The respiratory stimulatory effect of 3'chloro-2'-(N-methyl-N-[(morpholino-carbonyl)methyl]-aminomethyl)benzanilide hydrochloride (fominoben, Noleptan, PB 89) on the respiratory-depressing effect of pethidine/promethazine was investigated. In addition a double blind study was carried out on 36 patients with fominoben or placebo after pethidine/promethazine. To evaluate respiratory function the vital capacity, Tiffeneau-value, volume of inhaled air/s, maximum breathing capacity, as well as the blood gas values (pO2, pCO2 and pH according to Astrup) were measured. The results can be summarised as follows: 1. As was to be expected the combination pethidine/promethazine caused a deterioration in all parameters. This negative effect could be partially improved by fominoben. 2. A marked difference in the volume of inhaled air/s could be seen after fominoben in comparison to the placebo. The remaining differences were insignificant. 3. Pethidine/promethazine had, as had been expected, a significant effect on pain symptoms, but no analgetic effect could be shown for fominoben.

Pentazocine (Fortral) suppositories (50 mg) were compared with pethidine (100 mg) by injection in 500 patients after general and gynaecological surgery. Pain was assessed by patients using a pain thermometer, (a modification of a visual analogue scale), and by observers using an adjectival scale. There was a good relationship between these methods. Good pain relief was obtained with both drugs and there was little difference between the treatments in moderate pain. Pethidine was faster and more effective, particularly in severe pain. There were fewer side-effects with pentazocine suppositories. They are a useful alternative to injections, especially in moderate pain.

We have previously reported 10 patient histories involving various intractable pain syndromes where the administration of Haloperidol either eliminated the need for narcotic analgesics or resulted in a significant reduction in narcotic dosage. We are presently undertaking a controlled double-blind evaluation of Haloperidol as an adjunctive treatment for intractable cancer pain. Based upon the reported clinical observations, these findings are discussed from the following aspects: 1. The isomeric similarity of Haloperidol to Meperidine. 2. Dose response between Haloperidol and analgesic effect. 3. The clinical literature regarding the use of Haloperidol for the effective withdrawal or maintenance of narcotic addicts. 4. The analgesic property as it relates to the opiate receptor.

A double-blind, between-patient, two-dose comparison was comparison was performed with pethidine and nefopam in 100 subjects, the majority of whom were recovering from upper abdominal surgery. Either 15 or 30 mg of nefopam or 50 or 100 mg of pethidine were given by i.m. injection in a random order. All assessments were made by the same observer on the first day after operation, at least 4 h after the previous analgesic injection. Nefopam 15 mg was equipotent with pethidine 50 mg, peak analgesia being achieved 1 h after the i.m. injection. Pethidine 100 mg provided significantly better pain relief than nefopam 30 mg, the latter being not more effective than nefopam 15 mg apart from the duration of analgesia which was longer. The incidence of nausea and vomiting was similar after both drugs. Sweating and tachycardia were observed more frequently after nefopam, whereas sedative side-effects were more common after pethidine.

Pethidine is commonly used in single doses as a preoperative medication or in multiple doses as an analgesic. The clinical consequences of altered disposition are more likely to result from its analgesic use. Correlations between plasma pethidine concentration, analgesia and side effects such as respiratory depression, have been established, but considerable overlap exists between concentrations producing therapeutic and non-therapeutic effects. The current practice of intermittent pethidine administration (intravenous, intramuscular and oral) for analgesia results in fluctuations in pethidine plasma concentrations which are associated with incomplete pain relief and side effects. Continuous intravenous infusion of pethidine may avoid these difficulties. Changes in pethidine disposition have been observed in patients with liver disease and in the elderly. Measurement of plasma pethidine concentrations may be helpful as an aid to the management of such patients. In renal disease, metabolites may accumulate and cause side effects.

Anileridine and pethidine have a spasmolytic action on animal intestine. Pethidine is known to have a spasmogenic effect at the choledocho-duodenal junction of man, but there is no study of the effect of anileridine on the biliary tract. In the present study the effects of anileridine and pethidine on the intracholedochal pressure during constant fluid perfusion in man were compared. The maximal elevation of the choledochal passage pressure was significantly greater after anileridine than after pethidine. However, the difference between anileridine and pethidine seemed to be less than that reported previously between morphine and pethidine. The effect of anileridine was of shorter duration than of pethidine. Anileridine and pethidine are not ideal analgesics when the normal activity of the biliary ductal system has to be maintained in pain or during cholangiography.

An analytical procedure for the simultaneous determination of pethidine and its N-Demethylated metabolite, norpethidine, in plasma is described. Pethidine and norpethidine are separated by partition chromatography, converted to the trichloroethyl carbamate with trichloroethyl chloroformate and determined by electron capture gas chromatography. The smallest amounts of pethidine and norpethidine determined by the method were 10 and 2 ng, respectively, in 0.1 ml plasma. The relative standard deviation in the determination of 50 ng of pethidine and 40 ng of norpethidine in 0.1 ml plasma wwere 5.8% (n = 8) and 6.3% (n = 10), respectively. The method was used to determine plasma levels of pethidine and norpethidine in three patients who received subcutaneous doses of pethidine 50-75 mg for postoperative pain. The peak levels of pethidine were found to be in the range 200-400 ng/ml, with a plasma half-life of the order of 4 hours. The levels of norpethidine were low.

In a restricted sequential trial in healthy parturient women, the pain relief from pethidine 100 mg and pethidine 100 mg combined with naloxone 0.4 mg was compared. Pethidine alone gave better relief. The incidence of minor side-effects was high with both treatments but dizziness was reduced slightly by naloxone. It was concluded that naloxone antagonized the analgesia without abolishing the side-effects of pethidine.

A linear analogue for rating pain with 10, 15 and 20 cm lines is significantly less variable than a 5 cm line (mean error of 15 cm line is 0-19%, 95% confidence limits for the group +/- 2% and an inood correlation between repeated ratins of a recalled pain distant in time. The variance of the rating is significantly less than the repeated rating of a random mark. The linear analogue rating of a constant pain stimulus is reproducible and changes in rating are likely to be real changes of opinion. Pethidine 150 mg intramuscularly had no significant effect, tested 30 minutes after the administration, on the accuracy or reproducibility of the analogue rating. A linear analogue seems a suitable method of recording the patient's opion of a severe pain such as that of labour.

Premedication is one of the popular techniques in anesthesia, not only for the decrease of side effects but also for the increase of actions. Clinically, we found that plasma neuropeptide Y-like immunoreactivity (NPY-IR) was lowered in patients who had received premedication. In rats, plasma NPY-IR was not modified by the intravenous injection of diazepam. Pethidine reduced the plasma NPY-IR level which could be reversed by naloxone. Direct inhibition of plasma NPY-IR through an activation of opioid receptors can thus be considered. To the cold-stress stimulation, plasma NPY-IR was markedly raised. Diazepam reduced this stimulation-induced increase of plasma NPY-IR in a dose-dependent manner. Similar derivative of benzodiazepine produced an inhibition in a way following the potency as that to produce anxiolytic action. Also, this inhibition was reversed by PK11195, an antagonist of peripheral benzodiazepine receptors. Moreover, pain-stimulated increase of plasma NPY-IR in rats was also reduced by pethidine. This action was totally reversed in the presence of naloxone, indicating the participation of opioid receptors in the process. The obtained results suggest that premedication of diazepam and/or pethidine has the ability to decrease plasma NPY-IR in animals.
