Principles of Pharmacotherapy. ARNOLD P. FRIEDMAN, M.D. AND H. HOUSTON MERRITT, M.D. THERAPY OF HEADACHES by pharmacologic agents presents a variety of problems to the physician, particularly: alternative of drugs; indications for his or her use; dosages; and duration of treatment. Evaluation of the clinical ends up in the treatment of chronic headache with chemical agents is difficult, for we have a tendency to are coping with pain, which is a subjective response, the emotional reac¬tion associated with pain, and the threat of any symptom re¬lated to the head. Aloe Vera Veterinary Formula is made with stabilized Aloe Vera gel as its primary ingredient and is ideally suited for external skin problems. Furthermore, the interpretation of the results of the pharmacotherapy of pain isn’t reliable. As an example, 2 individuals may have identical pain thresholds, but respond quite differently to a drug administered for the relief of pain as a result of of the good distinction in their reaction to stress.

Treatment must to a great extent be empirical, and the selection of drugs depends upon the decision of the physician as to which he thinks will be the foremost appropriate and effective. It’s well-known that some patients respond better to 1 drug than to another, but we have a tendency to haven’t any proof to elucidate why this is often so. It’s difficult to determine how much of the improve¬ment will be attributed to the drug, that is, to the precise result of the chemical agent through physiologic mechanisms, as a result of psychologic factors also influence the results. Re¬sponse to a remedy will be littered with the physician-patient relationship, constitutional create-up and age of the patient, duration of symptoms, and the psychological state of the patient. Investigation of the results of treatment with medication will be made on 2 bases—subjective and objective. Subjective results are determined from the report of the patient, and the report of his family or friends. Its “no tears” formula makes Aloe Vera Liquid Soap a perfect shampoo for youngsters and adults alike. Sadly, there’s no entirely satisfactory technique of objectively evaluating the results of treatment as a result of headache is predominantly a subjective symptom. The employment of pulse volume tracing, elec-tromyography, and other procedures is of little value.

The subjective response of the patient is, therefore, the chief, though unsatisfactory, criterion. This reality is of importance within the statistical analysis of the efficacy of a replacement compound, but has little relevance within the treatment of any single patient. Placebos will be utilized in the evaluation of a replacement mode of therapy. In theory, any response obtained with patients taking the chemical agents (but not within the patients taking the placebo) should be due to the drug. In observe this concept quickly breaks down, as a result of placebos may have a significant and long-lasting effect.1 Since a placebo is pharmacologically inactive, the result must be due to psychologic factors attend¬ing its administration. It must be remembered that the reac¬tion to the pain, with the first sensation of pain, is being evaluated. Placebos, which cannot be expected to have an effect on the first sensation of pain, will manufacture an amelioration of the symptoms by inflicting a amendment within the patient’s reaction.
