Methoxyphenamine inhibits basal and histamine-induced nasal congestion in anaesthetized rats
Br J Pharmacol 1990 Oct;101(2):394-8.PMID:1701679DOI:10.1111/j.1476-5381.1990.tb12720.x.
1. Nasal resistance in anaesthetized rats was assessed by measuring air overflow during ventilation of the nasal passages at constant pressure. Nasal basal resistance was reduced in a dose-dependent manner by Methoxyphenamine hydrochloride (0.01-30 mg kg-1, i.v.), pseudoephedrine hydrochloride (0.03-3 mg kg-1, i.v.) and adrenaline bitartrate (0.01-3 micrograms kg-1, i.v.). Both methoxyphenamine and pseudoephedrine were less potent and less efficacious than adrenaline but caused longer-lasting responses. 2. Nasal congestion induced by histamine (0.2% nebulised solution passed into the nasal passages for 15 s) was inhibited by i.v. administration of methoxyphenamine, pseudoephedrine, adrenaline, methoxamine or tyramine: the ID50s against 0.2% histamine-induced nasal congestion were 1.16 (95% confidence limits; 0.5, 1.8) mg kg-1, 0.25 (0.19, 0.33) mg kg-1, 0.037 (0.018, 0.06) micrograms kg-1, 8.12 (6.74, 9.65) micrograms kg-1 and 30.6 (26.1, 35.8) micrograms kg-1 respectively. 3. The inhibitory effects of both methoxyphenamine and tyramine on histamine-induced nasal congestion were reduced after administration of desmethylimipramine (0.1 and 1 mg kg-1, i.v.) or prazosin (0.1 and 0.3 mg kg-1, i.v.). Similarly, the inhibitory effects of methoxamine were reduced after prazosin (0.1 and 0.3 mg kg-1). 4. These results indicate that methoxyphenamine (1 mg kg-1, i.v.) inhibits histamine-induced nasal congestion in the rat. This action, at least in part, is probably indirect being mediated by release of neuronal noradrenaline which then acts on alpha 1-adrenoceptors.
HPLC determination of aminophylline, Methoxyphenamine hydrochloride, noscapine and chlorphenamine maleate in compound dosage forms with an aqueous-organic mobile phase
J Pharm Biomed Anal 2003 Sep 15;33(1):39-43.PMID:12946529DOI:10.1016/s0731-7085(03)00352-2.
A high-performance liquid chromatography procedure for the simultaneous determination of aminophylline, Methoxyphenamine hydrochloride, noscapine and chlorphenamine maleate in commercially available compound capsule dosage forms has been developed and validated. The separation and quantification were achieved on an Ultrasphere C18 column using a mobile phase of dichloromethane-methanol-0.25% (v/v) diethylamine aqueous solution (20:60:20, v/v/v) at a flow rate of 1 ml min(-1) with detection of all analytes at 264 nm. The separation was achieved within 6 min for each drug mixture. The method showed good linearity for the aminophylline, noscapine, chlorphenamine maleate and Methoxyphenamine hydrochloride mixture in the 125-750, 35-210, 10-60 and 62.5-375 microg ml(-1) ranges, respectively. The intra- and inter-day R.S.D.s ranged from 0.4 to 0.5%, 0.4-0.6%, 0.5-0.7% and 0.4-0.6% for aminophylline, noscapine, chlorphenamine maleate and Methoxyphenamine hydrochloride, respectively. The recoveries (mean+/-S.D.) of low, middle and high concentrations were 99.9+/-0.9, 100.4+/-1.3 and 99.7+/-0.7% for aminophylline; 99.9+/-1.1, 100.4+/-0.7 and 100.1+/-0.8% for noscapine; 99.8+/-1.1, 99.7+/-1.0 and 100.7+/-0.8% for chlorphenamine maleate; and 99.8+/-0.9, 100.4+/-1.6 and 99.9+/-0.9% for Methoxyphenamine hydrochloride, respectively.
Gas chromatographic quantitation of methoxyphenamine and three of its metabolites in plasma
J Chromatogr 1984 Oct 12;310(2):307-17.PMID:6150940DOI:10.1016/0378-4347(84)80095-x.
Sensitive gas chromatographic procedures for the determination of methoxyphenamine and three of its metabolites in plasma have been developed. The metabolites were measured using an electron-capture detector. This simple procedure is based on the precipitation of protein from a 1-ml plasma sample with 10% trichloroacetic acid, followed by aqueous derivatization with pentafluorobenzoyl chloride at pH 9.2 and a single-step cyclohexane extraction. The lower limit of detection for the N-desmethyl, O-desmethyl and aromatic 5-hydroxy metabolites of methoxyphenamine were 1.6, 3.1 and 2.2 ng ml-1, respectively, with coefficients of variation less than 10%. The poor electron-capture response of fluorinated derivatives of methoxyphenamine necessitated the use of nitrogen-phosphorus detection. Extractive derivatization with pentafluorobenzoyl chloride, without the need for protein precipitation, enabled quantitation of methoxyphenamine down to 3.8 ng ml-1 from a 2-ml aliquot of plasma. In a pilot study involving healthy volunteers who received a single oral dose of Methoxyphenamine hydrochloride plasma concentration could be followed in all three subjects for at least 24, 32, 12 and 4 h for methoxyphenamine and the O-desmethyl, 5-hydroxy and N-desmethyl metabolites, respectively.
Methoxyphenamine inhibits histamine-induced bronchoconstriction in anaesthetized guinea-pigs and histamine-induced contractions of guinea-pig ileum in vitro
Arch Int Pharmacodyn Ther 1990 Nov-Dec;308:86-94.PMID:1983067doi
Measurements were made of the effects of Methoxyphenamine hydrochloride on histamine-, acetylcholine- and U46619-induced bronchoconstriction in pentobarbitone-anaesthetized guinea-pigs, and on histamine- and acetylcholine-induced contractions of guinea-pig ileum in vitro. Methoxyphenamine (20 mg/kg, i.v.) did not affect bronchoconstriction induced by acetylcholine or the thromboxane A2-mimetic U46619. However, it produced a parallel rightward shift [2.94-(1.79, 4.41) fold, 95% confidence limits in parentheses] of the curve relating bronchoconstrictor responses to log-dose of histamine at a total dose of 13 mg/kg, i.v., which was not significantly different from the shift [3.30-(1.93, 5.56) fold] produced by 3 micrograms/kg, i.v., of the histamine antagonist mepyramine maleate. Histamine-induced contractions of the isolated guinea-pig ileum were antagonized by methoxyphenamine (10(-5) to 10(-3) M). The histamine log-concentration-response curve was shifted to the right in a parallel manner by methoxyphenamine (10(-5) to 10(-4) M), without depression of maximum responses. However, at higher concentrations, maximum responses were reduced. The slope of the Schild plot was significantly different from -1. The degree of the rightward shift of the concentration-response curves to histamine, produced by 10(-5) M of methoxyphenamine [3.90-(2.83, 4.97) fold], was not significantly different from that produced by 3 x 10(-9) M of mepyramine [4.60-(2.86, 6.52) fold]. Methoxyphenamine, at concentrations of 10(-5) to 3 x 10(-4) M, had no significant effect on responses of guinea-pig ilea to acetylcholine (10(-9) to 10(-5) M). These results indicate that methoxyphenamine antagonizes the effects of histamine both in vivo and in vitro. In vitro studies indicate a noncompetitive antagonism.
