The three-dimensional arrangement of atoms within a drug molecule that permits a specific binding interaction with a desired recep- tor is called the pharmacophore. The atoms that constitute the pharmacophore are a subset of all the atoms within the drug molecule. The pharmacophore is the bioactive face of the molecule and is that portion of the molecule that establishes intermolecular interactions with the receptor site. A pharmacophore is the assembly of geometric and electronic features required by a drug molecule to ensure both an optimal supramolecular interaction with its target receptor and the elicitation of a biological response. The term pharmacophore does not represent a single real molecule but a portion of a molecule. It is incorrect to name a structural skeleton, such as a phenothiazine or a prostaglandin, as a pharma- cophore. It is correct, however, to regard a pharmacophore as the common structural denominator shared by a set of bioactive molecules; the pharmacophore accounts for the shared molecular interaction capabilities of a group of structurally diverse drug molecules toward a common target receptor. For example, one bioactive face of acetylcholine permits interaction with a muscarinic receptor, while another bioactive face of acetylcholine permits interaction with a nicotinic receptor (section 4. The other portions of the drug molecule that are not part of the pharmacophore constitute molecular baggage.
Five drops of specific staphysagria in two ounces of water discount 4 mg medrol with amex arthritis back nerve pain, a teaspoonful every two hours it is said generic 16 mg medrol overnight delivery arthritis in neck icd 9 code, corrects many cases of night sweats in phthisis. Equal parts of the fluid extract and cologne water have been used successfully in cases of pediculus pubis and pediculus capitas. Dose, Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 170 from half a dram to one dram. Physiological Action—In overdoses it has produced biliousness, deranged stomach, an excessive secretion of mucus, or catarrh of the stomach and intestinal canal, loss of appetite, indigestion, fetid breath, irregular bowels and colic, with malaise and general indisposition to exertion. This agent was in great repute among very many of our older physicians as an alterative of special value. In syphilis, scrofula, and in all glandular derangements with general depravity of the system, marked blood dyscrasia and general impairment of the nutritive functions, this agent is indicated. Its influences are demanded in these cases more especially if there be tumidity and enlargement or distention of the abdominal structures with general atonicity, or in some cases in which there are persistently coated tongue and fetid breath. This is often the condition in which a patient is found following a protracted attack of intermittent fever— ague, and since the entire glandular system has become sluggish from the disease the tonic effects of this agent are here indicated. Its influence can be greatly heightened by the direct nerve tonics and calisaya in such cases as these. Therapy—When blood dyscrasia is present, sluggishness of the digestive apparatus, deficient glandular secretion, impaired secretion of the mucous membranes of the stomach and intestinal canal, this agent is indicated, as, in these cases, its tonic properties are plainly manifested. It is of value in imperfect restoration of these functions after protracted disease, on which it operates with the tonic and restorative stimulants to an excellent advantage. Amenorrhea, leucorrhea and dysmenorrhea, with relaxed condition of the uterine supports and prolapsus, sometimes occurring from the extreme debility following severe fevers, and common, also, with scrofula and other blood dyscrasias, are all materially benefited by corydalis formosa.

Two antidotes to ergot alkaloid overdose (prazosin and nitroprusside) are now available that were unavailable to patients described above (Au et al order 16mg medrol fast delivery arthritis relief neck pain. Nitroprusside should be avoided during pregnancy because it conjugates to cyanide and accumulates in the fetal liver buy medrol 4 mg cheap equine arthritis in back. If there is no specific antidote, a nonspecific aggressive treatment should be instituted as early as possible (see Appendix). Homicide and other injuries as causes of maternal death in New York City, 1987 through 1991. No tocolytic agent is uni- versally effective, although more than 100 000 pregnancies will receive tocolysis ther- apy. Pregnant women treated with tocolytics are at increased risk for serious cardiopulmonary com- plications that are directly attributed to the tocolytic drug. Tocolytic therapy invariably occurs outside embryogenesis, so congenital anomalies are not an issue. The primary concern is for adverse maternal, fetal, and neonatal effects (Sanchez-Ramos et al. The three principal indications that guide the use of tocolysis in the treatment of preterm labor are: (1) prophylaxis, (2) acute therapy, and (3) maintenance. Instances do exist when exposure to tocolytic agents occurs during organogenesis, and is used for other indications: terbutaline (asthma), indomethacin (pain), and nifedipine (hypertension). Use for these indications is discussed in the chapters on antiasthma (Chapter 5), analgesic (Chapter 8), and cardiovascular drugs (Chapter 3), respectively. Pharmacokinetics of tocolytic drugs Pharmacokinetic data on tocolytic drugs in pregnancy are limited to five studies of four drugs (Table 15.
