I get a lot of headaches and thus I have taken many different pain releivers. All of them promise quick, effective relief from pain. This is especially the case with the liquigel format.
Advils version of this is a green gel pill that is very visably easily dissolved. I must say that I was impressed in which the speed of the two pills I took reacted to my headache. No sooner than 15 minutes after taking the recommended dosage (2 pills) did my headache disappear.
I do not know if any other brand would be as effective, but I was very impressed with Advil's quick acting pills and will definitely buy a bottle of these to have on hand if I should need them in the future. I do know that they are a little more expensive than traditional pain relievers, but I think it is wortht he extra cost to have it be so quick acting.
