Abstract
This article includes a thorough examination of the inhibitory potential of quinoline-based drugs on cancer cells, as well as an explanation of their modes of action. Quinoline derivatives, due to their various chemical structures and biological activity, have emerged as interesting candidates in the search for new anticancer drugs. The review paper delves into the numerous effects of quinoline-based chemicals in cancer progression, including apoptosis induction, cell cycle modification, and interference with tumor-growth signaling pathways. Mechanistic insights on quinoline derivative interactions with biological targets enlightens their therapeutic potential. However, obstacles such as poor bioavailability, possible off-target effects, and resistance mechanisms make it difficult to get these molecules from benchside to bedside. Addressing these difficulties might be critical for realizing the full therapeutic potential of quinoline-based drugs in cancer treatment.

Abstract
An open-label, nonrandomized study was conducted to assess the effect of ravuconazole on the pharmacokinetics of concomitantly administered nelfinavir. Healthy volunteers received 750 mg nelfinavir on day 1, 750 mg nelfinavir and 400 mg ravuconazole on day 2, 400 mg ravuconazole on days 3 to 28, and 750 mg nelfinavir and 400 mg ravuconazole on day 29. The geometric means of C(max) and area under the curve of nelfinavir coadministered with ravuconazole were 30.7% and 31.9% higher on day 2 and 7.9% and 16.2% lower on day 29, respectively, compared to the corresponding values on day 1. These findings are consistent with the potential for ravuconazole to both inhibit and induce CYP3A isozymes. The alterations in the systemic exposure to nelfinavir were within the range defined by the 90% confidence interval. The study data indicate that coadministration of ravuconazole did not result in a clinically significant change in the plasma levels of nelfinavir.

Abstract
The initial formulation of the HIV protease inhibitor (PI) saquinavir (SQV) in hard gel capsules (Invirase) demonstrated significant clinical benefit in double and triple combination regimens in comparative studies. However, pharmacological limitations of this preparation resulted in fewer patients achieving optimal treatment responses than observed with other PIs. Changes in formulation and dosing to a new soft gelatin capsule formulation of SQV (SQV-SGC, Fortovase result in an average 8-fold increase in SQV exposure with SQV-SGC. Data from clinical trials indicate that this enhanced plasma exposure translates into more potent antiviral activity, with small comparative studies suggesting activity to be similar to other available PIs in triple therapy highly-active antiretroviral therapy (HAART) regimens. Additionally, SQV-SGC appears to be an excellent candidate for PI combination use. SQV-SGC appears well-tolerated with a low incidence of mainly gastrointestinal side-effects. The lower affinity to P450 isozymes of SQV means that the incidence of drug interactions is low, indeed probably lower than with other approved members of this class. Current obstacles to SQV-SGC's widespread use include only limited, short-term bid dosing data (outside of combination with ritonavir) and the pill burden of 18 capsules per day.

Abstract
PURPOSE This retrospective study investigates the effect of prior nucleoside (nucleoside reverse transcriptase inhibitor [NRTI]) experience on 2-year virologic response to an initial protease inhibitor-highly active antiretroviral therapy (PI-HAART) regimen. METHOD 152 patients who started a PI (excluding saquinavir hard gel capsule [hgc] as a sole PI) with two NRTIs between January 1996 and May 1998 at two HIV treatment sites were included. RESULTS 109 patients (71%) were NRTI experienced. 106 patients received two new NRTIs, and 32 received one new NRTI. Overall, 51% of patients had a virologic response (HIV viral load <400 copies/mL); the mean follow-up was 28 months. Virologic response was associated with the use of at least one new NRTI (relative risk [RR] 2.1; p =.031) but not with prior NRTI experience (p =.19). A complete virologic response was most likely to occur when two new NRTIs were used (RR 2.3) rather than one new NRTI (RR 1.8), but this was not significant (p =.12). CONCLUSION This study suggests that prior nucleoside experience is not a key predictor of 2-year virologic response in patients who receive at least one new NRTI in an initial PI-HAART regimen.

Abstract
PURPOSE To determine virological and immunological response to highly active antiretroviral therapy (HAART) and to investigate factors influencing response in a community-based setting. METHOD Plasma HIV RNA levels and CD4 cell counts were studied in 168 unselected individuals starting HAART including indinavir or ritonavir or hard-gel saquinavir-containing regimens. RESULTS Overall, 60% of the patients reduced their HIV RNA to below 500 Eq/mL, but half of them experienced a subsequent virologic rebound. Patients with higher baseline HIV RNA, higher baseline CD4 cell count, and simultaneous initiation of combination therapy and patients on indinavir or ritonavir regimen were more likely to have virologic response within 6 months since HAART initiation. Patients with lower baseline CD4 cell count and with lower rates of viral clearance had a higher probability of a subsequent virologic rebound. Forty percent of the patients had increased their CD4 cell counts by more than 100 cells/microL (immunologic response). The probability of immunologic response was independent of baseline HIV RNA levels and CD4 cell count; however, the more complete the virologic suppression, the higher the probability of immunologic response. Thirty percent of the patients had discordance between virologic and immunologic responses. CONCLUSION The rate of virologic failure in this unselected group of patients was higher than that observed in randomized clinical trials, but only a minority (11%) of the patients were treatment naïve. Starting combination therapy simultaneously and initiating antiretroviral therapy before advanced HIV disease has developed predict virologic response, whereas the magnitude of viral suppression predicts mid to long immunological response.

Abstract
AIMS To investigate the pharmacokinetic profile of the protease inhibitor saquinavir (SQV) after multiple doses in HIV-positive patients and to evaluate the possibility of predicting total body exposure of SQV from concentrations determined at single time points. METHODS Twenty HIV-positive patients on steady-state treatment with SQV (Hard-Gel-Capsule, Invirase(R)) were enrolled in this study. Serial blood samples were obtained during a dosing interval. SQV plasma concentrations were determined by high performance liquid chromatography (h.p.l.c.) and pharmacokinetic parameters were determined by noncompartmental techniques. RESULTS There was a marked interindividual variability in SQV pharmacokinetic parameters with a 11-fold variability in total systemic exposure to SQV, as expressed by AUC(0,8h) values (range: 268-3009 ng ml-1 h, CV: 69%). The oral clearance shows an interindividual CV of 75%. A strong correlation (r=0.94) was found between SQV plasma concentration at 3 h (C3 h ) and AUC(0,8h). CONCLUSIONS This study shows that C3 h is a good predictor for total body exposure of SQV and might be useful to predict SQV disposition in HIV-positive patients on steady-state treatment.

Abstract
OBJECTIVE New antiretroviral strategies aim to reduce plasma HIV RNA (viral load) to below the limits of detectability of assays with the objective of reducing viral replication in order to stop or reverse the pathogenic process and prevent development of drug resistance. First use of a protease inhibitor might offer the most realistic chance of achieving this aim. Our objective was to study the virological response to protease inhibitors in patients taking them for the first time. METHODS A total of 901 patients from a large outpatient clinic were followed a mean of 15 months from the time of starting a protease inhibitor until 1 May 1998. Viral load and CD4 cell count measurements were made on average every 34 days. RESULTS Overall there was a 79% [95% confidence interval (CI), 76-82] probability of the patients achieving a viral load < 500 copies/ml by 24 weeks after starting the protease inhibitor. In a multiple Cox regression model, those with lower initial viral load [relative hazard (RH), 0.72; P < 0.0001], higher CD4 cell count (RH, 1.07; P = 0.002), those starting other new drugs at same time as the protease inhibitor (RH, 1.46 for two versus none; P = 0.003), those who were antiretroviral-naive, and those using indinavir or nelfinavir were more likely to achieve such levels. In those 651 patients achieving viral load < 500 copies/ml within 24 weeks, there was an estimated 53% (95% CI, 51-55) probability of rebound of viral load to > 500 copies/ml by 52 weeks from the first undetectable value. Again, those who had started other new drugs at the same time as the protease inhibitor (RH, 0.57; P = 0.003 for starting two versus none) tended to experience a lower probability of viral load rebound, as did those with higher initial CD4 cell count (RH, 0.87 per 100 x 10(6)/l higher; P = 0.0007). Those who took saquinavir achieved less durable virological responses than those who took other protease inhibitors. CONCLUSIONS Starting protease inhibitor therapy with two other new antiretroviral drugs simultaneously with protease inhibitor therapy offers a better best chance of achieving sustained viral load < 500 copies/ml than starting fewer new drugs.

Abstract
OBJECTIVES To investigate the factors related to viral load becoming undetectable among patients from Southern Alberta who started a protease inhibitor for the first time, and to determine the factors related to subsequent re-emergence of detectable viral load amongst those patients whose viral load initially became undetectable. SUBJECTS AND METHODS A total of 243 patients from the Southern Alberta Clinic had started a protease inhibitor for the first time and had been followed up for a median time of 32 weeks. Standard survival techniques including Kaplan-Meier techniques and Cox proportional hazards models were used to determine which factors were related to viral load becoming undetectable. RESULTS At 24 weeks after first exposure to a protease inhibitor, 52.8% of the patients [95% confidence interval (Cl), 45.2-56.6] had achieved an undetectable viral load. In a multivariate analysis, those with a higher initial viral load were less likely to become undetectable [relative hazard (RH), 0.50; 95% Cl, 0.35-0.70; P < 0.0001], whereas those starting more new drugs (RH per new drug, 1.54; 95% Cl, 1.01-2.11; P = 0.048) were significantly more likely to achieve an undetectable viral load. Amongst 111 patients whose viral load became undetectable, Kaplan-Meier analysis indicated that 15.5% of patients experienced re-emergence of detectable viral load at 24 weeks after the first undetectable viral load. A higher CD4 cell count was associated with a lower risk of viral load becoming detectable (RH, 0.73; 95% Cl, 0.53-1.00; P = 0.049), as was treatment with indinavir (versus any other protease inhibitor RH, 0.17; 95% Cl, 0.03-0.86; P = 0.033). CONCLUSIONS A significant proportion of patients in a routine clinic setting achieved an undetectable viral load measurement after first starting a protease inhibitor; viral load in patients with a higher CD4 cell count was more likely to become and stay undetectable. There was no evidence that patients who were drug-naive experienced significantly worse virological effects than drug-experienced patients, as long as the same number of new drugs was started at the date of first exposure to a protease inhibitor. Further follow-up of these patients is warranted to study the longer term effects of treatment with protease inhibitors.

Abstract
OBJECTIVE To review and update the incidence, mechanism, and clinical relevance of drug interactions with itraconazole, ketoconazole, and fluconazole. DATA SOURCES Literature was identified by MEDLINE search (from January 1990 to May 1997) using the name of each antifungal and the term "interaction" as MeSH headings. Abstracts were identified by literature citation and by review of Interscience Conference on Antimicrobial Agents and Chemotherapy from 1995 to 1996. STUDY SELECTION Randomized, controlled, double-blind studies were emphasized; however, uncontrolled studies and case reports were also included. In vitro data were selected from literature review and citations. DATA EXTRACTION Data were evaluated with respect to study design, clinical relevance, magnitude of interaction, and recommendations provided. DATA SYNTHESIS The incidence of fungal infections and consequent azole antifungal usage continues to increase. By virtue of their antifungal mechanism (i.e., inhibition of cytochrome P450 fungal enzyme systems), azoles have been investigated and implicated in several drug interactions. The magnitude of interactions can vary from trivial to potentially fatal, and also vary with specific azole and interactant. CONCLUSIONS The azole antifungal agents represent a commonly used class of agents with a broad range of potential interactions. Recent data have increased our understanding of drug--drug interactions with azoles. Pharmacists are in a unique position to identify these interactions and to intervene to decrease their morbidity and improve patient care.

Abstract
The haemophilias are a group of inherited haemostatic disorders that require regular clotting factor replacement therapy in the severe and moderately severe subgroups. Prior to the introduction of adequate viral inactivation methods in 1985, haemophilia patients were at exceptionally high risk of contracting blood-borne viruses from factor concentrates as each batch was derived from the plasma of thousands of donors. As a result, approximately 60% of these patients were infected with HIV between 1979 and 1985, and HIV infection now contributes significantly to the morbidity and mortality seen in this group. Protease inhibitors (PIs) have been shown to significantly log reduce viral loads and increase CD4 cell counts in HIV-infected individuals. Recently, there has been concern about their use in HIV-infected haemophilia patients following increased bleeding episodes in some patients during PI therapy. We prospectively studied the effect of PI therapy in 20 HIV-infected haemophilia patients at our centre over a 6-month period. The mean increase in CD4 cell count was 70 x 10(6)/l and the mean log decrease in viral load was 1.59 over the study period. Gastrointestinal side-effects (nausea and vomiting in five, diarrhoea in two) were the most frequent and resulted in discontinuation of the medication in two patients. Factor concentrate usage for the group on and off study was similar. One severe FVIII patient reported a single episode of an unusual bleed which responded promptly to FVIII concentrate infusion. The significant clinical and laboratory benefits in terms of HIV disease and the paucity of added bleeding complications suggest that PI therapy should not be withheld from HIV-infected haemophilics. Further prospective studies evaluating the efficacy and possible haemostatic complications related to these promising inhibitors of the HIV protease are needed.

Abstract
OBJECTIVE To investigate the pharmacokinetics of saquinavir (SQV) hard gel when administered alone and in combination with nelfinavir (NLF) to HIV-positive patients. DESIGN Six patients receiving triple therapy (dual nucleoside plus SQV 600 mg three times daily) were studied. On the first study day blood samples were drawn for assay of SQV. Prior to the second study day, patients received their usual medication plus NLF 750 mg three times daily for 2 days. METHODS Blood samples were obtained at times 0, 1, 2, 4, 6 and 8 h after dosing on study days 1 and 2. Following centrifugation, separated plasma was heated at 58 degrees C for at least 30 min to inactivate HIV and stored at -80 degrees C until analysis using high performance liquid chromatography. RESULTS The geometric mean Cmax and AUC0-8 h on the first study day were 253 ng/ml (range, < 25-1200 ng/ml) and 1106 ng/ml.h (range, < 100-3479 ng/ml.h), respectively, and on the second study day were 1204 ng/ml (range, 379-2755 ng/ml) and 5472 ng/ml.h (range, 1434-12,538 ng/ml.h), respectively. The geometric mean ratio for Cmax was 4.75 and for AUC0-8 h was 4.94. CONCLUSIONS NLF increases the oral bioavailability of SQV (hard gel) approximately fivefold. For some patients the addition of NLF to SQV will increase the drug levels from subtherapeutic to the therapeutic range. In one of our patients the addition of NLF resulted in SQV levels that were much higher than previous work suggests are necessary for maximum antiviral effect. The variability in SQV concentrations both at baseline and following addition of NLF suggest that dosing may best be adjusted by individual therapeutic drug monitoring.
