Drug carrier
From Wikipedia, the free encyclopedia
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.
