It has been reported! by Simon 1) that several synthetic analogs of the morphine series are strong inhibitors of bacterial growth. Simon attributes this effect to selective inhibition of ribosomal RNA synthesis (2, 3). We have studied the effects of the most potent of these drugs, levallorphan tartrate, on macromolecular synthesis in Escherichia coli. This d!rug was selected for study because i...

Dopamine along with other chemical messengers like serotonin, cannabinoids, endorphins and glutamine, play significant roles in brain reward processing. There is a devastating opiate/opioid epidemicin the United States. According to the Centers for Disease Control and Prevention (CDC), at least 127 people, young and old, are dying every day due to narcotic overdose and alarmingly heroin overdos...

OBJECTIVE Physicians may prescribe buprenorphine for opioid agonist maintenance treatment outside of narcotic treatment programs, but treatment guidelines for patients with co-occurring cocaine and opioid dependence are not available. This study compares effects of buprenorphine and methadone and evaluates the efficacy of combining contingency management with maintenance treatment for patients ...

The treatment of pain in acute myocardial infarction varies with local practice. Narcotic analgesics are still the usual treatment in many hospitals. Knowledge of optimal doses, duration of pain relief, and time between drug administration and pain relief is inadequate. Many studies indicate that the relief of pain is often incomplete after' treatment with narcotic analgesics. There is often a ...

IT HAS BEEN XaEt'ORTED that, when administered alone, the hvo clinically available narcotic antagonists, nalorphine hydrochloride (Nalline) 1-7 and levallorphan tartrate, 8-1~ have respiratory and circulatory effects similar to those of narcotics. When a third potent narcotic antagonist, naloxone hydrochloride, became available for experimental use, it seemed worthwhile to compare the respirato...

Morphine inhibits adenylate cyclase (EC 4.6.1.1) activity of neuroblastoma times glioma hybrid cells. The inhibition is stereospecific and is reversed by the antagonist, naloxone. The relative affinities of narcotics for the opiate receptor agree well with their effectiveness as inhibitors of adenylate cyclase. Morphine-sensitive and -insensitive cell lines were found, and the degree of sensiti...
