Taro-Terconazole

Taro-Terconazole Uses, Dosage, Side Effects, Food Interaction and all others data.

Taro-Terconazole disrupts ergosterol synthesis by binding to fungal cytochrome P450. It is active in vitro against Candida spp. and other fungi. It has some antibacterial activity in vitro but not against usual vag flora e.g, lactobacilli.

Taro-Terconazole is a triazole antifungal agent available for intravaginal use. It is structurally related to imidazole-derivative antifungal agents, although terconazole and other triazoles have 3 nitrogens in the azole ring. By inhibiting the 14-alpha-demethylase (lanosterol 14-alpha-demethylase), Taro-Terconazole inhibits ergosterol synthesis. Depletion of ergosterol in fungal membrane disrupts the structure and many functions of fungal membrane leading to inhibition of fungal growth.

Uses

Taro-Terconazole Vaginal Cream and Vaginal Suppositories are used for the local treatment of vulvovaginal candidiasis (moniliasis). As these products are effective only for vulvovaginitis caused by the genus Candida, the diagnosis should be confirmed by KOH smears and/or cultures.

Taro-Terconazole is also used to associated treatment for these conditions: Vulvovaginal Candidiasis

How Taro-Terconazole works

Taro-Terconazole may exert its antifungal activity by disrupting normal fungal cell membrane permeability. Taro-Terconazole and other triazole antifungal agents inhibit cytochrome P450 14-alpha-demethylase in susceptible fungi, which leads to the accumulation of lanosterol and other methylated sterols and a decrease in ergosterol concentration. Depletion of ergosterol in the membrane disrupts the structure and function of the fungal cell leading to a decrease or inhibition of fungal growth.

Dosage

Taro-Terconazole dosage

Taro-Terconazole Vaginal Cream 0.4%: One full applicator (5 g) of 7 Vaginal Cream (20 mg terconazole) should be administered intravaginally once daily at bedtime for seven consecutive days.

Taro-Terconazole Vaginal Cream 0.8%: One full applicator (5 g) of Vaginal Cream (40 mg terconazole) should be administered intravaginally once daily at bedtime for three consecutive days.

Taro-Terconazole Vaginal Suppositories 80 mg: One Vaginal Suppository (80 mg terconazole) should be administered intravaginally once daily at bedtime for three consecutive days.

May decrease absorption of ciprofloxacin, ciclosporin, mycophenolate, tacrolimus and levothyroxine. Sevelamer should be given 3 hr before or 1 hr after taking other drugs to minimise potential pharmacokinetic interaction.Before prescribing another course of therapy, the diagnosis should be reconfirmed by smears and/or cultures and other pathogens commonly associated with vulvovaginitis ruled out. The therapeutic effect of these products is not affected by menstruation.

Store at Controlled Room Temperature 15–30°C

Side Effects

Vulvovaginal burning, vulvar itching, dysmenorrhoea, genital, body and abdominal pain. Flu-like syndrome with headache, fever, chills and hypotension with doses >80 mg.

Toxicity

The oral LD50 values were found to be 1741 and 849 mg/kg for the male and female in rat.

Precaution

Discontinue use and do not retreat with terconazole if sensitization, irritation, fever, chills or flu-like symptoms are reported during use. The base contained in the suppository formulation may interact with certain rubber or latex products, such as those used in vaginal contraceptive diaphragms; therefore concurrent use is not recommended.

Interaction

May decrease absorption of ciprofloxacin, ciclosporin, mycophenolate, tacrolimus and levothyroxine. Sevelamer should be given 3 hr before or 1 hr after taking other drugs to minimise potential pharmacokinetic interaction.

Food Interaction

No interactions found.

Elimination Route

Following intravaginal administration of terconazole in humans, absorption ranged from 5-8% in three hysterectomized subjects and 12-16% in two non-hysterectomized subjects with tubal ligations

Half Life

6.9 hours (range 4.0-11.3)

Elimination Route

Following oral (30 mg) administration of 14C-labelled terconazole, excretion of radioactivity was both by renal (32-56%) and fecal (47-52%) routes.

Pregnancy & Breastfeeding use

Pregnancy Category C. There was no evidence of teratogenicity when terconazole was administered orally up to 40 mg/kg/day (25x the recommended intravaginal human dose of the suppository formulation, 50x the recommended intravaginal human dose of the 0.8% vaginal cream formulation, and 100x the intravaginal human dose of the 0.4% vaginal cream formulation) in rats, or 20 mg/kg/day in rabbits, or subcutaneously up to 20 mg/kg/day in rats.

Nursing Mothers: It is not known whether this drug is excreted in human milk. Animal studies have shown that rat offspring exposed via the milk of treated (40 mg/kg/orally) dams showed decreased survival during the first few post-partum days, but overall pup weight and weight gain were comparable to or greater than controls throughout lactation. Because many drugs are excreted in human milk, and because of the potential for adverse reaction in nursing infants from terconazole, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Contraindication

Patients known to be hypersensitive to terconazole or to any of the components of the cream or suppositories.

Special Warning

Pediatric Use: Safety and efficacy in children have not been established.

Geriatric Use: Clinical studies of terconazole did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.

Acute Overdose

Overdose of terconazole in humans has not been reported to date. In the rat, the oral LD 50 values were found to be 1741 and 849 mg/kg for the male and female, respectively. The oral LD 50 values for the male and female dog were @ 1280 and ≥ 640 mg/kg, respectively.
