abstract

background it has been shown that topical nanoliposomal formulations improve burn healing process. on the other hand, it has been shown that liposomal formulations increase drug deposition in the normal skin while decrease their systemic absorption there is not such data available for burn eschar. present investigation studies permeation of clindamycin phosphate (cp) through burn eschar from liposomal formulations to answer this question. in this investigation, permeation of cp through fully hydrated third-degree burn eschar was evaluated using solution, normal nanoliposomes and ultradeformable nanoliposomes. methods liposomal cp were prepared by thin-film hydration and characterized in terms of size, size distribution, zeta potential, encapsulation efficiency and short-time stability. then the effect of liposomal lipid concentration on cp absorption was investigated. results the permeability coefficient ratio (liposome/solution) and permeation lag-time ratio (liposome/solution) of cp through burn eschar at 20 mm lipid concentration were 0.81±0.21 and 1.19±1.30 respectively, indicating the retardation effects of liposomes. data also showed that increasing liposomal lipid concentration from 20 to 100 mm, clindamycin permeation decreased by about 2 times. there was no difference between normal liposome and ultradeformable liposome in terms of clindamycin absorption. conclusion nanoliposomes could decrease trans-eschar absorption of cp, in good agreement with normal skin data, and might indicate cp deposition in the eschar tissue.

Enhancement Effect of Trypsin on Permeation of Clindamycin Phosphate Through Third-degree Burn Eschar

Antimicrobial therapy remains to be the most important method of wound infection treatment. Systemically administered antimicrobials may not achieve therapeutic level in wound. On the other hand, in the absence of surgical debridement (due to any reason), most topically applied antimicrobials cannot penetrate the wound in therapeutic amount due to the presence of eschar. Burn eschar is a protei...
