Fluid therapy formulating

Formulate appropriate doses of medications involved in patient therapy and revise as needed. Patient parameters may change frequently, thus requiring different doses and/or medications. Examples include antibiotic therapy, sedatives, insulin, fluids, or vasopressors. 

The mainstay of treatment for cholera consists of fluid and electrolyte replacement with ORT to restore fluid and electrolyte losses. Rice-based rehydration formulations are the preferred ORT for cholera patients. In patients who cannot tolerate ORT, IV therapy with Ringer s lactate can be used. 

Mezlocillin, piperacillin, and ticarcillin are parenteral antibiotics formulated as sodium salts, so prescribers must consider the sodium content of these antibiotics when administering them to patients with congestive heart failure. During their distribution phase, antipseudomonal penicillins achieve orfly low concentrations in the cerebrospinal fluid. Consequently, antipseudomonal penicillins are not among the drugs of first choice for meningitis therapy. 

While a minority of therapeutic agents are inorganic electrolytes, it is nevertheless pertinent to consider the manner of their interaction with water. Electrolytes are, of necessity, components of replacement fluids, injections and eye drops and many other formulations. An increasing number of metal-containing compounds are used in diagnosis and therapy, some of which have interesting solution behaviour. 

Dmgs administered by the rectal route in suppositories are placed in intimate contact with the rectal mucosa, which behaves as a normal lipoidal barrier. The pH in the rectal cavity lies between 7.2 and 7.4, but the rectal fluids have little buffering capacity. As with topical medication, the formulation of the suppository can have marked effects on the activity of the drug. Factors such as retention of the suppository for a sufficient duration of time in the rectal cavity also influence the outcome of therapy the size and shape of the suppository and its melting point may also determine bioavailability. 

Many aspects of KD therapy are based more on lore than on scientific fact. For example, the diet duration, formulation, need for initial fast and fluid restriction, and optimal patient selection (age, seizure type, seizure etiology) have not been subject to scientific scrutiny. Many of these factors can be addressed using animal models, but surprisingly few experimental studies on the KD have been carried out (Stafstrom,...
