<p><strong>Misoprostol</strong> is a drug that is FDA-approved in the United States for the prevention of NSAID-induced gastric ulcers. It is also used (and approved in other countries) to induce labor and as an abortifacient. It was invented and marketed by G.D. Searle & Company (now Pfizer) under the trade name <strong>Cytotec</strong>, but other brand-name and generic formulations are now available as well.</p>
<p>Chemically, misoprostol is a synthetic prostaglandin E<sub>1</sub> (PGE<sub>1</sub>) analogue.</p>
