This risk may vary among different oral contraceptives due to the progestin component. Studies evaluated showed that women utilizing a drospirenone-containing COC did not have a higher risk of VTE when compared to women utilizing other progestins. The crude incidence rate ratio for VTE in women taking a COC containing drospirenone compared to a COC containing other progestins ranged from 0.9 to 1.7 (95% CI 0.5 to 2.4). While the studies evaluating VTE risk were mostly large and long term, most failed to consider important risk factors for VTE such as prolonged immobility, obesity, smoking history, and family history of VTE (which could suggest a genetic predisposition to thrombotic events). It was also unclear with some of the studies whether equivalent estrogen doses were used in the comparisons.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>Several studies have evaluated the risk of VTE in users of COC-containing drospirenone compared with other progestins, and none were able to show a significantly increased risk of VTE with drospirenone. The recent media attention regarding VTE risk and drospirenone-containing COCs does not seem to be well supported by the research currently available.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1345\/aph.1m649","type":"journal-article","created":{"date-parts":[[2010,4,7]],"date-time":"2010-04-07T01:43:42Z","timestamp":1270604622000},"page":"898-903","source":"Crossref","is-referenced-by-count":21,"title":["Risk of Venous Thromboembolism with Drospirenone in Combined Oral Contraceptive Products"],"prefix":"10.1177","volume":"44","author":[{"given":"Naida","family":"Sehovic","sequence":"first","affiliation":[{"name":"Naida Sehovic, PharmD Student, University of Southern Nevada College of Pharmacy, South Jordan, UT"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katherine P","family":"Smith","sequence":"additional","affiliation":[{"name":"Katherine P Smith PharmD BCPS, Director of Continuing Education, Associate Professor of Pharmacy Practice, University of Southern Nevada College of Pharmacy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2010,5,1]]},"reference":[{"key":"bibr1-aph.1M649","unstructured":"World Health Organization.
