Abstract
Introduction Nationwide prevalence of potentially harmful drug prescribing during pregnancy is unknown in France, and several risk classification systems (RCS) exist to guide prescribers. Objective The aim of this study was to estimate the nationwide prevalence of potentially harmful drug prescribing during pregnancy in France and to describe maternal characteristics associated with this prescription. Methods This drug utilisation study, conducted on the French health databases (67 million beneficiaries), included all pregnancies beginning in 2016–2017, regardless of pregnancy outcome. Potentially harmful drug prescribing was defined as at least one reimbursement during pregnancy of Swedish RCS category D drugs, Australian RCS category D/X drugs, or contraindicated drugs in France for drugs not listed in these two RCSs. Maternal characteristics associated with potentially harmful drug prescribing were described using a univariate logistic regression analysis. Results Among the 1,844,447 pregnant women identified, the prevalence of potentially harmful drug prescribing was higher according to the Australian RCS (3.9%) than according to the Swedish RCS (2.2%), with good agreement between the two RCSs (Kappa = 0.81 [0.74–0.87]). This prevalence increased to 9.2% and 6.9%, respectively, when considering contraindications in France. Prescribing of teratogenic drugs, including retinoids and valproate, was highest during the first trimester, whereas prescribing of foetotoxic drugs decreased after the first trimester but remained high for nonsteroidal anti-inflammatory drugs (N = 10,021). In women with no chronic diseases, polymedication (five or more drugs) was the strongest maternal characteristic associated with potentially harmful drug prescribing in both RCSs. Conclusions Potentially harmful drug prescribing during pregnancy is not uncommon in France. This study supports the comparative analysis of RCS to assess potentially harmful drug prescribing in claims databases.

Risk of Pregnancy Termination and Congenital Anomalies After Domperidone Exposure: A Study in the EFEMERIS Database. Drug Saf 2021; 44:787-796. [PMID: 33970448 DOI: 10.1007/s40264-021-01077-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/23/2021] [Indexed: 10/21/2022]
Abstract
INTRODUCTION Domperidone is widely used during pregnancy, although the risks associated with pregnant women have not been adequately evaluated. OBJECTIVE The objective of this study was to compare the rate of pregnancy outcomes and congenital anomalies between pregnant women exposed and unexposed to domperidone during pregnancy. METHODS We conducted a retrospective cohort study comparing pregnant women exposed and unexposed to domperidone during pregnancy. We used the EFEMERIS database containing the prescriptions and dispensing of drugs to pregnant women in Haute-Garonne, who had a pregnancy outcome between July 2004 and December 2017. We compared pregnant women who were exposed to domperidone at least once during pregnancy to unexposed pregnant women. Logistic regression and Cox proportional risk models were applied. RESULTS Overall, 13,964 pregnancies (10.3% of pregnancies) were given domperidone. A reduction in the number of pregnant women exposed to domperidone (2004: 17.1% to 2017: 1.2%) was noted. More than 75% of pregnancies were exposed to domperidone in the first trimester of pregnancy. The rate of natural pregnancy termination in pregnant women exposed to domperidone was lower than that in unexposed pregnant women (adjusted hazard ratio = 0.78 [0.71-0.87]). The malformation rate in fetuses/newborns exposed in utero (first trimester) to domperidone is comparable to that of unexposed fetuses/newborns (adjusted odd ratio = 0.89 [0.77-1.03]). CONCLUSIONS This is the first comparative study to enrol a large number of pregnant women exposed to domperidone. Data regarding the malformation rate following exposure to domperidone during the first trimester of pregnancy are reassuring. Women exposed to domperidone during pregnancy have a decreased risk for natural pregnancy termination, probably owing to an indication bias.

Evaluation of the pregnant women's approaches regarding drug utilization. North Clin Istanb 2021; 8:49-56. [PMID: 33623873 PMCID: PMC7881424 DOI: 10.14744/nci.2020.27003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2020] [Accepted: 08/27/2020] [Indexed: 11/25/2022] Open
Abstract
OBJECTIVE: Drug utilization habits of the pregnant are a critical aspect of rational use of the medicine (RUM). This study aimed to analyze the RUM related attitudes and the behaviors of women during their pregnancies. METHODS: The data were collected between May 2016–October 2016 by conducting surveys to 71 pregnant women admitted to the private and governmental hospitals in five districts of Northern Cyprus. The sociodemographic characteristics of the pregnant as well as their attitudes and behaviors concerning drug use were evaluated. RESULTS: The mean age and the gestational week of the patients was 29.7±4.3 years and 25.7±11.2 weeks, respectively. Planned pregnancies constituted 71.8% of all. The percentage of patients with an unplanned pregnancies who were using drugs at the time of the survey (25.0%) was lower than that in those with planned pregnancies (49.0%, p<0.05). Almost two-thirds (66.2%) of the women were exposed to a drug during pregnancy, mostly for “vitamin/mineral prophylaxis” (38.3%) and agents controlling nausea/vomiting (19.1%). Two out of eleven women (18.2%) were using folic acid when they learned about their pregnancy. One of the drugs used for the chronic disorder in the third trimester was acetylsalicylic acid (11.1%), a category D drug in this setting. Most of the patients stated that they frequently read the instructions (60.9%), “often” paying attention to side effects (56.5%). Considering some of the habits related to drug use, 8.7% and 10.9% of pregnant women declared that they sometimes “did not follow the instructions” and “dosage/duration of the drug usage”, respectively. Seven patients (15.2%) declared that they did not consider side effects on the medication guide while more than half (56.5%) did it “often”. Near one in five (19.6%) of the pregnant women stated that they hesitated about the drug usage due to teratogenicity risks. CONCLUSION: Our study highlights the drug utilization attitudes and behaviors of pregnant women during pregnancy in Northern Cyprus, indicating several shortcomings, including insufficient prenatal folic acid use, occasional use of risky drugs, and unsatisfactory medication guide handling. Available findings underline the necessity of education not only for patients but also for healthcare providers to disseminate RUM in pregnancy.

Abstract
Purpose This study aims to illustrate the prevalence and patterns of medication use among pregnant women in mainland China. Patients and methods Hospital and drugstore service data for a nationally representative sample of basic medical insurance (BMI) beneficiaries in 2015 were obtained from the China Health Insurance Association (CHIRA) database. A total of 7946 women who had singleton deliveries in 2015, aged between 12 and 54, and whose records in the CHIRA database covered at least one trimester were included in this study. We conducted descriptive analyses of sample characteristics, medication use prevalence, and number and types of medications used. Results We found that 11.7% of women used at least one medication during the course of pregnancy (median number of medications used = 6.7). Medication use was more common among those who were older, residing in Eastern China, or employed. Most commonly used medication groups by the Anatomical Therapeutic Chemical Classification System were B (Blood and blood forming organs, 49.3%), A (Alimentary tract and metabolism, 48.1%), G (Genito urinary system and sex hormones, 38.1%) and J (Antiinfectives for systemic use, 31.6%). Intravenous solutions, vitamins and minerals, progestogens, and beta-lactam antibacterials were the most frequently used medications from each of these four ATC groups, respectively. Moreover, 7.1% used at least one medication contraindicated in pregnancy. Conclusion This study showed that around one in 10 women used medication during pregnancy in mainland China and found possible cases of inappropriate or unsafe medication use.

Efficacy of phloroglucinol for the treatment of pain of gynaecologic or obstetrical origin: a systematic review of literature of randomised controlled trials. Eur J Clin Pharmacol 2019; 76:1-6. [PMID: 31435708 DOI: 10.1007/s00228-019-02745-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2019] [Accepted: 08/09/2019] [Indexed: 10/26/2022]
Abstract
PURPOSE Antispasmodics like phloroglucinol are commonly used to alleviate pain. Various authorities recommend the use of this drug for conditions such as dysmenorrhoea, threatened abortion or labour pains. The goal was to carry out a systematic review analysing the existing data concerning the efficacy of phloroglucinol to treat pain in obstetrical or gynaecologic cases. The protocol was registered in Prospero (CRD 42018094065). METHODS The keywords "phloroglucinol" and "randomised controlled trials" were used to search Medline, Embase and the Cochrane Library. We selected randomised, controlled against placebo trials testing the effect of phloroglucinol on gynaecologic or obstetrical pain either as a primary or secondary endpoint. We excluded trials exploring pain caused by intestinal, renal, metabolic or other causes and trials that were not available for critical review in either English or French. A quantitative synthesis (meta-analysis) was planned if the included trials were sufficiently homogenous. If this were not the case, a descriptive synthesis would be presented. RESULTS Twelve trials identified studied the effect of phloroglucinol in gynaecologic or obstetrical conditions. Only two trials corresponded to the inclusion criteria of this review, one of which was not available for critical review. CONCLUSIONS Phloroglucinol is not well evaluated in this field. Whether for labour pains, abortion pains or benign gynaecologic pains, the results found are insufficient to promote the use of this drug in these indications.

Abstract
Purpose We described the medication use during pregnancy in the French population using the French Pregnancy Cohort (FPC). Methods The FPC was built with the sampling of all pregnant women included in the French Echantillon généraliste des bénéficiaires (EGB), which is a 1/97th representative sample of the population covered by the French health insurance. The EGB includes anonymized information on the socio-demographic and medical characteristics of beneficiaries, and the health care services they have received such as diagnoses and procedure codes as well as data on filled reimbursed medication; EGB also includes data on hospital stays in all public and private French health facilities. Each filled prescription record contains information on drug brand and generic names, date of prescription and date of dispensing, quantity dispensed, mode of administration, duration of prescription, dosage, and prescribing physician specialty. FPC includes data on all pregnancies of women in the EGB (2010–2013). Date of entry in the FPC is the first day of pregnancy regardless of pregnancy outcome (spontaneous abortions or planned abortions (with or without medical reasons), deliveries), and data on women are collected retrospectively for a period of one year before pregnancy, and prospectively during pregnancy, and up to one year after delivery. The prevalence of prescribed medications before, during and after pregnancy was compared; comparison was also done between trimesters. Pregnancy outcomes are described and include spontaneous and planned abortions, livebirths, and stillbirths. Results FPC includes data on 36,065 pregnancies. Among them, 27,253 (75.6%) resulted in a delivery including 201 stillbirths (0.7%). The total number of spontaneous abortions was 6,718 (18.6%), and planned abortions 2,094 (5.8%). The prevalence of filled medication use was 91.1%, 89.9%, and 95.6% before, during and after pregnancy, respectively. Although there was a statistically significant decrease in the proportion of use once the pregnancy was diagnosed (first trimester exposure, 76.4% vs. exposure in the year prior to pregnancy, 91.1% (p < .01)), post-pregnancy medication use was above the pre-pregnancy level (95.6%). Maternal depression was the most prevalent comorbidity during pregnancy (20%), and post-partum depression was higher in those who delivered a stillborn infant (38.8%) as well as in those with a spontaneous (19.5%) or planned abortion (22.4%) compared to those with a liveborn (12.0%). Conclusion FPC is an excellent tool for the study of the risk and benefit of drug use during the perinatal period. FPC has the advantage of including a representative sample of French pregnant women, and study medications only available in France in addition to others available worldwide.

Abstract
PURPOSE To provide an up-to-date account of drug prescription during pregnancy in France from 2011 to 2014 using the permanent sample of the French national computerized healthcare database and with a focus on recommended supplementations, fetotoxic drugs and teratogenic drugs. METHODS All pregnancies identified by the International Classification of Diseases, 10th Revision codes list in the hospitalization database, lasting more than 9 weeks of amenorrhea and whose delivery occurred between 01/01/2011 and 12/31/2014, were included. Drugs delivered between the trimester before and until the end of the pregnancy were included. Drug exposure prevalence was calculated for each year and according to pregnancy trimesters. RESULTS The study included 28,491 pregnancies with a median number of 9 [5-13] (median [IQ range]) drugs delivered. The most prescribed drug class was antianemia (in 72.5% of exposed). The prescription rate of recommended vitamins (B9 and D) increased over the study period (+10%). Influenza vaccination also increased but remained at a low rate (1%). Exposure to fetotoxic drugs decreased as pregnancy advanced. Exposure to the main teratogenic antiepileptics was stable over the study period. Low-income pregnant women had a higher average drug consumption except for recommended vitamins. CONCLUSION Pregnant French women are among the largest consumers of prescription medications worldwide. Overall, the dispensation trends observed in this study are in line with the recommendations of the French National College of Gynecologists and Obstetricians. Nevertheless, while being low, exposure to fetotoxic drugs, teratogenic drugs or those under safety alerts still occurred. Supplementations and vaccines in low-income pregnant women should also be increased.

Abstract
Purpose: To elucidate drug use before and during pregnancy in Japan. Methods: The Japan Environment and Children's Study (JECS) is an ongoing nationwide birth cohort study. We analyzed data from JECS involving cases where drugs were used for 12 months before pregnancy was diagnosed, between the time of diagnosis of pregnancy until week 12 of pregnancy, and after week 12 of pregnancy. Results: We analyzed data from 97,464 pregnant women. The percentages of pregnant women who had taken one or more drugs and supplements before diagnosis of pregnancy, between the time of diagnosis of pregnancy until week 12 of pregnancy, and after week 12 of pregnancy, were 78.4%, 57.1%, and 68.8% respectively. Excluding iron supplements, folic acid, and other vitamins and minerals, the percentages of women taking supplements were 75.3%, 36.0%, and 51.7% at each respective time point. The following drugs and supplements were frequently used for 12 months before pregnancy diagnosis: Commercially available antipyretics, analgesics, and/or medicine for treating common cold (34.7%), antipyretics, analgesics, and/or medicine for treating common colds, which were prescribed in hospitals (29.8%), antimicrobial drugs (14.0%), and anti-allergy drugs (12.5%). The following drugs and supplements were frequently used from the time of pregnancy diagnosis until week 12 of pregnancy, and after week 12 of pregnancy: folic acid (28.9% and 26.2%), antipyretics, analgesics and/or medicines for treating common cold, that were prescribed in hospitals (7.8% and 13.3%), Chinese herbal medicines (6.0% and 9.4%, and uterine relaxants (5.1% and 15.2%). Conclusions: The analysis of a nationwide cohort study showed that a high percentage of Japanese pregnant women were taking medicinal drugs. Further research is required to elucidate the relationship between drug use during pregnancy and birth defects in Japan.

Abstract
UNLABELLED Managing medical complications in pregnancy is a challenge to clinicians. OBJECTIVES This study profiled some disease and prescription patterns for pregnant women attending antenatal clinics (ANCs) in Nigeria. A risk classification of the medicines was also determined. METHODS Medical case files of 1,200 pregnant women attending antenatal clinics of 3 health facilities in Benin City, Nigeria were investigated. Disease pattern was determined from their diagnoses. The prescription pattern was assessed using WHO indicators, and the United States Food and Drug Administration classification of medicines according to risk to the foetus. RESULTS A total of 1,897 prescriptions of the 1,200 pregnant women attendees during the period under review were evaluated. Results indicated that malaria 554 (38%) was the most prevalent disease, followed by upper respiratory tract infections (URTIs, 13%) and gastrointestinal disturbances (GIT, 12%). The average number of drugs prescribed per encounter was found to be 3.0, and 2,434 (43%) of medicines were prescribed by generic name. Minerals/ Vitamins 2,396 (42%) were the most frequently prescribed medicines, and antibiotics occurred in 502 (8.8%) of the total medicines. Of all medicines prescribed, 984 (17%) were included in the foetal risk category C and 286 (5%) in category D. CONCLUSION The study concluded that malaria fever occurred most frequently followed by URTIs and GIT disturbances among the pregnant women. Minerals, vitamins and to a less extent antimalarials topped the list of the prescribed medicines. The average number of medicines per encounter was much higher than WHO standards. The occurrence of contraindicated medicines was low.

Abstract
OBJECTIVE Many women are exposed to medications during pregnancy. The Quebec Pregnancy Cohort (QPC) is a prospective population-based cohort which includes all data on pregnancies and children between January 1997 and December 2008. METHODS We linked four administrative databases in Quebec, Canada: RAMQ (medical and pharmaceutical), MED-ECHO (hospitalizations), ISQ (births/deaths), and MELS (Ministry of Education). Pregnancies included were covered by the Quebec prescription drug insurance plan (36% of women aged 15-45 years) from 12 months prior until the end of pregnancy. RESULTS We analyzed 97,680 pregnancies. Prevalence of medication use was 74% pre-pregnancy, 56% during pregnancy, and 80% post-pregnancy. Most frequently used medications during pregnancy were antibiotics (47%), antiemetic drugs (23%), and non-steroïdal anti-inflammatory drugs (NSAIDs) [17%]. Medication users were more likely to have spontaneous abortions, preterm births, children with congenital malformations and postpartum depression than non-users (p<0.01). CONCLUSION Medications are commonly used during pregnancy. The QPC is a powerful tool for perinatal pharmacoepidemiological research.

Abstract
PURPOSE We evaluated the potential and the validity of the Quebec Pregnancy Cohort (QPC) as a research tool in perinatal pharmacoepidemiology. METHODS The QPC was built by linking four administrative databases: RAMQ (medical and pharmaceutical data), Med-Echo (hospitalizations), ISQ (births/deaths), and MELS (Ministry of Education data). A self-administered questionnaire was sent to a random sample of women to collect lifestyle information. The QPC includes data on all pregnancies of women covered by the Quebec provincial prescription drug insurance between 1998 and 2008. Date of entry in the QPC is the first day of pregnancy, and women are followed during and after pregnancy; children are followed after birth up until 2009. The prevalence of prescribed medications before, during and after pregnancy was compared between time-window. Pregnancy outcomes were also estimated among pregnancies ending with a live born infant. RESULTS The QPC included 289,688 pregnancies of 186,165 women. Among them, 167,398 ended with a delivery representing 19.4% of all deliveries occurring in the Province of Quebec between 1998-2009. The total frequency of abortions was 35.9% in the QPC comparable to the 36.4% observed in the Province of Quebec. The prevalence of prescribed medication use was 74.6%, 59.0%, and 79.6% before, during and after pregnancy, respectively. Although there was a statistically significant decrease in the proportion of use once the pregnancy was diagnosed (p<.01), post-pregnancy prescribed medication use returned above the pre-pregnancy level. The prevalence of pregnancy outcomes found in the QPC were similar to those observed in the Province of Quebec. CONCLUSION The QPC is an excellent tool for the study of the risk and benefit of drug use during the perinatal period. This cohort has the advantage of including a validated date of beginning of pregnancy giving the possibility of assigning the exact gestational age at the time of maternal exposure.

Abstract
Background Antibiotic treatment during pregnancy and birth is very common. In this study, we describe the estimated prevalence of antibiotic administration during pregnancy and birth in the COPSAC2010 pregnancy cohort, and analyze dependence on social and lifestyle-related factors. Methods 706 pregnant women from the novel unselected Copenhagen Prospective Study on Asthma in Childhood (COPSAC2010) pregnancy cohort participated in this analysis. Detailed information on oral antibiotic prescriptions during pregnancy filled at the pharmacy was obtained and verified longitudinally. Information on intrapartum antibiotics, social, and lifestyle-factors was obtained by personal interviews. Results The prevalence of antibiotic use was 37% during pregnancy and 33% intrapartum. Lower maternal age at birth; adjusted odds ratio (aOR) 0.94, 95% CI, [0.90-0.98], p = 0.003 and maternal smoking; aOR 1.97, 95% CI, [1.07-3.63], p = 0.030 were associated with use of antibiotics for urinary tract infection during pregnancy. Maternal educational level (low vs. high), aOR 2.32, 95% CI, [1.24-4.35], p = 0.011, maternal asthma; aOR 1.99, 95% CI, [1.33-2.98], p < 0.001 and previous childbirth; aOR 1.80, 95% CI, [1.21-2.66], p = 0.004 were associated with use of antibiotics for respiratory tract infection during pregnancy. Lower gestational age; aOR 0.72, 95% CI, [0.61-0.85], p < 0.001, maternal smoking; aOR 2.84, 95% CI, [1.33-6.06], p = 0.007, and nulliparity; aOR 1.79, 95% CI, [1.06-3.02], p = 0.030 were associated with administration of intrapartum antibiotics in women giving birth vaginally. Conclusion Antibiotic administration during pregnancy and birth may be influenced by social and lifestyle-factors. Understanding such risk factors may guide preventive strategies in order to avoid unnecessary use of antibiotics.

Abstract
BACKGROUND Autism and Autism Spectrum Disorder (ASD) are complex neurodevelopmental disorders. Susceptibility is believed to be the interaction of genetic heritability and environmental factors. The synchronous rises in autism/ASD prevalence and paracetamol (acetaminophen) use, as well as biologic plausibility have led to the hypothesis that paracetamol exposure may increase autism/ASD risk. METHODS To explore the relationship of antenatal paracetamol exposure to ASD, population weighted average autism prevalence rates and paracetamol usage rates were compared. To explore the relationship of early neonatal paracetamol exposure to autism/ASD, population weighted average male autism prevalence rates for all available countries and U.S. states were compared to male circumcision rates - a procedure for which paracetamol has been widely prescribed since the mid-1990s. Prevalence studies were extracted from the U.S. Centers for Disease Control and Prevention Summary of Autism/ASD Prevalence Studies database. Maternal paracetamol usage and circumcision rates were identified by searches on Pub Med. RESULTS Using all available country-level data (n = 8) for the period 1984 to 2005, prenatal use of paracetamol was correlated with autism/ASD prevalence (r = 0.80). For studies including boys born after 1995, there was a strong correlation between country-level (n = 9) autism/ASD prevalence in males and a country's circumcision rate (r = 0.98). A very similar pattern was seen among U.S. states and when comparing the 3 main racial/ethnic groups in the U.S. The country-level correlation between autism/ASD prevalence in males and paracetamol was considerably weaker before 1995 when the drug became widely used during circumcision. CONCLUSIONS This ecological analysis identified country-level correlations between indicators of prenatal and perinatal paracetamol exposure and autism/ASD. State level correlation was also identified for the indicator of perinatal paracetamol exposure and autism/ASD. Like all ecological analyses, these data cannot provide strong evidence of causality. However, biologic plausibility is provided by a growing body of experimental and clinical evidence linking paracetamol metabolism to pathways shown to be important in autism and related developmental abnormalities. Taken together, these ecological findings and mechanistic evidence suggest the need for formal study of the role of paracetamol in autism.

Abstract
BACKGROUND Many studies have described the prescribing of drugs to pregnant women, but only very few have data concerning the periconceptional period specifically. AIM The aim of the study was to evaluate the incidence of exposure to teratogenic drugs during early pregnancy and to determine whether a safer drug exists. METHODS In a French health insurances database, we analyzed drugs prescribed during the period starting 1 month before and ending 2 months after the beginning of pregnancy between 1 January 2006 and 31 December 2007. Based on the Summary of Product Characteristics (SPC), drugs we considered were those 'contraindicated', 'not recommended', 'to be avoided', and 'possible' for use during the first trimester of pregnancy. For drugs 'contraindicated', we established if there were alternatives with similar efficacy for the mother and lower risk for the fetus. RESULTS Over a period of 2.25 years, 8754 drugs were prescribed to 1793 women starting 1 month prior to and ending 2 months after conception. Among these drugs, 20 (0.2%) were 'contraindicated', 195 (2.2%) were 'not recommended', and 1209 (13.8%) were 'to be avoided' during the first trimester of pregnancy. Twenty (1.1%) women received at least one drug that was 'contraindicated' during the first trimester, 171 (9.5%) received a drug that was 'not recommended' and 768 (42.8%) received a drug that was 'to be avoided'. At least one possible alternative was available for all except one 'contraindicated' drug. CONCLUSIONS During the highest teratogenic risk period, 1.1% of women received a contraindicated drug, despite existence of a safer alternative drug. This may be partly accounted for by physicians not being aware of the pregnancy at the time the drug was administered and could be reduced by adding a section entitled 'women of child-bearing potential' to the SPC.

Abstract
OBJECTIVE Phloroglucinol is used to prevent gastric, intestine or urogenital spasms. In France, many pregnant women are exposed to phloroglucinol for which no data are available about its use in pregnancy. The present study, using EFEMERIS database, investigates potential teratogenic risk of phloroglucinol in pregnancy. MATERIALS AND METHODS EFEMERIS is a database including prescribed and delivered drugs during pregnancy (data from Caisse Primaire d'Assurance Maladie of Haute-Garonne) and outcomes (data from Maternal and Infant Protection Service and from Antenatal diagnostic Centre). Women delivered from July 1st 2004 to June 30th 2008 in Haute-Garonne and registered in the French Health Insurance Service were included into EFEMERIS database. We compared pregnancy outcomes and newborn health between women exposed to phloroglucinol during organogenesis and non-exposed women. Malformations were classified according to Eurocat classification. RESULTS Five thousand one hundred and thirty-two newborns (12.7%) exposed during organogenesis to phloroglucinol were compared to 35,223 controls (non exposed newborns). The mean number of different drugs prescribed during the first trimester of pregnancy per woman was higher in women exposed to phloroglucinol than in non-exposed women (6.4 ± 4.3 versus 2.4 ± 3.3, P < 10(-4)). Among newborns, 126 (2.5%) had a malformation versus 804 (2.3%) in control newborns (OR=1.1, [0.9-1.3]). The present study was powered to find a 1.3 fold increase in the overall rate of major anomalies. DISCUSSION AND CONCLUSION This first epidemiologic study about phloroglucinol in pregnancy does not support evidence of a teratogenic risk for phloroglucinol in humans.

Abstract
PURPOSE To review the literature describing patterns of outpatient prescription drug use during pregnancy by therapeutic category, potential for fetal harm, and overall. METHODS We conducted a systematic review of peer-reviewed literature published from 1989 to 2010. We included studies evaluating individual-level exposures to prescription medicines during pregnancy. We selected only studies conducted in developed (Organization of Economic Co-operation and Development) countries and published in English. RESULTS Published drug utilization studies reveal wide variation in estimates of overall prescription drug use in pregnancy (27-93% of pregnant women filling at least one prescription excluding vitamins and minerals). Among studies of similar design, estimates were lowest in Northern European countries (44-47%) and highest in France (93%) and Germany (85%). Measured rates of use of contraindicated medicines in pregnancy ranged from 0.9% (Denmark, 1991-1996) to 4.6% (USA, 1996-2000). The use of medicines with positive evidence of risk ranged from 2.0% (Italy, 2004) to 59.3% (France, 1996). CONCLUSION Avoidable inconsistencies in study design and reporting attenuate conclusions that can be drawn from the literature on antenatal drug utilization. Nevertheless, the body of published research shows that antenatal prescription drug use is common, with many studies finding that a majority of women use one or more prescription medicine during pregnancy. Similarly, studies consistently report the use of drugs recognized as having potential risks in pregnancy. Given this widespread use, it is particularly important to develop standards for calculating and reporting antenatal exposures to improve the value of future research in this area.

Abstract
PURPOSE To describe the reimbursement databases available in France for pharmacoepidemiological research and their use. METHODS France has a publicly funded health system that systematically covers the population. Within this system, three main insurance schemes provide health services to citizens in France and each have their own reimbursement database. Together these three databases cover almost 97% of the French population (respectively for 54.5, 3.6, and 3.3 million individuals, and a total of 61.4 million individuals). Data in these concern patients, prescribers, all the medical acts reimbursed, prescription and undertaking of laboratory tests (but without results), private hospital data, partial public hospital data and vital status. Their use is regulated but access is free and the data are anonymous. PubMed and Scopus were searched for relevant studies published from January 1988 to June 2009. RESULTS 110 published studies were included. The topics and the study characteristics were extremely wide-ranging. The studies assessed patterns of drug use, have tested interventions, supported or improved prescribing practices, tested compliance with the French governmental Health guidelines, assessed physicians' prescribing practices and performed economic and cost-effectiveness assessments. The number of articles published increased greatly between 2002 and 2003. CONCLUSIONS The French reimbursement databases were greatly used over the last 20 years. They can provide data on exposure to drugs and can be used to study patterns of drug utilization although their limitations must be considered.

Abstract
Background The rationale for use of drugs during pregnancy requires a careful assessment as in addition to the mother, the health and life of her unborn child is also at stake. Information on the use of drugs during pregnancy is not available in Pakistan. The aim of this study was to evaluate the patterns of drug prescriptions to pregnant women in tertiary care hospitals of Pakistan. Methods This was a cross-sectional study conducted at five tertiary care hospitals of Pakistan. Copies of outpatient medicinal prescriptions given to pregnant patients attending the antenatal clinics were collected. The drugs were classified according to the pharmacological class and their teratogenic potential. Results All the pregnant women attending the antenatal clinics received a prescription containing at least one drug. A total of 3769 distinct prescriptions given to different women were collected. Majority of the women who received the prescriptions belonged to third trimester (55.4%) followed by second (33.6%) and first trimester (11.0%). On an average, each prescription contained 1.66 ± 0.14 drugs. The obstetricians at Civil Hospital, Karachi and Chandka Medical College Hospital, Larkana showed a tendency of prescribing lesser number of drugs compared to those in other hospitals. Anti-anemic drugs including iron preparations and vitamin and mineral supplements (79.4%) were the most frequently prescribed drugs followed by analgesics (6.2%) and anti-bacterials (2.2%). 739 women (19.6%) received prescriptions containing drugs other than vitamin or mineral supplements. Only 1275 (21.6%) of all the prescribed drugs (n = 6100) were outside this vitamin/mineral supplement class. Out of these 1275 drugs, 29 (2.3%) drugs were prescribed which are considered to be teratogenic. Misoprostol was the most frequently prescribed (n = 6) among the teratogenic drugs followed by carbimazole (n = 5) and methotrexate (n = 5). Twenty nine pregnant women (0.8% of all the women studied) were prescribed these teratogenic drugs. Conclusion Less than one percent of the pregnant women attending tertiary care hospitals in Pakistan are prescribed teratogenic drugs. The prescribing practices of Pakistani physicians are similar to those in western countries.

Abstract
Before a recommendation for antimalarial drug use in pregnancy is made, it is essential that we understand the potential risks involved and have mechanisms in place to monitor risk during treatment. This requires data on drug disposition during pregnancy and potential toxicological liabilities to the developing fetus and mother. In most cases this information is not available. We review the reproductive toxicology of the main antimalarial drug classes in use or under development. Preclinical data are presented if appropriate, but as human experience overrides such data, in instances in which preclinical studies do not correlate with the human experience the data are reviewed only briefly. Additionally, we highlight the lack of appropriate drug disposition data in pregnancy and suggest mechanisms that can be used to capture data on risk after drug treatment in pregnancy.

Abstract
Data required to asses the risk of a new drug regarding the normal course of pregnancy as well as embryo, fetal and neonate development, are often missing when a new product is launched. In such a situation, a risk management plan is to be developed by the industrial and validated by regulatory authorities. This risk management plan is to take into account the data benefits on the drug and its potential therapeutic use by women as being of childbearing age. The obtaining of post licence human data is to be built on many players, both private and public, involved in the data collection and evaluation. The setting up of such a network would allow them to join together and optimize their action by standardizing the data collected and their follow up. This should help to generate or rapidly respond to an alert, to conduct collaborative pharmacovigilance pharmacology studies.

Abstract
OBJECTIVES The purpose of this study was to examine the prescribing patterns of anti-emetics for pregnant women in Germany. METHOD A large, nation-wide German statutory sickness fund provided data of reimbursed prescriptions and personal data for all insured women giving birth between June 2000 and May 2001 (n = 41,293). The prescribed drugs were classified according to the Anatomical Therapeutic Chemical code. RESULT About 13.9% (n = 5,746) of all pregnant women received an anti-emetic prescription. Over 98.5% of these women were treated with anti-emetics that are considered safe. But only 27.8% received the recommended anti-histamine meclozine and 2.1% the safest drug pyridoxine. CONCLUSION As there are no official guidelines for the treatment of nausea and vomiting during pregnancy in Germany, many different drugs are used, sometimes ignoring effectiveness and even safety. Therefore, evidence-based guidelines for anti-emetic therapy are needed.

Abstract
OBJECTIVE The aim of this study was to determine the extent and patterns of antidepressant use before, during and after pregnancy in a large population in The Netherlands. METHODS Health care records and prescription data from one of the largest Dutch health insurance companies were analysed. The study cohort consisted of 29,005 women who had live births in the period between January 2000 and July 2003. Antidepressant drug use during a specified period was defined as there being a record of a prescription during that period. RESULTS During the first trimester of pregnancy 2% of all pregnant women of the study cohort were found to have taken antidepressants; in the second and third trimesters, this figure had dropped to 1.8% of all pregnancies. Antidepressant use before as well as during pregnancy was almost twofold higher in women over 35 years of age than in those under 35 years. Almost 60% of the women who used antidepressants before pregnancy stopped taking them in the first trimester, and a smaller number stopped thereafter. Of all women using antidepressants during pregnancy, one third started this medication during gestation. In the 3 months following delivery, the prevalence of antidepressant use was the same as before pregnancy (2.9%). There was no shift to benzodiazepines in the group of women who stopped taking antidepressants during pregnancy. Although paroxetine and fluoxetine were the most frequently used antidepressants among the study group, all modern antidepressants were used. CONCLUSION A considerable number of women are being exposed to antidepressants throughout pregnancy up until delivery. One consequence of this is that their newborns need special care and supervision during the first days of life. However, women who stop taking the medication may risk a relapse of their illness, and this may also have a negative effect on the child.

Abstract
PURPOSE Antibiotics are frequently prescribed drugs in pregnancy. The purpose of the study was to analyse the use, the potential risks and the determinants of systemic antibiotic prescriptions during pregnancy. METHODS A large, nation-wide acting German statutory sickness fund provided prescription data and personal data of 41,293 pregnant women. For this study, all prescriptions of systemic antibiotics (ATC: J01) dispensed to each woman during a 21-month period were analysed. We used the FDA risk classification system and enrolled a literature search to identify potentially harmful antibiotics. To investigate the impact of geographical and socio-economic determinants in antibiotic prescribing, a multivariate logistic regression model was performed. RESULTS Of the 41,293 women, 19.7% received at least one antibiotic drug during pregnancy. There was a shift to relatively safe and reduced antibiotic drug use during pregnancy. Prescribing of contraindicated antibactericals or potentially harmful drugs was seen in 521 women (1.3% of all women). In the logistic regression, being younger than 21 years (adjusted OR 2.14, 95%CI 1.80-2.53) or being welfare recipient (adjusted OR 1.57, CI 1.25-2.00) was strongly associated with higher antibiotic use. Significantly lower antibiotic use was seen in 5 of 16 German federal states (OR 0.74-0.83). CONCLUSIONS About 20% of pregnant women received antibiotics, and 1.3% received a harmful drug. To minimise the risks, detailed guidelines are needed for the antibiotic treatment during pregnancy.

Abstract
OBJECTIVE To examine the prescription of drugs in Germany prior to, during and after pregnancy. METHODS For the first time, prescription data of a large cohort of pregnant women, from a German statutory sickness fund, were available for scientific analysis. For each woman who gave birth between June 2000 and May 2001 reimbursed prescriptions for two periods (90 days each) before pregnancy, three during and two after delivery were considered. The drugs were classified according to the ATC code. RESULTS Of the 41,293 women, 96.4% received at least one drug during pregnancy. A median of 7 drugs per women was prescribed. Excluding vitamins, minerals, iodide and iron, 85.2% received at least one drug and the median was 3. Magnesium, which was seldom prescribed outside of pregnancy, was by far the most frequently prescribed substance (20% of all prescriptions, 61% of the women). Iron (54% of the women) and iodide (31%) were also prescribed often. The prescription rates of gynaecological antiinfectives (maximum in third trimester: 23% of the women), antacids (max. in third trim.: 11%), as well as antiemetics and antinauseants (max. in first trim.: 8%) during pregnancy considerably increased. A decrease was seen for analgesics, antiinflammatory and antirheumatic drugs, muscle relaxants, ophtalmologicals and anti-acne preparations, for example. Potential teratogenic drugs were prescribed to 1.3% of the women. CONCLUSION This analysis of a large nation-wide cohort of pregnant women showed that during pregnancy drugs were prescribed to most women, even when vitamins, minerals, iodide and iron were omitted. Magnesium and iron seemed to have been over-prescribed. On the other hand, the official recommendation for iodide substitution, to prevent thyroid diseases in mother and child, was insufficiently implemented. In our opinion, regular analysis of prescription data can identify potential harmful therapies and focal points where guidelines are needed and can check their implementation.
