for preparing Specialized food products used in Tanzania …………………………………………………………………………………………………..109 PST 04101 Dispensing NTA Level 4 Semester 1 Facilitator Guide iii Background There is currently an ever increasing demand for pharmaceutical personnel in Tanzania. This is due to expanding investment in public and private pharmaceutical sector. Shortage of trained pharmaceutical human resource contributes to poor quality of pharmaceutical services and low access to medicines in the country (GIZ, 2012). Through Public-Private-Partnership (PPP) the Pharmacy Council (PC) together with Development Partners (DPs) in Germany and Pharmaceutical Training Institutions (PTIs) worked together to address the shortage of human resource for pharmacy by designing a project named “Supporting Training Institutions for Improved Pharmaceutical Services in Tanzania” in order to improve quality and capacity of PTIs in training, particularly of lower cadre pharmaceutical personnel. The Pharmacy Council formed a Steering committee that conducted a stakeholder‟s workshop from18th to 22ndAugust 2014 in Morogoro to initiate the implementation of the project. Key activities in the implementation of this project included carrying out situational analysis, curriculum review and harmonization, development of training manual/facilitators guide, development of assessment plan, training of trainers and supportive supervision. After the curricula were reviewed and harmonized, the process of developing standardised training materials was started in August 2015 through Writer‟s Workshop (WW) approach. The approach included two workshops (of two weeks each) for developing draft documents and a one-week workshop for reviewing, editing and formatting the sessions of the modules. The goals of Writers Workshops were to build capacity of tutors in the development of training materials and to develop high-quality, standardized teaching materials. The training package for pharmacy cadres includes a Facilitator Guide, Assessment plan and Practicum. There are 12 modules for NTA level 4 making 12 Facilitator guides and one Practicum guide. PST 04101 Dispensing NTA Level 4 Semester 1 Facilitator Guide iv Acknowledgement The development of standardized training materials of a competence-based curriculum for pharmaceutical sciences has been accomplished through involvement of different stakeholders. Special thanks go to the Pharmacy Council for spearheading the harmonization of training materials in the pharmacy after noticing that training institutions in Tanzania were using different curricula and train their students differently. I would also like to extend my gratitude to St. Luke Foundation (SLF)/Kilimanjaro School of Pharmacy –Moshi for their tireless efforts to mobilize funds from development partners. Special thanks to John Snow Inc (JSI), Deutsche Gesellschaft Für Internationale Zusammenarbeit (Giz), Merck Kgaa, Boehringer Ingelheim Gmbh and Bayer Pharma Ag and action medeor.V for the financial and technical support. Particular thanks are due to those who led this important process to its completion, Mrs Stella M. Mpanda Director, Childbirth Survival International, and Members from the secretariat of National Council for Technical Education (NACTE) for facilitating the process. Finally, I very much appreciate the contributions of the tutors and content experts representing PTIs, hospitals, and other health training institutions. Their participation in meetings and workshops, and their input in the development of this training manual/facilitators guide have been invaluable.
