trituration and levigation trituration is grinding the powder into finer particles in a mortar & pestle levigation is like trituration except a wetting gent or levigating agent is used to help with the grinding process
37
what is spatulation?
When a spatula is used instead of a pestle in a mortar
38
what is geometric dilution?
when a small amount of drug is mixed with equal parts of other ingredients. Once this is mixed then another small amount of drug is mixed with equal amounts of other ingredients. This is to make a uniform product. Akin to adding dry to wet in small amounts to prevent lumps in baking.
39
where should the compounding ingredients come from?
preferable from a FDA registered facility. If it is not from a FDA registered facility, then a certificate of analysis (CoA) should be obtained.
40
What should the pharmacist do if a compounding component does not have an expiration date?
the pharmacist must write on the container the date of receipt (arrival to pharmacy) and the conservative approach which is up to 3 years expiration date from the date of receipt.
