Flunarizine

SSHP Meeting Information 2006 Great educational meetings for SSHP members are currently in the planning stages. The SSHP Annual Spring Meeting may be in North Carolina in April 2006, with the educational focus on acute care issues. This will probably be a joint educational meeting with the North Carolina Society of Health- System Pharmacists. Lots of time for networking and fun events will be included, so stay tune for more information on this meeting. The possibility of a joint meeting with the Georgia Society of Health-System Pharmacists is also being considered for later in 2006. These meetings offer great education, fun events, refreshment breaks, and great opportunities to network with other SSHP members as well as members of a different state society. Share practical ideas with your colleagues, and take some great knowledge on drug therapy issues plus some useful ideas for pharmacy programs and interventions back to your practice setting! Meet pharmacists that you can network with regularly on various pharmacy-related issues. Build your interstate colleague network by participating in SSHP activities. Stay tune to the SSHP website at seshp for updated meeting information. Also, you are encouraged to contribute any comments, questions, or interests you may have, any recent activities you have been involved with, or other topics of membership interest just go to the "Guest Book" entry on the SSHP website. Let SSHP hear from you!

Abolished, however, by flunarizine, indicating that T-type calcium channels were involved Fig. 8 B ; . The effect of veratridine is reproduced by, but independent of, GDNF We then compared the neuroprotective activity of veratridine to that of GDNF, the prototypical neurotrophic peptide for mesencephalic DA neurons Lin et al., 1993 ; . In the presence of optimal concentrations of GDNF 10 ng ml ; veratridine 0.8 M ; , TH neurons survived to the same extent Fig. 9A ; . This suggested that the activation of voltage-gated sodium channels by veratridine might have increased DA cell survival by stimulating the production and subsequent release of GDNF into the culture medium. However, an anti-GDNF antibody AB212 NA; 5 g ml ; , which completely neutralized the trophic effect of the peptide, failed to reduce that of veratridine Fig. 9A ; . Furthermore, the effect of GDNF did not require the activation of TTX-sensitive voltage-gated sodium channels or T-type calcium channels, because neither TTX nor flunarizine reduced its survival promoting activity Fig. 9B ; . The neuroprotective effect of veratridine is not mediated by other putative secreted factors We also examined the possibility that a factor other than GDNF, secreted by glial or neuronal cells, mediated the trophic action of veratridine. Hence, we analyzed the survival of TH cells maintained in a culture medium that had been conditioned previously by mesencephalic cultures exposed to 0.8 M veratridine. After 10 d of daily treatment, this medium afforded protection to DA neurons, but only because it contained veratridine, because its effect could be abolished by either TTX or flunarizine Fig. 9C. The decay of T-type Ica not shown ; . Voltage-Dependent Block Voltage-dependent blocks were examined quantitatively by using the double-pulse protocol. The VH was set at -80 mV for L-type Ilc and at -120 mV for T-type Ich. The duration of prepulse was 3 seconds, a time sufficient to attain a steady-state inactivation of both types of 1Ca.8 The double-pulse method in the presence of each Ca 2 antagonist was carried out after the inhibition at each VH had reached a steady state by repetitive stimulations at 0.033 Hz. In the experiment shown in Figure 6, the blocking effect of nicardipine on L-type Ica increased as the prepulse potential depolarized. Figures 7A and 8A show relations between the prepulse potential and the amplitude of Ica, and Figures 7B and 8B show the steadystate inactivation curves obtained by normalizing the current evoked from a VH without inactivation as 1.0. Continuous lines were fitted by the Boltzmann equation using the least-squares method. Table 3 summarizes the effects of the Ca2' antagonists on the parameters of this equation. Nicardipine, diltiazem, and flunarizine significantly shifted the steady-state inactivation curve of L-type lCa toward the negative potential in the order of nicardipine flunarizine diltiazem, while verapamil slightly affected the.

A 20-23 g wet wt sample of cells was harvested and suspended in 44--51 ml of an extraction medium as described by Dolle & Nultsch 19886 ; . The piperazine derivative flunarizine 10~5M ; was added, which has been shown to cause immediate detachment of the flagella from the cell bodies Nultsch et al. 1986 ; . The suspension was stirred for 15 mm in ice-cold water bath and subsequently centrifuged at 4C for 30min at 1500# 4000revsmin" 1 , MSE high-speed 18 centrifuge, rotor angle head no. 69180 ; . The flagella-containing supernatant was stored at 4C and the pellet was resuspended in extraction medium once more. A second centrifugation of this suspension followed, and the resulting supernatant was combined with the first one. This flagellacontaining suspension was pelleted at 28 000 # 15 000 revs min~ , MSE high-speed 18 centrifuge, rotor angle head no. 69180 ; for 60 min and resuspended in 2-3 ml of 'assay medium' for the radioligand binding studies, consisting of 50 mM-Tris Mes pH7-5 ; , 0-33 M-sucrose, lOmM-DTT and 1 mM-PMSF. The protein yield amounted to about 0-02 % of the wet weight.

Prophylactic therapy for migraine should be considered when the frequency of migraine is high, when treatment of the acute phase is insufficient, when treatment during the acute phase is contraindicated or is impossible due to adverse reactions, or when abuse of the acute phase treatment is observed. Traditionally propranolol, a -adrenergic blocking agent, and amitriptyline, an antidepressant, were considered effective prophylactic agents and they have thus been employed. Flunarizine, an effective calcium channel blocker, was employed lately, but it has been taken off the market in Japan due to adverse reactions. Thereafter, lomerizine was developed in Japan. In a placebo-controlled doubleblind development study11 ; it was revealed that, compared with placebo, lomerizine significantly reduces the frequency and degree of headaches. Currently, it is widely utilized on the clinical scene. Flunarizine was more efficacious than nimodipine in reducing migraine frequency p 001 ; , pain severity p 05 ; , migraine index p 05 ; and corrected migraine index p 05.
