Case Choice: Genitive or Accusative?
The main rule of pharmaceutical Latin when drafting prescriptions: after the word Recipe (Take), the name of the medicinal substance or plant is put in the genitive case (Genitivus) if its quantity in grams or milliliters is specified in the prescription. This logically answers the question "take of what?". For example, if we translate the task "Take: Validol 0.05", the word "validol" (Validolum — neuter gender, second declension) takes the ending -i: Recipe: Validoli 0.05. The same applies to liquid forms: the phrase "Dimexide solution 100 ml" is translated as Recipe: Solutionis Dimexidi 100 ml, since the word Solutio belongs to the third declension.
However, the grammar changes if the physician needs to prescribe a finished dosage form indicating a specific number of pieces (e.g., tablets, dragees, or suppositories) rather than the weight of the substance per single dose. In this case, the dosage form itself is put in the accusative case (Accusativus). For example, in the prescription "Dexamethasone tablets 0.005 number 50", the word "tablets" will be translated in the accusative plural (Tabulettas), while the name of the active substance itself remains in the genitive (Dexamethasoni).
Verbs in Prescriptions: Moods and Voices
In standard prescriptions, actions for the pharmacist (mix, dispense, label) can be expressed in two grammatical ways. The choice depends on the traditions of drafting a particular prescription.
- Imperative Mood. These are direct commands to the pharmacy worker: Misce (Mix), Da (Dispense), Signa (Label). For example, in a prescription for sulfadimezine tablets or motherwort tincture, the standard ending will sound short and clear: Da. Signa.
- Subjunctive Mood in the Passive Voice. This is a softer, passive formulation: "Let it be dispensed, let it be labeled". In Latin, this sounds like Detur, Signetur, and if the components need to be mixed beforehand, Misceatur is added. When translating orders for such drugs as Revit dragees or senna extract tablets, this construction is often used: Detur. Signetur.
In addition, the subjunctive mood is used in the construction fiat (let it be made). It is necessary when the pharmacist must create a new dosage form from several ingredients. For example: Misce, fiat pulvis (Mix, let a powder be made) or Misce, fiat species (Mix, let a tea/species be made).
Features of Translating Herbal Teas and Complex Powders
If a prescription includes several components in equal doses, the Latin translation requires the mandatory use of the preposition ana (in equal parts, often abbreviated as aa in prescriptions). For example, if it is necessary to take buckthorn bark (Corticis Frangulae) and nettle leaves (Foliorum Urticae) 15.0 grams each, the word ana is placed before the number that applies to both components: ...ana 15.0.
Multi-component herbal prescriptions require precise knowledge of the dictionary forms of plants and the names of their parts. When translating, one must remember that:
- Bark is Cortex, icis m (third declension).
- Leaf is Folium, i n (in the plural — Foliorum).
- Rhizome is Rhizoma, atis n.
- Root is Radix, icis f.
For example, when prescribing an herbal tea with peppermint leaves (Foliorum Menthae piperitae) and valerian rhizome with roots (Rhizomatis cum radicibus Valerianae), one must carefully monitor the case endings of each word.
In complex powders, for example, containing euphylline (Euphyllini), diphenhydramine (Dimedroli), and sugar (Sacchari), the phrase "Dispense such doses in the number of..." is often found. When translated, it is formatted using the accusative plural — Da tales doses numero...
Trade Names and Adjective Agreement
When translating prescriptions that include adjectives, such as "Liquid hawthorn extract", it is important to follow the rule of grammatical agreement. The adjective "liquid" (fluidus) must agree in gender, number, and case with the noun "extract" (Extractum), and not with the plant name (Crataegus). In the genitive singular, this construction sounds like Extracti Crataegi fluidi.
Finished commercial drugs whose names are written in quotation marks require special attention. In prescriptions for forms such as Revit dragees or Anuzol suppositories, the trade name does not decline. It is always capitalized and remains in the nominative case: Dragee "Revit", Suppositoria "Anuzolum". Only the name of the dosage form itself declines.
Briefly: answers to topical questions
How to translate the phrase "Mix, let a suppository be made" into Latin?
The phrase "Mix, let a suppository be made" is translated into Latin as Misce, fiat suppositorium. The use of an abbreviated recording variant — M.f. suppositorium — is also permitted in prescription formulas. A similar grammatical construction is used for other dosage forms:
- Powder (Misce, fiat pulvis) — mix, let a powder be made.
- Ointment (Misce, fiat unguentum) — mix, let an ointment be made.
- Paste (Misce, fiat pasta) — mix, let a paste be made.
How are the names of chemical elements and oxides translated into Latin in prescriptions?
Oxide names in Latin consist of two words. The name of the chemical element in the genitive singular is written first, acting as an non-agreeing modifier. The declinable group name (oxydum, peroxydum, or hydroxydum) is indicated in second place.
| Formula | Latin name | Russian name |
|---|---|---|
| ZnO | Zinci oxydum | zinc oxide |
| H₂O₂ | Hydrogenii peroxydum | hydrogen peroxide |
| Al(OH)₃ | Aluminii hydroxydum | aluminum hydroxide |
Remember the case rule: if the weight or volume of the drug is indicated in the prescription, we write the substance in the Genitive case (Genitivus). If there is the word "number" (numero) for a finished form (tablets, suppositories), we write the form in the Accusative (Accusativus).
Class and exam questions
In which case is the name of the dosage form written if the number of pieces is indicated?
In the accusative case (Accusativus). For example, if we are prescribing tablets, we write Tabulettas.
How to correctly translate the phrase "Dispense such doses"?
In Latin, this phrase is translated as Da tales doses — the accusative plural is used here.
Does the name of a drug written in quotation marks change by cases?
No, commercial names in quotation marks, such as "Revit" or "Anuzolum", do not decline and remain in the nominative case.
How to translate "Let it be dispensed, let it be labeled"?
The subjunctive mood of the passive voice is used for this: Detur. Signetur.
