Summary
Consumers should be cautious of herbal products bought online, as they may contain undeclared, illegal pharmaceutical drugs. Analysis of Montalin® revealed hidden paracetamol and meloxicam, leading to product recalls.
Area of Science:
- Pharmacovigilance
- Herbal Medicine Safety
- Regulatory Affairs
Background:
- The internet offers numerous herbal preparations, some containing undisclosed active pharmaceutical ingredients.
- Undeclared substances in herbal products pose significant health risks due to potential interactions and adverse effects.
Observation:
- The Netherlands Pharmacovigilance Centre Lareb documented four adverse event reports linked to the Indonesian herbal product Montalin® in January 2021.
- Laboratory analysis confirmed the presence of effective quantities of paracetamol and meloxicam in Montalin® samples.
- These pharmaceutical substances were illegally added and not declared on the product's packaging.
Findings:
- Montalin® contained undeclared paracetamol and meloxicam, indicating illegal adulteration.
- The Dutch Food and Consumer Product Safety Authority (NVWA) mandated the cessation of sales by five online retailers of Montalin®.
Implications:
- Consumers purchasing herbal products online face risks from unlisted, potent pharmaceutical compounds.
- Increased vigilance and regulatory oversight are crucial for ensuring the safety of herbal preparations available through e-commerce channels.

Physical Properties of Amines
3.5K
Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.

Hallucinogens and Psychedelics
302
Hallucinogens are psychoactive substances that profoundly alter perceptual experiences, generating unreal visual and sensory images. Often referred to as psychedelic drugs — a term derived from the Greek words "psyche" (mind) and "delos" (revealing) — these substances include marijuana and lysergic acid diethylamide (LSD), among others. These drugs vary in intensity and effects.

Stimulants

Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Drug Classes and Categories
2.3K
Drugs can be classified according to their chemical composition or their intended therapeutic application. For instance, anti-infective agents that possess the ability to eliminate pathogens or suppress their growth and reproduction can be grouped based on the organisms they target or their chemical structure. Furthermore, drugs can be divided into prescription, nonprescription, or controlled substances. Prescription medications, such as antibiotics, require oversight from a licensed healthcare...

Antidotes
783
Antidotes are medicinal substances used to counteract the harmful effects of toxins or drugs in the body. They function in various ways, each uniquely designed to combat specific toxic compounds.
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...

CNS Stimulants: Psychedelic Agents
263
Hallucinogens, also known as psychedelic drugs, are a class of substances known for their ability to alter perception, cognition, and emotions. Despite their profound effects on the mind, these drugs are non-addictive, setting them apart from many other abused substances. The mechanism of action of these drugs lies in their impact on the 5-HT2A receptor in the brain. Upon activation, this receptor couples to Gq-type G proteins, triggering a cascade that releases intracellular calcium. This...
