Intravaginal administration
Intravaginal administration is a route of administration where the substance is applied inside the vagina. Pharmacologically, it has the potential advantage to result in effects primarily in the vagina or nearby structures with limited systemic adverse effects compared to other routes of administration.
Formulation methods include vaginal tablets, vaginal cream, vaginal gel, vaginal suppository and vaginal ring.
Medicines primarily delivered by intravaginal administration include vaginally administered estrogens and progestogens, and antibacterials and antifungals to treat bacterial vaginosis and yeast infections respectively.
Medicines may also be administered intravaginally as an alternative to oral route in the case of nausea or other digestive problems.
It is a potential means of artificial insemination, sometimes used at home without the presence of a professional.
It is used as a method of on-demand contraception.
