Tablet testing regular

A 43-year-old man was admitted to hospital suffering halluoinations. He had fallen off his bike, fraotured a bone in his shoulder, and was presoribed one to two tablets of Tylenol (paracetamol plus codeine) every four to six hours for two days. He oontinued to suffer occasional hallucinations and vomiting and from jaundice. Once in hospital liver function tests on his blood indioated that he had liver damage. He died in a hepatic coma thirty hours after being admitted to hospital. It was later revealed by relatives that the patient had also treated himself with nine Tylenol tablets plus ten tablets of another preparation after the bicycle accident. Another important factor was that he regularly drank half a case (twelve bottles) of beer each day. ... 

Some foods, of course, have more cholesterol than others. Eggs, organ meats, and shrimp are particularly cholesterol-rich. For about ten years, I never ate a single egg yolk. Since discovering how well the phytosterols work, I now regularly enjoy eggs in all forms and my cholesterol tests have never been better. I just swallow a couple of tablets at the start of the meal. 

The recommended guidelines for baseline and routine laboratory testing for lithium are listed in Table 68-12. The 12-hour postdose lithium serum concentration may be 12% to 33% higher with extended-release preparations and lower with regular-release tablets with divided dosage schedules. The dose should be adjusted based on the steady-state serum concentration drawn 12 hours ( 30 minutes) after the last dose. A therapeutic trial (lithium serum concentrations of 0.6 to 1.2 mEq/L) should last a minimum of 4 to 6 weeks. Acutely manic patients may require serum concentrations of 1 to 1.2 mEq/L, and some need up to 1.5 mEq/L to achieve a therapeutic response. Although serum concentrations less than 0.6 mEq/L are associated with higher rates of relapse, some patients may do well at 0.4 to 0.7 mEq/L. For bipolar prophylaxis in elderly patients, serum concentrations of 0.4 to 0.6 mEq/L are recommended because of increased sensitivity to adverse effects. ... 

Because of the well defined shape of tablets, crushing tests are regularly and with great success used in the pharmaceutical industry in-line or off-line and often automatically, in combination with an automatic sampler, for monitoring tablet strength. Other modern, fully automated equipment measures tablet weight, thickness, diameter, and hardness for quality control and validation (Fig. 5.32).
