Under normal circumstances, morphine hydrochloride sustained-release tablets have analgesic, antitussive, sedative, respiratory depressant, and miosis effects. It is recommended to consult a professional physician before use. Specific analysis is as follows:
1. Analgesia
Morphine hydrochloride sustained-release tablets act on opioid receptors in the central nervous system, particularly the μ-opioid receptors, inhibiting neuronal impulses triggered by harmful stimuli in the brain, thereby effectively relieving moderate to severe pain.
2. Antitussive effect
Morphine hydrochloride sustained-release tablets reduce coughing by constricting mucosal blood vessels in the respiratory tract and decreasing vagal nerve tone.
3. Sedation
Morphine hydrochloride sustained-release tablets reduce cortical excitability in the brain, leading to altered consciousness and producing a sedative effect.
4. Respiratory depression
Morphine hydrochloride sustained-release tablets suppress the respiratory center, reducing its responsiveness to carbon dioxide tension. Overuse may lead to respiratory failure.
5. Miosis (pupil constriction)
Morphine hydrochloride sustained-release tablets block the action of norepinephrine on the pupillary sphincter muscle, resulting in pupil constriction.
If this medication is needed, it should be used under the guidance of a qualified physician to avoid unnecessary physical harm. In daily life, maintain regular and light eating habits, and avoid spicy or irritating foods such as Sichuan pepper, chili peppers, and onions, which are detrimental to health.
