Abstract

Transdermal matrices containing 1.258 mg/cm² of propranolol and consisting of ethylcellulose (EC), castor oil, and hydroxypropylmethylcellulose (HPMC) or halloysite (HA) were prepared. They were evaluated by tests such as folding endurance, moisture content and absorption, and paddle dissolution test. Of the total amount of propranolol in the samples (20 mg), 28.41% ± 3.30% was released from the EC film after 24 hours, the addition of HA 20.94% ± 1.52% (f₁ = 61.82 ± 7.70, f₂ = 53.61 ± 4.25) or HPMC 36.05% ± 6.18% (f₁ = 34.48 ± 8.79, f₂ = 65.02 ± 5.33). The dissolution profiles of HA and HPMC films were compared with each other (f₁ = 51.35 ± 12.56, f₂ = 59.20 ± 9.43).
