ABSTRACT

OBJECTIVE:

To optimize Azelastine hydrochloride (AH) thermosensitive in-situ gel nasal drops formulation.

METHODS:

Using poloxamer 407(P407)and poloxamer 188(P188)as excipients,AH thermosensitive in-situ gel was prepared by cold solution method. The formulation was optimized by central composite design-response surface methodology using the amount of P407 and P188(g/100 ml)as factors and phase-transition temperature as index. Binomial expression was fitted,and pre-dicted and measured values were compared.

RESULTS:

The correlation coefficient R2 fitted by binomial expression was equal to 0.986 5. The optimal formulation was as follows as P407 for 20.414 4%,P188 for 5.035 4%,measured value of(30.81±0.02)℃, predicted values of 31 ℃,deviation of 0.61%.

CONCLUSIONS:

AH thermosensitive in-situ gel nasal drops formulation is opti-mized by central composite design-response surface methodology.
