Süstendiga

Süstendiga is a term used in Estonian medical language to indicate that a substance is administered by injection. The word is formed from the noun for injection and a comitative suffix, yielding a form that functions as an adjective or adverb meaning “with an injection” or “by injection.” In practice, süstendiga appears in phrases describing routes of administration, such as medicines or procedures.

In its typical use, süstendiga describes how something is given rather than what it is. For example, a drug can be described as “süstendiga manustatav ravim” (a drug administered by injection) or in a clause like “Ravim manustatakse süstendiga” (The drug is administered by injection). The term is commonly encountered in medical notes, patient information leaflets, and pharmaceutical labeling to contrast injectable forms with alternative routes such as oral or topical administration.

Etymologically, süstendiga is linked to the Estonian word for injection and employs the comitative mechanism to convey “with” or “by means of,” a usage pattern that is familiar in medical and procedural language. While it is widely understood within Estonian healthcare contexts, süstendiga is not a standalone noun and is less likely to be used outside professional or clinical writing. In English, the closest equivalents are typically “by injection” or “injectable,” depending on whether the emphasis is on the method of administration or the form of the medication.
