Idiopathic Pulmonary Fibrosis

Idiopathic Pulmonary Fibrosis

Idiopathic pulmonary fibrosis (IPF) is a chronic and progressive fibrotic interstitial lung disease that occurs mostly in older adults, is limited to the lungs and often displays a characteristic imaging and histological appearance. Find out how to diagnose IPF and the latest interventions available for patients living with this burden.

Advisory information

contraindications
CONTRAINDICATIONS Patients known to be hypersensitive to terconazole or to any of the components of the cream.
Special warnings and precautions
PRECAUTIONS General For vulvovaginal use only. Terconazole is not for ophthalmic or oral use. Discontinue use and do not retreat with terconazole if sensitization, irritation, fever, chills or flu-like symptoms are reported during use. Laboratory Tests If there is lack of response to terconazole, appropriate microbiologic studies (standard KOH smear and/or cultures) should be repeated to confirm the diagnosis and rule out other pathogens. Drug Interactions The therapeutic effect of terconazole is not affected by oral contraceptive usage. The levels of estradiol and progesterone did not differ significantly when 0.8% terconazole vaginal cream was administered to healthy female volunteers established on a low dose oral contraceptive. Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Studies to determine the carcinogenic potential of terconazole have not been performed. Mutagenicity Terconazole was not mutagenic when tested in vitro for induction of microbial point mutations (Ames test), or for inducing cellular transformation, or in vivo for chromosome breaks (micronucleus test) or dominant lethal mutations in mouse germ cells. Impairment of Fertility No impairment of fertility occurred when female rats were administered terconazole orally up to 40 mg/kg/day for a three month period. Pregnancy Teratogenic Effects There was no evidence of teratogenicity when terconazole was administered orally up to 40 mg/kg/day (50× the recommended intravaginal human dose of the 0.8% vaginal cream formulation, and 100× 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. Dosages at or below 10 mg/kg/day produced no embryotoxicity; however, there was a delay in fetal ossification at 10 mg/kg/day in rats. There was some evidence of embryotoxicity in rabbits and rats at 20–40 mg/kg. In rats, this was reflected as a decrease in litter size and number of viable young and reduced fetal weight. There was also delay in ossification and an increased incidence of skeletal variants. The no-effect dose of 10 mg/kg/day resulted in a mean peak plasma level of terconazole in pregnant rats of 0.176 mcg/mL which exceeds by 44 times the mean peak plasma level (0.004 mcg/mL) seen in normal subjects after intravaginal administration of terconazole 0.4% vaginal cream, and by 30 times the mean peak plasma level (0.006 mcg/mL) seen in normal subjects after intravaginal administration of terconazole 0.8% vaginal cream. This safety assessment does not account for possible exposure of the fetus through direct transfer to terconazole from the irritated vagina by diffusion across amniotic membranes. Since terconazole is absorbed from the human vagina, it should not be used in the first trimester of pregnancy unless the physician considers it essential to the welfare of the patient. Terconazole may be used during the second and third trimester if the potential benefit outweighs the possible risks to the fetus. 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. 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.
Adverse reactions
ADVERSE REACTIONS Adverse Reactions from Clinical Trials Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Terconazole Vaginal Cream 0.4% During controlled clinical studies conducted in the United States, 521 patients with vulvovaginal candidiasis were treated with terconazole 0.4% vaginal cream. Based on comparative analyses with placebo, the adverse experiences considered most likely related to terconazole 0.4% vaginal cream were headache (26% vs. 17% with placebo) and body pain (2.1% vs. 0% with placebo). Fever (1.7% vs. 0.5% with placebo) and chills (0.4% vs. 0.0% with placebo), vulvovaginal burning, itching and irritation have also been reported. The adverse drug experience on terconazole most frequently causing discontinuation was vulvovaginal itching. Terconazole Vaginal Cream 0.8% During controlled clinical studies conducted in the United States, patients with vulvovaginal candidiasis were treated with terconazole 0.8% vaginal cream for three days. Based on comparative analyses with placebo and a standard agent, the adverse experiences considered most likely related to terconazole 0.8% vaginal cream were headache (21% vs. 16% with placebo) and dysmenorrhea (6% vs. 2% with placebo). Other adverse experiences reported with terconazole 0.8% vaginal cream were abdominal pain (3.4% vs. 1% with placebo) and fever (1% vs. 0.3% with placebo). The adverse drug experience most frequently causing discontinuation of therapy was vulvovaginal itching, 0.7% with the terconazole 0.8% vaginal cream group and 0.3% with the placebo group. Post-marketing Experience The following adverse drug reactions have been first identified during post-marketing experience with terconazole. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. General: Asthenia, Influenza-Like Illness consisting of multiple listed reactions including fever and chills, nausea, vomiting, myalgia, arthralgia, malaise Immune: Hypersensitivity, Anaphylaxis, Face Edema Nervous: Dizziness Respiratory: Bronchospasm Skin: Rash, Toxic Epidermal Necrolysis, Urticaria

Usage information

Dosing and administration
DOSAGE AND ADMINISTRATION Terconazole Vaginal Cream 0.4% One full applicator (5 g) of Terconazole Vaginal Cream (20 mg terconazole) should be administered intravaginally once daily at bedtime for seven consecutive days. Terconazole Vaginal Cream 0.8% One full applicator (5 g) of Terconazole Vaginal Cream (40 mg terconazole) should be administered intravaginally once daily at bedtime for three consecutive days. 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.
Pregnancy and lactation
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.

Interactions

Drug Interactions The therapeutic effect of terconazole is not affected by oral contraceptive usage. The levels of estradiol and progesterone did not differ significantly when 0.8% terconazole vaginal cream was administered to healthy female volunteers established on a low dose oral contraceptive.
