Azelastine hydrochloride displayed no sensitising potential in the guinea pig. Azelastine demonstrated no genotoxic potential in a battery of in vitro and in vivo tests, nor any carcinogenic potential in rats or mice. In male and female rats, azelastine at oral doses greater than 3 mg/kg/day caused a dose-related decrease in the fertility index; no substance-related alterations were found in the reproductive organs of males or females during chronic toxicity studies, however, embryotoxic and teratogenic effects in rats, mice and rabbits occurred only at maternal toxic doses (for example, skeletal malformations were observed in rats and mice at doses of mg/kg/day).

Single dose intranasal administration of 220 micrograms of Nasacort Allergy or Triamcinolone Nasal Spray in normal adult subjects and in adult patients with allergic rhinitis demonstrated minimal absorption of triamcinolone acetonide. The mean peak plasma concentration was approximately ng/mL (range to 1 ng/mL) and occurred at hours post dose. The mean plasma drug concentration was less than ng/mL at 12 hours and below the assay detection limit at 24 hours. The average terminal half life was hours. Dose proportionality was demonstrated in normal subjects and in patients following a single intranasal dose of 110 micrograms or 220 micrograms Nasacort Allergy or Triamcinolone Nasal Spray. Following multiple doses in paediatric patients, plasma drug concentrations, AUC, C max and T max were similar to those values observed in adult patients.
