Chemically, most drugs are either weak acids or weak bases. In an acidic environment, as in the stomach, acidic drugs are unionized according to the following simple equation: where A is an acidic drug and the excess hydrogen ions drive the equation to the left. In an alkaline environment, as in the small intestine and the majority of body fluids, basic drugs are unionized according to the following simple equation: where B is a basic drug and the deficit of hydrogen ions drives the equation to the right. Thus, acidic drugs are preferentially absorbed in the stomach and basic drugs are preferentially absorbed in the intestine.

There are many drugs in the cephalosporin group. They are closely related to penicillins and have the same mechanism of action and potential for hypersensitivity reactions. Resistance to them can occur by several mechanisms.

They include the relatively mild drowsiness, dizziness and ataxia, to the more severe mental and motor disturbances. The drug can also cause gastrointestinal disturbances and arrhythmia. More rarely, severe hypersensitivity reactions including fatal bone marrow depression have been reported. (For use of carbamazepine in neuropathic pain Valproate is effective in all types of epilepsy and is especially useful in children and older people because it does not cause sedation and generally has low toxicity. It is considered to be first-line treatment for generalized seizures.

In skeletal muscle, the action of insulin increases uptake and use of glucose and increases synthesis of glycogen. In fat tissue, insulin increases glucose uptake and the use of glucose to form lipids and suppresses lipolysis.

Some stimulant laxatives, for example bisacodyl, can be given in suppository form for a rapid action within In some preparations, a stimulant laxative is combined with a softener or osmotic laxative, for example Picolax.

Resistance to antibiotics can develop by the following mechanisms: enzymes produced by bacteria destroy the drug; the bacterial cell wall becomes impermeable to a drug or the drug is rapidly removed; drug binding sites within bacteria become altered; alternative metabolic pathways develop in bacteria using enzymes not affected by the drug. The development of resistance can be reduced by less indiscriminate use of antibiotics, using them only where there is a distinct clinical need and ensuring that patients complete the entire course of antibiotics. This reduces the risk of survival and reproduction of resistant strains.
