In this study, we evaluated the synergistic effect of ginger and nifedipine on anti-platelet aggregation in normal human volunteers and hypertensive patients. The results showed that the percentage of platelet aggregation induced by collagen, ADP and epinephrine in hypertensive patients was larger than that in normal volunteers. Either aspirin or ginger could potentiate the anti-platelet aggregation effect of nifedipine in normal volunteer and hypertensive patients. These results suggested that ginger and nifedipine possessed synergistic effect on anti-platelet aggregation. A combination of 1 g ginger with 10 mg nifedipine per day could be valuable for cardiovascular and cerebrovascular complication due to platelet aggregation.

U.v .-visible spectrophotometric studies of the interactions of Naproxen, Ibuprofen and Panadol with α-cyclodextrin , β-cyclodextrin, γ-cyclodextrin and dimethyl β- cyclodextrin enable the determination of stability constants of inclusion complexes when their formation gives rise to appreciable spectral changes. The magnitudes of the stability constants are discussed in terms of the relative sizes and the chemical natures of the cyclodextrins and the included molecules.
