It&#8217;s a prodrug metabolized in the liver (primarily by CYP2D6 enzyme) into morphine, which provides its main analgesic and antitussive effects. Chemically, it&#8217;s C\u2081\u2088H\u2082\u2081NO\u2083\u00b7H\u2083PO\u2084, with a molecular weight of 406.37 g\/mol.<\/p>\n<p class=\"mb-2 last:mb-0\"><strong>Medical Uses<\/strong><\/p>\n<ul>\n<li><strong>Pain relief<\/strong>: Codeine Phosphate mild to moderate pain (e.g., headaches, dental pain, post-surgical). Often combined with acetaminophen (e.g., Tylenol #3) or ibuprofen.<\/li>\n<li><strong>Cough suppression<\/strong>: In antitussive syrups (e.g., for dry coughs).<\/li>\n<li><strong>Diarrhea treatment<\/strong>: In some formulations like Lomotil (with diphenoxylate). Doses typically range from 15\u201360 mg every 4\u20136 hours for adults (max 360 mg\/day), but always under medical supervision.<\/li>\n<\/ul>\n<p class=\"mb-2 last:mb-0\"><strong>Pharmacology<\/strong><\/p>\n<\/div>\n<div class=\"overflow-x-auto my-4\">\n<table class=\"markdown-table\">\n<thead>\n<tr>\n<th>Property<\/th>\n<th>Details<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Class<\/td>\n<td>Opioid agonist (\u03bc-receptor partial agonist)<\/td>\n<\/tr>\n<tr>\n<td>Onset<\/td>\n<td>30\u201360 minutes (oral)<\/td>\n<\/tr>\n<tr>\n<td>Duration<\/td>\n<td>4\u20136 hours<\/td>\n<\/tr>\n<tr>\n<td>Half-life<\/td>\n<td>2.5\u20134 hours (varies by metabolism; poor CYP2D6 metabolizers get less effect)<\/td>\n<\/tr>\n<tr>\n<td>Bioavailability<\/td>\n<td>~50% oral (first-pass metabolism)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<div class=\"prose break-words dark:prose-invert prose-p:leading-relaxed prose-pre:p-0 fix-max-with-100 prose-p:!mt-0\">\n<p class=\"mb-2 last:mb-0\"><strong>Side Effects &amp; Risks<\/strong><br \/>\nCommon: Drowsiness, constipation, nausea, dizziness.<br \/>\nSerious: Respiratory depression, addiction potential (Schedule II in US, varying elsewhere), overdose risk (especially with alcohol\/benzos).
