Abstract


Background: High-risk pregnancy is an important determinant of drug use during pregnancy. The aim of study was to evaluate drug use pattern according to WHO core-drug prescribing indicators and US-FDA pregnancy category in indoor patients of high-risk pregnancy.

Methods: It was a prospective, observational study. All high-risk pregnant women admitted to tertiary care hospital and willing to give consent were included. The data was collected from 290 patients over 12 months. The data was analysed to evaluate drug utilization according to WHO core drug use indicators and in relation to US-FDA pregnancy risk category.

Results: The study found that 74.82% of women were between 20-30 years of age and were admitted during third trimester of pregnancy. The most commonly prescribed drug class was vitamins and minerals prescribed in 82.75% patients. Average number of drugs per encounter was 6.4. Percentage of drugs prescribed by generic name and from essential drug list was 73.07% and 77.07% respectively. Percentage of encounters with an antibiotic and an injection prescribed was 29.31% and 65.17% respectively. The prescription of drugs belonging to US-FDA pregnancy drug categories A, B and C were 92.06%, 86.55% and 4.82% respectively.

Conclusions: Overall, the principles of rational prescribing were followed according to the various drug use indicators mentioned by the WHO and US FDA pregnancy risk category. Further studies are required to find out specific drug or drug therapy related problems and plan targeted interventions to improve drug use.
