Opiate Agonists

DrugDrug NameDrug Indication
DB00193TramadolTramadol is approved for the management of moderate to severe pain in adults.[FDA label] As an off-label indication, tramadol has been investigated to be used for the treatment of premature ejaculation.[A173986]
DB00295MorphineFor the relief and treatment of severe pain.
DB00318CodeineFor treatment and management of pain (systemic). It is also used as an antidiarrheal and as a cough suppressant.
DB00327HydromorphoneFor the relief of moderate to severe pain such as that due to surgery, cancer, trauma/injury, or burns.
DB00333MethadoneFor the treatment of dry cough, drug withdrawal syndrome, opioid type drug dependence, and pain.
DB00454MeperidineUsed to control moderate to severe pain.
DB00497OxycodoneFor the treatment of diarrhoea, pulmonary oedema and for the relief of moderate to moderately severe pain.
DB00708SufentanilThe indications for this drug are as follows: 1. As an analgesic adjunct in the maintenance of balanced general anesthesia in patients who are intubated and ventilated. 2. As a primary anesthetic agent for the induction and maintenance of anesthesia with 100% oxygen in patients undergoing major surgical procedures, in patients who are intubated and ventilated, such as cardiovascular surgery or neurosurgical procedures in the sitting position, to provide favorable myocardial and cerebral oxygen balance or when extended postoperative ventilation is anticipated. 3. For epidural administration as an analgesic combined with low dose (usually 12.5 mg per administration) bupivacaine usually during labor and vaginal delivery 4. The sublingual form is indicated for the management of acute pain in adults that is severe to warrant the use of an opioid analgesic in certified medically supervised healthcare settings, including hospitals, surgical centers, and emergency departments. [FDA label]
DB00714ApomorphineFor the acute, intermittent treatment of hypomobility, off episodes (end-of-dose wearing off and unpredictable on/off episodes) associated with advanced Parkinson's disease.
DB00802AlfentanilFor the management of postoperative pain and the maintenance of general anesthesia.
DB00813FentanylFor the treatment of cancer patients with severe pain that breaks through their regular narcotic therapy.
DB00899RemifentanilFor use during the induction and maintenance of general anesthesia.
DB01192OxymorphoneFor the treatment of moderate-to-severe pain.
DB06204TapentadolThe immediate-release formulation of tapentadol is indicated for the relief of moderate to severe acute pain. The long-acting formulation serves as a continuous, around-the-clock analgesic that is indicated for the relief of moderate to severe chronic pain or neuropathic pain associated with diabetic peripheral neuropathy.
DB11130OpiumOpium and its derivatives are the most commonly used medications for the treatment of acute and chronic pain. Opium and its alkaloid-derivatives can also be used as tranquilizers, antitussives and in the treatment of diarrhea.[T138] The direct use of opium is not common nowadays but the use of some of its derivatives such as morphine and codeine, as well as the use of a tincture of opium for severe diarrhea can be seen in medical practice.[T139] Illegal use of opium has been registered to be for both recreational and medicinal purposes.[A32182]
