Drug carriers are also used to improve the pharmacokinetic properties, specifically the bioavailability, of many drugs with poor water solubility and/or membrane permeability. A wide variety of drug carrier systems have been developed and studied, each of which has unique advantages and disadvantages. Some of the more popular types of drug ...
Although unaffected by the pathogen, carriers can transmit it to others or develop symptoms in later stages of the disease. Asymptomatic carriers play a critical role in the transmission of common infectious diseases such as typhoid, HIV, C. difficile, influenzas, cholera, tuberculosis, and COVID-19, [2] although the latter is often associated ...
For example, several types of microneedle patches have been developed for administering vaccines and other medications to reduce the risk of needlestick injury. [4] [8] Drug delivery is a concept heavily integrated with dosage form and route of administration, the latter sometimes being considered part of the definition. [9]
Lipid-based carriers include both liposomes and micelles. Examples of gold nanoparticles are gold nanoshells and nanocages. [3] Different types of nanomaterial being used in nanocarriers allows for hydrophobic and hydrophilic drugs to be delivered throughout the body. [5]
The Use of liposome as carrier enhances the overall permeability of topical drug into the skin to reach the target site. [15] [17] For example, a drug like amphotericin B, is used to treat fungal infections. [18] The drug is loaded into liposome and this carrier enhances the penetration of amphotericin B into the skin, regardless of its ...
There are different types of drug delivery vehicles, such as polymeric micelles, liposomes, lipoprotein-based drug carriers, nano-particle drug carriers, dendrimers, etc. An ideal drug delivery vehicle must be non-toxic, biocompatible, non-immunogenic, biodegradable, [5] and must avoid recognition by the host's defense mechanisms [3].
Among these, many have been characterized and shown to be causally related to diseases present in humans such as cystic fibrosis, adrenoleukodystrophy, Stargardt disease, drug-resistant tumors, Dubin–Johnson syndrome, Byler's disease, progressive familiar intrahepatic cholestasis, X-linked sideroblastic anemia, ataxia, and persistent and ...
The two main types of proteins involved in such transport are broadly categorized as either channels or carriers (a.k.a. transporters, or permeases). Examples of channel/carrier proteins include the GLUT 1 uniporter, sodium channels, and potassium channels.
