drug AmbienZolpidem is an active substance of Ambien pill which dissolves in the body quickly and it helps you to stay asleep for more than 8 hours. The half-life of Ambien is 2 to 3 hours. Numerous studies stated that Ambien drug’s half-life is 2.3 hours. It implies 50% of the medication will be discharged from the body within few hours and expected duration time of complete exertion of the drug from the system is 11 to 16.5 hours. On a normal, individuals will have a tendency to remove Ambien medication in a period of 14 hours back of the last swallowed dose.

A few researchers report that the metabolites of Zolpidem like Zolpidem 6-carboxylic corrosive (ZCA) and  Zolpidem phenyl-4-carboxylic corrosive (ZPCA) remain its effectiveness for longer duration in the body. It has been noticed that metabolites will take 3 days to get discharged from the body.

Factors that impact how long Ambien stays in your body

As of now said, the half-life of Ambien is only a few hours. The complete medication will take around 14 hours to get discharged from the body. Although, it is only a normal figure and the time span is profoundly factored among people, depends upon numerous variables. Such factors include individual characteristics, dosages, co-carried out medications, regularity and course duration of utilization.

Individual Characteristics:

These attributes include genders, age, hydration, body mass, kidney and liver functions.

  • Genetics -The genetics plays a major role in deciding the duration of a drug removal from the body. People bearing CYP3A4’18 allele have more articulation of CYP3A4 isoenzymes. These are engaged with the fundamental digestion of Zolpidem. Improved articulation prompts a quicker digestion. Whereas people communicating CYP2C19’2 have slower rates of metabolism.
  • Body Mass – People those who have larger body mass are accomplished for metabolizing and discharging the medications at faster rates. Numerous individual having a tall height will discharge the medication sooner than his partner having a little tallness and low weight.
  • Age – The drug leaving procedure is slower in an elder person because of lower levels of free testosterone, decreased hepatic stream, and attendant utilization of drugs for other health conditions. Younger individuals have higher utilization and discharge rate of Ambien than elder individuals.
  • A Urinary potential of hydrogen – The Ambien reabsorption has been prevented by the acidic pH and it keeps through the kidney tubules so the entire of the medication gets discharged. People flaunting basic pH have a slower rate of medication disposal through urine. The pH is subject to the kind of food eaten by an individual. Limes, fig, carrots, and dates enable the pH to be more soluble.
  • Food intake – The ingestion rate of medication is slower on a full stomach than an empty stomach. In addition, a few foods can further influence the retention time of Zolpidem.
  • Liver Functions – Hepatic proteins are associated with the procedure of digestion. Any disability of liver procedures can back off the digestion. It has been discovered that the half-life of Ambien was stretched out to 10 hours in the patients with cirrhotic.
  • SexIt is also one of the factors that influence the medication long-lasting in the body. Men have higher utilizing rates than women. It depends on higher testosterone levels in males.
  • BMR– A person who has a high Basal Metabolic Rate would have the tendency to burn more vitality while resting so they are equipped for utilizing Ambien faster than individuals with a low BMR.

Co-Administration of Medications

Numerous supplements and medications can impact the liver enzymes. Few of the medicines can increase the metabolism rate while others have the tendency to decrease it down. Medications like Ritonavir, Nelfinavir, Indinavir, Ketoconazole, and clarithromycin have inhibitory impacts on liver enzymes.  Oxcarbazepine, Carbamazepine, Rifampicin, and  Phenobarbitol have the capability to increase the liver enzymes functionalities.


More time is taken for the drug discharging process while taken at higher dosages. Usually larger doses utilize more time to get metabolized and get discharged. A large quantity of medication is processed through the system and enable the person exposed to reabsorption process via kidney tubules.

Regularity and Course Duration

The administration of medication regularly can result in larger accumulation and lessen the discharge of Zolpidem. Course duration of utilization further gives towards the medicine elimination time from the system. The longer time duration prompts more prolonged drug removal.
