Hydromorfonhydroklorid Kalceks (Hydromorphone Hydrochloride)

Hydromorphone Hydrochloride is an opioid analgesic used to manage pain in the central nervous system.

• Moderate to severe acute pain: provides rapid analgesia for sudden, intense pain episodes.
• Post‑operative pain: reduces discomfort following surgical procedures, facilitating recovery.
• Cancer‑related pain: helps control persistent severe pain associated with malignancies.
• Chronic severe pain: maintains long‑term pain control when other therapies are insufficient.
• Traumatic injury pain: alleviates intense pain resulting from serious injuries.

• Hydromorphone Hydrochloride exerts its effect by binding as a full agonist to the μ‑opioid receptors in the central nervous system. Activation of these G‑protein‑coupled receptors inhibits adenylate cyclase, reduces calcium influx, and increases potassium efflux, which together diminish neuronal excitability and block transmission of nociceptive signals, producing analgesia and sedation.

Hydromorphone Hydrochloride may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Nausea: feeling of sickness or urge to vomit, often transient.
• Drowsiness: increased sleepiness or fatigue that may affect alertness.
• Constipation: reduced bowel movements, frequently requiring laxative support.
• Dry mouth: decreased salivation leading to discomfort.

Serious or Rare Side Effects

• Respiratory depression: slowed or shallow breathing that can be life‑threatening.
• Hypotension: significant drop in blood pressure, potentially causing dizziness.
• Allergic reaction: rash, itching, swelling, or anaphylaxis requiring immediate medical attention.

When using Hydromorphone Hydrochloride, several precautions should be observed to ensure safe administration.

• Assess pain level: confirm that opioid therapy is appropriate for the patient.
• Monitor respiratory function: watch for signs of respiratory depression, especially after dose changes.
• Avoid concurrent CNS depressants: limit use with benzodiazepines or alcohol.
• Adjust dose in renal/hepatic impairment: reduce dosage as needed based on organ function.
• Pregnancy and lactation: use only if benefits outweigh potential risks.
• Store at ambient temperature: keep in original container, protect from moisture and light.

Hydromorphone Hydrochloride can interact with other medications, altering its efficacy or safety profile.

Major Interactions (Avoid)

• Other opioids: additive risk of respiratory depression.
• Benzodiazepines or barbiturates: increased sedation and respiratory compromise.
• MAO inhibitors: potential for severe hypotension and serotonin syndrome.

Moderate Interactions (Monitor Closely)

• Anticholinergics: may exacerbate constipation.
• CYP3A4 inhibitors (e.g., ketoconazole): increase hydromorphone plasma levels.
• CYP3A4 inducers (e.g., rifampin): decrease hydromorphone plasma levels.
