What is imipramine pamoate?
Imipramine pamoate is a salt form of the antidepressant imipramine. It combines imipramine with pamoic acid (pamoate), which can affect how the drug is formulated and absorbed in the body compared with imipramine base or other salt forms. The active medicine responsible for the antidepressant effect is imipramine.
How is it used compared with regular imipramine?
Imipramine pamoate has been used in some settings where a salt form is preferred for a specific formulation. In practice, the clinical use is tied to imipramine’s effects as an older tricyclic antidepressant, but the pamoate form is mainly relevant because it is tied to product formulation and dosing characteristics (rather than representing a different class of drug).
Is it the same thing as imipramine hydrochloride?
No. “Imipramine pamoate” and “imipramine hydrochloride” are different salt forms. They both contain imipramine as the pharmacologically active component, but the counter-ion (pamoate vs. hydrochloride) differs, which can change formulation properties and dosing calculations.
Why do drug salt forms like pamoate matter?
Salt forms can change how a medication is manufactured and how it dissolves and is absorbed. That can affect the drug’s onset and overall exposure from a given product, even though the underlying active drug is still imipramine.
