Summary
Drug transporters in the intestine, liver, and kidney significantly impact drug effectiveness. Understanding transporter-mediated drug interactions is crucial for safe and effective medication use.
Area of Science:
- Pharmacology
- Drug Metabolism and Transport
Background:
- Drug-drug interactions (DDIs) pose a significant clinical challenge.
- Drug transporters mediate xenobiotic uptake and efflux, influencing drug pharmacokinetics.
- Intestinal, hepatic, and renal transporters are key determinants of drug disposition and clinical effects.
Purpose of the Study:
- To elucidate mechanisms of DDIs involving major drug transporters.
- To highlight the role of intestinal, hepatic, and renal transporters in DDIs.
- To discuss genotype-dependent DDIs.
Main Methods:
- Focus on probe drugs with minimal metabolism to isolate transporter interactions.
- Investigated interactions of specific transporters including OATP, P-gp, OAT, BCRP, OCT2, and MATE1.
- Considered the influence of genetic variations on drug-transporter interactions.
Main Results:
- Transporter-mediated DDIs in the small intestine, liver, and kidney can substantially alter drug pharmacokinetics and efficacy.
- Specific transporters like OATP1A2, OATP2B1, OATP1B1, OATP1B3, P-gp, OAT1, OAT3, BCRP, OCT2, and MATE1 are implicated in DDIs.
- Genotype-dependent interactions can modify the impact of DDIs.
Conclusions:
- Drug transporters are critical mediators of DDIs, affecting drug pharmacokinetics and clinical outcomes.
- Understanding transporter mechanisms and genetic variations is essential for predicting and managing DDIs.
- Targeting these transporters offers potential strategies for optimizing drug therapy and minimizing adverse events.

01:25Pharmacokinetics: Drug–Drug Interactions
Drug interactions occur when the pharmacological effect of one drug is altered by another substance, either enhancing or diminishing its activity. The drug whose activity is altered is known as the object drug, and the substance causing the alteration is called the agent drug or the precipitant. The net effects of these interactions are mostly undesirable, leading to decreased effectiveness or increased adverse effects. In rare cases, interactions can be beneficial, such as the enhanced...
01:30Drug toxicity: Drug–Drug Interaction
Drug–drug interactions can precipitate toxicity through multiple mechanisms. Absorption interactions alter how drugs enter the body, exemplified when ranitidine increases the absorption of basic drugs, while cholestyramine decreases the levels of propranolol. Protein binding interactions occur when drugs share the same binding sites on plasma proteins. Drugs like aspirin and warfarin, when bound in excess, can lead to increased free drug concentrations, enhancing the potential for...
01:06Carrier-Mediated Transport
Carrier-mediated transport is a pivotal process in drug absorption, particularly for lipid-insoluble drugs, and encompasses facilitated diffusion and active transport. Facilitated diffusion allows drugs to move along their concentration gradient without energy expenditure, while active transport utilizes ATP to drive drug movement against this gradient.
Active transport involves two types of membrane-spanning transporters: uptake and efflux. Uptake transporters are expressed in the small...

01:14Hepatic Drug Clearance: Role of Transporters
In the liver and bile canaliculi, influx and efflux transporters modification can influence intrinsic clearance. Transporters play a significant role in moving drugs within liver cells. Elaborate models, such as the Biopharmaceutical Classification System (BCS), are essential to relate transporters to drug disposition. This system categorizes drugs into four classes based on solubility and permeability, providing insights into elimination routes and the effects of transporters following oral...
01:27Nonlinear Pharmacokinetics: Role of Transporters
A drug's nonlinear kinetics can be influenced by a diverse range of transporter proteins that serve as crucial players in drug distribution. These transporters, found within cells, can enhance or reduce local drug concentrations by facilitating the influx or efflux of drugs. For instance, the expression of xenobiotic transporters can be influenced by factors such as age and gender, potentially impacting the linearity of drug response.

01:16Pharmacogenetics of Drug Transporters: P-Glycoprotein and Solute Carrier Transporters
The pharmacogenetics of drug transporters is increasingly recognized as a critical factor influencing interindividual variability in drug absorption, distribution, and elimination. These membrane-bound proteins regulate drugs' movement across cellular barriers by actively pumping them out (efflux) or facilitating their uptake (influx). Among the major transporter families, ATP-binding cassette (ABC) and solute carrier (SLC) transporters play particularly prominent roles. Genetic polymorphisms...
