Novel Approaches for Minimizing Drug-Induced QT Interval Lengthening

Long QT SyndromeAbnormalities1 more

This research will determine if: 1) Oral progesterone attenuates drug-induced QT interval, J-Tpeak and Tpeak-Tend lengthening in postmenopausal women 50 years of age or older, and 2) Transdermal testosterone attenuates drug-induced QT interval, J-Tpeak and Tpeak-Tend lengthening in men 65 years of age or older. This investigation will consist of two concurrent prospective, randomized, double-blind, placebo-controlled crossover-design studies in a) Postmenopausal women, and b) Men 65 years of age or older. Study 1: Each postmenopausal woman will take progesterone or placebo capsules for 1 week. After a 14-day "washout" (no progesterone or placebo) each subject will then take the alternative therapy (progesterone or placebo) for 1 week. After 7 days of each treatment, subjects will present to the clinical research center to receive a small dose of the QT interval-lengthening drug ibutilide, and the effect on the QT, J-Tpeak and Tpeak-Tend intervals during the progesterone and placebo phases will be compared. Study 2: Each man 65 years of age or older will apply transdermal testosterone or transdermal placebo gel for 3 days. After a 7-day "washout" (no testosterone or placebo) each subject will then apply the alternative therapy (testosterone or placebo gel) for 1 week. After 3 days of each treatment, subjects will present to the clinical research center to receive a small dose of the QT interval-lengthening drug ibutilide, and the effect on the QT, J-Tpeak and Tpeak-Tend intervals during the testosterone and placebo phases will be compared.

Reducing the Risk of Drug-Induced QT Interval Lengthening in Women

Long QT SyndromeAbnormalities1 more

This research will determine if oral progesterone attenuates drug-induced QT interval lengthening in a) Postmenopausal women 50 years of age or older, and b) Premenopausal women studied during the ovulation phase of the menstrual cycle. This investigation will consist of two concurrent prospective, randomized, double-blind, placebo-controlled crossover-design studies in a) Postmenopausal women, and b) Premenopausal women. Each subject will take progesterone or placebo capsules for 1 week. After a two-week "washout" (no progesterone or placebo) each subject will then take the alternative therapy (progesterone or placebo) for 1 week. After 7 days of each treatment, subjects will present to the clinical research center to receive a small dose of the QT interval-lengthening drug ibutilide, and the effect on the QT, J-Tpeak and Tpeak-Tend intervals during the progesterone and placebo phases will be compared

Electronic Notification of Teratogenic Risks

TeratogensAbnormalities2 more

This study will use a factorial design randomized controlled trial to (1)compare multi-faceted decision support (intervention) to streamlined clinical alerts (control) and (2) evaluate whether collecting information about women's risk of pregnancy using a networked tablet computer (intervention) is superior to the way clinicians usually collect this information (control). Over the course of 1 year, we will abstract data from the electronic medical record when study clinicians prescribe teratogenic medications, conduct phone interviews with women prescribed medications by participating clinicians, and survey participating clinicians about their satisfaction with the decision support they receive. We will use this data to confirm our hypotheses that clinicians in the intervention groups will (1) prescribe fewer teratogenic medications, (2) be more likely to prescribe contraception when a teratogenic medication is prescribed, (3) have more patients report satisfaction with the counseling they received, and (4) report more satisfaction with the decision support they received.
