Micardis

By K. Miguel. Westwood College � California.

One writer says that in wild delirium purchase micardis 40 mg with mastercard, sleep may be induced with this remedy order micardis 40 mg overnight delivery, and a restful quiet purchase micardis 80 mg. It should be given in doses of from one one-hundredth to one-thirtieth of a grain, hypodermically injected. The dose is less than the emetic dose, and yet sufficient to produce a physiological effect. It is not given until after the patient is undressed and in bed ready to go to sleep. Where it is used for its hypnotic effect alone, and the patient has not previously taken it, it might be well to beg in with a dose as small as the one one hundredth of a grain. The influence of the agent is not protracted, and in some cases it must be repeated in two or three hours. In others it produces a restfulness, which results in sleep, independent of further action of the remedy. In hysterical attacks, the agent is valuable, as it produces general quiet, and refreshing sleep. It may be used in the place of morphine and opium with those who are addicted to a habit for these drugs, and it will produce the same results. The drug is a treacherous one, and consequently dangerous, and must therefore be given with care. In very minute doses, it is given in bronchitis, where there is a deficiency of secretion, or in croup, producing relaxation and expectoration. It is given as an expectorant in cough mixtures, with good results, but its emetic influence should not be induced. One one-hundredth of a grain, repeated every two hours, will be sufficiently large dosage. It produces a Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 314 watery secretion of mucus, which is often undesirable. It should be used only with adults, as stated, as children are too susceptible to its influence. Kinnett has used it in pain from spasms of the pyloris, and others mention its influence for spasmodic pain in severe, acute stomach disorder in sthenic cases. Dice believes apomorphine given in small doses frequently repeated in the initial stage of appendicitis will prevent the development of many cases of this disease. He dissolves also a dram of sulphate magnesium in four ounces of water and gives a teaspoonful every two hours with it. Apomorphine in doses of One-thirtieth of a grain or less, frequently repeated controls some very severe cases of vomiting. In the treatment of alcoholism, this agent is given in sufficient quantity to produce mild nausea; then one-thirtieth of a grain of strychnine or other indicated stimulant is given for its influence upon the nervous system at the same time. Occurrence—An alkaloid of opium closely related to morphine, often, if not carefully prepared, containing a certain proportion of morphine. Character—White octahedral crystals, bitter, odorless, permanent, soluble in eighty parts of water and in three parts of alcohol. Physiological Action—Its influence is that of an anodyne and antispasmodic, more active as an antispasmodic than morphine and much less narcotic. It controls pain without checking secretion to as great an extent as the other alkaloids of opium. Therapy—It has a more marked influence upon pain in the abdomen and in the pelvic organs. Spasms, neuralgia and other painful conditions in these parts are well controlled by codeine. It has been given in doses of fifteen or twenty grains daily for this purpose, in some cases with permanent results. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 315 Codeine has a marked influence upon spasmodic cough. It is often given to soothe irritable conditions of the air passages and to control persistent annoying and exhausting cough. Opium is stimulant and narcotic, according to the dose and susceptibility of the patient. Infants and old people are easily poisoned by the drug, while those addicted to alcohol can take very large doses without any bad effects; and those accustomed to the drug can take a poisonous dose with impunity. In the healthy adult a moderate dose of opium stimulates all the nervous functions of the body, raises the spirits and excites intellectual action; this gives way to a condition of placidity, freedom from care, and a state of quiet enjoyment. In an hour or less, con-sciousness is lost in sleep, which may continue for eight hours or longer. On waking there is evidence of disturbance of the functions of the organism, such as nausea, vomiting, headache, constipation and diminished secretion, except that of the skin. In a dose sufficient to cause death the period of excitement is short, while the strength of the system rapidly gives way to drowsiness and apoplectic sleep. There is stertorous breathing, dusky countenance, slow pulse, nearly total insensibility, only responding slightly to violent agitation, with confusion of the mind, and an inclination to continue in a comatose state with increasing debility. After a few hours, six to twelve, according to the dose and the resisting power of the patient, the face becomes pale, the pulse from being full and strong becomes weak and thready, with cold extremities, a cool and clammy skin, a slow gasping respiration; a condition from which it is impossible to rouse the patient and death soon follows. The pulse is first slow from stimulation of the vasomotor nerve centers, and becomes rapid as these become paralyzed. The pupil is first contracted by stimulation of the oculo-motor nerves, and dilates as death approaches and these become paralyzed. With some individuals there appears to be an inherent and usually Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 316 permanent idiosyncrasy against the action of opium and morphine. These are nausea or violent vomiting, spasm of the stomach and loss of appetite, obstinate constipation or abdominal pain. In others there is nervous excitement, restlessness, headache, tremors, general distress and an increase of pain. Given under the conditions we have named as contraindications, it will often produce these phenomena; where there is an absence of idiosyncrasy, and where given under the proper conditions, the effects would be desirable. Itching of the skin, inducing an apparent miliary eruption, is one of the unpleasant effects of its use, which, like any one of the others, may be always greatly exaggerated in certain individuals. By using water as a solvent, or combining opium with ipecac or camphor, or in some cases with the bromides, these unpleasant effects can, in great measure, be overcome. It has poisoned infants while nursing, the mother either taking it as medicine or habitually. Caution—All of the effects of these agents are especially marked in infants and early childhood. The nervous system is profoundly impressed by them, and the dose, if given at all to very young babes, should be infinitesimal.

The coca bush is native to the Andes micardis 40 mg with visa, where it has been harvested since ancient Inca days order 40 mg micardis. Use in that era has been confirmed through analysis of hair from ancient corpses and from examination of artwork proven 20mg micardis. At first only upper-class Incas and select individuals were permitted to use coca, but usage spread to Inca society as a whole after the Spanish conquest. In modern times the plant has been cultivated in India and Sri Lanka as well as Formosa, Indonesia, and Malaysia. Its leaves are the natural product from which cocaine is refined, and blood measurements confirm that coca users receive cocaine from the leaves. Cocaine is not the only drug component of coca, but relatively little explora- tion has been made of other components. Some investigators suspect that these other drugs are more important than cocaine in producing coca’s effects. Traditionally coca has enjoyed wide use and social acceptance in the Andes, although leaf chewing (as opposed to taking coca in tea) is associated with lower social classes. Persons from middle and higher social classes who do not engage in physical labor may use coca recreationally. Usage is much more common among persons living at high altitudes than at sea level. Coca can be a social lubricant, much in the way that khat is traditionally utilized. As with wine, coca leaves produced in different regions under different condi- tions can have flavor characteristics making some varieties more sought after than others even if the drug content is virtually identical. Veins are stripped from the leaves, which typically are then chewed or sucked upon in a small 92 Coca quantity for hours, much like chewing gum. Lime (the mineral, not the fruit) may be added to improve the body’s absorption of cocaine from the leaves. Coca tea or the leaves themselves are used to aid digestion, reduce gastrointestinal colic, fight asthma, soothe vocal cords (laryngitis), relieve stress and elevate mood, alleviate cold and thirst, produce sweat, and fight motion sickness. Proposals have been made to produce coca lozenges and chewing gum to make the natural product available in formats more familiar to persons coming from a European heritage. Habitual coca chewing interferes with the body’s insulin and thereby tends to raise blood sugar levels. That finding should interest diabetic chewers but is also relevant to persons using leaves at high altitudes (common in the An- des) because the reduced oxygen supply at upper elevations tends to lower blood sugar. Blood sugar tends to decline during exercise; coca can prevent that decline, and scientists suspect that coca can increase the body’s effective use of blood sugar during exercise. Coca leaves improve a person’s access to stored energy sources in the hu- man body and thereby increase capacity for physical labor. During the nine- teenth century such qualities attracted notice in Europe, but suggestions that coca be used in industrial and military labor were apparently ignored. In the 1970s a sample of Argentine miners showed that 65% chewed coca leaves every day, and another 14% used leaves less often. The more physical power and endurance required for a particular job, the more likely that a miner used coca leaves each day. One study of coca found the typical stimulant actions of raising pulse rate and blood pressure but also found that coca had a more unusual effect of decreasing the volume of blood plasma—a condition nor- mally associated with bleeding or with not drinking enough fluids. This con- dition interferes with proper blood circulation during physical exercise, but centuries of experience suggest that coca-chewing laborers get along well enough nonetheless. The study just referred to involved habitual chewers of coca; occasional chewers may not experience the same results. For example, in another study scientists concluded that regular chewers had more access to energy stored in body fat but that occasional chewers did not and also con- cluded that occasional chewers would not show the same improved endurance during physical exercise that is demonstrated by habitual chewers. One in- vestigator has concluded that coca improves endurance but does not otherwise help physical labor (a person cannot lift more or run faster). Like many stimulants, coca reduces feelings of hunger and can thereby re- duce food intake. The appetite suppressant effect is slight, however, simply helping a person to get by more comfortably when food is scarce. Coca chew- ers exhibit robust appetites when victuals are plentiful, and coca preparations can even be an element of meal-taking. Some research suggests that under low atmospheric pressure coca can improve the body’s metabolism of carbo- hydrates and thereby improve nutrition of users. Coca itself is a good source Coca 93 of vitamins, iron, and phosphorus; and lime used with coca can provide al- most a gram of calcium per day—important supplements where diet is often deficient in such factors. Malnourishment exhibited by rural coca chewers seems related more to poor food supply than to use of coca. Rat experiments, however, indicate that coca slows growth rate if used in mountainous alti- tudes. Although individuals have to work hard to abuse coca enough to create problems, persons who succeed at that task can experience the kinds of hallucinations and other mental afflictions associated with stimulant abuse. Contrary to what one would expect from a stimulant, scientific tests show that coca (like khat) retards reaction time and increases errors in work performance. Long-term mental effects of habitual coca usage decrease think- ing abilities in ways that are seldom noticeable in rural village life but that are clearly documented through scientific tests. Such decline would put per- sons at a disadvantage in coping with modern urban conditions, on or off the job. Coca depresses the immune system, presumably making users more sus- ceptible to disease. Coca chewing is suspected of promoting spread of cholera, not from coca itself but from lime or other alkali substances chewed with the leaves, having the result of lowering the stomach’s acid content and thereby providing an excellent environment for growth of microscopic cholera organ- isms. Archeologists examining an- cient human remains have concluded that coca chewing may cause tooth decay and loss. In contrast, modern-day chewers claim that the habit promotes dental health and makes users less susceptible to disease in general. Differing backgrounds of users and abstainers hinder efforts to measure effects; factors other than coca may be affecting health. Tolerance to the drug effect (resulting in a need to keep increasing the dose) is not observed among coca chewers; lack of that classic indication of addiction is evidence of coca’s low addictive potential. Heavy coca users may exhibit mild signs of physical dependence with the drug if they stop using it, but any such transitory illness is too slight to be a factor in choosing to continue using the drug. Mouths of habitual chewers show tissue abnormalities but no pre- cancerous conditions. In the 1970s a lift of all legal controls over coca was proposed on the theory that the natural product was far less harmful than pharmaceutical stimulants and might be just as attractive to persons who were damaging themselves through stimulant abuse. Cocaine and ecgonine can be removed from coca leaves, and such “deco- cainized” leaves are legal to possess without a prescription.

Among 614 infants born to women who used estrogenic compounds during gestation discount micardis 40mg without prescription, an increase in certain congenital anomalies was found – cardiovascular discount micardis 40mg with mastercard, eye and ear defects quality micardis 20 mg, and Down’s syndrome (Heinonen et al. However, this association was reevaluated in another report, and the link between estrogens and cardiac malformations was not borne out (Wiseman and Dodds- Smith, 1984). The malignancy was diagnosed among females 7–30 years old, with a median age of 19 years. Nonmalignant abnormalities, especially adenosis, are common among the daughters of pregnant women who were treated with diethylstilbestrol. Gross structural abnormal- ities of the cervix or vagina are identified in about one quarter and abnormalities of the vaginal epithelium in one-third to one-half of women whose mothers took diethylstilbe- strol during gestation (Bibbo, 1979; Herbst et al. T-shaped uterus, constricting bands of the uterine cavity, uterine hypoplasia or paraovarian cysts also occur with increased frequency among females exposed in utero (Kaufman et al. Preterm delivery, spontaneous abortions, and ectopic pregnancy occurred with increased frequency in females whose mothers took diethylstilbestrol during gestation (Barnes et al. Progesterone is the only natural progestin and is not well absorbed by the oral route unless given in micronized form. Synthetic progestins structurally related to proges- terone are more commonly used. Low-dose progestins are used for contraception with an estrogen, and are used in the therapy of menstrual disorders at higher doses. In the 1960s and 1970s much higher doses of progesterones were used for oral contraception (Schardein, 1985), and are currently used to treat threatened abortion. In a review, female pseudohermaphroditism, including various degrees of clitoral hypertrophy with or without labioscrotal fusion, was reported in several-hundred children born to women treated with progesterone analogs in high doses during early pregnancy (Schardein, 1980, 1985). Fewer than 100 cases of male pseudohermaphroditism have been reported, and the anomaly is usually isolated hypospadias (Aarskog, 1979; Mau, 1981; Schardein, 1985). Exposure to progestational agents during embryogenesis, therefore, seems not to increase substantially the risk for nongenital congenital anomalies in infants born to treated women. Among more than 100 94 Endocrine disorders, contraception, and hormone therapy during pregnancy infants born to women who took norethindrone during the first trimester, congenital anomalies were not increased in frequency, or in more than 100 infants whose mothers took this drug after the first trimester (Heinonen et al. Two case–control stud- ies of 365 infants with congenital anomalies yielded similar results (Kullander and Kallen, 1976; Spira et al. Several cases were reported in which use of norethin- drone during pregnancy, at doses that were much greater than those used in contempo- rary practice, was associated with masculinization of the external female genitalia (cli- toral hypertrophy with or without labioscrotal fusion), but internal genitalia and subse- quent pubertal development were normal (Schardein, 1980, 1985). The genital anom- alies observed include various degrees of masculinization (Wilkins et al. Clitoral hypertrophy may occur in exposures any time after the 8th embryonic week, but labio- scrotal fusion is limited to exposure during the 8th to 13th embryonic weeks. The risk for pseudohermaphroditism among female infants born to women who took norethin- drone during pregnancy is probably less than 1 percent (Bongiovanni and McPadden, 1960; Ishizuka et al. No increased risk of fetal sexual malformation was reported in a meta-analysis of published reports of women exposed to sex hormones after conception (Ramin-Wilms et al. Masculinized external female genitalia were observed in several species of experimental animals, including nonhuman primates, following maternal treatment with high doses of norethindrone during pregnancy (Hendrickx et al. Nongenital malformations were not increased in frequency among three species of nonhuman primates given up to 100 times the oral contraceptive dose of norethindrone during pregnancy in combination with ethinyl estradiol (Hendrickx et al. Contemporary low-dose therapy with norethindrone is not a risk factor for genital mal- formations, and probably poses no increased risk for congenital anomalies in general. Congenital anomalies were not increased in frequency among more than 150 infants born to women who took norethynodrel during the first trimester, or among more than 150 women who took the drug after the first trimester (Heinonen et al. Virilization of female fetuses has not been reported in the human; however, female rat fetuses born to mothers that received several-hundred times the human contraceptive dose had masculinized external genitalia (Kawashima et al. Treatment of human pregnancy within the low-dose range presently employed for contraception and for menstrual irregularity will not cause female virilization. There are no controlled studies of congenital anom- alies among infants born to women who used norgestrel during pregnancy. Although no human reports have associated the use of norgestrel during pregnancy with masculiniza- tion of external female genitalia, large doses administered in the latter two-thirds of pregnancy would be expected to produce virilization based upon clinical experience with other closely related compounds. The frequency of congenital anomalies was not General hormonal therapy 95 increased among mouse and rabbit litters born to females treated with very large doses of norgestrel during pregnancy (Heinecke and Kohler, 1983; Klaus, 1983). Major congen- ital anomalies were not increased in frequency among almost 500 infants born to women treated with medroxyprogesterone during the first trimester, or among 217 infants whose mothers took the drug after the first trimester of pregnancy (Heinonen et al. Claimed associations between maternal use of high-dose progestins early in pregnancy and masculinization of the genitalia in female children, feminization of the genitalia in male children, a variety of malformations of other organ systems and certain behavioral alterations (Hines, 1982; Schardein, 1980, 1985; Wilson and Brent, 1981) are appar- ently not true. A large study that included 1274 cases where medroxyprogesterone was taken for first-trimester bleeding failed to reveal an increased rate of malformations when compared to 1146 control infants (Katz et al. Although ambiguous external genitalia occurred among both sons and daughters of women who were treated with high doses of medroxyprogesterone to prevent miscar- riage during pregnancy, these abnormalities were isolated and very rare (Schardein, 1985; Yovich et al. Growth, sexual maturation, and sexually dimorphic behav- ior were unaltered among 74 teenage boys and 98 teenage girls whose mothers had taken medroxyprogesterone during pregnancy (Jaffe et al. Animal teratol- ogy studies in rats, rabbits, and monkeys demonstrated that nongenital anomalies were not increased in frequency, and genital ambiguity occurred only at very high doses of medroxyprogesterone during pregnancy (Andrew and Staples, 1977; Eibs et al. The risk for virilization of female fetuses appears minimal with maternal use of large doses of this agent during pregnancy. No studies of congenital anomalies among infants whose mothers were treated with megestrol during pregnancy have been published. External genitalia of female rats born to mothers treated with very large doses of megestrol during pregnancy were virilized (Kawashima et al. Androgens Androgen use during pregnancy is strictly contraindicated, primarily due to the risk of masculinization of a female fetus. Inadvertent use during early pregnancy results in virilization of 96 Endocrine disorders, contraception, and hormone therapy during pregnancy female infants (Duck and Katayama, 1981; Kingsbury, 1985; Peress et al. A review of fetal exposure to danazol in 129 cases compiled from case reports revealed miscarriages in 12 cases and 23 elective abortions. There were 57 female fetuses whose mothers took dana- zol during the period of sensitivity to androgenic substances (8th week of embryogene- sis and thereafter), and 23 (40 percent) presented with virilization (clitoromegaly, par- tial fusion of labia majora) (Brunskill, 1992). The lowest daily dose that resulted in vir- ilization was 200 mg (Brunskill, 1992). Androgen influences on development of internal genitalia were present in only two cases (Quagliarello and Greco, 1985; Rosa, 1984). Therefore, the available data strongly indicate that virilization of the female fetus is a risk when there is exposure to danazol during the period of androgen receptor sensitiv- ity (beginning at the 8th week of embryogenesis and continuing through the fetal period). Virilization was not found among any infants exposed before the 8th week of embryogenesis (Rosa, 1984). A patient who becomes pregnant while taking the medication may not be diagnosed until a considerable fetal exposure has occurred because the drug is expected to cause amenorrhea. Therefore, physicians should be aware of the risk of female genital ambiguity occurring in the off- spring of women who are prescribed this drug. More than a dozen female infants were born to women treated with methyltestosterone during pregnancy, and they all had varying degrees of virilization of the external genitalia (clitoral enlargement and labioscrotal fusion) (Grumbach and Ducharme, 1960; Schardein, 1985).
