Herbal Interactions with Cardiac Medications: A Comprehensive Review of Potential Interactions between Herbal Drugs and Commonly Prescribed Cardiac Medications.

BACKGROUND: The concomitant use of herbal remedies in conjunction with conventional cardiac medications has increased significantly in recent years, primarily due to improvements in the quality standards of herbal medicines and the pervasive belief that natural products pose no harm to the human body. Contrary to this belief, multiple phytoconstituents found in herbal products have the potential to interact with conventional cardiac drugs, potentially resulting in severe adverse effects.

Objective: This review aimed to elucidate the intricacies of these interactions highlighting herbal medications that interact with established pharmaceuticals used for the treatment of cardiovascular disorders. Moreover, the review draws attention to safety concerns and preventative steps that should be taken by patients and medical professionals.. This endeavor is vital to avert adverse events stemming from such interactions.

Methods: Our approach entailed a comprehensive literature review employing keywords such as "mechanisms of herb-drug interactions," "herbal medications," and "cardiovascular disorders." The drugs presented in this review were selected based on their popularity among the general population, frequency of their employability, and potential to manifest drug interactions. We sourced pertinent information from reputable databases, including PubMed, Scopus, and Elsevier.

Results: Heart or blood vessel disorders are referred to as cardiovascular diseases (CVDs), which include conditions such as heart failure, stroke, hypertensive heart disease, and peripheral arterial disease. The primary underlying factor for the development of CVDs is dyslipidemia, which can be treated with classical antihyperlipidemic drugs such as statins, ezetimibe, and PCSK9-inhibitors. The use of herbal remedies is often unregulated, and there is a lack of scientific evidence supporting their use, particularly in the management of heart failure. Patients may not disclose their use of herbal remedies to health care practitioners, which can result in potential harm.

Conclusion: Uncontrolled dyslipidemia leads to hypercholesterolemia, which can result in atherosclerotic plaques and blocked arteries and veins. Herbal remedies and botanical products are also used to prevent or treat illnesses, and many prescription pharmaceuticals are made from plant compounds. Herbal remedies are often preferred because of the belief that they are safe and have no potential to cause harm. However, there is insufficient scientific data to support the use of herbal remedies, especially when treating heart disease. Using herbal remedies in conjunction with medicinal pharmaceuticals may result in unfavorable effects.

Propolis: a wonder bees product and its pharmacological potentials.

Propolis is a natural resinous mixture produced by honey bees from substances collected from parts of plants, buds, and exudates. Due to its waxy nature and mechanical properties, bees use propolis in the construction and repair of their hives for sealing openings and cracks and smoothing out the internal walls and as a protective barrier against external invaders like snakes, lizards, and so forth, or against weathering threats like wind and rain. Bees gather propolis from different plants, in the temperate climate zone mainly from poplar. Current antimicrobial applications of propolis include formulations for cold syndrome (upper respiratory tract infections, common cold, and flu-like infections), wound healing, treatment of burns, acne, herpes simplex and genitalis, and neurodermatitis. Worldwide propolis has a tremendous popularity, but in India the studies over propolis have just started, not extensively reported except few regions of India like Maharashtra, West Bengal, Tamil Nadu, Gujrat, and Madhya Pradesh.

Development and evaluation of sustained release tablet of betahistine hydrochloride using ion exchange resin tulsion t344.

An attempt was made to sustain the release of Betahistine hydrochloride by complexation technique using strong cation-exchange resin, Tulsion T344. The drug loading onto ion-exchange resin was optimized for mixing time, activation, effect of pH, swelling time, ratio of drug : resin, and temperature. The resinate was evaluated for micromeritic properties and characterized using XRPD and IR. For resinate sustained release tablets were formulated using hydoxypropyl methylcellulose K100M. The tablets were evaluated for hardness, thickness, friability, drug content, weight variation, and in vitro drug release. Tablets thus formulated (Batch T-3) provided sustained release of drug over a period of 12 h. The release of Betahistine HCl from resinate controls the diffusion of drug molecules through the polymeric material into aqueous medium. Results showed that Betahistine HCl was formulated into a sustained dosage form as an alternative to the conventional tablet.

Itraconazole Niosomes Drug Delivery System and Its Antimycotic Activity against Candida albicans.

Niosomes have potential applications in topical drug delivery system. The objective of the study was to formulate and evaluate the niosome of Itraconazole. Surfactant : cholesterol ratio and quantity of ethanol used were studied by applying factorial design. Formulated niosomes were evaluated for vesicle size, entrapment efficiency, drug release, skin permeation, and antimycotic activity. Vesicle size, entrapment efficiency, and drug release were markedly dependent on surfactant : cholesterol ratio and quantity of ethanol used. Permeation of the drug through the skin was affected by cholesterol content in formulation. Itraconazole niosome were having larger zone of inhibition than marketed formulation when activity was checked against C. albicans. Niosomes may be a promising carrier for topical delivery of Itraconazole especially due to their simple production.
