Ten-year follow-up of familial hypercholesterolemia patients after intensive cholesterol-lowering therapy.

To prevent coronary artery disease, it is necessary for patients with familial hyper-cholesterolemia (FH) to maintain a low cholesterol level. Recently a combination therapy of low-density lipoprotein (LDL) apheresis and statins has been used for FH patients, but their long-term prognosis over 10 years is unknown. In this single center prospective report, 18 FH patients with severe coronary stenosis received LDL apheresis every 2 or 4 weeks and statin therapy for 9.

Differentiation between patients with takotsubo cardiomyopathy and those with anterior acute myocardial infarction.

Background: There has not been a comparison of the electrocardiographic (ECG) finding of ST-segment elevation in the precordial leads in patients with takotsubo cardiomyopathy (TC) and those with anterior acute myocardial infarction (AMI), with regard to the location of the culprit lesion.

Methods And Results: The present study evaluated 18 patients with TC, and 85 with anterior AMI who were divided into 3 groups: group A had the culprit lesion proximal to both the first septal branch (S1) and the first diagonal branch (D1), group B had the culprit lesion proximal to either S1 or D1, and group C had the culprit lesion distal to both S1 and D1. In patients with TC, reciprocal ST-segment depression in the inferior leads was observed less frequently than in patients in groups A (p<0.

[Stability of nilvadipine solid dispersion tablet with non-packaging condition].

Nilvadipine (NIL) solid-dispersion tablets were stored counter to packaging instructions by exposing them to 40 degrees C, 25 degrees C, 75% relative humidity, and light. The dissolution, stability assay, and tablet properties (weight, thickness and hardness) were then examined. NIL dissolved more than 85% after all storage periods with exposure to high temperature and humidity.

Application of nilvadipine solid dispersion to tablet formulation and manufacturing using crospovidone and methylcellulose as dispersion carriers.

Nilvadipine (NIL) solid dispersion using crospovidone (Cross-linked-N-vinyl-2-pyrolidone, cl-PVP) and methylcellulose (MC) as carriers was applied to tablet formulation. Several grades of cl-PVP and MC were used, and their influence on tablet properties such as hardness, disintegration, dissolution and chemical stability were investigated. The agitation granulation method was used for preparation of solid dispersion granules, and the granules were compressed using a rotary tableting machine, and finally the obtained tablets were coated with film.

An attempt to stabilize nilvadipine solid dispersion by the use of ternary systems.

Firstly, we investigated the physical stability of nilvadipine (NIL)/crospovidone (cl-PVP) solid dispersion during storage (40 degrees C, 75% relative humidity) with powder x-ray diffraction, differential scanning calorimetry (DSC) and dissolution test. These studies indicated that recrystallization occurred during storage and that the dissolution of NIL greatly decreased, compared with that of the initial finding. Secondly, to improve the amorphous form physical stability of NIL, methylcellulose (MC) was added to NIL/cl-PVP solid dispersions as a dispersion carrier and NIL/cl-PVP/MC ternary solid dispersion systems were obtained by the solvent method.
