The invention discloses high-efficiency environment-friendly clotting cat litter. The high-efficiency environment-friendly clotting cat litter comprises, by weight, 70%-80% of wood bits, 10%-20% of corn husk powder, 5%-8% of sodium carboxymethyl starch, 1%-3% of vegetable oil, 1%-3% of sodium bicarbonate and 5%-8% of xanthan gum; the high-efficiency environment-friendly clotting cat litter is prepared through grinding, prilling, airing, sizing and packaging. The cat litter is an object which is 3 mm-6 mm in grain size and 6 mm-12 mm in length, the surface and the interior of the cat litter are provided with alveolate micropores, the specific gravity is small, the void ratio is high, a large amount of cat urine and shit can be absorbed and stored, particles rapidly swell and collapse after the cat urine and shit are absorbed to form blocks, and the blocks are clotted to be in a flocculent shape, so that smells of the absorbed cat urine and shit are not prone to being discharged from the interiors of the particles; as the flocculent-shaped blocks in a cat litter disc are removed through a shit shovel, the cat litter left in the cat litter disc and the blocks needing to be removed can be separated while the aim of removing the cat urine and shit in time is achieved, the un-clotted cat litter cannot be removed, and the cat litter using rate is improved.

The invention provides an Erdosteine composition which consists of the following components by weight portions: 130 to 170 portions of Erdosteine, 35 to 65 portions of lactose, 30 to 70 portions of microcrystalline cellulose, 20 to 40 portions of low substituted hydroxypropyl cellulose, 1 to 5 portions of acesulfame, 10 to 30 portions of sodium carboxymethyl starch and 0.1 to 0.5 portions of magnesium stearate; the invention also provides a preparation method of the Erdosteine composition, comprising the following steps of: preparing materials and pelleting; mixing the Erdosteine and the low substituted hydroxypropyl cellulose evenly, then grinding, adding the sodium carboxymethyl starch, adding absolute ethyl alcohol, wet-mixing, cutting, drying, granulation and tabletting; mixing granules and microcrystalline cellulose evenly, adding the lactose, the acesulfame and the magnesium stearate for pelleting, subpackaging and obtaining the Erdosteine composition. The Erdosteine compositionhas good dispersible uniformity and high drug dissolution efficiency.
