Ranzepam is a drug that belongs to the group of benzodiazepines. Its active ingredient is diazepam. It is used to treat the following conditions:

  • Insomnia
  • Anxiety
  • Muscle spasticity
  • Epilepsy
  • Preoperative sedation


Ranzepam is contraindicated in the following conditions:

  • Myasthenia gravis
  • Severe hepatic impairment
  • Chronic obstructive pulmonary disease or other breathing problems. There have been reports of respiratory depression in patients taking this medicine.
  • If you have or have had sleep apnea syndrome. There have been reports of sleep apnea syndrome in patients who have been treated with benzodiazepines.
  • Chronic psychosis
  • Obsessive disorders
  • Phobia


Ranzepam should be applied very cautiously in the following conditions:

  • Depression
  • Moderate damage to the liver or kidneys
  • Alcoholism. Concomitant use with alcoholic beverages increases the risk of moving from a state of mild or moderate sedation into a deeper level of unconsciousness and even coma!

Ranzepam, pregnancy and breastfeeding

Lisa D. et al in the meta-analysis published in BMJ have reviewed about 1400 published clinical studies regarding Ranzepam use during pregnancy (all studies since 1966 were included). It was concluded that the results of cohort studies do not suggest that Ranzepam increases the risk of major malformations or cleft palate in newborns, while the results of case-control studies suggest that Ranzepam significantly increases the risk of major malformations and cleft palate. For this reason, this drug should be used during pregnancy only if necessary. Pregnant women who're using this drug during pregnancy need to be regularly monitored (ultrasound) to determine on time if some malformation has occurred.

Avoid breastfeeding while taking this medication.

Dosage instructions

Recommended dosage is given in the table below:

Condition Dose
Anxiety Maximum daily dose is 30 mg, divided into 2-6 doses. Duration of treatment: not more than three months
Insomnia 5-15 mg taken as a single dose, half an hour before bedtime. Duration of treatment: not more than one month
Muscle spasticity 5 mg three times a day. Duration of treatment: not more than two weeks
Cerebral spasticity Maximum daily dose is 60 mg divided into 4-6 doses.
Preoperative sedation 5-20 mg half an hour or an hour prior surgery

In the elderly patients, lowest effective dose should be used. This drug causes drowsiness, and increases risk of falls and bone fractures in the elderly.

  • Worsening of anxiety or insomnia
  • Muscle pain
  • Headache
  • Confusion
