Sublingual and troche forms
Where a compounded drug parts company with an FDA-approved one, where 503A parts company with 503B, and which accreditation programs tell them apart.
Definition
Compounded preparations dissolved under the tongue rather than injected or swallowed. Marketed as needle-free. ⚠ No sublingual semaglutide or tirzepatide has an FDA-approved counterpart, so there is no bioavailability standard to compare against — the dose that reaches your bloodstream is not an established quantity.
