摘要
; The objective of (he study was to evaluate the bitterness, grittiness and uniformity of drug loading as measures of the quality of 12 formultaions of clarithromycin dry syrup (CAMDS), comprising one branded and I I generic products. Some of the generic CAMDS formulations were more bitter than the branded product while others had similar bitterness when tested as aqueous suspensions. Only one generic product was less bitter than the branded product when tested as a suspension in acidic sports drink. The usual dissolution test described in JP XV could not be used to evaluate the bitterness of the products. A brief dissolution test using only 12.5 ml of water was used to evaluate the bitterness of the products in aqueous suspensions. There were considerable variances in the grittiness of the various products, which were independent of particle size. Changes in grittiness level seemed to be correlated with changes in the intensity, of bitterness due to the disintegration of the formulation. Finally. there was less variation in the uniformity of drug, loading for the branded product than for the generic products. These data may be useful when selecting which CAMDS formulation to prescribe.
