TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compounds: The buffer pair of weak organic acid and its conjugate base is citric acid-sodium citrate, tartaric acid-sodium tartrate, malic acid-sodium malate, and/or acetic acid-sodium acetate. The buffer pair of weak organic acid and weak alkali salt is citric acid-disodium hydrogen phosphate, citric acid-sodium dihydrogen phosphate, tartaric acid-disodium hydrogen phosphate, and/or tartaric acid-sodium dihydrogen phosphate. The ratio of weak organic acid and its conjugate base is 5:1-15:1. The ratio of weak organic acid and weak alkali salt is 7:1-14:1. The pH of acidifying agent is 2-3.5 when in the form of 0.5-20 %mass aqueous solution. The stabilizer optionally contains an antioxidant chosen from L-cysteine, sodium ascorbate, t-butylhydroxy anisole, dibutylhydroxy toluene, t-butylhydroquinone, ascorbyl palmitate, and propyl gallate. The filling agent is mannitol, D-sorbitol, xylitol, lactose, starch, and/or pregelatinized starch, preferably water-soluble mannitol, D-sorbitol, xylitol and/or lactose. The additives further comprise lubricant, disintegrating agent, and/or binder. The lubricant is stearic acid, talc, silica powder, and/or sodium stearyl fumarate. The solvent used in wet granulation is water and/or ethanol.    TECHNOLOGY FOCUS - PHARMACEUTICALS - Preferred Composition: Rasagiline composition comprises 0.1-0.8 wt.% acidifying agent, 0.1-0.8 wt.% stabilizer, 0.7-2.5 wt.% rasagiline salt, 87-98 wt.% filling agent, 0.9-4 wt.% disintegrating agent, 1.7-3 wt.% lubricant, 0.3-2.5 wt.% binder, and water-soluble carrier chosen from polyethylene glycol, povidone, cyclodextrin, and sucrose. The content of carrier is 1.9-6.4 times the weight of rasagiline salt. The composition is obtained by wet-granulating rasagiline salt and stabilizer dissolved in a solvent, adding carrier and/or filling agent, adding the remaining component of carrier and filling agent, adding the remaining additives, and granulating.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The disintegrating agent is sodium carboxymethyl starch, hydroxypropyl cellulose, crosslinked povidone, and/or crosslinked sodium carboxymethyl cellulose. The binder is povidone, hypromellose, methyl cellulose, and/or starch.
