Context and Aims: Pregnant women undergo physiological changes which influence the efficacy as well as safety of medications used. Very few drugs are tested and approved for medical conditions during pregnancy, and less pharmacokinetic data are available to form clinical treatment guidelines. There was no data available regarding the type of research studies conducted in pregnancy in India. Hence, we conducted this study to analyze the type of research studies in pregnancy registered in the Clinical Trials Registry of India (CTRI). Subjects and Methods: Following exemption from review by the Institutional Ethics Committee, all studies in pregnant women registered in CTRI from its inception in July 2007 to June 2018 were reviewed. Data were captured with respect to geographical distribution, trimester of pregnancy, study designs used, therapy area, and funding. Statistical Analysis Used: The variables were analyzed using descriptive statistics using SPSS version 16.0. Results: Out of a total of 14,911 studies in CTRI, a total of 285 (1.91%) studies involved pregnant women. Of these studies, 199 (69.8%) were interventional, whereas 86 (30.1%) were observational. Of all the interventional studies, 119 (60%) tested drugs, 47 (24%) tested a nondrug intervention, and the rest were nutraceuticals, Ayurveda, Yoga and Naturopathy, Unani, Siddha, and Homeopathy, and vaccines. Postgraduate theses constituted 140 (49.1%) studies, 79 (27.7%) were academic projects, 27 (9.4%) were government-funded studies, and only 16 (5.6%) were pharmaceutical-sponsored studies. The most commonly studied therapy area was anesthesia, followed by hypertension and induction of labor. Conclusions: This study depicts underrepresentation of pregnant women in clinical studies and more evidence needs to be generated with respect to drug safety and pharmacokinetics.
