Encyclopedia entry (1928–1936)
LAMBLIA INTESTINALIS, see Giardia intestinalis. LAMELLAE (lamellae), a medicinal form in the form of thin plates. A gelatin mass (18% gelatin, 2% glycerin) with an admixture of medicinal substance (e.g., 1% atropine sulfate or 10-40% cocaine hydrochloride) is poured onto glass plates previously coated with a thin layer of wax; after solidification, circles weighing 1-5 mg are cut from the mass. This form allows for more precise dosing of minimal amounts of alkaloids than is possible in drops (e.g., eye drops),
for which reason it was introduced into the Swiss and British pharmacopoeias under the name 'gelatin disks' (lamellae), and into the Italian pharmacopoeia as 'gelatinae medicatae in lamellis.' When introduced with tweezers onto the cornea of the eye, 1-2 lamellae, the gelatin mass dissolves, releasing the medicinal substance contained in it. In the USSR, L. are not produced.
