Study Notes

Morphine Sulfate Preparations and Doses

Administered as 10 mg subcutaneously or intramuscularly; 5 mg intravenous in acute myocardial infarction.
Intrathecal (epidural) injection provides long-lasting analgesia, particularly beneficial for critically ill patients prone to respiratory depression.
Available in sustained release formulations and transdermal patches.

Adverse Effects

CNS Effects
- Prolonged use can lead to tolerance and physical dependence; physical dependence may develop within 24 hours with use every 4 hours.
- Tolerance develops for analgesia and euphoria but not for respiratory depression.
- Increased intracranial tension and dose-dependent respiratory depression are notable risks.
Respiratory System
- Bronchoconstriction is a potential adverse effect.
Cardiovascular System
- May cause postural hypotension.
Gastrointestinal Tract
- Common effects include nausea, vomiting, constipation, increased biliary tract pressure, and potential biliary colic.
Genitourinary System
- Urinary retention can occur especially in patients with enlarged prostates; may prolong labor.
Ocular Effects
- Miosis is a consistent sign of morphine addiction.

Contraindications and Precautions

Contraindicated in head injuries and conditions with increased intracranial pressure due to risk of respiratory depression and CO2 retention.
Not suitable for patients with bronchial asthma because it can induce bronchoconstriction, respiratory depression, and histamine release.
Use caution in patients with biliary colic or gallstones as morphine can increase biliary pressure.
Patients with senile enlarged prostate may experience urinary urgency and difficulty urinating due to increased detrusor muscle tone.
Hypotension risks due to the potential for postural hypotension.
Contraindicated in hepatic damage due to metabolic processing in the liver and increased CNS depression.
Patients with hypothyroidism or adrenal insufficiency may have exaggerated responses to morphine.
Should not be used in cases of undiagnosed acute abdominal pain as it can mask symptoms and delay diagnosis.
Infants and elderly individuals are at greater risk for respiratory depression.

Chronic Opioid Toxicity

Symptoms include behavioral changes, constipation, itching, and miosis.
Sudden withdrawal may lead to irritability, nervousness, tremors, hypertension, and muscle cramps starting 6-10 hours after the last dose, peaking at 48 hours and subsiding over 5-10 days.
Mechanism involves chronic opioid use decreasing endogenous endorphin and norepinephrine levels, leading to withdrawal symptoms due to sudden deficiency of endogenous opioids.

Treatment of Chronic Morphine Addiction

Should include gradual withdrawal of morphine, substituted with methadone, followed by a gradual tapering off methadone.
Clonidine can be used to stimulate central alpha-2 receptors, reducing norepinephrine release.
Sedatives like diazepam may aid in managing symptoms during withdrawal.

Acute Opioid Toxicity

Signs include coma, depressed respiration, miosis, and shock; death typically results from respiratory depression.
Treatment involves gastric lavage, ensuring a patent airway, and providing artificial respiration as necessary.
