Carbopol 974p was soaked in distilled water under mechanical stirring. This dispersion was kept overnight for complete hydration of the polymer. SLN Batch F8 (quantity equivalent to 0.1% w/w of MF) was added with stirring to ensure uniform mixing of drug in dispersion. Triethanolamine was slowly added drop by drop to form a fine gel after complete dispersion. Similar procedure was followed for preparation of the plain MF loaded gel
