Abstract:
A method and drug form are provided for increasing the oral absorption of glycosidic and related antibiotics such as macrolide, aminoglycoside, lincomycin and anthracycline antibiotics and related chemical species by the oral administration of said glycosidic and related antibiotics in a suitable pharmaceutically accepted excipient to which has been added a hydroxyaryl or hydroxyaralkyl acid or salt thereof. The hydroxyaryl or hydroxyaralkyl acid or salt thereof is present in the drug form in quantities sufficient to be effective in enhancing the rate of oral absorption of glycosidic and related antibiotic.
Abstract:
Dichloroamino acid derivatives other than .alpha.-dichloroamino acids are prepared from chlorination of corresponding amino acids, and are found to be potent germicidal and fungicidal agents.
Abstract:
Potassium is rendered nonbitter tasting by combining the same with phytic acid. The final product is useful as a nonbitter tasting potassium supplement for warm-blooded animals deficient in levels of potassium.
Abstract:
Drug-delivery device for releasing a drug at a continuous and controlled rate for a prolonged period of time is comprised of a shaped body of polymeric material containing a pharmaceutically acceptable drug and permeable to passage of the drug by diffusion. The polymeric material is an ethylene-vinyl acetate copolymer having a vinyl acetate content of about 4 to 80% by weight and a melt index of about 0.1 to 1000 grams per 10 minutes.
Abstract:
There is provided exceptionally stable and useful pro-drug forms of theophylline having the formula: ##STR1## wherein R represents a straight or branched phenylalkenyl group having 2-8 carbon atoms in the alkenyl portion.The compounds of this invention are useful in the treatment of asthma in warm-blooded animals. Upon administration, the compounds of this invention slowly go into solution and subsequently cleave prior to and/or during the absorption process, releasing theophylline in a sustained manner at a non-toxic, therapeutic level; that is, without the large blood level variations normally observed when theophylline per se is administered.

Abstract:
An ocular insert for the continuous controlled administration of a predetermined therapeutically effective dosage of drug to the eye over a prolonged period of time. The device meters the flow of drug by means of a drug release rate controlling material. The insert bioerodes in the environment of the eye concurrently with the dispensing or at a point in time after the dispensing of the therapeutically desired amount of drug.
Abstract:
There is provided, novel pro-drug forms of pyridinium aldoxime type cholinesterase reactivators, namely, dihydropyridinium aldoximes, having the formula: ##SPC1##Wherein R represents a member selected from the group consisting of an alkyl (C.sub.1 -C.sub.4) group, a ##SPC2##Group, a ##SPC3##Group, ##SPC4##Group, and a ##SPC5##Wherein Z represents a member selected from the group consisting of a --CH.sub.2 --CH.sub.2 -- group, a --CH.sub.2 --O--CH.sub.2 -- group, a --CH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 -- group, and a --CH.sub.2 O--CH.sub.2 --CH.sub.2 --O--CH.sub.2 -- group; wherein R.sub.1 represents a member selected from the group consisting of a hydrogen atom, a methyl group, an acyl group and a ##EQU1## group; and wherein X.sup.- represents an anion derived from a pharmaceutically acceptable acid addition salt.These compounds are useful in reactivating cholinesterase, inhibited following exposure to and/or ingestion of conventional anti-cholinesterase agents, especially in the brain.

Abstract:
Alkali and alkaline earth metal salts of salicylamide are administered in solid oral dosage forms with substantially improved analgesic, anti-inflammatory, antipyretic and sedative results as compared with salicylamide. Highest blood levels are obtained by administering enteric-coated salicylamide salt dosage forms.
