1 Aug Resealed Erythrocytes: Such drug-loaded carrier erythrocytes are prepared simply by collecting blood samples from the organism of interest. Carrier erythrocytes, resealed erythrocytes loaded by a drug or other therapeutic agents, have been exploited extensively in recent years for both temporally and. By using various methods the cells are broken and the drug is entrapped into the erythrocytes, finally they are resealed and the resultant carriers are then called.
