Preformulation and Formulation Stability Studies
Preformulation studies, such as choice of the crystalline form of the drug and the excipients to be used in the dosage form, are very important for developing stable pharmaceutical products. Preformulation studies provide the initial data that help the formulator decide on possible dosage-form strategies. Because little time is allocated to this stage of drug development, especially in the current environment, it is essential that meaningful results be obtained from simple but rapid screening...
Adsorption onto and Absorption into Containers and Transfer of Container
Pharmaceuticals may interact with packaging and containers, resulting in the loss of drug substances by adsorption onto and absorption into container components and the incorporation of container components into pharmaceuticals. Diazepam in intravenous fluid containers and administration sets exhibited a loss during storage due to adsorption onto glass and adsorption onto and absorption into plastics.740 741 Nitroglycerin, a liquid with a significant vapor pressure, is also significantly...
Oil of Sassafras
Oil of sassafras is obtained from the root of Sassafras officinale, Nees et Eberm., a tree which grows in Virginia to a height of 20 to 30 feet, in Carolina to 100 feet. Although this tree is widely distributed in the eastern part of the United States, its distillation is mostly confined to Carrol Country, Tennessee. The supply is said to be exhausted throughout large areas, but sufficient remains to meet future demands, provided the price available will cover the cost of collection and...
Psychedelic Enemas
The rubber enema syringe is actually a South American Indian invention, but other suitable materials were also employed for the bulb. Intoxicating as well as medicinal enemas have been described both in the earliest European accounts of native customs, dating to the sixteenth century, and in the more recent ethnographic literature. Tobacco juice, ayahuasca Banisteriopsis caapi , and even a species of Anadenanthera A. colubrina whose seeds huiica or wilka were used for hallucinogenic snuff and...

The Food And Drug Bandits
Nearly 40 years ago that old warhorse for the protection of the American Public from spoiled and poisonous food and drugs the late Dr. Harvey W. Wiley had a fine law enacted for this purpose. But the Drug Trust got its hooks into the government bureau which was charged with enforcing the law soon after Dr. Wiley's death. This Bureau now known as the Food amp Drug Administration is used primarily for the perversion of justice by cracking down on all who endanger the profits of the Drug Trust....
Teenage Trends and Attitudes
Adolescent trends in drug use have been tracked for over 25 years. Researchers use this wealth of data to predict future drug trends and their possible implications for adolescent health and society at large. Patterns of drug use tend to be inversely related to perceived health risks. For example, in recent years, as knowledge of the health risks from cigarette smoking has increased, the number of teens who smoke has declined. This inverse relationship, however, has not been evident in LSD and...

Oil of Samphire
Samphire oil is distilled from Crithmum maritimum, L., a plant growing in France, Italy and Sardinia. Francesconi and Sernagiotto Gazz. 1912, 42, i, 185-93 have shown that the oil occurs in the assimilating tissues of the plant and is absent from the storage tissues. On account of the dill-apiole it contains, of which it forms an abundant source, the oil has strong physiological action, although it is not so active as oil of parsley, which contains apiole. The yield of oil from this plant has...

The aqueous DMSO layer is extracted with two...
Mescaline Lsd And Psilocybin Birds Of A Feather
Three of the most common hallucinogenic drugs used today are mescaline, LSD, and psilocybin. Some people insist that these three drugs produce the same psychological effects, and even some experienced users cannot tell the effects of each drug apart. Others, however, believe that the effects produced by psilocybin, LSD, or mescaline are unique. Several key pharmacological differences between these drugs are outlined in the table below the cerebral cortex. This region, which constitutes the bulk...
catalytic antibodies for treatment of drug abuse
Another experimental approach for the treatment of drug abuse is the use of catalytic antibodies. The idea behind this treatment is to create an artificial, antibody-based enzyme that can convert the parent drug to an inactive metabolite. This catalytic antibody would then be administered in medical emergencies for overdose or perhaps administered on a chronic basis to persons trying to withdraw from addiction to the drug. In the field of drug abuse, the possibility of using cocaine catalytic...
General Properties of Echinacea Species
The genus Echinacea, known as the purple coneflower, is represented by nine species found in the United States and in south central Canada. Three species, Echi-nacea purpurea, Echinacea angustifolia, and Echinacea pallida, are found in common herbal preparations and are used medicinally 24, 25 . Each shows different medicinal properties however, little has been done to compare the effectiveness of these species. The composition of each species of herb is similar with slight variations in the...
The Cereal Grains And Their Physical Properties
In a single gram of commercial rye, Secale cereale, there is an estimated cell count of 50,000-1 00,000 bacteria, more than 200,000 actinomyces, 12,000 fungi and a large number of yeasts. To sterilize one gram of grain would require, in effect, the destruction of more than 300,000 contaminants In a spawn jar containing in excess of a hundred grams of grain, and with the addition of water, the cell population soars to astronomical figures. Of all the groups of these organisms, bacteria are the...
Indoor Security
When growing indoors try to consider certain factors cropping up in the near future. Like visits from repairmen or gasmen. Some growers have a grow room which they can sweep clean in under 1 minute. This means that they have a closet near by where they can quickly move their plants too, if any visitors do pop up. Always keep your security closet near your grow area. It is no good walking around your house with five or more plants in your arms. It is a bad idea to use your toilet for the backup...
Fertilizers 1
Now we come to the confusing part about the guaranteed analysis of commercial fertilizer mixes, Federal and state laws require nutrient concentrations to appear prominently on the face of the fertilizer packages, even though the accuracy of the values is dubious. Do you think the N-P-K numbers on the label give the percentages of nitrogen, phosphorous, and potassium Well, yes and no. The scale measures nutrients with different scales. Nitrogen is listed as total combined elemental. Most...
Animal Models Of Anxiety
All preclinical animal models of anxiety involve exposing animals usually rats or mice to environmental stimuli that disrupt their normal pattern of behaviour Table 19.2 . Obviously, it can never be confirmed that animals are actually experiencing the equivalent of human anxiety and so the validity of all preclinical models rests largely on confirming that the change in behaviour is prevented by drugs that have established anti-anxiety effects in humans. An influential theory proposed by Gray...
About Electricity Consumption
It is not a crime to use electricity that has been legally purchased. No sensible judge would issue a search warrant on the basis of suspicious electricity consumption, However, not all judges are sensible, and small communities with bored police officers or special marijuana task forces often take it upon themselves to investigate whatever information they are able to weasel out of electric company employees. Larger police forces do not have the desire, time, or money to look for small-time...
Preparation of Tartaric Acid
My experience with the chemical scrutinizers while ordering a pound of Rochelle salts should serve as a lesson to those embarking upon LSD manufacture. Substances which are useful for this purpose will raise red flags if obtained through normal channels. It must then be the highest priority to avoid these normal channels, or to subvert their scrutiny by preparing yourself those substances with direct use in the synthesis. The most low-profile method for getting tartaric acid is to follow the...
Other Biological Activities

Hydroponic Systems
Passive hydroponic systems rely on capillary action to transfer the nutrient solution passively from the reservoir to the growing medium. The Dutch are masters of passive systems and achieve amazing results. Wick systems have no moving parts. Low initial cost and low maintenance enhance wick systems' popularity. Active hydroponic systems actively move the nutrient solution, which is usually recovered. Cannabis is a fast-growing plant and very well suited to active hydroponic systems. Ebb and...
Herpes Simplex Virus Infections
Two types of herpes simplex viruses HSVs can cause infections, HSV-1 and HSV-2. HSV-1 primarily affects the cornea causing herpes simplex keratitis. A variety of clinical manifestations such as infectious epithelial keratitis, follicular conjunctivitis, neurotrophic keratopathy, necrotizing stromal keratitis, immune stromal keratitis, and endothelitis are associated with HSV keratitis 11 . Neurotrophic keratopathy results mainly from decreased corneal innervations and tear secretion as a result...
Benzodiazepines
Benzodiazepine derivatives are a basic class of anxiolytics or tranquilizers compounds for treating conditions of general anxiety, and their synthesis and properties as such will be considered separately. However, despite the fact that the principal clinical effect of the benzodiazepines used in medicine is basically qualitatively identical, certain benzodiazepines are used for specific purposes other than relieving anxiety. In particular, representatives of this series of benzodiazepines such...

Analgesics
Analgesics are drugs which relieve pain without producing unconsciousness. This is accomplished by the ability of these drugs to exert a central depressant action on the optic thalimi of the brain. Most of the drugs listed also create antipyretic effects, along with their analgesic properties. Other than excessive sweating, this should not cause a problem for the recreational drug user. Some of the other drugs, however, do not possess the antipyretic effects. Morphine and its derivatives have...

I did not undergo the most extreme form of Bwiti initiation. The award for most extreme initiation goes, hands down, to the bad-ass Bwiti of the Mitsogho, who live in the southern reaches of Gabon. Before the ceremony, the hardcore Mitsogho shave off the initiate's hair. They pierce his tongue with a long needle. Then, after he has eaten iboga, his skull is hit with a hammer three times in order to break open the head, helping him enter the spirit world. In reports of visions from the Mitsogho...
Spectral Energy Distribution Of Solar Radiation
Most drug compounds and drug formulations will be subjected to light during production, storage, distribution, and use by the patient. It is obvious that various kinds of artificial light sources as well as sunlight present in rooms behind window glass may be major stress factors and therefore may initiate the degradation processes. Real room conditions will include large variances sunlight through the window may represent the worst case of stress on drugs. Generally, as a basis for...
Ganglioblocking Substances
Ganglioblockers are those compounds that selectively act on nerve transmission in the auto-nomic ganglia. Theoretically, ganglioblockers can stop all autonomic activity in the organism . These drugs are classified as depolarizing and antidepolarizing ganglioblockers. Depolarizing ganglioblockers such as nicotine initially stimulate postganglionic receptors, and then they block subsequent activation of the receptor, thus preventing repolarization of the postsynaptic membrane. The pharmacological...
Other Hypnotics And Sedative Drugs
Before benzodiazepines emerged as a class of drugs, a number of empirically discovered compounds were used in medicine as hypnotics. Among these were chloral hydrate, par-aldehyde, ethchlovinol, ethinamat, glutetimide, and methyprilone. Chloral hydrate Chloral hydrate, 2,2,2-trichloro-1,1-ethandiol 4.3.1 , is synthesized either by chlorination of ethanol or chlorination of acetaldehyde and the subsequent addition of water molecules to the resulting trichloroacetic aldehyde 31 .

Neurochemistry Of Gaba
The synthesis and metabolism of GABA is closely linked with that of glutamate and the citric acid or tricarboxylic acid TCA cycle Fig. 11.1 . GABA is produced by the decarboxylation of glutamate, a reaction catalysed by the enzyme glutamic acid decarboxylase GAD . GAD is found in several non-neuronal tissues including ovary and pancreas but within the CNS it is a specific marker of GABAergic neurons, where it is present in the cytoplasm as both soluble and membrane-bound forms, principally in...
ethylene diamine tetraacetate
The membrane of the cell can be disrupted by a variety of nonpolar substances. It is currently believed that this may be the site and mechanism of action of anesthesia gases such as diethyl ether and halothane. If the orderly arrangement of protein receptors and channels is disturbed nerve signal transmission will also be disrupted and unconsciousness can occur. Many fungicides are bacterial membrane disruptors. And recall that antibiotics like penicillin prevent the cell wall from being...
