FORMULATION, OPTIMIZATION, AND CHARACTERIZATION OF TRANSDERMAL DRUG DELIVERY SYSTEMS CONTAINING EPLERENONE

Objective: The proposed work was aimed at optimization, formulation, and characterization of transdermal patches of eplerenone for efficient transdermal delivery of the drug.
Methods: The log p estimation of eplerenone is 1.34, it was closer to standard worth. Log P value in a range of 1 to 4 indicates higher permeation through the skin. FTIIR study was carried out individually for drug, each polymer, and finished product (Patches) compared eplerenone and FTIR
spectra of pure drug and polymer. The calibration curve of eplerenone in Phosphate buffer pH 6.8 was analyzed. Results: The selected range of eplerenone was found to be linear. A regression coefficient (R2) at 245 nm was found to be 0.994. Drug content outcomes additionally discovered uniform in all clusters in a range of 97 % to 98 %, that batches arranged with ERS 100 show great mechanical properties contrast with different polymers however helpless glue properties. The flatness of 4 cm2 patches ranges from 348±0.087 mg to
387±0.527 mg. skin irritation it was produced irritation with negligible erythema following 10 d and unequivocal erythema, promptly obvious edema was produced following 12 d.
