Alpazolam, better known as Xanax is a drug categorized as a benzodiazepine. Due to the high abuse rates in the USA, tests have been created to detect the drug in body fluids and tissue. On average, for a healthy person, Xanax elimination half-life is 9 to 16 hours.

Elderly people are not able to excrete the drug as fast because of the altered blood flow and the deterioration of internal functions as a result of aging. Therefore the older you are the longer it takes to clear Xanax from the body. For individuals with impaired kidney or liver functions they retain the drug for a longer period. Body size also influences the rate at which the body excretes Xanax. The larger the individual the smaller the amount of drug in proportion to their body size hence it is easier to clear.

Ingesting Other Drugs Impacts How Long Xanax Lasts & Can Be Detected in the Urine, Blood & System

Taking other drugs whether prescription or illicit can alter the ability of the body to metabolize Xanax. These drugs can either be inhibitors or inducers of the enzymatic function of the CYP3A4 which is in the liver. Inhibitor drugs inhibit this enzymatic function and prolong the excretion of the drug. Such drugs include Cimetidine and Ketoconazole. Inducers such as Nafcilin on the other hand enhance the CYP3A4 ability to break down the Xanax hence increases the average clearance rates from 0.9ml/min/kg up to 2.13ml/min/kg.

Frequent users or long-term users build up tolerance rapidly and also accumulate the drug to a greater extent in their bodies hence taking them longer to metabolize and excrete the drug as compared to infrequent users.

According to research 16 million Americans aged 12 and above use the drug for recreational purposes at least once. These statistics indicate that it is the most addictive and among the most abused legal drugs.
