Study summary

The purpose of this study is to determine which of three delivery systems of vaginal diazepam have the best systemic absorption, measured by serum diazepam levels. The three delivery systems are: moistened tablet, suppository or cream. Additionally the study will compare the side effects and absorption of vaginal diazepam with oral diazepam. Vaginal diazepam is used off-label vaginally to relax pelvic floor muscles and reduce pelvic pain caused from pelvic floor dysfunction.

  • Pregnancy
  • Concomitant use of any narcotic drug, ethanol, or any illicit drug use during the study period that could be deemed unsafe in combination with benzodiazepine medication use as judged by the investigators.
  • Any evidence of vaginitis on wet mount slide
  • Subject with any other vaginal epithelial disorder that could affect absorption of medication as deemed by the investigators.
  • Any indication/condition/medication that the investigators identify as in conjunction with diazepam.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
