CEPHAMYCINS



CEPHAMYCINS
These are closely related to cephalosporins, but have a methoxy group at position 7 of β-lactam ring of 7-aminocephalosporanic acid nucleus. These are also produced by Streptomyces. The common cephamycins are Cefmetazole and Cefotetan which are similar in properties to II generation cephalosporins.
Moxalactam is a synthetic cephamycin which is similar in action to III generation cephalosporins.

Pharmacokinetics - Drug absorption and Transport of drugs across biological membranes

Transport of drugs across biological membranes All pharmacokinetic processes involved transport of the drug across biological membranes. Biological Membrane Biological membranes may be viewed as mosaics of functional units composed of lipoprotein complex. Most membranes are composed of a fundamental structure called the unit membrane or plasma membrane. This boundary, which is 80 to 100 A° thick, surrounds single cell and nuclei. More complex barriers such as the intestinal epithelia and the skin are composed of multiples of this functional structure. The plasma membrane consists of a bilayer of amphipathic lipids with their hydrocarbon chains oriented inward to form a continuous hydrophobic phase and their hydrophilic heads oriented outward. Individual lipid molecules in the bilayer can move laterally, endowing the membrane with fluidity, flexibility, high electrical resistance and relative impermeability to highly polar molecules. The known fluidity of the phospholipids i

Skeletal muscle relaxants

Skeletal muscle relaxants Physiology of SKM Contraction 1. Motor nerve impulse à 2. Release of ACh à 3. Binds with N M receptors at NMJ à 4. Depolarization & development of EPP at motor end plate (Mainly due to influx of Na + ) à 5. Muscle action potential (MAP) – contraction of SKM à 6. ACh is rapidly inactivated by ChE leading to repolarization à 7. Muscle is ready for a fresh nerve impulse. MECHANISM OF ACTION OF MUSCLE RELAXANTS Centrally acting muscle relaxants -           Reduce SKM tone by a selective action in the cerebrospinal axis, without altering consciousness. -           They selectively depress spinal and supraspinal polysynaptic reflexes involved in the regulation of muscle tone without significantly affecting monosynaptically mediated stretch reflex. -           Polysynaptic pathways in ascending reticular formation also depressed, though to a lesser extent. -           All centrally acting muscle relaxants have some sedative property

PHARMACOGNOSY - SOURCES AND COMPOSITION OF DRUGS

PHARMACOGNOSY - SOURCES AND COMPOSITION OF DRUGS             A large number of drugs are used in the clinics for the cure of various ailments. These drugs are diverse in chemical structure and are obtained from a wide variety of sources. In earlier days, simple chemical substances and different parts of plants were employed as medicinal agents, but most drugs currently used in therapeutics are synthetic in nature. However, natural sources are still used for obtaining some drugs mainly because their synthesis is difficult and uneconomical. Drugs are mainly obtained from following sources. I. NATURAL SOURCE A. Organic drugs . Organic drugs are mainly obtained from 1. Vegetable source 2. Animal source 3. Microorganisms. B. Inorganic drugs . These are mainly obtained from 1.   Metallic source 2.   Non-metallic source. II. SYNTHETIC SOURCE (I) NATURAL SOURCES OF DRUGS Active principles of drugs are mainly present in crude form in minute amounts. T
