Drug carrier

Drug carriers are substances that serve as mechanisms to improve the delivery and the effectiveness of drugs. Drug carriers are used in sundry drug delivery systems such as:

• controlled-release technology to prolong in vivo drug actions;
• decrease drug metabolism, and
• reduce drug toxicity.

Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions.

Examples

Carriers which are able to biodegrade include:

• Liposomes;
• Microspheres made of the biodegradable polymer poly(lactic-co-glycolic) acid
• albumin microspheres;
• synthetic polymers (soluble);
• Protein-DNA complexes;
• protein conjugates; and
• erythrocytes.
