\n(2) Toz Kaplama Katmanlar\u0131nda Kullan\u0131m\u0131
\n\u015eeker kaplama s\u00fcrecinde talk tozu, toz kaplama katman\u0131n\u0131 olu\u015fturmak amac\u0131yla kullan\u0131l\u0131r. Genellikle %3 ila %6’l\u0131k bir konsantrasyonda olmak \u00fczere, 100-mesh’lik bir elekten ge\u00e7irilmi\u015f beyaz talk tozunun kullan\u0131lmas\u0131 \u00f6nerilir. Bu uygulama, yaln\u0131zca keskin kenarlar\u0131 yumu\u015fatarak kaplama s\u00fcrecini kolayla\u015ft\u0131rmakla kalmaz, ayn\u0131 zamanda \u015feker kapl\u0131 tabletlerin stabilitesini de art\u0131r\u0131r. Toz kaplama a\u015famas\u0131ndan \u015feker kaplama a\u015famas\u0131na ge\u00e7i\u015f s\u0131ras\u0131nda, kullan\u0131lan talk tozu ve \u015furup oranlar\u0131na azami dikkat g\u00f6sterilmeli; talk tozu miktar\u0131 kademeli olarak azalt\u0131lmal\u0131d\u0131r.

\nG\u00fcn\u00fcm\u00fczde talk tozu; da\u011f\u0131labilir tabletler, kaps\u00fcller, \u00e7i\u011fnenebilir tabletler, efervesan tabletler ve kontroll\u00fc sal\u0131ml\u0131 tabletlerin form\u00fclasyonlar\u0131nda kayd\u0131r\u0131c\u0131 madde olarak s\u0131kl\u0131kla kullan\u0131lmaktad\u0131r. \u0130la\u00e7 tozu par\u00e7ac\u0131klar\u0131n\u0131n y\u00fczeyindeki d\u00fczensizlikleri ve \u00e7ukurlar\u0131 doldurarak talk tozu, par\u00e7ac\u0131klar aras\u0131 s\u00fcrt\u00fcnmeyi etkili bir \u015fekilde azalt\u0131r ve toz kar\u0131\u015f\u0131m\u0131n\u0131n ak\u0131\u015fkanl\u0131\u011f\u0131n\u0131 iyile\u015ftirir. Kayd\u0131r\u0131c\u0131 olarak kullan\u0131ld\u0131\u011f\u0131nda talk tozunun tipik konsantrasyonu %0,1 ila %3 aral\u0131\u011f\u0131nda de\u011fi\u015fir ve genellikle %5’i a\u015fmamal\u0131d\u0131r.
\n(4) Filtrasyon Yard\u0131mc\u0131s\u0131 Olarak Kullan\u0131m\u0131
\nTalk tozu kimyasal olarak inert (t\u0131bbi maddelerle reaksiyona girme olas\u0131l\u0131\u011f\u0131 d\u00fc\u015f\u00fck) oldu\u011fu ve belirli bir d\u00fczeyde adsorpsiyon kapasitesine sahip bulundu\u011fu i\u00e7in, filtrasyon yard\u0131mc\u0131s\u0131 olarak i\u015flev g\u00f6rebilir. 115\u00b0C’de \u0131s\u0131t\u0131larak aktive edilmi\u015f talk pudras\u0131\u2014hen\u00fcz s\u0131cakken t\u0131bbi bir s\u0131v\u0131ya eklendi\u011finde\u2014ilac\u0131n kendi etken maddelerine \u00f6nemli \u00f6l\u00e7\u00fcde zarar vermeksizin; polisakkaritler, m\u00fcsilaj ve sak\u0131zlar gibi k\u00fc\u00e7\u00fck miktardaki safs\u0131zl\u0131klar\u0131 adsorbe edebilir. Bununla birlikte, talk pudras\u0131n\u0131n son derece ince par\u00e7ac\u0131k boyutuna sahip olmas\u0131 nedeniyle, sonraki filtreleme s\u00fcrecini bazen daha zorlu hale getirebilece\u011fi unutulmamal\u0131d\u0131r.<\/p>\n

Talk Pudras\u0131n\u0131n Farmas\u00f6tik Yard\u0131mc\u0131 Madde (Eksipiyan) Olarak Kullan\u0131m Alanlar\u0131<\/p>\n

(1) Hidrofobik \u0130la\u00e7lar \u0130\u00e7in Da\u011f\u0131t\u0131c\u0131 (Disintegran) Olarak Kullan\u0131m\u0131<\/p>\n
