The increased analgesia may be a result of not only the increase of serum/morphine concentrations but possibly also some alterations in the morphine receptors chloroquine 250mg amex treatment medical abbreviation. Acute administration of clomipramine potentiates morphine analgesia in mice whereas chronic administration attenuates them (52) cheap 250 mg chloroquine with visa medicine lodge treaty. Metabolism Opioid interaction on drug metabolism that reported are mostly in vitro or in experi- mental studies buy chloroquine 250mg with amex medical treatment 80ddb. The use of morphine in patients who are intoxicated with alcohol is especially dangerous and even small doses can be fatal when there is a high concentration in the blood (15) buy 250mg chloroquine with mastercard symptoms 16 weeks pregnant. However, age, gender, and other risk factors do not account for the strong age and gender patterns observed among victims of overdose. There is evidence that systemic diseases particularly pulmonary and hepatic disorders may be more prevalent in users who are at greater risk of overdose. There is no effective role for opiate mediation in ethanol intake as well as any ethanol sweet-fluid intake interactions (60). Both ethanol and opioids are metabolized in part by the hepatic mixed enzyme oxidative system. When both drugs are used together, slower disposal rates and possibly higher toxicity may arise. Ethanol may affect some opiate receptors and possibly change the brain tis- sue endogenous opiate peptide levels in some loci. Mixed alcohol and opiate abusers did poorly in standard alcohol abstinence treatment compared to matched alcoholics without opiate abuse histories (61). It has been found that rifampin was found to reduce morphine’s analgesic effects, probably due to the induction of its metabolism (62). Opioids and Opiates 137 fluvoxamine (and fluoxetine to a less extent) may cause an important increase in serum methadone concentrations (64). In patients unable to maintain effective methadone blood level throughout the dosing interval, fluvoxamine can help increase the methadone blood level and alleviate opiate withdrawal symptoms (65). The inhibition of differ- ent clusters of the cytochrome P450 system is involved in these interactions. Quinidine-induced inhibition of codeine O-demethylation is ethnically dependent with the reduction being greater in Caucasians (67). Ciprofloxacin may inhibit cytochrome P450 3A4 up to 65%, thus elevat- ing methadone levels significantly (68). The clearance of intravenous morphine (1 mg) was increased by 75%, oral morphine (10 mg) by 120% in six young women taking an oral contraceptive (70). This implies that the dosage of morphine will need to be virtually doubled to achieve the same degree of analgesia. Urinary morphine concentration will then be greater in patients taking oral contraceptives. In a study, the administration of ammonium chloride and sodium carbonate over 3 d each resulted in a mean methadone elimination half- 138 Moallem, Balali-Mood, and Balali-Mood life of 19. It was shown that haemodynamic changes induced by propofol may have an important influence on the pharmacokinetics of alfentanil (76). In 30 normal subjects, it was found that quinalbarbitone and morphine depressed ventilation when given alone. However, a combination of quinalbarbitone and morphine resulted in a much greater and more prolonged depression. Other respiratory depressant drugs such as narcotics, opiates, and analgesics can also have additive effects (77). In one study, it was found that fen- tanyl and alfentanil pretreatment have also reduced the dose of thiopental required for anesthesia induction (78). Also, the simultaneous administration of morphine and phenothiazines can result in significant hypotension (15). Alprazolam mediated analgesic effects, most probably via a µ opiate mechanism of action (79). For instance, sertaline increases the plasma methadone concentration significantly in depressed patients on methadone (80). Several lines of evidence suggest that benzodiazepines and methadone may have synergistic interactions and that opiate sedation or respiratory depression could be increased. In a study, meperidine and chlorpromazine com- pared to meperidine and placebo resulted in significantly increased lethargy and hypo- tension (81). Opiate abusers use amphetamines to in- crease the effects obtained from poor quality heroin (82). Braida and coworkers demonstrated that cannabinoids produce reward in conditioned place preference tests and interconnection of opioid and cannabinoid systems (83). Muscle Relaxants Patients recovering from relaxant anaesthesia are especially vulnerable to the respiratory depressant effects of morphine. Respiratory acidosis, secondary to acute hypercapnia, can result in reactivation of the long-acting relaxant on the completion of anesthesia, resulting in further depression of respiration. The combination of muscle relaxant and morphine could result in a rapidly progressing respiratory crisis (15). Adrenergic Drugs Agmatin (an endogenous polyamine metabolite formed by the carboxylation of L-arginine) potentiates antinociception of morphine via an alpha2 adrenergic receptor- mediated mechanism. This combination may be an effective therapeutic strategy for the medical treatment of pain (92). Yohimbine (an alpha2 antagonist) tends to limit opiate antinociception and the additive potential of µ and delta opioid agonists (93). Clonidine (4 and 10 µg/kg) in cats had a differential degree of inhibition in the order of analgesia, much greater than hypotension, greater than bradycardia. Fur- thermore, pain suppression of clonidine appeared to be independent of vasodepression and cardio inhibition (94). When administered with pentazocine, clonidine caused a statistically signif- icant increase in pentazocine analgesia (95). Clonidine induced dose- and time-depen- dent suprasensitivity to norepinephrine, similar to that produced by morphine. Thus, clonidine and morphine possess comparable properties on the antagonism of chronic morphine tolerance; and this maybe the therapeutic basis for clonidine’s clinical appli- cation in the treatment of opiate addicts (96). Heroin and Alcohol There have been numerous reports of the enhancement of acute toxicity and fatal outcome of overdose of heroin by ethanol. There is evidence that systemic disease may be more preva- lent in users at greatest risk of overdose. It is suggested that pulmonary and hepatic dys- function resulting from such disease may increase susceptibility to both fatal and nonfatal overdose (97). In one study, at all ranges of free-morphine concentrations, there was a greater percentage of heroin deaths when ethanol was present (98). Toxicological evi- dence of infrequent heroin use was more common in decedents with blood ethanol con- centration greater than 1 µg/mL than in those with lower concentrations (99).

Belladonna or its alkaloid in frequent doses is the most directly indicated remedy discount chloroquine 250 mg without a prescription medicine dictionary prescription drugs. In the milder forms of insanity or other forms of mental disease generic chloroquine 250 mg without a prescription treatment 32, the Homeopathist prescribes belladonna where there is violent delirium buy chloroquine 250 mg free shipping holistic medicine, with livid face discount chloroquine 250 mg visa symptoms xanax overdose, dilated pupils, protruding eyes, fury, striking or biting, spitting, inclination to throw off the clothing or tear them, intolerance of light, extreme arterial tension; but he gives in high dilutions. One physician says that in certain forms of obesity, with plethora and an inclination for general stasis, belladonna will assist in reducing the amount of fat. It acts most promptly if the tissues are smooth, dark, and deep-red, with Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 64 sluggish circulation and burning, the inflammation being confined to the structure of the integument, and not in the areolar tissues, there being no pustulation or vesicles present. It quickly determines the eruption to the skin, and retrocession is almost impossible if it is used early. If retrocession has occurred, belladonna is the most prompt remedy known for restoration of the eruption. It promotes exfoliation and assists in the general elimination of the products of the disease. It is directly opposed to the renal hyperemia or the nephritis so common as a result of scarlet-fever and diphtheria, and is our most reliable remedy with which to overcome this condition when it occurs. For the nephritis, a drop of the tincture may be given to a child ten years of age every two hours, alternated every hour with 1-2 grain of santonin. If there be a large quantity of albumin present, two grains of gallic acid every two hours will facilitate a cure. The writer has administered the remedy to the other exposed children when a single case has appeared in a large family, none of whom had an attack. It must be given in small doses: ten drops of the tincture of belladonna in four ounces of water, a teaspoonful every two or three hours to a child of six years. Some of our writers have claimed that belladonna is just as effective in preventing the development of diphtheria and measles as it is in preventing scarlet fever. They think they have excellent reasons for this conclusion, and I am inclined to believe with them. It is an excellent plan to give it with ammonium chloride in stubborn chronic cases. In prostrating night sweats, with enfeebled circulation and cool relaxed skin, belladonna or atropine is advised. In headache from fulness of the circulation of the brain dull frontal Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 65 headache, with indisposition, malaise, and cool skin, with mental torpor and a tendency to unpleasant dreams, this remedy is of value; 1 to 2 drop every hour or two. The influence of this drug as an antispasmodic against involuntary muscular action gives it some value in spasmodic colic and obstinate constipation. It is in common use in laxative pills, to facilitate the action of the purgatives. Belladonna in physiological doses is an excellent remedy for the treatment of the conditions present during the passing of biliary calculi. It very materially facilitates the passage of the stone, prevents chronic change occurring in the structure of the duct, relaxes the duct by a paralyzing effect upon the circular muscular fibers, and renders subsequent attacks less frequent and less severe. Albuminuria is the result of greatly increased renal blood pressure and capillary engorge. In subacute or chronic cases, its use must be persisted in, but the results are equally satisfactory where structural change has not taken place in too great a degree. In incontinence of urine, where there is a plethoric tendency, a stagnant capillary circulation or the tissues are relaxed, belladonna is a prompt remedy. There is an extreme form of this difficulty, in which the patient becomes very cold; the skin is cold and clammy, the pain is extreme, the hands and feet are icy cold, and the temperature subnormal. The patient can be put into a hot bath, with only good results if this is not overdone, but the equalization of the circulation can be accomplished well with belladonna. By stimulating the capillary circulation in the ovaries this agent is directly useful in the milder forms of congestive dymnenorrhea. The direct indications for the agent are nearly always present in the cool Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 66 skin, cool extremities, dulness, chilliness, and inactivity. Its influence in stimulating the capillary circulation of the ovaries in stasis renders it of value in the treatment of sterility from inactivity of those organs. If there are hysterical manifestations at the menstrual epoch, with deficient menstruation, pulsatilla may be used in conjunction with it. The agent will retard the secretion of milk in the lacteal glands, and is of service when, from the death of the child or from acute inflammation, as in severe mastitis, where abscess is threatened , or from other causes, it is necessary to suppress the secretion. Externally, belladonna is used in spinal tenderness, with congestion, also in congestive occipital headaches and lumbago. It is applied in all conditions inducing a lame back and in neuralgia of the spinal and sacral nerves. In violent acute inflammation, it acts as a sedative and anodyne while it exercises its healing properties. It is used in rheumatism, in sprained and painful joints, and in boils and carbuncles. In this form, it is of value in spasmodic urethral stricture and in painful congestive conditions of the rectum. In the treatment of phlebitis, for which we have very few specific remedies, the late Professor Clark, because of its power in overcoming hyperemia of the venous capillaries and venous walls, claimed that belladonna, in the form of a strong ointment made from the concentrated extract and kept hot, would produce very prompt results. He would watch for the physiological effect—the dryness of the mouth, dilatation of the pupils, and dry throat; he would then remove it for a while, subsequently to reapply it in the same manner. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 67 Atropine. Description—It occurs as a white crystalline body, usually in minute acicular crystals, or as an amphorous white powder of a bitter, acrid, nauseous taste and odorless. It is soluble in 130 parts of water and three parts of alcohol, fifty parts of glycerine and quite freely in ether and chloroform. Description—This salt is perhaps more commonly used in medicine than the unsaturated alkaloid, atropine. It is freely soluble in water and in alcohol, nearly insoluble in ether and chloroform. These alkaloids are of much advantage in narcotic poisoning and as stimulants in the recovery of patients from shock. The 1/100 of a grain will produce the physiological symptoms in a healthy patient. Atropine is used to dilate the pupil in examination of the interior of the eye, and it is useful in acute inflammation of that organ. It empties the capillaries of an excess of blood, abating the inflammatory processes. It prevents adhesions in iritis, and assists in breaking up any that may have occurred. Two grains of atropine are dissolved in an ounce of distilled water, or better yet, in an ounce of castor oil deprived of its ricinic acid.
