Vaginal Rings, Drug Delivery
Definition : Vaginal rings are flexible copolymer rings that release or emit drugs during use and are intended to be used as intra-vaginal drug-delivery devices. Drug delivery vaginal rings that emit hormones to prevent pregnancy in women of child-bearing age, or to treat urogenital symptoms, are available. The muscles of the vagina keep the drug delivery vaginal ring securely in place until removed by the user. Drug delivery vaginal rings are used for continuous drug delivery for as long as the treatment is prescribed, after which they must be removed. If treatment should continue (as in birth control rings), the patient removes the expired ring and replaces it on a schedule.
