Rozerem vs Ambien

Rozerem vs Ambien – detailed comparison:


It is the brand name of a drug called ramelteon, a sedative that works by affecting certain substances in the human body which help regulate the circadian rhythm (also known as the sleep-wake cycle).

It is the first prescription sleep medication that has shown no evidence of dependence, abuse, or withdrawal. Its approval was supported by a number of clinical trials, investigating both the drug’s abuse-potential and tolerability profiles and the efficacy of the sedative.

This medication is produced by Takeda Pharmaceutical, the largest pharmaceutical company in Asia and Japan.


It is approved for use in adults having trouble falling asleep due to insomnia, a sleep disorder that is described by difficulty falling and/or staying asleep.

According to the data, people with this condition have one or more of the following symptoms:

  • waking up too early in the morning;
  • difficulty falling asleep;
  • fatigue or low energy;
  • problems at work or school;
  • waking up during the night and having problems returning to sleep;
  • difficulty in personal relationships;
  • behavior problems, like – feeling aggression or being impulsive;
  • mood disturbance, like – irritability;
  • cognitive impairment, like – difficulty concentrating;
  • unrefreshing sleep.

Insomnia can be caused by:

  • unhealthy sleep habits;
  • medical and psychiatric conditions;
  • certain biological factors;
  • specific substance abuse.


The usual recommended dose for an adult is 8 mg orally, no earlier than 30 minutes before bedtime. This is also the maximum recommended dose.

Because it will make it harder for the body to absorb the medication, avoid taking it together with or just after eating a high-fat meal.

Moreover, it should not be taken by those suffering from severe liver problems or a chronic obstructive pulmonary disease or in combination with the antidepressant called Luvox.

Note – your sleep problems should improve within 7 to 10 days after you start the treatment. Call your healthcare provider if your condition does not improve during this time.

It is the brand name of a medication called zolpidem which belongs to a class of medications called sedative-hypnotics. It acts on the brain to produce a calming effect by increasing the activity of gamma-aminobutyric acid (GABA) – a chemical in the body that causes sleepiness. Increasing gamma-aminobutyric acid activity helps people fall asleep faster.


It is commonly used to treat insomnia, a condition that causes trouble falling asleep or staying asleep. Doctors typically prescribe this sedative-hypnotic for 7 to 14 days or less because its main ingredient can have some substantial negative side effects.

Bottom Line – Rozerem vs Ambien

Rozerem (active ingredient – ramelteon) is a sedative that works by affecting certain substances in the body which help regulate the sleep-wake cycle. It is unique among approved sleep-promoting drugs due to the absence of sedating effects and abuse liability as well as the mechanism of action targeting the activity in the suprachiasmatic nucleus.

Ambien (active ingredient – zolpidem) is a drug that is used to treat insomnia, a sleep disorder that makes it difficult for a person to stay asleep or go to sleep. It works by slowing the activity in the brain, allowing you to reach a state of sleep.

While both medications can be effective, it is important to speak with a doctor to determine which one is right for you.
