Abstract
Solid dosage forms are produced by absorbing solutions of drug:cyclodextrin inclusion complexes on absorbing matrices and then drying. The matrices may, but need not, disintegrate in water. The resulting forms are suitable for oral or sublingual administration, and also can be used in topical administrations to mucosa covered tissues. They are particularly suitable for sublingual administration because the eluted, nondisintegrated matrix (e.g., absorbing paper) can be recovered and checked for completion of elution. This enables documentation that effective absorption occurred from the mouth cavity.
