The effect of the drug on neuromuscular function was simultaneously assessed by electromyography. 2 Neostigmine was rapidly eliminated from plasma after intravenous administration. The decline in the plasma concentration of the drug was invariably resolved into two exponential components. The fast disposition (distribution) half‐life of the drug was invariably less than 1 min; the slow disposition (elimination) half‐life ranged from 15.4–31.7 min. 3 Neostigmine usually increased the amplitude of the compound muscle action potential and diminished electromyographic decrement within 2 min of intravenous injection. The pharmacological effect of neostigmine was usually maximal between 7 and 15 min. There was an inverse relationship between the plasma concentration of the drug and the facilitation of neuromuscular transmission. 4 Red cell acetylch...

The present study carries out a bibliographic review on the therapeutic tools available against oral candidiasis and their usefulness in each clinical situation. Material and Methods: Recent studies on treatment of oral candidiasis were retrieved from PubMed and Cochrane Library. Results: Nystatin and miconazole are the most commonly used topical antifungal drugs. Both antifungal drugs are very effective but need a long time of use to eradicate the infection. The pharmacological presentations of miconazole are more comfortable for patients but this drug may interact with other drugs and this fact should be assessed before use. Other topical alternatives for oral candidiasis, such as amphotericin B or clotrimazole, are not available in many countries. Oral fluconazole is effective in treating oral candidiasis that does not respond to topical treatment. Other systemic treatment alternatives, oral or intravenous, less used are itraconazole, voriconazole or posaconazole. Available novelties include echinocandins (anidulafungin, caspofungin) and isavuconazole. Echinocandins can only be used intravenously. Isavuconazole is available for oral and intravenous use. Other hopeful alternatives are new drugs, such as ibrexafungerp, or the use of antibodies, cytokines and antimicrobial peptides. Conclusions: Nystatin, miconazole, and fluconazole are very effective for treating oral candidiasis. There are systemic alternatives for treating recalcitrant infections, such as the new triazoles, echinocandins, or lipidic presentations of amphotericin B.
