The present study aimed to evaluate the stability of active pharmaceutical ingredients (APIs) from different pharmacological classes in a compounded oral suspending vehicle. Oral suspensions amoxicillin trihydrate (50 mg/mL), clozapine (25 indomethacin (5.0 levodopa/carbidopa (10.0/2.5 levothyroxine sodium (T4, 25 µg/mL), lomustine (4.0 and 10.0 methyldopa mg/mL) procarbazine (10.0 were formula...

O6-Methylguanine has been measured in peripheral blood leukocytes of 14 patients during one or more cycles of treatment with procarbazine (daily treatment for 10 days) and in 12 patients during one or more cycles of treatment with dacarbazine (single dose per cycle). Adduct formation at levels up to about 0.4 fmole/microgram DNA was detected in all procarbazine- and all but one dacarbazine-trea...

Elderly Hodgkin lymphoma (HL), commonly defined as occuring in patients over 60 to 65 years of age, is an uncommon disease. In population-based studies, the proportion of HL patients over age 60 years has rangedfrom 15% to 30%. However, the proportion of patients over age 60 years in clinical trials has been considerably lower, typically constituting < 5% to 10% of participants. Elderly HL pati...

The mutagenic and chemotherapeutic activities of the following monofunctional alkylating agents were compared in vivo: beta-chloroethylamine, dimethyl- and diethylaminoethyl chloride; methyl- and ethylmethanesulfonate; methyl- and ethylnitrosourea; and procarbazine. The bifunctional alkylating agent diethylamine 2,2'-dichloro-N-methyl-hydrochloride was used as reference. The alkylating activity...

BACKGROUND To improve survival of elderly patients with primary central nervous system lymphoma (PCNSL), we conducted a phase II study with high-dose methotrexate (MTX) combined with procarbazine and CCNU. To reduce neurotoxicity, whole-brain irradiation was reserved for patients not responding to chemotherapy. PATIENTS AND METHODS High-dose MTX was applied on days 1, 15, and 30, procarbazine...

We conducted a cohort-study among 518 female 5-year Hodgkin lymphoma (HL) survivors, aged 14 to 40 years (median: 25 years) at treatment (1965-1995). Multivariable Cox regression was used to quantify treatment effects on risk of premature menopause, defined as cessation of menses before age 40 years. After a median follow up of 9.4 years, 97 women had reached menopause before age 40 years. Chem...

The prognosis of CD20-positive (CD20+) diffuse large B-cell lymphoma (DLBCL) with central nervous system (CNS) recurrence is still poor. A standard treatment for CD20+ DLBCL with CNS recurrence in elderly patients has not been established mainly due to adverse effects. We previously reported the efficacy and safety of MIND-E (ranimustine, ifosfamide, procarbazine, dexamethasone, and etoposide) ...

Between 1970 and 1975, 108 patients who presented with advanced or recurrent Hodgkin's disease and were free of disease after six courses of chemotherapy with mustine, vinblastine, procarbazine, and prednisone (MVPP) were allocated at random to one of two regiments of maintenance treatment: either intermittent treatment with vinblastine and procarbazine or intermittent treatment with MVPP. Afte...

The protective effects of androgen pretreatment on the procarbazine-induced killing of spermatogonial stem cells in Wistar rats have been investigated. Using testosterone-filled Silastic implants (200 mm2) the degree of protection from four weekly doses of procarbazine (100 mg/kg) was found to be dependent upon the androgen pretreatment time interval as assessed by quantitative histology. No pr...
