Morfina sulfate 30 mg is a potent opioid analgesic commonly available in immediate-release (IR) oral tablets, extended-release (ER) formulations (e.g., MS Contin), or other forms like injections. Here’s a factual breakdown based on standard pharmacological data (e.g., from FDA labels, USP, and medical references like Lexicomp):

Los Usos Principales

• Primario: Moderate to severe pain relief (e.g., post-surgical, cancer pain, acute injury).
• Otro: Sometimes for severe dyspnea in palliative care or cough suppression.
• 30 mg dose context:

Farmacocinética

• Biodisponibilidad: ~20-30% oral (first-pass metabolism); 100% IV.
• Vida media: 2-4 hours (normal renal/hepatic function).
• Equianalgesic dose: 30 mg oral IR ≈ 10 mg IV/IM ≈ 30 mg rectal.

Dosing Guidelines (Adults)

• Niños: Weight-based (0.05-0.2 mg/kg IV); not for <2 yrs typically.
• Conversion: From other opioids, use calculators like those from MDCalc (e.g., 30 mg morphine oral = 10 mg IV).

Efectos secundarios y riesgos

• Contraindicaciones: Asma aguda, íleo paralítico, depresión respiratoria grave.
• Advertencias: High abuse potential (Schedule II controlled substance). Risk of addiction, overdose (esp. with benzos/alcohol). CDC guidelines recommend lowest effective dose/shortest duration.

Evidencia y fuentes

• Eficacia: Supported by RCTs (e.g., WHO pain ladder); 30 mg IR provides ~70-90% pain reduction in opioid-naive patients (JAMA reviews).
• References: FDA label (morphine sulfate), UpToDate, Micromedex. For calculations: Opioid Equianalgesic Table (Palliative Care Network).
