In contrast buy cheap geriforte syrup 100caps, cycle-nonspecific agents (alkylating agents) are cytotoxic during all phases of cell replication (Caliguri and Mayer proven geriforte syrup 100caps, 1989). These agents act by transferring alkyl groups to such biological substrates as nucleic acids and proteins. Summary of 16 different reports of 22 infants born to busulfan- exposed patients found two infants with major congenital anomalies (2/22, 9. Subsequent reports of two exposed pregnancies resulted in normal neonates (Norhaya et al. They also reported that six (14 per- cent) of 44 infants born to women who received an alkylating agent (30 different reports) had major congenital anomalies. Experimental animal studies also report an increased frequency of congenital anomalies with exposure to busulfan during gestation. This drug is also used to treat cancers of the bladder, cervix, colorectum, endometrium, Ewing’s sarcoma, head and neck, lymphomas, kidney, lung, osteosar- coma, pancreas, and trophoblastic tumors. In addition, cyclophosphamide is efficacious in combination with other agents for the treatment of Ewing’s sarcoma, lymphomas, osteosarcoma, and trophoblastic tumors. Several studies of cyclophosphamide metabo- lism in in vitro cultures with rat embryos showed that the compound must be bioacti- vated by a monofunctional liver oxygenase system in order to be teratogenic (Fantel et al. The morphologic changes found in vitro were very similar to those seen in vivo (Greenway et al. There is no doubt that this agent produces skeletal and central nervous system anom- alies in rats (Chaube et al. Available human data are minimal and include three case reports and one case series. A set of twins comprising one normal infant and one malformed twin exposed in utero was reported. The malformed twin had multiple congen- ital abnormalities and subsequently developed thyroid cancer and neuroblastoma (Zemlickis et al. In another case report, a fetus with multiple anomalies (cleft palate, absent thumbs, and multiple eye defects) was born to a mother who was treated with cyclophosphamide in the first trimester (Kirshon et al. A growth-retarded infant with bilateral absence of the big toe, cleft palate, and hypoplasia of the fifth digit was born to a mother who received cyclophosphamide throughout pregnancy (Greenberg and Tanaka, 1964). No ill effects have been reported in association with second and third trimester exposure to cyclophosphamide (Matalon et al. Ten normal infants were reported following cyclophosphamide therapy during the first trimester (Blatt et al. Alkylating agents 131 Hematologic abnormalities, such as pancytopenia, were reported in infants whose mothers were treated with cyclophosphamide and other agents during pregnancy (Pizzuto et al. The use of multiple agents seems more likely to be associated with pancytopenia in the fetus and newborn than does monotherapy. Several case reports of possible associa- tion of this agent with unilateral renal agenesis in the human have been published (Shotton and Monie, 1963; Steege and Caldwell, 1980), but no causal inference can be made. One of five fetuses exposed in the first trimester had a congenital anomaly (Doll et al. Central nervous system anomalies, postcranial skeleton, and palatal closure were increased in frequency among rodents whose mothers were given large doses of chlorambucil during pregnancy (Chaube and Murphy, 1968; Mirkes and Greenaway, 1982; Monie, 1961). Ifosfamide Ifosfamide (Ifex) is a chemotherapeutic agent, chemically related to nitrogen mustards and a synthetic analog of cyclophosphamide, which requires metabolic activation by microsomal liver enzymes to produce biologically active metabolites. Ifosfamide is particularly toxic to the urinary epithelium and must be given with mesna (Mesnex, Uromitexan). It is also used to treat acute leukemias and lung, pancreas, breast, cervix and endometrium cancers, as well as Ewing’s sarcomas, lymphomas, osteosarcoma, soft tissue sarcoma, and ovarian cancer. No epidemiologic studies have been published of congenital anomalies in fetuses whose mothers used this agent during pregnancy. To date there are two case reports of fetuses exposed in utero to ifosfamide-containing com- bination chemotherapy, of which one developed oligohydramnios (Barrenetexa et al. The manufacturer reports that embryotoxic and terato- genic effects have been observed in mice, rats, and rabbits. Two case reports of congenital anomalies after first-trimester combination chemotherapy (Garrett, 1974; Mennuti et al. Chemotherapy with mechlorethamine and other drugs that were discontinued prior to 132 Antineoplastic drugs during pregnancy conception did not increase the frequency of congenital anomalies among more than 40 infants above the 3. No birth defects were reported among the children of 12 women treated with mechlorethamine and other antineoplastic agents during pregnancy in one series (Aviles et al. Increased frequencies of congenital anomalies were found among the offspring of pregnant rodents that were given mechlorethamine in doses several times those normally used in humans (Beck et al. Somatic chromosome breaks have been observed among embryos of pregnant animals who received this agent during gestation (Soukup et al.

The wood has an even higher drug content but does not seem to be exploited medically order geriforte syrup 100caps on line. The plant grows wild and has also been cultivated on a commercial scale for the pharmaceutical industry purchase geriforte syrup 100caps mastercard. Drugs found in the plant include atropine, hyoscyamine, and sco- polamine, all of which are also found in jimson weed and European man- drake. They can reduce spasms in smooth muscles of the digestive tract, but they cause tremors or stiffness in other muscles. An experiment showed that belladonna can reduce breathing abnor- malities in infants. Some medical traditions have used belladonna for reducing sweat and other secretions and against tonsilitis, meningitis, scarlet fever, whooping cough, and epilepsy. At one time medical practitioners gave bel- ladonna to ﬁght Parkinson’s disease and drug addiction, but those treatments have been superseded by others. Belladonna preparations have modern usage against vesico-ureteral reﬂux, a condition in which urine ﬂows back toward the kidney from the bladder. Caregivers have administered belladonna to treat various pains, ranging from kidney stones to sore throat. The natural product is consid- ered effective against afﬂictions of the gallbladder and liver. Belladonna is 54 Belladonna used with uncertain results for depression, middle ear inﬂammation, and some heart complaints and for attempts to promote weight loss. At one time the plant had cosmetic uses from which it supposedly gained its Italian name meaning “beautiful lady. Many accounts today say that the cosmetic function was to make women more alluring by dilating the eyes’ pupils, but those stories do not explain how ﬂirting women would have handled the pain and near-blindness caused by artiﬁcial dilation. Erotic dreams may occur from ingestion, and reputedly belladonna is con- sidered an aphrodisiac in Morocco. Users have reported hallucinating inter- actions with landscapes and other persons, experiences so compelling that their hallucinatory nature was unapparent until the belladonna dose wore off. Dosage with the natural product belladonna is so risky that persons are routinely advised to use it only under guidance of a trained expert. For example, depending on circumstances a fatal dose can vary by a factor of 10, meaning that a given ingestion might be survivable, but on an- other occasion one tenth that amount could just as easily be fatal. Just handling the plant can pass its drugs into cuts and scrapes and even through unbroken skin. Yet despite powerful effects on humans, some nonhuman species (including birds, rabbits, pigs, and sheep) can consume the plant without injury—an example of why caution is needed in reaching conclusions from drug experiments on animals. Experiments show that the scopolamine component of belladonna reduces attention and vigilance while interfering somewhat with memory. Nonetheless, aer- ospace researchers have concluded that scopolamine is a satisfactory motion sickness medicine for active-duty crews. Belladonna can interfere with urination and bowel movements—drug ac- tions that are sometimes desirable, as in persons who have lost the ability to restrain such body functions. Unwanted belladonna effects include delayed passage of food from the stomach, overheating (aggravated by diminished perspiration), dry mouth, skin rash, glaucoma, hyperactivity, jabbering (or sometimes an opposite inability to speak), mania, anxiety, delirium, and con- vulsions. Psychedelic drug advocate Timothy Leary is reputed to have claimed he was unaware of anyone ever having a good experience with using bella- donna as a hallucinogen, and ﬁrsthand accounts do seem mostly negative. Stories say that in olden times belladonna was a component of witch’s brews; if so, such persons certainly partook of it for purposes rather different from those of modern recreational drug users. A medical journal author who ob- served several recreational belladonna sessions judged the substance to be powerful, but none of the users needed medical aid. Modern negative ac- Belladonna 55 counts often derive from hospitalized individuals, and they are not necessarily a representative sample of typical users. For example, compilers of one series of case reports noted that six of the seven patients were psychologically ab- normal before using belladonna. Another pair of case reports noted that both patients had histories of depression and drug abuse. Not enough scientiﬁc information to report about likelihood of addiction, tolerance, dependence, or withdrawal. Belladonna drugs have been given to pregnant women, however, to control excessive salivation and vomiting, without apparent injury to off- spring. Unseasonal Severe Poisoning of Two Adults by Deadly Nightshade (Atropa belladonna). This amphetamine was created in a laboratory in 1953 and is used as an appetite suppressant. Its qualities are similar to dextroamphetamine, al- though users perceive benzphetamine as the weaker of the two in various aspects and—with one notable exception—do not particularly ﬁnd benzphet- amine to be a substitute for dextroamphetamine. The exception is that some persons wanting to boost alertness use benzphetamine in order to avoid the jumpiness caused by dextroamphetamine. Experiments with rhesus monkeys show dextroamphetamine to be about 14 times stronger than benzphetamine when used as an appetite depressant; in dogs the difference is 5 times. Difference in potency also varies depending on the effect being measured (locomotion, blood pressure).
