Limestone is by definition a rock that contains at least 50% calcium carbonate in the form of calcite by weight. All limestones contain at least a few percent other materials. These can be small particles of quartz, feldspar, clay minerals, pyrite, siderite and other minerals.
Answers (4) You have not mentioned the name of the medicine in your post. Ideally 4 times a day means every 6 hours. It depends on what the medicine is as to how rigid you should be in regards to dosing. If the medicine is an antibiotic then every 6 hour dosing is important as is pain relief medication if in severe pain. If the dosing isn't so critical then 4 times a day could be evenly spaced out during the waking hours.
10mg four times a day, up to 100mg a day total. But be careful because it can cause urinary retention. 2.Neurontin, initially marketed as an antiseizure med, it's now used for nerve pain. Start at 300mg a day and titrate upwards to 3000-4000mg a day. Makes you sleepy 3.Steroids, IV or orally.
