The optimized Cinchonine gel effectively fights acne bacteria and is safe for twice-daily use.

This study examined the vasorelaxant effects of two similar alkaloids, chloroquine and cinchonine, in a model of smooth muscle contractions induced by phenylephrine. Results are not reported in the abstract.

This study evaluated the effectiveness and safety of a cinchonine nanostructured lipid carrier serum for hair growth in mouse models, finding that it significantly increased hair length and enhanced follicle penetration compared to controls, with no notable irritation observed.

This review examines the pharmacological potential of quinoline alkaloids from Cinchona bark for developing new drugs and cosmetics but reports no new findings.

This review explores the botany, traditional uses, phytochemicals, and pharmacological activities of Cinchona pubescens but presents no new clinical findings.

This study identified hypericin and berberine as compounds that can support hair growth by enhancing oxytocin receptor expression and acting as an oxytocin receptor agonist, respectively, potentially serving as practical alternatives to oxytocin for treating hair-loss diseases.

This review discusses current treatment strategies for alopecia and highlights the potential of lipid-based nanoparticles to improve drug delivery to the scalp and hair follicles, noting their ability to enhance skin penetration and drug stability while outlining associated challenges and the need for further research.

This study found that cromakalim and pinacidil significantly inhibited porcine detrusor muscle contractions, suggesting these ATP-sensitive potassium channel openers may have potential in treating certain bladder diseases.

Nitrendipine and nifedipine effectively block muscle contractions, while papaverine relaxes them and minoxidil needs high amounts to work.

In this clinical study, a serum containing Cinchona succirubra extract and Caffeine significantly improved hair growth and reduced hair loss in subjects with acute telogen effluvium.

In a study on hair loss treatment, researchers found that a serum containing Cinchona succirubra extract and caffeine improved hair density and reduced hair loss in individuals with acute telogen effluvium after 16 weeks of use, with significant improvements observable after just 4 weeks.

This study found that blocking GABA(A) receptors in cat dorsal horn neurons increased evoked activity and background discharge, highlighting differences in inhibitory control systems compared to glycine receptors.

This study evaluated a 20% cinchona extract cream and found it increased hair growth length and mass in guinea pigs, demonstrated good physical stability, and did not irritate rabbit skin.

This study found that Cinobufacin combined with chemotherapy improved clinical outcomes in breast cancer patients and reduced certain side effects compared to chemotherapy alone.

This study found that rapidly administered intravenous cimetidine may cause a significant drop in blood pressure in critically ill patients, whereas ranitidine does not appear to have the same effect.

This article discusses the use of direct vasodilators and sympatholytic agents in hypertension management, highlighting their utility in specific cases like refractory hypertension and heart failure, but reports no new clinical results.

New drugs like clonidine and prazosin show promise for treating high blood pressure despite some side effects.

This reference compilation details potential adverse skin reactions and other side effects associated with the antihypertensive drug Quinazil, including rare cases of skin angioedema and other dermatological reactions.

This study found that the alkaloids cepharanthine and berbamine bind to SK2 and SK3 channel subtypes with affinities that match their concentrations active against various diseases, prompting further investigation into SK channels' role in their therapeutic effects.

This report describes five cases where sudden akathisia occurred in female patients with bipolar disorder after a ziprasidone dose reduction, emphasizing potential unexpected side effects of second-generation antipsychotics.

Diazoxide, minoxidil sulphate, and cromakalim relax rat blood vessels by opening K+ channels, with some differences in their actions.

This article reviews the use of hydralazine, minoxidil, and sodium nitroprusside in managing hypertension and hypertensive crises, noting specific indications, adverse effects, and the adjunctive therapies needed to mitigate side effects.

This study found that Dex-loaded hyaluronic acid hydrogel microneedles significantly reduced pain in an acute inflammatory visceral pain model without sedation, suggesting a promising and patient-friendly alternative to intravenous delivery.

In this study, the pharmacological action of dobutamine on rabbit retinae was found to be distinct from that of other dopamine analogs like apomorphine and N-methyl-dopamine.

This review highlights cepharanthine as a promising candidate for COVID-19 treatment due to its antiviral activity against SARS-CoV-2 and favorable pharmacokinetic and safety profile, but reports no new clinical results.

This review discusses the historical development, mechanisms of action, and potential new clinical applications of the drug cepharanthine, highlighting its multi-faceted pharmacological properties; it reports no new clinical results.

This study found that several newly synthesized dihydrobenzopyran compounds inhibited insulin secretion and had vasorelaxant activity, with some more potent than reference KATP channel activators, though compound 21 functioned as a Ca2+ entry blocker.

Minoxidil is a new drug that lowers blood pressure.

This study found that octahydrobenzo[c]quinolizin-3-one derivatives, particularly compound 3, were potent and selective inhibitors of the enzyme 5α-reductase type 1.

This study found that minoxidil increased plasma renin activity in patients with hypertension through both an adrenergic mechanism related to heart rate changes and a secondary mechanism unrelated to propranolol.
