Table 4 Analysis of CLM in the presence of common excipients by the proposed assay

From: Novel microwell assay with high throughput and minimum consumption for organic solvents in the charge transfer-based spectrophotometric determination of clarithromycin in pharmaceutical formulations

Excipient Recovery (% ± SD)a
Starch (50)b 97.9 ± 1.54
Microcrystalline cellulose (10) 100.2 ± 0.25
Silica gel (10) 98.5 ± 1.34
Talc (10) 97.4 ± 0.89
Titanium oxide (10) 101.3 ± 1.02
Magnesium stearate (10) 97.2 ± 1.54
Average ± SD 98.8 ± 1.65
  1. aValues are mean of three determinations.
  2. bFigures in parenthesis are the amounts in mg added per 50 mg of CLM.
