The dissolution and the three‐phase partition profiles, vs. time, of diclofenac, alclofenac and their sodium salts have been examined in buffered mediums. The bioavailability of these drugs appears to be mainly controlled by the dissolution. The parameters influencing the higher dissolution rates of the sodium salts relative to the free acids are briefly discussed.
