The invention relates to an orodispersible tablet comprising the components pharmaceutically acceptable sildenafil salt, polymeric adsorbent, in particular cation exchanger resin, sweetener, and flavoring and, preferably, mucilage and glidant. The superconductor can be based on doped AFe2As2, where A can be Ca, Sr, Ba, Eu or combinations thereof for purposes of illustration only. In at least some embodiments the second portion extends into the bore, and a first sealing ring positioned at least partially within the groove surrounding the internal flange recess. The depth from the base of the largest recess to the base of the smallest recess in the smaller size range is less than the depth of the smallest recess in the larger size range.
