Tiazofurin is a novel C-nucleoside with significant antitumor activity in murine tumor models. In a phase I clinical trial, patients received tiazofurin by bolus iv infusion daily for 5 days. Six doses ranging from 550 to 4100 mg/m2/day were evaluated. Thirty-one treatment courses were initiated in 21 patients. Tiazofurin induced multiple, transient toxic effects at all but the lowest dose level, and treatment interruption was a common result. Nine of 28 treatment courses initiated at doses greater than or equal to 1100 mg/m2/day were interrupted at less than 5 days; only five of eight courses initiated at 1100 mg/m2/day were completed. Symptoms leading to treatment interruption included headache, nausea and emesis, and lethargy and malaise. Other significant, transient toxic effects included skeletal muscle injury manifest as pain, weakness, or serum biochemical abnormalities; mucocutaneous effects; and mental or mood changes. One case each of transient pericarditis and fatal cardiomyopathy occurred at the highest dose. Myelosuppression was observed but was transient and not dose limiting. In addition to leukopenia and thrombocytopenia, unexpected declines in serum hemoglobin were observed, although these were of uncertain significance. Tiazofurin induced significant increases in uric acid production which could be reversed with coadministration of allopurinol. Pharmacokinetic analysis revealed tiazofurin plasma elimination to be at least biphasic, with a beta-half-time of 4.2 hours; most of an injected dose could be recovered from the urine as unaltered compound within 24 hours. From this study we conclude that an appropriate dose for phase II trials with this schedule is less than or equal to 1000 mg/m2/day. The schedule may be a difficult one for clinical evaluation of antitumor activity, however, because of the possibility of frequent treatment interruption due to multiple systemic toxic effects.

We undertook a phase 1 study of Carboplatin (CBDCA) on an intermittent single intravenous (IV) bolus (schedule A) and a 24-hour continuous infusion schedule (schedule B). Hydration and forced diuresis were not performed. Patients were not premedicated for anticipated vomiting. Thirty-eight adult patients with solid tumors received a total of 71 courses. In schedule A, doses were escalated from 20 to 600 mg/m2. The dose-limiting toxicity was myelosuppression. At doses of 270 mg/m2 and higher, leukopenia and thrombocytopenia were reproducibly seen. The dose of 600 mg/m2 was the maximally tolerated dose, producing severe thrombocytopenia (platelet counts less than 30,000/microL). Other toxicities included a fall in hemoglobin levels and tolerable nausea and vomiting. Schedule B produced comparable hematologic and emetogenic toxicities to those in schedule A. In three patients audiograms became abnormal with high-frequency hearing loss without overt deafness. Two patients developed hypomagnesemia without irreversible renal dysfunction. Patients with poor performance status, preexisting renal dysfunction, a third fluid space, or bone metastases seemed to develop increased hematologic toxicity. The recommended phase 2 dose for good risk patients is 400 mg/m2 IV bolus and for poor risk patients 270 mg/m2 IV bolus. Responses were seen in one patient each with head and neck carcinoma (partial response), small cell lung cancer (minor response), and breast cancer (minor response).

An evaluation was made of 278 healthy-appearing 1-year-old infants who were tested for iron deficiency to determine the relative frequency of adverse side effects attributable to oral iron treatment. After obtaining parental informed consent, laboratory tests of iron status were performed on venous blood and infants with hemoglobin level greater than 10.5 g/dL were randomly chosen to receive 1.2 mL of ferrous sulfate (FeSO4) drops (about 3 mg of iron per kilogram per day) or equal volume of placebo for 3 months. After 3 months of treatment, infants were to return to the clinic for repeat blood testing, compliance estimation, and evaluation for possible adverse side effects. There was no significant difference (P greater than .50) in the frequency of vomiting, diarrhea, or fussiness in iron-treated infants (6%) compared with placebo-treated infants (9%). Constipation was slightly more frequently reported (P = .03) in placebo-treated infants (9%) than in iron-treated infants (1%). Compliance with therapy was confirmed in 179 completely evaluated infants by the lack of remaining medication at 3 months, the higher incidence (P less than .0001) of dark stools reported among iron-treated infants, and the changes in laboratory tests of iron status. No parents reported dark stools as an adverse effect of therapy. It is concluded that once daily, moderate-dose FeSO4 therapy given to fasting 1-year-old infants results in no more gastrointestinal side effects than placebo therapy.

Although nausea and vomiting in early pregnancy is extremely common, very little information on the cause and course of this disorder is available in the literature. A prospective laboratory and clinical study of 102 consecutive healthy pregnant women was undertaken to evaluate nausea and vomiting in relation to clinical data, serum electrolytes, creatinine, total protein and hemoglobin. Multigravidae suffered from emesis gravidarum at a higher rate than did primigravidae. The frequency of emesis was especially high in women with short intergestational intervals. During pregnancy there was a decline in systolic blood pressure only in non-emetic women. The diastolic blood pressure in late pregnancy was significantly higher in emetic women than in non-emetic subjects. All laboratory values were within normal ranges. However, major changes occurred during pregnancy but some alterations were noted only in the emetic pregnancy. A different response to the hormonal situation is suggested to explain the dissimilarities between the emetic and non-emetic pregnancy.

424 pregnant women seeking termination of 2nd trimester pregnancy had either PGF2alpha (290 women) or PGE2 (134 women) administration. Oxytocin was concomitantly administered as an intravenous infusion to 185 women. The patients were divided into 11 groups based on PG (prostaglandin) type and dose, route of PG administration, and oxytocin infusion (Table 1). Vital signs were monitored hourly and blood samples collected from most patients for analysis of erythrocyte sedimentation rate, hemoglobin, blood leukocytes, and glutamic oxaloacetic transaminase before induction, at or immediately after abortion, and 24-48 hours after abortion. Side effects reported included diarrhea, vomiting, headache, and vasovagal symptoms. Complications included bleeding of 500 ml or more; pelvic infection and cervical rupture. Intraamniotic administration of 50 mg PGF2a either alone or with supplemental intravenous oxytocin, and intraamniotic use of 10 mg of PGE2 supplemented with oxytocin provided the best results in terms of success rate (100%) and shortest induction-abortion interval (14.1 to 16.2 hours). Extraamniotic administration had success rates ranging from 83% to 90%, depending on frequency of PG application. Intravenous PG administration was associated with low efficacy and high frequency of side effects.

264 women (about 50% private patients), all less than 40 years old and none with history contraindicating oral contraception, were started on a regimen with Ovral (.5 mg norgestrel and .05 mg ethinyl estradiol). Medication started on Day 5 of a menstrual cycle. Then therapy followed a 3 weeks on, 7 days off schedule. Patients continued for 1-22 cycles (mean 7 cycles) for a total of 1918 cycles. Despite the omission of 42 doses by 32 patients, no pregnancies occurred. The percentages of cycles with average flow, spotting, breakthrough bleeding, and dysmenorrhea were 74.4, 2.5, .4, and .6, respectively. The incidence of amenorrhea, .2%, was spectacularly low in comparison with findings in other studies. Papanicolaou smears (483) were all normal (Class I or II). Morphologic changes seen at endometrial biopsy (61) were similar to those produced by other available progestogen-estrogen compounds. No significant variation from control findings (1878) were found in 1463 laboratory studies. The studies included leukocyte and differential counts (724), and determinations of hemoglobin and hematocrit (388), fasting blood sugar and blood urea nitrogen (114), bilirubin and liver function (61), and renal function (176). Minor symptoms (nausea, vomiting, headache, etc.) were few and disappeared after the first few cycles. The preparation suppresses ovulation (probably through action of the estrogen), probably alters the cervical mucus to inhibit sperm penetration, possibly interferes with nidation, and may interfere with follicular development.

Data from 5 studies recently conducted in Bangladesh regarding dizziness as a major side effect of oral contraceptive (OC) use were reviewed. The Bangladeshi women describe dizziness as "Mata gurai" (headspinning), a sensation of rotary motion unaccompanied by nausea or vomiting. It appears to mimic the characteristics of postural hypotension rather than true vertigo and is often associated with generalized weakness. Both dizziness and weakness were cited by a large proportion of women in study A as reasons for discontinuation, and the 2 symptoms were often linked. Burning sensations, usually in the extremities, also proved to be a frequent cause of discontinuation. In study B, except for dizziness, there was no significant difference between women continuing OC use and those who had stopped use. The incidence of dizziness reported by discontinuers was significantly higher than that reported by continuing users. The case-control health survey used in study C corroborated the view that some complaints associated with OC use were equally common in nonusers, but the incidence of dizziness and eye problems was significantly higher in OC users than in both matched control groups. There were no significant associations found between dizziness and hemoglobin levels or blood pressure in study D. Of those women who took multiple vitamin capsules in study E, 57% reported a lessening of dizzinesss, compared with 69% who received glucose capsules.

A group of 71 women between 11-20 weeks of gestation who desired termination of pregnancy and had no contraindications for prostaglandin (PG) administration were given complete physical and gynecological examinations; hemoglobin was estimated and urinalysis was done. They were then given orally 2 tablets of Lomotil (diphenoxylate HCl 2.5 mg + atropine sulphate 0.025 mg) and 1 tablet of Stemetil (Prochlorperazine 5 mg). They were then given 15 (S) 15 methyl PGF2alpha intravenously at the dose level of 1 mcg/min. 61 subjects (85.9%) aborted within 30 hours. At regular intervals pulse rate, blood pressure, uterine pain, nausea, vomiting, diarrhea, temperature, and respiratory rate were measured and any other side effects were recorded. The mean induction abortion interval was 15.65 hours, the mean number of episodes of vomiting and diarrhea was 0.9 and 0.6 respectively. This study compared well with the intramuscular route of administration with a higher rate of complete abortions and lower rate of side effects. The latter is explained on the basis of smaller amounts of the drug being infused at a slower rate. Disadvantages include confinement to bed, discomfort, and need of constant supervision. Compared with intraamniotic and extraamniotic case studies, the latter are invasive procedures while the intravenous method is not. Also, the intravenous route allows for adjusted drug dosage and stopping the procedure in the event of an undesirable reaction.

Twelve patients with unresectable and recurrent non-small cell carcinoma of the lung were treated with a combination chemotherapy consisting of cis-platinum and adriamycin. The overall response rate was 42% with two complete responses and three partial responses. The durations of response were 9+ and 8.5+ months in two complete responses, and 7.5+, 5.5+ and 2.5 months in three partial responses. The overall median survival was 8 months ranging 3.5+ to 16+ months. Three patients had leukopenia less than 2,000/mm3, two patients had thrombocytopenia less than 100 X 10(3)/mm3, and four patients had hemoglobin decrease of 3 g/dl or more. Severe nausea occurred in nine patients, whereas vomiting did in seven patients. Nearly total alopecia was observed in all patients. Renal toxicity in four patients was also observed, but was reversible. We believe that the combination chemotherapy with cis-platinum and adriamycin is promising in the management of patients with non-small cell carcinoma of the lung.

Thirty four beagle dogs, male and female were orally given 10, 30, 100 and 200 mg/kg/day of captopril, an angiotensin converting enzyme inhibitor, for 3 months followed by a recovery test for 4 weeks. One of 4 female dogs which were treated with the highest dose of 200 mg/kg/day throughout the experimental period died of bronchial pneumonia. Hypersalivation and occasionally vomiting was observed in dogs treated with 100 and 200 mg/kg/day. Skin eruption such as erythema and papules was observed mostly at the ventral surface of the neck, chest and upper abdomen in dogs in these two experimental groups. Histological examination of the lesion revealed cellular infiltration with edema and expansion in the dermis and slight hyperkeratosis with parakeratosis and acanthosis. Changes in erythrocyte counts, hematocrit values and hemoglobin contents during the course of administration were variable among dogs but these were obvious in animals treated with higher doses. An increase in erythropoiesis of the bone marrow, extramedullary hematopoiesis and slight hemosiderosis in liver and spleen were revealed by histological examination. Above histological observations suggest that captopril may cause hemolysis. Hypertrophy and hyperplasia of juxtaglomerular cells with increased number of JG granules were shown in the highest dosage group even 4 weeks after suspension of captopril administration. A distinct plasma renin activity supported the morphological changes. From the results of three months administration of captopril to beagle dogs, the maximum non-toxic dose may be around 10 mg/kg/day and toxic dose 100 mg/kg/day.
